“Descriptive Project Title”
Customer Profile – 28,000 Retail Business Process Capability – Before Business Problem & Impact Average speed to answer (ASA) was 1 minute. As call volumes increased 30% with a recent acquisition, end user downtime was costing the company US$500K annually. The target average speed to answer was under 30 seconds. Measure & Analyze Data Collection: Speed to answer on all calls was measured. The existing process sigma was 2.4. Root Causes: Nature of problem and time of call were identified as root causes. Process Capability – After Improve & Control Cross-training on call types was performed and staffing was arranged around peak call times. Metrics are reviewed weekly and posted to an IT dashboard. Project Completion Date: 06/2010 Project Owner Name & Phone: Sandy Jones, Black Belt Name & Phone: Joe Smith, Results/Benefits After the 3 month project, the customer saved US$150K, or 30%, as a result of reduced end user downtime. A Savings of US $150k in 2011 International Standards for Lean Six Sigma

Analyze Overview Hypothesis Tests Value-Add Analysis Root Cause / Effect Tools Used Root cause: Effect Data Analysis What potential KPIVs were identified? Show the key statistical and graphical tools which narrowed the potential KPIVs. Show regression models developed. How good is the model? Show ANOVA results. Show Hypothesis Test results. What have you learned? Do you see any important interactions between various parameters? Were there any special causes in the data? What did you do? Standard Deviation What effect would a lot of variation in the population have on our estimate of the population mean from a sample? How would this affect our ability to draw conclusions about the mean? What if there is very little variation in the population? Statistical Inferences and Confidence How much confidence do we have in our estimates? How close do you think the true mean, m, is to our estimate of the mean, x-bar? How certain do we want/need to be about conclusions we make from our estimates? If we want to be more confident about our sample estimate (i.e., we want a lower risk of being wrong), then we must relax our statement of how close we are to the true value. Three Factors drive Sample Sizes Three concepts affect the conclusions drawn from a single sample data set of (n) items: Variation in the underlying population (sigma) Risk of drawing the wrong conclusions (alpha, beta) How small a Difference is significant (delta) These 3 factors work together. Each affects the others. Variation: When there’s greater variation, a larger sample is needed to have the same level of confidence that the test will be valid. More variation diminishes our confidence level. Risk: If we want to be more confident that we are not going to make a decision error or miss a significant event, we must increase the sample size. Difference: If we want to be confident that we can identify a smaller difference between two test samples, the sample size must increase Process Balancing “Process Balancing” is a procedure whereby a set of process steps are “equalized” in terms of time required to accomplish them (note “effort” may not be the same!). Process balancing tools are used where the process is contained in a defined area. Examples include: Order Entry Department Mortgage Application Process Key tools used in process balancing are the time study and takt time chart, but other tools such as skill matrix, etc., may play a significant role in the analysis. The Process Balancing techniques are not exclusive to “one-piece flow” – small batches may be necessary between certain steps – but use of the process balancing tools is meant to drive the process to one-piece flow. Primary Issues in Typical Transactional Environments Excess “stuff in process” Poor space utilization Low employee efficiency Long/erratic cycle times Poor balance of labor content across process steps Conveyance, standby and motion waste Disorganized workspace and component/supply storage High variability of demand on multiple processing centers – e.g., call centers/customer arrivals High variability of task content (non-standard work/procedures) Define: What is the Goal of balancing the process? Capacity improvement without adding resources Productivity improvement without sacrificing quality Space reduction Day-to-Day scheduling Long-term resource planning Measure: What tools will be used to gather, present, and analyze data? Time Study and Task Times (breakdown of NVA, BVA, CVA) Historical: Exits, Productivity, Customer Demand, Staffing, etc. Layout and spaghetti flow Analyze: Task Time Chart with breakdown of NVA, BVA, CVA Time Traps and Constraints (if any) Variability of Demand Improve: What steps will be taken and in what order? 