1. Operational Analysis of a Process
This involves breaking the processes in 4 segments:
• Who?• What?• How?• Where?
Who is performing the task ?
• Reveals hidden organizational problems
• Shows division of responsibility and authority
• Communication issues
• Skill base and experience
• Decision making power
• Technical vitality
1. Operational Analysis of a Process
What task is done ?
• Helps in redistribution of task
• Elimination of waste and unnecessary task
• Proper utilization of skills
• Consolidation of group activities
• Elimination of wasted efforts
• Correct skill deficiencies
• Task dependencies
• Time utilization

Principles
Techniques of waste reduction a )Value-added assessment b) Eliminating non-value adding activities c) Minimize checks and inspections d) Minimize administrative tasks e) Minimize storage and transportation activities
1. Waste reduction
Value added assessment
Value to customer : First, the customer’s view point should be considered. The customers are only interested in receiving the product or service that satisfies their requirements. All activities that must be performed to cater to the customer’s requirements are value -added activities.
Does the activity add value to the customer ?
Would any customer care if the activity was not performed ?
Would any customer object if the activity was not performed ?
Do the customers appreciate the results of the activity?
Eliminate non-value adding activities
Value to business : There are many activities that may not add value from the customer’s point of view. Attending meetings, developing plans, compliance with regulatory guidelines, writing procedures etc are examples of activities that may not add value to the customers, but they do add value to the organization. Each of these activities must be carefully examined.
Minimize checks & inspections
• Checks and inspections may be necessary in a process, however they do not add value to the process. Each inspection point should be identified and challenged.
• The next slide lists some questions to use in this challenge.
What if the inspection was eliminated?
• What if the inspection was eliminated?
• Would the inspection be missed?
• What is the potential impact in eliminating the inspection?
• What potential consequences exist if the inspection is eliminated?
• What is the likelihood that the inspection would have revealed a problem?
Administrative tasks often result in delays in process time due to excessive paper work, levels of reviews and multiple signatures (mostly by people who, it seems, are never available when needed). Reviews, approvals, signatures, preparing written documentation, making and distributing copies etc needs to be thoroughly reviewed..
Minimize administrative tasks
Minimize storage and transportation activities
Sometimes storage and transportation are necessary evils but because they are both non-value adding they should be minimized. The purpose of just-in-time inventory systems to minimize the amount of inventory stored.
Transportation activities are also non-value adding. Often the relocation of single activity can significantly reduce the transportation requirements.
Minimize storage and transportation activities
2. Process simplification
Simplification means reducing the complexities of process. Simplification can lead to lessor activities and lessor things to go wrong. Process simplification can be done by combining similar activities and by analyzing decision points.
2. Process simplification
Efforts should focus on reducing layers of management and structures that cause delays. Outdated systems and procedures need to be evaluated.
3. Cycle-time reduction
Cycle-time is the time required to deliver a product or service to a customer. Long cycle-times not only prevent prompt delivery of product/ service to your customers, but also increase costs. One of the best ways to cut down on your cycle-time is to conduct activities in parallel and eliminate unnecessary waste times as demonstrated on the next slide.
1. Activities Performed in serial
2. Activities performed in parallel
• If the performance of any system or process is not measured, it can not be meaningfully improved. Quantitative and qualitative measures that address both objective and subjective elements should be implemented.
• The measures recommended are Revenue per employee, percent defectives, cost of quality, profitability ratios, customer satisfaction index etc.

5. Mistake proofingMistake proofing
Mistake proofing
Mistake proofing is a scientific technique for improvement of operating system including materials, machines and methods with an aim of preventing problems due to human error. The term “error” means a sporadic deviation from standard procedures resulting from loss of memory, perception or motion.
Example : Bar codes and bar code readers prevents incorrect billing.
Defect Vs errors
It is important to understand that defects and errors are not the same thing. A defect is the result of an error, or an error is the cause of defects as explained below.

3. Benchmarking
Benchmarking is quality by comparison for achieving better standards. In the global movement today, the competition is increasing at a faster rate, and the only way to improve your relative quality and move upwards is to find out and implement the best industry practices.
Benchmarking
Benchmarking processes :-
Stages of improvement
World ClassRecognized as the best. Benchmarked by others even in other sectors
Best in ClassExceeds customer expectations,outperformsall competitors and has clear competitive edge
EfficientMeets all internal requirements for cost margins,asset utilization, cycle-time and measures of excellence
IncapableIs ineffective, inefficient and at the risk of failing.Needs major redesign
EffectiveSatisfies all customer requirements
Benchmarking methodology
Benchmarking can be of various types - Competitive benchmarking, product benchmarking, process benchmarking and best practices benchmarking. Whatever be the category chosen by the organization, the benchmarking methodology remains the same in each case. Benchmarking methodology is explained through 5 simple steps in the following slides.
a. Identify processes to benchmark
• Select processes to benchmark.• Measure current process capability.• Understand detailed process which needs improvement.
b. Select organization to benchmark
• Select organizations which perform your process. • Compile a list of world class process parameters.
c. Compile the required information
• Develop a detailed questionnaire to obtain desired information.
• Obtain the desired information. The information can be obtained from various sources viz: Internet, trade journals, professional associations, benchmarking centers, Industry publications, Industry experts, libraries etc.
d. Analyze gaps
Too much information is as bad as too little. Gather and analyze only the information you need to make a direct comparison of performance. Compare like with like - Compare apples with apples and pears with pears. Identify the performance gaps and develop an action plan to close the gaps. Also highlight and quantify the consequences of not closing the gap.
e. Develop an action plan
• Review observations of the gap analysis.• Set new performance standards.• Develop an action plan for meeting the new
performance standards.

4. PDCA
Plan-Do-Check-Act ( PDCA Cycle ):- A four step process for quality improvement.
• In the first step (PLAN), A plan to effect improvement is developed.
• In the Second step (DO), the plan is carried out.
• In the third step ( CHECK), the effects of the plan are observed.
• In the last step (ACT) ,Action is taken to carry out the plan after making necessary corrections.
This is repeated till the original plan is achieved.
PDCA ( Plan-Do-Check-Act )
The PDCA cycle has the advantage of being cyclical - implying that improvement never ceases.
Continuous process
Application of PDCA Cycle
The ultimate aim of any management system is continual improvement of its performance. To achieve this, Deming’s PDCA cycle of improvement is interwoven in the structure of the new standard.
