In your opinion would ‘privatization’ of the existing production units improve quality and productivity ? comment



A
Introduction:
Of late, there is much talk of privatization of some activities of the railways. The activities are broadly classified in to core and peripheral i.e. the running of trains and the allied activities like the maintenance of coaches and wagons, hospitals, schools, colleges, welfare activities like institutes etc. there is much talk on outsourcing the peripheral activities. As such, the talk of privatization of repair workshops is in the air. The recent Public private Partnership – PPP has given fillip to such schemes.

Before privatization of railways, the following points are to be seen.

Railways and Balanced Economic Development:
Railways in India have been the foremost agent of social transformation. The railway net work has changed the face of India. In the words of Shri P C Tandon,“ The Indian Railway System is almost a State with the State, with the largest industrial activity, the largest employer, a network of communications of track, telephone and telegraph that connects all parts of the country except the high Himalayas, moving vast number of peoples, traditionally peripatetic by nature, and quantities of goods chain of technologically advances manufacturing and maintenance units backed by it own research, development engineering and training institution of finance, higher training and teaching and consultation “. Prakash C Tandon, REPORT OF THE COMMITTEE TO STUDY ORGANISATIONAL STRUCTURE AND MANAGEMENT ETHOS OF INDIAN RAILWAYS”)

Railways As Pace Maker:
The Indian Railway as part of the Govt. of India has assumed of the entrepreneurial function to achieve the projected speed of economic development. Railway projects are of high cost and long gestation period. Therefore, the private sector will hardly invest in such projects, which eat away a large amount of profits. It is estimated that the cost of laying one Kilo Metre of B G rail link costs about Rs. 1 Crore. The KONKAN Railway is the best example to understand the magnitude of the cost of railway net work. Estimated to cost at Rs. 600 in 1990 now ended up with a cost of Rs. 3200 Crores in 1998.

Railways as Resource Generator:
For purpose of economic development, plenty of funds are required. Public Enterprises are meant to supplement the revenue of the State in a big way by appropriate pricing policies and by mopping up profits which otherwise may go to private sector. The Five Year Plans have pointed out the limitation of taxation for raising revenue and have alluded the need for raising revenues through Public Enterprises. The Third five-year Plan stated that in a developing economy the Public Enterprises constitute a ready and increasingly important source for financing investment either for the expansion of these enterprises, which yield these surpluses, or elsewhere in the economy.

Railways have paid dividend to the General Revenues much more than the investment made by the Govt. of India.

This is in addition to contributions to internal funds like Depreciation Reserve Fund (DRF), Development Fund (DF), Open Line Works Revenue (OLWR) and Capital over and above meeting the revenue expenditure.

Railways and National Allocation of Sources:
In many of the under developed countries, which are predominantly agricultural, over populated and under developed, resources are unevenly distributed among the people. The main reason for the expansion of Public Enterprises lies in the pattern of resource allocation decided upon under the Five Year Plans. In the Indian Railways the Capital expenditure is based on the National Planning Commission. For this purpose the Plan Heads maintained by the Planning Commission are incorporated in the Railways.

Public Enterprises as Means to Achieve Social Objectives:
A UN resolution stated that Public Enterprises plays an important and vital role in developing countries in as much as it helps in Capital Formation in fuller utilization or natural resource and in achieving a more equitable distribution of income and wealth. The Fourth Five Year Plan ,Second Draft described thus “Planning should result in greater equality in income and wealth that there should be progressive education of concentration of incomes wealth and economic power and that benefits of development should accrue more and more to the relatively less privileged classes of society and in particularly the Scheduled Castes and Scheduled Tribes whose economic and educational interests have to be promoted with special care“

Avoidance of Concentration of wealth and means of production: Railways as a Public Enterprise helped to promote national objectives as laid down in the Constitution that the ownership and control of material resources of the community does not result in concentration of wealth to the common detriment. Railways being the bulk carrier are the backbone of the Indian economy. If it were to be in the hands of the private sector, the country would have faced with enormous difficulties and the private sector would have dictated terms to the country’s premier transportation mode.

By treating the labour generously and by putting a comparatively low ceiling on the salaries and benefits at top level Public Enterprises has helped in reduction of disparities in income over a large area of employment. As on 31.03.2007, Railways employed 1.4 Million employees on the rolls and there are employment opportunities for every shade of jobs from software specialist to safaiwala from unskilled to specialized engineers, form clerk to financial analysts etc.