1. Reduce NVA of Constraints and Time Traps to meet Customer Demand General Rule is that Max Task Time (incl. NVA+BVA+CVA) of Time Trap should be no more than 90% of Takt Time for low variability 2. Reduce NVA of non-Time Traps General Rule is that Max Task Time of all other non-Time Traps should no more than 90% of Takt Time (customer demand) for highly predictable environments OR 80% of Takt Time for processes with variability 3. Reorder/Re-sort tasks to balance work content, alter staffing 4. Modify Layout to accommodate new staffing Implement work controls (generic pull) 5. Iterate on reducing NVA, then BVA, then CVA and rebalancing/re-staffing until goals are achieved. Cost targets, capacity requirements, etc. Control: Implement visual control tools to sustain the improvements Takt Boards for the Time Trap and overall process 5S & Issue Boards for problem resolution and process control Customer Value Add: A task or activity for which the customer would be willing to pay. Example: Electronic funds transfer via credit card Business Value Add: A task that is required to support the business but for which the customer is not willing to pay Example: Financial Services employee writing customer credit history on a credit application Non-Value Add: A task that is not required and should be eliminated because it is wasteful Example: Financial Services employee having to look for missing information needed to complete credit history Review Sources of Waste Transportation (moving items from one place to another) Inventory (items/paperwork/information waiting to be processed) Motion (excess movement and/or poor ergonomics) Waiting (delays caused by shortages, approvals, downtime) Overprocessing (adding more value than the customer is paying for) Overproduction Defects (rework & scrap – doing the same job more than once) Another waste is: People (untapped and/or misused resources) Hypothesis Testing: Allows us to determine statistically whether or not a value is cause for alarm (or is simply due to random variation) Tells us whether or not two sets of data are different Tells us whether or not a statistical parameter (mean, standard deviation, etc.) is statistically different from a test value of interest Allows us to assess the “strength” of our conclusion (our probability of being correct or wrong) Hypothesis Testing Enables Us to: Handle uncertainty using a commonly accepted approach Be more objective (2 persons will use the same techniques and come to similar conclusions almost all of the time) Confirm or disprove assumptions Control our risk of making wrong decisions or coming to wrong conclusions The null hypothesis is a statement you are testing in order to determine whether or not that statement is true. We assume the null hypothesis is true unless we have enough evidence to prove otherwise. If we can prove otherwise, then we reject the null hypothesis. The alternative hypothesis is a statement that represents reality if there is enough evidence to reject Ho. If we reject the null hypothesis then we accept the alternative hypothesis. This is analogous to being found “guilty” in a court of law. Assumptions - The Hypothesis Tests we have discussed make certain assumptions: Independence between and within samples Random samples Normally distributed data Unknown Variance In our example, we did not assume equal variances. This is the safe choice. However, if we had reason to believe equal variances, then we could have checked the “Assume equal variances” box in the dialogue box. Type I Error - I’ve discovered something that really isn’t here! Alpha Risk Producer Risk The risk of rejecting the null, and taking action, when none was necessary Type II Error - I’ve missed a significant effect Beta Risk Consumer Risk The risk of accepting the null when you should have rejected it. No action is taken when there should have been action. The Type I Error is determined up front. It is the alpha value you choose. The confidence level is one minus the alpha level. The Type II Error is determined from the circumstances of the situation. If alpha is made very small, then beta increases (all else being equal). Requiring overwhelming evidence to reject the null increases the chances of a type II error. To minimize beta, while holding alpha constant, requires increased sample sizes. One minus beta is the probability of rejecting the null hypothesis when it is false. This is referred to as the Power of the test. The p-Value If we reject the null hypothesis, the p-value is the probability of being wrong. In other words, if we reject the null hypothesis, the p-value is the probability of making a Type I error. It is the critical alpha value at which the null hypothesis is rejected. If we don’t want alpha to be more than 0.05, then we simply reject the null hypothesis when the p-value is 0.05 or less. Beta, Power, and Sample Size If two populations truly have different means, but only by a very small amount, then you are more likely to conclude they are the same. This means that the beta risk is greater. Beta only comes into play if the null hypothesis truly is false. The “more” false it is, the greater your chances of detecting it, and the lower your beta risk. The power of a hypothesis test is its ability to detect an effect of a given magnitude. Minitab will calculate beta for us for a given sample size, but first let’s show it graphically…. We have concentrated on 2-sided hypothesis tests. 2-Sided tests determine whether or not two items are equal or whether a parameter is equal to some value. Whether an item is less than or greater than another item or a value is not sought up front. A 2-sided test is a less specific test. The alternative hypothesis is “Not Equal”. Everything we have learned also applies to 1-sided tests. 1-Sided tests determine whether or not an item is less than (<) or greater than (>) another item or value. The alternative hypothesis is either (<) or (>). This makes for a more powerful test (lower beta at a given alpha and sample size).

