  • 3. UNCLASSIFIED / FOUO Learning Objectives Apply the concepts of Control Plans to process improvement projects i t j t Apply the concepts of Standard Operating Procedures to process improvement processes 3 Process Control UNCLASSIFIED / FOUO
  • 4. UNCLASSIFIED / FOUO Control Phase Tasks After developing and implementing a pilot: 1. Validate the measurement system for the KPOV(s) and critical KPIV(s) We discussed these tools earlier 2. Implement the improvements 3. Create a process control system to make sure that the improved process stays in control Document th appropriate procedures f monitoring th process, D t the i t d for it i the including how to react if it goes out of control Development of the process control system really gets started early in your p j y project but is implemented in the Control Phase p 4. Process Documentation and Standard Operating Procedures 5. Project closure and commissioning We will discuss this tool later 4 Process Control UNCLASSIFIED / FOUO
  • 5. UNCLASSIFIED / FOUO Measurement System Analysis When collecting data as part of our control system, we must verify th t th t if that there i not excessive is t i measurement system variation present. This really should have been done prior to conducting h ll h ld h b d d significant analysis but now is your absolute last chance To validate the measurement system, you should use the same process that you learned in the MSA modules in Measure 5 Process Control UNCLASSIFIED / FOUO
  • 6. UNCLASSIFIED / FOUO Determine Process Capability Process capability is the measure for how a process is performing Verify that our process is doing better, we need to re- calculate that number now Recalculate during the pilot phase to confirm the capability has improved, then calculate it again after the improvement has gone live in the workplace The second "real-world" calculation should only happen after enough time has passed to allow sufficient sampling and the process is in control For the purpose of this training, that means after you have completed the Control tasks 6 Process Control UNCLASSIFIED / FOUO
  • 7. UNCLASSIFIED / FOUO Improvement Confirmation Confirmation in Six Sigma means statistics that will back b k up your decisions. d i i We will be using calculations that you have already learned in process capability and hypothesis testing l d bl dh h This means comparing the mean and standard deviation of the original data collected with data collected after the improvement 7 Process Control UNCLASSIFIED / FOUO

  • 9. UNCLASSIFIED / FOUO Cultural Issues and Control If data has been used to develop the solution, if it fails, it is usually not due to technical issues Acceptance by the people in the process (cultural issues) often determines success or failure Force Field Analysis helps to identify and mitigate cultural risk Driving forces are things that can or will drive the organization to implement the change Restraining forces are things that can or will drive the organization to reject the change Key: Strengthen driving forces and/or weaken restraining forces 9 Process Control UNCLASSIFIED / FOUO
  • 10. UNCLASSIFIED / FOUO Exercise: Cultural Issues For your training project, complete a Force Field analysis for the implementation and control plans __________________ Project Implementation and Control Driving Forces Restraining Forces 10 Process Control UNCLASSIFIED / FOUO
  • 11. UNCLASSIFIED / FOUO Maintaining the Improvement There are the three approaches you can use to maintain your process improvement. i t i i t They are not sequential, however there is somewhat of a h f hierarchy: h Risk Management Mistake P Mi t k Proofing fi Both should be considered before or in tandem with a control charting strategy, because they are strategies for avoiding potential problems altogether Control Charts can only monitor for potential problems All th ee app oaches must have three approaches m st ha e Control Plans to sustain the gains 11 Process Control UNCLASSIFIED / FOUO
  • 12. UNCLASSIFIED / FOUO Mistake Proofing The best approach to process control is Mistake Proofing. Proofing Mistake Proofing is a method for avoiding errors in a process The simplest definition of "Mistake Proofing” is that it Mistake Proofing is a technique for eliminating errors by making it impossible to make mistakes in the process Unfortunately, mistake proofing is not always possible or economically practical, therefore you must develop a plan with on-going monitoring 12 Process Control UNCLASSIFIED / FOUO
  • 13. UNCLASSIFIED / FOUO Control Charts Control charts are essentially a feedback system Generating control charts requires on-going data collection on a process to monitor how it performed before and after the improvements b f d f h 13 Process Control UNCLASSIFIED / FOUO
  • 14. UNCLASSIFIED / FOUO Review of Control Charts Focuses attention on measuring and tracking g g process variation over time Distinguishes between special and common g p causes of variation Used as a tool for process control ( p (can monitor inputs and outputs over time) Tracks process improvements in q p p quality, cost y, and/or throughput Establishes a normative and uniform language g g for comparing performance among processes 14 UNCLASSIFIED / FOUO
  • 15. UNCLASSIFIED / FOUO Steps to Create Control Charts Determine where to use control charts Determine the control chart type, and then the sampling method Collect data Calculate statistics Track data, remove causes for out-of-control points, and recalculate statistics. Repeat until stable. Develop action plan for out-of-control conditions Run the process over time 15 UNCLASSIFIED / FOUO