Help to the underprivileged: Public Enterprises has been used to promote the development of certain backward sections of the society, namely, the Scheduled Castes and Scheduled Tribes. During 1978 Public Enterprises was also asked to make reservations in appropriate lower levels in respect of deaf, blind, and orthopaedically handicapped. Railway as a trend setter introduced the Roster Point Programme to ensure the Scheduled Castes and Scheduled Tribes get promotion by allowing the policy of positive discrimination.
Further, as per the Central Govt.’s decision to extend the benefits of reservation in Jobs and Educational opportunities, Railways have earmarked percentage 27 for Other Backward Classes (OBC).

Railways and Innovation:
Public Enterprises have taken the responsibility to introducing certain new ideas in the process of management and administration. Accordingly, the Railway Ministry has spear headed certain Public Sector Undertakings:

Public Sector Undertakings:
Further, the following Public Sector Undertakings are also functioning under the Ministry of Railways.
1. Rail India Technical And Economics Services Ltd.(RITES)
2. Indian Railway Construction ( International) Ltd.(IRCON)
3. Container Corporation of India
4. Centre For Railway Information Systems
5. Indian Railway Finance Corporation.
6. Konkan Railway Corporation.

The installed capacity of machines: various types of machinery from wheel lathe to traverser are installed in the workshops. These are meant to increase the productivity of the artisan staff. Such machinery is gradually being upgraded with the help of Workshop modernization under COFMOW – Central Organization for Modernization of Workshops. In case of corporatisation/privatization of workshops would be laid waste. Already due to modernization in coach and wagon building, the maintenance work is getting reduced. In such a situation, the installed capacity of machinery is to be utilized even if it meant doing work for outsiders – other Govt. depts, Ministries; State Govt. works private companies, Port Trusts, corporations and private individuals.

The productivity of the labour: Railways being the largest employer of variety of skilled people large number of employees from unskilled to Master Craftsman exist in the workshops. In the past under steam loco scheme, the surplus employees were redeployed elsewhere. The trauma of the scheme still exists. The make use of the productive labour, the outside works can be executed in workshops as done by Defence workshops and Central workshop/Ponmalai. Such works can be profitably done by reducing the proforma on cost to maximum extent as per the guidelines given by the railway board in case of production units for enabling them to participate in the Global Tenders.

Safety concerns: Railways being the lifeline of the Indian economy, safety concerns ought to the first priority. The corporatisation/privatization of workshops might jeopardize the safety of the rolling stock.

Innovation and bench marking: To overcome such a disparaging situation, many production as well as repair workshops have shown keen interest in achieving bench marking and encouraging innovative ideas to increase the productivity of the workshop employees.

Modernization: Raiwlay workshops have been taken up for massive modernization programme. The centre for modernization of workshops (cofmow) is formed with this aim to modernize railway workshops. Through various programmes like modern machinery, redesigning of workshop layout, improved working conditions, provision of rest rooms, revision of assembly lines, improved traversers, modern cranes, modern painting facilities including poly urethane painting, etc the productivity of the workshops have definitely improved.
ISO certification: With changing scenario of globalization, the Indian railway workshops are gearing up to International standardization levels. Many workshops including production and repair workshops have obtained ISO certification, environmental certification etc for global competition and acceptance. The documentation process for ISO certification has identified the core and peripheral activities in workshops and the procedure for these activities have been laid down. Wherever necessary the outsourcing of the peripheral activities is done.

Conlusion: privatization/corporatisation of the railways have not paid fruitful results all over the world. From the british rail to Japanese rail the process was a fiasco. The story is similar to all other railways primarily the massive rail networks, the multitude of personnel to manage, the huge investment in developing infrastructure and rolling stock and the public demand to keep railways as a public utility and not as a commercial concern. Thus the Indian railway workshops are poised to great heights even without being privatized/corporatised and are on the threshold to take up even outside work to utilize the full installed capacity of the workshops.