Solution Selection Criteria Pilot and Implementation Plan Choose solutions that will impact the root cause's) heavily, which will in turn reduce your problem. You do not want to implement a dozen solutions, each of which makes only a small difference in the bottom line. Note: Benefits realization will begin upon improvement implementation, unless approved by Financial Representatives Solution: What are the solutions for implementation? What solutions were considered in the Solution Selection Matrix? What were the criteria? What were the results of the Pugh matrix, if used? Has the process owner been involved in the review of recommended actions? What changes are recommended? What techniques were used to evaluate the risk of the chosen solutions? What changes were made? What efforts were made to optimize the solution and what were the results? What are the initial thoughts on a Control Plan? - Identify all opportunities for continuous improvement Reduction of effort Reduction of time Reduction of space Reduction of cost Reduction of mistakes Increasing customer satisfaction - Improve the process through a variety of Lean tools/techniques: Value Stream Mapping Time Trap Identification Heijunka/Leveling/Stability (S&OP) Kaizen/Continuous Improvement Kaikaku/Innovation Jidoka/Autonomation Kanban/Just In Time 5S Organization Stocking Strategy Generic & Replenishment Pull Systems MRP/Pull System integration Single Minute Exchange of Die (SMED) Visual Tools, Visual Processes Cellular Layouts & Line Balancing Standardized Work Total Productive Maintenance (TPM) Make vs Buy, Distribution Mgmt, Vert Integ Strategic Sourcing, Tactical Purchasing Faster feedback on process performance (increased learning cycles) Improved first pass yield (results in improved productivity) Improved process stability (results in improved throughput) Uncovers process deficiencies (forces problem resolution) Less in-process and buffer inventories (reduced risk) Improved customer satisfaction (flexibility and responsiveness) Check for the Ripple Effect and Unintended Consequences Even a small change in a business process can affect many other processes. During a pilot, the team may need to double-check for this “ripple” effect. Impact on Other Processes Make sure the new design has not somehow caused problems for your internal supplier and customer processes. People working in such support areas as planning, customer service, operations, and quality control need to know that you are doing things differently so they can adjust their work where necessary. Check administrative processes such as personnel, finance, or accounting. If one of your solutions, for example, is to cross-train people in several skills, the human resources department may need to revise job descriptions. The pilot plan should be designed to include steps to analyze the results. Root causes of performance gaps may need to be analyzed or redesigned. Summarizing Pilot Conclusions Once all the pilot data has been collected and the results verified, the team can determine the next steps toward solution implementation. Only after an objective and comprehensive assessment of the pilot can responsible “next step” decisions be made. Some questions a team should ask upon the completion of a pilot to help guide them toward identification of the proper next steps are: Did pilot have anticipated results? Was the plan for conducting the pilot effective? What improvements can we make to the solution? Can the solution be implemented “as-is”? Should it be? Can the solution remain in place at the pilot location? What lessons learned and best practices can we apply during solution implementation? Did the solution achieve the required design goals? Don’t skip the pilot! Define successful criteria before testing the pilot Agree on a list of critical parameters to continue Document all test results and control procedures Train all process participants How the solution was determined: What was the solution selection tool used? What project management tools were used? Cost/benefit analysis? Include any other tools or methods used ? Enter Key Slide Take Away (Key Point) Here International Standards for Lean Six Sigma