  • 20. UNCLASSIFIED / FOUO Watch for Patterns OUTLIERS Wrong process settings, error in measurement, subgrouping or plotting, incomplete operation, machine and tool breakdowns, power surge. SHIFTS Is the change sudden or gradual? Introduction of a new material, machine, operator, inspector or test set, new process controls, maintenance, process changes, change in proportion of materials from different sources. TRENDS Tool or fixture wear, deterioration of materials, aging, changes in maintenance or calibration, environmental factors human factors, calibration factors, factors production schedules, gradual changes in materials or process, accumulation of waste products, machine warm-up. 20 UNCLASSIFIED / FOUO
  • 21. UNCLASSIFIED / FOUO Watch for Patterns CYCLES Does the time period of the cycle suggest a cause? Environmental factors, worn locations on tools or fixtures, human factors, gage changes, voltage fluctuations, shift changes, systematic rotation of equipment or materials, merging of subassemblies or processes. STRATIFICATION Could each subgroup be a mixture of data from more than one source? Non-random sampling, miscalculation, i N d li i l l ti incorrect chart t t h t type, non-rational ti l subgrouping, reduction in process variability, changes in inspection process. MIXTURES Could subgroups be coming from two sources alternately? Two or more different materials, operators, designs, or testers mixed in the process, over adjustments of the process, poor sampling procedures, control of two or more processes on the same chart 21 UNCLASSIFIED / FOUO
  • 22. UNCLASSIFIED / FOUO Implementation Notes Use Control Charts where it will be of benefit Design the improvements and monitor their impact over time Train everyone on how to read control charts Create a control plan to identify “triggers” to watch triggers and “responses” to implement Beware: Graphs can be misleading 22 UNCLASSIFIED / FOUO
  • 23. UNCLASSIFIED / FOUO What Is a Control Plan? Control plans provide a written summary description of the systems used i minimizing process and service variation t d in i i i i d i i ti Control plans do not replace information contained in detailed instructions In a grand sense the control plan describes the actions that are required at each phase of the process including receiving, in-process, outgoing, and periodic requirements to assure that all process outputs will be in a state of control Ultimately, the control plan is a living document reflecting current methods of control and measurement systems used 23 Process Control UNCLASSIFIED / FOUO
  • 24. UNCLASSIFIED / FOUO Control Plan Minimum Requirements 1. Identify the process that is being controlled 2. Identify measures (numbers) to be monitored 3. Identify “trigger point” values for each measure where trigger point action should be taken 4. 4 Identify action to be taken when a “trigger point” is trigger point reached 5. 5 Identify who is responsible for taking action when a “trigger point” is reached 24 Process Control UNCLASSIFIED / FOUO
  • 25. UNCLASSIFIED / FOUO Elements of Process Control Plans Holds the performance gains made Assists in highlighting opportunities for further improvement activities Is a living document Adjusted as conditions change and further improvements made Has formal provision for periodic review Is interesting and easy to understand – use pictures and colors 25 Process Control UNCLASSIFIED / FOUO
  • 26. UNCLASSIFIED / FOUO Why Is a Process Control Plan Necessary? Processes have a tendency to degrade over time Also, at this stage, the process is generally moving beyond the hands of the CPI team Those who are responsible for continuing the process need a clear understanding of how to implement it consistently and steps to take if it gets out of control The improved process needs to be communicated to all involved parties through documentation and p g training A data collection plan is also necessary to test the improved process and confirm that the solutions are i d d fi h h l i indeed having positive impact 26 Process Control UNCLASSIFIED / FOUO
  • 27. UNCLASSIFIED / FOUO Existing Control Documentation Many processes already have in place what are called "quality plans" to ensure each service characteristic or sub- " lit l "t h i h t i ti b process stays in conformance with their overall process You should take into consideration any existing quality plans as part of establishing a process control system for your project The existing plan may include process procedures and tolerances, as well as items to be monitored for control and response plans in the event of a process breakdown. These p p p can inform your own control plan Your improved sub-process may have an impact on the quality plan, so you need to include changes to it as part of plan your documentation 27 Process Control UNCLASSIFIED / FOUO
  • 28. UNCLASSIFIED / FOUO Process Control Plan Header Control Plan Number (for Doc. Control) Date revised and effective date Contact person who “owns” Control Plan owns Team personnel that created Plan Service or Product numbers/processes that Plan applies to Other identification notes 28 Process Control UNCLASSIFIED / FOUO