ISO 9000
ISO 9000 is a family of standards for quality management systems. ISO 9000 is maintained by ISO, the International Organization for Standardization and is administered by accreditation and certification bodies. Some of the requirements in ISO 9001 (which is one of the standards in the ISO 9000 family) include
a set of procedures that cover all key processes in the business;
monitoring processes to ensure they are effective;
keeping adequate records;
checking output for defects, with appropriate corrective action where necessary;
regularly reviewing individual processes and the quality system itself for effectiveness; and
facilitating continual improvement
A company or organization that has been independently audited and certified to be in conformance with ISO 9001 may publicly state that it is "ISO 9001 certified" or "ISO 9001 registered." Certification to an ISO 9000 standard does not guarantee the compliance (and therefore the quality) of end products and services; rather, it certifies that consistent business processes are being applied.
Although the standards originated in manufacturing, they are now employed across a wide range of other types of organizations. A "product", in ISO vocabulary, can mean a physical object, or services, or software. In fact, according to ISO in 2004, "service sectors now account by far for the highest number of ISO 9001:2000 certificates - about 31% of the total." [1]
ISO 9001 certification does not guarantee that the company delivers products of superior (or even decent) quality. It just certifies that the company engages internally in paperwork prescribed by the standard. Indeed, some companies enter the ISO 9001 certification as a marketing tool.

