FOREWORD
This Indian Standard was adopted by the Bureau of Indian Standards, after the draft finalized by the StatisticalMethods for Quality and Reliability Sectional Committee had been approved by the Management and SystemsDivision Council.
Benchmarking is simply the process of measuring the performance of one’s company against the best in the sameor another industry. It is often stated that those who benchmark do not have to reinvent the wheel. By followingothers one can make improvements and not focus on stale ideas. The knowledge that is available for comparingoperations and processes are vast. An organization’s ability to evaluate its practices against specific businessstrategies and objectives is critical to leveraging its knowledge capital. It is the process of using all of theknowledge and experience of others to develop new and fresh ideas. This is basic teamwork, which is the wayprogressive organizations are migrating. Many organizations are realizing how much more can be achieved, ifthere is more collaboration between leaders in an industry.
The composition of the Committee responsible for the formulation of this standard is given in Annex E.
This standard has been prepared to provide guidance in circumstances where a study is necessary to comparea process against those of recognized leaders to provide opportunities for improvement. It is a way of measuringa firm’s strategies and performance against top firms, both inside and outside the industry.

Title
Methods of estimation of processcapability and process performance(second revision)
3 TERMINOLOGY
3.1 Benchmark — A measured, best-in-classachievement; a reference or measurement standard forcomparison; this performance level is recognized asthe standard of excellence for a specific businessprocess.
3.2 Benchmarking — The process of identifying,learning, and adapting outstanding practices, methodsand processes from any organization, anywhere in theworld, to help an organization improve its performance.
3.3 Best Practice — There is no single best practicebecause best is neither best for everyone nor for alltimes. Every organization is different in some way—different missions, cultures, environments andtechnologies. What is meant by best are those practicesthat have been shown to produce superior results:selected by a systematic process, and judged as exemplary,good or successfully demonstrated. Best practices arethen adapted to fit a particular organization.
3.4 Functional — Process benchmarking that comparesa particular business benchmarking function at two ormore companies. It is a process of comparison ofspecific functions like distribution, logistics, etc, withbest in class organizations which are not in the sameindustry. Teams from process areas usually conduct it.Resource requirement is high.
Examples:1) Benchmarking of customer complaint handling
process of two different organizations.
2) Inventory management systems of twoorganizations.
3.5 Generic Benchmarking — Process benchmarkingthat compares a particular business fimction or processat two or more companies independent of their industries.It is similar to tlmctionai benchmarking except that itfocuses on comparison of generic business processesof other companies who are judged to have innovativeprocesses. It is the latest evolutionary stage ofbenchmarking.
Examples:
1) Remington division benchmarking its surface
S1 No. Inventory Management Vehicle Manufacturing Unit Versus
Watch Manufacturing Unit
(1) (2) (3)
i) Advantages a] High potential for discovering innovative practices
b) Development of professional network
c) Access to relevant database
ii) Disadvantages a) Difficulty in transferring practices
b) Some information not transferable
c) Time consuming