  • 31. UNCLASSIFIED / FOUO Control Plan Strategy The intent of an effective control plan strategy is to: Operate our processes consistently on target with minimum variation Minimize process tampering (over-adjustment) (over adjustment) Assure that the process improvements that have been identified and implemented become institutionalized p Provide for adequate training in all procedures Include required maintenance schedules Revise Perodically 31 Process Control UNCLASSIFIED / FOUO

  • 41. UNCLASSIFIED / FOUO Examples of Reaction Plans Adjust the machine and recheck Separate service and quarantine Return to supplier / previous process step Notify supervisor Resource shift NOTE: Area personnel will typically have a list of items to check when a characteristic wanders out of control 41 Process Control UNCLASSIFIED / FOUO
  • 42. UNCLASSIFIED / FOUO Reaction Types Compensate This type of control involves making a process adjustment to bring the variable back into control without identifying or correcting the factor aches which caused the situation oved Correct Approa Impro In this type of control action, the cause of the variation is identified and corrected temporarily. The problem may reappear soon. Prevent A In this type of action, the cause of the variation is identified and permanently corrected. The cause will not happen again or at least will not occur as often. Typically, unsuccessful control programs utilize only compensating actions. Focus control plan response on preventative action. Examples include i l d root cause analysis, personnel training, preventative t l i lt i i t ti maintenance, controller tuning and replacing defective equipment. 42 Process Control UNCLASSIFIED / FOUO
  • 43. UNCLASSIFIED / FOUO How to Take Preventative Action When an undocumented out-of-control condition occurs, a cross- functional team consisting mainly of area personnel process personnel, engineers, and supervisors identify the variable to be controlled and follow these steps: 1. Prepare or update a process flow diagram of the system 2. A cause/effect (fishbone) diagram is prepared illustrating possible causes of variation in the process Four basic areas to center on are: manpower, materials, methods, and machinery 3. 3 The team selects the most likely causes from the list 4. Starting with the most likely causes, root causes of the variation are identified. Ask “WHY?” five times! Find root causes, not likely causes! 43 Process Control UNCLASSIFIED / FOUO
  • 44. UNCLASSIFIED / FOUO How to Take Preventative Action (Cont.) 5. Prepare a Reaction Plan for each out-of-control condition Causes are placed in the order that they should be checked, the most likely C l d i th d th t th h ld b h k d th t lik l or easiest to check first The team determines compensating actions to take should no cause be identified 6. The Reaction Plan is reviewed by the team and the process experts for modifications. The team determines how the plan will be documented and how to train the work force 7. Corrective action (permanent ones!) assignments are made and followed up to prevent recurrence! 8. Define a plan to collect data on how often the reaction plan is used and how well it works. Review results quarterly q y 44 Process Control UNCLASSIFIED / FOUO
  • 45. UNCLASSIFIED / FOUO Trouble Shooting A control plan is a logical, systematic approach for finding d fi di and correcting root causes of out-of-control ti t f t f t l conditions, and will be a valuable tool for process improvement A key advantage of the reaction plan form is its use as a troubleshooting guide for area personnel A systematic guide of what to look for during upset conditions is valuable on its own 45 Process Control UNCLASSIFIED / FOUO

  • 97. UNCLASSIFIED / FOUO Control Chart tips p Binomial data needs to be reported and charted with sample size. Example: Number of rejects out of number shipped Items cannot be compared to each other by merely looking at bar graphs of averages (bar graph = bad; control chart = good). To measure process improvement, look at impact on the process in total (total number of defects, total cost, etc.). Some process changes merely move defect type or cost into another form. Measure and chart the “actual thing”! To measure process improvement, Avoid ratios and other computed values such as “average cost per employee”. What matters is impact on total actual cost. Avoid charting deviation from nominal forecast budget etc nominal, forecast, budget, etc. 97 UNCLASSIFIED / FOUO