//
ISO 9000 family
ISO 9000 includes the following standards:
ISO 9000:2000, Quality management systems - Fundamentals and vocabulary. Covers the basics of what quality management systems are and also contains the core language of the ISO 9000 series of standards. A guidance document, not used for certification purposes.
ISO 9001:2000 Quality management systems - Requirements is intended for use in any organization which designs, develops, manufactures, installs and/or services any product or provides any form of service. It provides a number of requirements which an organization needs to fulfill if it is to achieve customer satisfaction through consistent products and services which meet customer expectations. It includes a requirement for the continual (i.e. planned) improvement of the Quality Management System, for which ISO 9004:2000 provides many hints.
This is the only implementation for which third-party auditors may grant certification. It should be noted that certification is not described as any of the 'needs' of an organization as a driver for using ISO 9001 (see ISO 9001:2000 section 1 'Scope') but does recognise that it may be used for such a purpose (see ISO 9001:2000 section 0.1 'Introduction').
ISO 9004:2000 Quality management systems - Guidelines for performance improvements. covers continual improvement. This gives you advice on what you could do to enhance a mature system. This standard very specifically states that it is not intended as a guide to implementation.
There are many more standards in the ISO 9001 family (see "List of ISO 9000 standards" from ISO), many of them not even carrying "ISO 900x" numbers. For example, some standards in the 10,000 range are considered part of the 9000 family: ISO 10007:1995 discusses Configuration management, which for most organizations is just one element of a complete management system. ISO notes: "The emphasis on certification tends to overshadow the fact that there is an entire family of ISO 9000 standards ... Organizations stand to obtain the greatest value when the standards in the new core series are used in an integrated manner, both with each other and with the other standards making up the ISO 9000 family as a whole".
Note that the previous members of the ISO 9000 family, 9001, 9002 and 9003, have all been integrated into 9001. In most cases, an organization claiming to be "ISO 9000 registered" is referring to ISO 9001.
Contents of ISO 9001
ISO 9001:2000 Quality management systems — Requirements is a document of approximately 30 pages which is available from the national standards organization in each country.
Summary of ISO 9001:2000 in informal language
The quality policy is a formal statement from management, closely linked to the business and marketing plan and to customer needs. The quality policy is understood and followed at all levels and by all employees. Each employee needs measurable objectives to work towards.
Decisions about the quality system are made based on recorded data and the system is regularly audited and evaluated for conformance and effectiveness.
Records should show how and where raw materials and products were processed, to allow products and problems to be traced to the source.
You need a documented procedure to control quality documents in your company. Everyone must have access to up-to-date documents and be aware of how to use them.
To maintain the quality system and produce conforming product, you need to provide suitable infrastructure, resources, information, equipment, measuring and monitoring devices, and environmental conditions.
You need to map out all key processes in your company; control them by monitoring, measurement and analysis; and ensure that product quality objectives are met. If you can’t monitor a process by measurement, then make sure the process is well enough defined that you can make adjustments if the product does not meet user needs.
For each product your company makes, you need to establish quality objectives; plan processes; and document and measure results to use as a tool for improvement. For each process, determine what kind of procedural documentation is required. (Note: a “product” is hardware, software, services, processed materials, or a combination of these.)
You need to determine key points where each process requires monitoring and measurement, and ensure that all monitoring and measuring devices are properly maintained and calibrated.
You need to have clear requirements for purchased product.
You need to determine customer requirements and create systems for communicating with customers about product information, inquiries, contracts, orders, feedback and complaints.
When developing new products, you need to plan the stages of development, with appropriate testing at each stage. You need to test and document whether the product meets design requirements, regulatory requirements and user needs.
You need to regularly review performance through internal audits and meetings. Determine whether the quality system is working and what improvements can be made. Deal with past problems and potential problems. Keep records of these activities and the resulting decisions, and monitor their effectiveness. (Note: you need a documented procedure for internal audits.)
You need documented procedures for dealing with actual and potential nonconformances (problems involving suppliers or customers, or internal problems). Make sure no one uses bad product, determine what to do with bad product, deal with the root cause of the problem and keep records to use as a tool to improve the system.
2000 version
ISO 9001:2000 combines the three standards 9001, 9002, and 9003 into one, now called 9001. Design and development procedures are required only if a company does in fact engage in the creation of new products. The 2000 version sought to make a radical change in thinking by actually placing the concept of process management front and centre. ("Process management" was the monitoring and optimizing of a company's tasks and activities, instead of just inspecting the final product.) The 2000 version also demands involvement by upper executives, in order to integrate quality into the business system and avoid delegation of quality functions to junior administrators. Another goal is to improve effectiveness via process performance metrics — numerical measurement of the effectiveness of tasks and activities. Expectations of continual process improvement and tracking customer satisfaction were made explicit.
Future Version: 2008
TC 176, the ISO 9001 technical committee , has started its review on the next version of ISO 9001, which will in all likelihood be termed the ISO 9001:2008 standard, assuming its planned release date of 2008 is met. Early reports are that the standard will not be substantially changed from its 2000 version.
As with the release of previous versions, organizations registered to ISO 9001 will be given a substantial period to transition to the new version of the standard, assuming changes are needed; organizations registered to 9001:1994 had until December of 2003 to undergo upgrade audits.
Certification
ISO does not itself certify organizations. Many countries have formed accreditation bodies to authorize certification bodies, which audit organizations applying for ISO 9001 compliance certification. Although commonly referred to as ISO 9000:2000 certification, the actual standard to which an organization's quality management can be certified is ISO 9001:2000. Both the accreditation bodies and the certification bodies charge fees for their services. The various accreditation bodies have mutual agreements with each other to ensure that certificates issued by one of the Accredited Certification Bodies (CB) are accepted world-wide.
The applying organization is assessed based on an extensive sample of its sites, functions, products, services and processes; a list of problems ("action requests" or "non-compliances") is made known to the management. If there are no major problems on this list, the certification body will issue an ISO 9001 certificate for each geographical site it has visited, once it receives a satisfactory improvement plan from the management showing how any problems will be resolved.
An ISO certificate is not a once-and-for-all award, but must be renewed at regular intervals recommended by the certification body, usually around three years. In contrast to the Capability Maturity Model there are no grades of competence within ISO 9001.
Auditing
Two types of auditing are required to become registered to the standard: auditing by an external certification body (external audit) and audits by internal staff trained for this process (internal audits). The aim is a continual process of review and assessment, to verify that the system is working as it's supposed to, find out where it can improve and to correct or prevent problems identified. It is considered healthier for internal auditors to audit outside their usual management line, so as to bring a degree of independence to their judgments.
The TickIT guidelines are an interpretation of ISO 9000 produced by the UK Board of Trade to suit the processes of the information technology industry, especially software development.
AS 9000 is the Aerospace Basic Quality System Standard, an interpretation developed by major aerospace manufacturers. The current version is AS 9100.
PS 9000 is an application of the standard for Pharmaceutical Packaging Materials.
QS 9000 is an interpretation agreed upon by major automotive manufacturers (GM, Ford, Chrysler). It includes techniques such as FMEA and APQP. QS 9000 is now replaced by ISO/TS 16949.