2) Material collection system with milk distributionby milk vendor.
3.6 Global Benchmarking — The extension of strategicbenchmarking to a global scale.
3.7 Internal Benchmarking —-Process benchmarkingthat is performed within an organization by comparingsimilar business units or business processes. It is aprocess of site-to-site learning for an organization havingmore than one unit.
Examples: -+
1) Maintenance practices of two different units ofvehicle manufacturing unit.
2) Productivity of foundry and contract processingsystem of two different units of vehiclemanufacturing unit.
S1 No. Advantages Disadvantages
(1) (2) (3)
i) Data easy to collect Limited focus
ii) Good results for Internal biasdiversified company
3.8 Competitive Benchmarking — This type ofbenchmarking involves specific competitor-to-competitorcomparisons for processes of interest.
Examples:
1) Benchmarking of the processes of two differentsteel producing organizations.
2) Benchmarking of manufacturing productivity oftwo car plant.
S1 No. Advantages Disadvantages
(1) (2) (3)
i) Information relevant Data collectionto business results diftlculties
3.9 Co-operative and Collaborative Benchmarking —It is most widely used type of benchmarking because itis relatively easy to practice. It is a more accommodatingway of getting information. In co-operative benchmarkinginformation flows one way. In collaborative benchmarkinginformation is shared between groups of firms. Not allcollaborative efforts are considered benchmarking. Datasharing results do not focus on the process but only onthe end results, while benchmarking focuses on theprocesses of the organizations.
3.10 Key Business Process — Those processes thatinfluence the customer’s perception of your business.
3.11 Process — A series of inter related activities thatconvert input into results (outputs); processes consumeresources and require standards for repeatableperformance; proce$ses respond to control systemsthat direct the quality, rate, and cost of performance. Itcan also be seen as a repeatable sequence of steps usedto transform an input into an output that has value toan internal or external customer.
Examples:
Lawn mowing process:
1) mower prepared,
2) lawn mowed,
3) grass clippings disposed, and
4) mower stored.
3.12 Practice — A method or technique used to performa process step. Practices describe how we perform astep within a work process.
Examples:
1) self-propelled lawn mower and rectangular mowingpattern, or
2) hand-pushed mower.
3.13 Metric — A metric qualifies the effect of installingand using one or more practices.
Examples:
Assuming you are concerned with fuel use, you maymeasure:
1) cost per gallon, and
2) number of tanks filled per lawn.
3.14 Enabler — Any condition or factor that influencesthe effectiveness of a practice is called enabler.
Examples:
Condition of lawn, trai~ing and experience of mower,instructions on mower operation.
3.15 Performance Benchmarking — The analysis ofrelative business performance among competitors isperformance benchmarking. Uses open-literature analysisor conducted as blind studies with third party assistance.The resource requirement is low. Can use trained companypersonnel or consultants.
3.16 Engineering — The radical redesign of business
processes, organizational structures, managementsystems, and values of an organization to achievebreakthroughs in business performance.
3.17 Reverse Engineering — A comparison of the
2
product characteristics, functionality, and performancewith similar products made by competitors is reverseengineering.
3.18 Strategic Benchmarking — A systematic businessprocess for evaluating alternatives, implementingstrategies, and improving performance by understandingand adapting successful strategies from external partnerswho participate in an on-going strategic alliance. Strategicbenchmarking deals with top management. It deals withlong-term results. It focuses on how companies compete.It involves analysis of world class companies in non-competitive industries to determine opportunities forstrategic change initiatives in core business processes.Usually is performed by trained benchmarking personnel.Resource requirement is medium-low.
3.19 World Class - Leading performance in a processindependent of industry, function, or location in world.World class manufacturers are those that demonstrateindustry best practice, To achieve this, companies shouldattempt to be best in the field at each of the competitivepriorities (quality, price, delivery speed, reliability andflexibility).Organizations should therefore aim to maximizeperformance in these areas in order to maximizecompetitiveness. However, as resources are unlikely toallow improvement in all areas, organizations shouldconcentrate on maintaining performance in quali~ingfactors and improving competitive edge factors. Thepriorities will change over time and must therefore bereviewed,
4 APPLICATION

5.5 Ways to Conduct Benchmarking
5.5.1 In-house Research
This usually occurs when the organization is onlyseeking information about performance results.
5.5.2 Third Party Research
It is usually needed for obtaining hard to get informationabout direct competitors or for conducting forums(focus /panel groups) of multiple institutions convenedto gather a wide range of input.
5.5.3 Direct Exchange
A direct exchange of information such as a questionnaireor a telephone conference is an important step prior toconducting a direct site visit.
5.5.4 Direct Site Visits
One or more face-to-face sessions between benchmarking
teams to provide interactive discussion, exchange andelaboration on benchmarking information. Direct sitevisits are the most interesting and effective way toconduct benchmarking.
5.6 Approach to Benchmarking

6 CODE OF CONDUCT
6.1 General
Benchmarking can be fraught with potential problems,ranging from simple misunderstandings to seriouslegal problems. To minimize the likelihood of thesetypes of difficulties the teams should follow the simplecode of conduct scripted by the InternationalBenchmarking Clearinghouse.
6.2 Legality
Don’t enter into discussions or act in any way thatcould be construed as illegal, either for you or yourpartner. Potential illegal activities include, for example,
s‘,,.*‘#,,
.
4
such simple actions as discussing costs or prices, ifthat discussion could lead to allegations of price fixingor market rigging. The process of how you arrive atprices may be acceptable, while discussion of actualcosts and prices may not.
6.3 Exchange
Don’t ask questions of your benchmarking partnerthat you are not willing to answer yourself to the samelevel of detail. It helps to fully disclose your level ofexpectations with regard to the exchange early on inyour discussion.
6.4 Confidentiality
Treat the information you receive from your partnerswith the same degree of care that you would for theinformation that is proprietary to your organization.Many organizations may not even want you to disclosethat you have had such discussions with them. In thisregard, you may want to consider entering a non-disclosure agreement with your benchmarking partner;consult your legal staff.
6.5 Use of Information
Don’t use the benchmarking information you receivefrom a partner for any other purpose other than towhich you have agreed.
6.6 Contact
Don ‘t go beyond the mutually agreed-on proceduresthat govern whom you will interact with in your partner’sorganization. Comply with their wishes and culture.
6.7 Preparation
Be prepared for your meetings and exchanges. Doingso increases your efficiency and effectiveness, andthat of your partners as well. It promotes an air ofprofessionalism.
IS 15564:2005
6.8 Completion
Don’t make commitments you can’t or don’t keep.Complete your work to every one’s satisfaction, includingthat of your partner.
6,9 Understanding
Benchmarking’s Golden Rule; treat your partner andtheir information the way you would like them to treatyou and yours.