Debate on the effectiveness of ISO 9000
The debate on the effectiveness of ISO 9000 commonly centres on the following questions:
Are the quality principles in ISO 9000:2000 of value? (Note that the version date is important: in the 2000 version ISO attempted to address many concerns and criticisms of ISO 9000:1994.)
Does it help to implement an ISO 9001:2000 compliant quality management system?
Does it help to obtain ISO 9001:2000 certification?
Advantages
It is widely acknowledged that proper quality management improves business, often having a positive effect on investment, market share, sales growth, sales margins, competitive advantage, and avoidance of litigation.[4][5] The quality principles in ISO 9000:2000 are also sound, according to Wade,[6] and Barnes, [5] who says "ISO 9000 guidelines provide a comprehensive model for quality management systems that can make any company competitive." Barnes also cites a survey by Lloyd's Register Quality Assurance which indicated that ISO 9000 increased net profit, and another by Deloitte-Touche which reported that the costs of registration were recovered in three years. According to the Providence Business News [7], implementing ISO often gives the following advantages:
Create a more efficient, effective operation
Increase customer satisfaction and retention
Reduce audits
Enhance marketing
Improve employee motivation, awareness, and morale
Promote international trade
Increases profit
Reduce waste and increases productivity
However, a broad statistical study of 800 Spanish companies [8] found that ISO registration in itself creates little improvement because companies interested in ISO have usually already made some type of commitment to quality and were performing just as well before registration.[4]
In today's service sector driven economy, more and more companies are using ISO 9000 as a business tool. Through the use of properly stated quality objectives, customer satisfaction surveys and a well-defined continual improvement program companies are using ISO 9000 processes to increase their efficiency and profitability.
Problems
A common criticism of ISO 9001 is the amount of money, time and paperwork required for registration.[9] According to Barnes, "Opponents claim that it is only for documentation. Proponents believe that if a company has documented its quality systems, then most of the paperwork has already been completed."[5]
According to Seddon, ISO 9001 promotes specification, control, and procedures rather than understanding and improvement. [2] [3] Wade argues that ISO 9000 is effective as a guideline, but that promoting it as a standard "helps to mislead companies into thinking that certification means better quality, ... [undermining] the need for an organization to set its own quality standards." [6] Paraphrased, Wade's argument is that total, blind reliance on the specifications of ISO 9001 does not guarantee a successful quality system.
The standard is seen as especially prone to failure when a company is interested in certification before quality.[2] Certifications are in fact often based on customer contractual requirements rather than a desire to actually improve quality.[5][10] "If you just want the certificate on the wall, chances are, you will create a paper system that doesn't have much to do with the way you actually run your business," said ISO's Roger Frost.[10] Certification by an independent auditor is often seen as the problem area, and according to Barnes, "has become a vehicle to increase consulting services." [5] In fact, ISO itself advises that ISO 9001 can be implemented without certification, simply for the quality benefits that can be achieved. [11]
Another problem reported is the competition among the numerous certifying bodies, leading to a softer approach to the defects noticed in the operation of the Quality System of a firm.
Summary
A good overview for effective use of ISO 9000 is provided by Barnes: [5]
"Good business judgment is needed to determine its proper role for a company... Is certification itself important to the marketing plans of the company? If not, do not rush to certification... Even without certification, companies should utilize the ISO 9000 model as a benchmark to assess the adequacy of its quality programs."
ISO 10006
ISO 10006:2003, Quality management systems - Guidelines for quality management in projects, is an international standard developed by the International Organization for Standardization.
ISO 10006:2003 gives guidance on the application of quality management in projects.
It is applicable to projects of varying complexity, small or large, of short or long duration, in different environments, and irrespective of the kind of product or process involved. This can necessitate some tailoring of the guidance to suit a particular project.
ISO 10006:2003 is not a guide to "project management" itself. Guidance on quality in project management processes is discussed in this International Standard. Guidance on quality in a project's product-related processes, and on the "process approach", is covered in ISO 9004.
Since ISO 10006:2003 is a guidance document, it is not intended to be used for certification/registration purposes.
ISO 14000

The ISO 14000 environmental management standards exist to help organizations minimize how their operations negatively affect the environment (cause adverse changes to air, water, or land), comply with applicable laws and regulations.
ISO 14001 is the international specification for an environmental management system (EMS). It specifies requirements for establishing an environmental policy, determining environmental aspects and impacts of products/activities/services, planning environmental objectives and measurable targets, implementation and operation of programs to meet objectives and targets, checking and corrective action, and management review.
ISO 14000 is similar to ISO 9000 quality management in that both pertain to the process (the comprehensive outcome of how a product is produced) rather than to the product itself. The overall idea is to establish an organized approach to systematically reduce the impact of the environmental aspects which an organization can control. Effective tools for the analysis of environmental aspects of an organization and for the generation of options for improvement are provided by the concept of Cleaner Production.
As with ISO 9000, certification is performed by third-party organizations rather than being awarded by ISO directly. The ISO 19011 audit standard applies when auditing for both 9000 and 14000 compliance at once.
Standards
The material included in this family of specifications is very broad. The major parts of ISO 14000 are:
ISO 14001 is the standard against which organizations are assessed. ISO 14001 is generic and flexible enough to apply to any organization producing and/or manufacturing any product, or even providing a service anywhere in the world.
ISO 14004 is a guidance document that explains the 14001 requirements in more detail. These present a structured approach to setting environmental objectives and targets and to establishing and monitoring operational controls.
These are further expanded upon by the following:
ISO 14020 series (14020 to 14025), Environmental Labeling, covers labels and declarations.
ISO 14030 discusses post-production environmental assessment.
ISO 14031 Evaluation of Environmental Performance.
ISO 14040 series (14040 to 14044), Life Cycle Assessment, LCA, discusses pre-production planning and environment goal setting.
ISO 14050 terms and definitions.
ISO 14062 discusses making improvements to environmental impact goals.
ISO 14063 is an addendum to 14020, discussing further communications on environmental impact.
ISO 14064-1:2006 is Greenhouse gases – Part 1: Specification with guidance at the organization level for the description, quantification and reporting of greenhouse gas emissions and removals.
ISO 14064-2:2006 is Greenhouse gases – Part 2: Specification with guidance at the project level for the description, quantification, monitoring and reporting of greenhouse gas emission reductions and removal enhancements.
ISO 14064-3:2006 is Greenhouse gases – Part 3: Specification with guidance for the validation and verification of greenhouse gas assertion.
ISO 19011 which specifies one audit protocol for both 14000 and 9000 series standards together. This replaces ISO 14011 meta-evaluation—how to tell if your intended regulatory tools worked. 19011 is now the only recommended way to determine this.

GANTT CHART
A Gantt chart showing three kinds of schedule dependencies and percent complete indications.
A Gantt chart is a popular type of bar chart that illustrates a project schedule. Gantt charts illustrate the start and finish dates of the terminal elements and summary elements of a project. Terminal elements and summary elements comprise the work breakdown structure of the project. Some Gantt charts also show the dependency (i.e., precedence network) relationships between activities. Gantt charts can be used to show current schedule status using percent-complete shadings and a vertical "TODAY" line as shown here.

//
Historical development
The first Gantt Chart was developed by Karol Adamiecki, who called it a Harmonogram. Because Adamiecki did not publish his chart until 1931, this famous chart bears Gantt's name] Henry Gantt (1861–1919) designed his chart in 1910.
In the 1980s, personal computers eased the creation and editing of elaborate Gantt charts. These desktop applications were intended mainly for project managers and project schedulers. In the late 1990s and early 2000s, Gantt charts became a common feature of web-based applications, including collaborative groupware.
Although now considered a common charting technique, Gantt charts were considered quite revolutionary when they were introduced. In recognition of Henry Gantt's contributions, the Henry Laurence Gantt Medal is awarded for distinguished achievement in management and in community service.

Advantages and limitations
Gantt charts have become a common technique for representing the phases and activities of a project work breakdown structure (WBS), so they can be understood by a wide audience.
A common error made by those who equate Gantt chart design with project design is that they attempt to define the project work breakdown structure at the same time that they define schedule activities. This practice makes it very difficult to follow the 100% Rule. Instead the WBS should be fully defined to follow the 100% Rule, then the project schedule can be designed.
Although a Gantt chart is easily comprehended for small projects that fit on a single sheet or screen, they can become quite unwieldy for projects with more than about 30 activities. Larger Gantt charts may not be suitable for most computer displays. A related criticism is that Gantt charts communicate relatively little information per unit area of display. That is, projects are often considerably more complex than can be communicated effectively with a Gantt chart.
Gantt charts only represent part of the triple constraints of projects, because they focus primarily on schedule management. Moreover, Gantt charts do not represent the size of a project or the relative size of work elements, therefore the magnitude of a behind-schedule condition is easily miscommunicated. If two projects are the same number of days behind schedule, the larger project has a larger impact on resource utilization, yet the Gantt does not represent this difference.
Although project management software can show schedule dependencies as lines between activities, displaying a large number of dependencies may result in a cluttered or unreadable chart.
Because the horizontal bars of a Gantt chart have a fixed height, they can misrepresent the time-phased workload (resource requirements) of a project. In the example shown in this article, Activities E and G appear to be the same size, but in reality they may be orders of magnitude different. A related criticism is that all activities of a Gantt chart show planned workload as constant. In practice, many activities (especially summary elements) have front-loaded or back-loaded work plans, so a Gantt chart with percent-complete shading may actually miscommunicate the true schedule performance status.

ENERGY AUDIT
An energy audit is an inspection, survey and analysis of energy flows in a building, process or system with the objective of understanding the energy dynamics of the system under study. Typically an energy audit is conducted to seek opportunities to reduce the amount of energy input into the system without negatively impacting the output(s). When the object of study is an occupied building then reducing energy consumption while maintaining or improving human comfort, health and safety are of primary concern. Beyond simply identifying the sources of energy use, an energy audit seeks to prioritize the energy uses according to the greatest to least cost effective opportunities for energy savings.

Industrial & Agricultural Energy Audits
Increasingly in the last several decades, industrial and agricultural energy audits have exploded as the demand to lower increasingly expensive energy costs and move towards a sustainable future have made energy audits popular.
Types of Energy Audit
There are three common audit programs.
Preliminary Audit
The preliminary audit (alternatively called a simple audit, screening audit or walk-through audit) is the simplest and quickest type of audit. It involves minimal interviews with site-operating personnel, a brief review of facility utility bills and other operating data, and a walk-through of the facility to become familiar with the building operation and to identify any glaring areas of energy waste or inefficiency. Typically, only major problem areas will be uncovered during this type of audit. Corrective measures are briefly described, and quick estimates of implementation cost, potential operating cost savings, and simple payback periods are provided. This level of detail, while not sufficient for reaching a final decision on implementing a proposed measures, is adequate to prioritize energy-efficiency projects and to determine the need for a more detailed audit.

General Audit
The general audit (alternatively called a mini-audit, site energy audit or complete site energy audit) expands on the preliminary audit described above by collecting more detailed information about facility operation and by performing a more detailed evaluation of energy conservation measures. Utility bills are collected for a 12 to 36 month period to allow the auditor to evaluate the facility's energy/demand rate structures and energy usage profiles. If interval meter data is available, the detailed energy profiles that such data makes possible will typically be analyzed for signs of energy waste. Additional metering of specific energy-consuming systems is often performed to supplement utility data. In-depth interviews with facility operating personnel are conducted to provide a better understanding of major energy consuming systems and to gain insight into short and longer term energy consumption patterns.
This type of audit will be able to identify all energy-conservation measures appropriate for the facility, given its operating parameters. A detailed financial analysis is performed for each measure based on detailed implementation cost estimates; site-specific operating cost savings, and the customer's investment criteria. Sufficient detail is provided to justify project implementation.
Investment-Grade Audit
In most corporate settings, upgrades to a facility's energy infrastructure must compete for capital funding with non-energy-related investments. Both energy and non-energy investments are rated on a single set of financial criteria that generally stress the expected return on investment (ROI). The projected operating savings from the implementation of energy projects must be developed such that they provide a high level of confidence. In fact, investors often demand guaranteed savings.
The investment-grade audit (alternatively called a comprehensive audit, detailed audit, maxi audit, or technical analysis audit) expands on the general audit described above by providing a dynamic model of energy-use characteristics of both the existing facility and all energy conservation measures identified. The building model is calibrated against actual utility data to provide a realistic baseline against which to compute operating savings for proposed measures. Extensive attention is given to understanding not only the operating characteristics of all energy consuming systems, but also situations that cause load profile variations on short and longer term bases (e.g. daily, weekly, monthly, annual). Existing utility data is supplemented with submetering of major energy consuming systems and monitoring of system operating characteristics.
Impact on railway workshops:
The railway workshops by implementing energy audit can greatly reduce the energy in production units and repair workshop. At a time when the unit cost of repair and manufacturing cost is on the increase, the energyu audit wil help the reduction in the cost of inputs and enable the participation of production units in global tenders for manufacture.