Business Impact State financial impact of future project leverage opportunities Separate “hard or Type 1” from “soft Type 2 or 3” dollars Annual Estimate Replicated Estimate Revenue Enhancement Type 1: ? Type 2: ? Type 3: ? Expenses Reduction Loss Reduction Cost Avoidance Total Savings Lean 6 Sigma Project Documentation General Guidance The project charter templates provided will document both the functional and financial goals to be realized. When the Project Charter portion of the project is documented sufficiently for a Black Belt to begin work, a copy of the documentation can be placed in the Project Hopper. When a Black Belt begins work on a particular project, that project’s Project Charter should be removed from the Project Hopper as it is no longer available to be worked. The financial portion of the Project Charter should initially be completed by the Project Sponsor and the Financial Representative to show projected savings. This portion should also be updated as the project progresses to clearly show true savings achieved. When the project is completed, the Financial Representative should validate that the project savings were achieved as recorded. The financial portion (now validated savings) should then be forwarded to Deployment Champion. ***************************************************************************************************** State financial impact of project Expenses Investments (inventory, capital, A/R) Budget Separate “hard” from “soft” dollars State financial impact of future project leverage opportunities Benefits – Will the project make a significant impact on the Business? Is the project driven by the Business strategy? What are the expected Business Benefits of the project? What are the critical assumptions in the benefit analysis? Does the Financial Manager endorse the Benefit calculation? Definitions Growth = Percentage Increase in Revenue Return on Invested Capital: If a shareholder invests a dollar, how much will be earned each year? Return = Profit After Tax (Net Operating Profit After Tax, NOPAT) Invested Capital = Working Capital + Plant, Property & Equip. (PP&E) Return on Invested Capital = Profit After Tax/Invested Capital Cost of Capital = How Much a Company Pays for Its Capital ~ 12% Compare the Cost of Capital to the Internal Rate of Return (IRR) of a project’s cash flows (more on this later) Finding the Financial Impact We must be able to satisfactorily demonstrate the impact of our improvement project activities Typically, there are at least four categories of impact: “Green” dollars positive dollars that exit or enter the organization, that appear on the profit and loss (P&L) statement (Measurable) Redeployment of resources – people or equipment no P&L impact, versus a baseline, but reduces cost needed to support business growth, realized immediately upon redeployment (Can be difficult to measure) Cost avoidance, reduces the need to add cost to support business growth, ex. capacity improvement. Realized when the business grows (Can be difficult to measure with certainty) Strategic. May be no “hard” financial impact, but the right thing to do in terms of the future of the business. (Very difficult to measure the true impact) Examples of Potential Revenue Enhancement: New sales of existing or new products Increased retention of profitable customers Examples of Potential Cost Reduction: Price increases Labor Cost – Reduced number of hand-offs Servicing Cost – Decreased number of quality related service calls Rework – Less defective work due to improving quality at the source of the defect Examples of Potential Capital Reduction Supplies – Decreased volume of inventory due to process improvements Cost of Capital – Decreased time of service to customer payment Occupancy – Decreased storage area due to quicker shipping times Direct Costs – These are costs that can be traced directly to providing a service. For example direct labor charges to include wage and benefit costs. Also, any cost associated with materials or service maintenance . One Time Costs – These are costs which are incurred only once. Examples include new equipment or facilities, initial training, initial software installation and configuration, etc. On-Going Costs – These are costs which will continuously be incurred. Examples included labor, on-going training, supplies and other operating costs. If you must prove the bottom line impact of a project, reduce the dollars that exit the organization or increase the Revenue entering the organization! Make sure that all stakeholders agree on the project’s impact and how it will be measured in financial terms! Regularly seek the advice and input of members of the financial community, especially on the assumptions to make and means of calculating the stream of financial benefits from an improvement project. Each project should have a financial rep (a person from outside the team) to assist and review financial benefits calculations. Economic Profit can be impacted in three ways: Revenue Growth Volume increases due to improved customer satisfaction, faster delivery, differentiated features, etc. Cost Reduction Purchase items and services Waste elimination Make vs. Buy Labor reduction Productivity improvements Scrap/Rework reductions Capital Reduction Inventory Accounts Receivables Assets While overall project benefits are frequently a combination of all three levels, it is important to understand the distinction. Lean Six Sigma Financial Principles Every step is taken to ensure the integrity and accuracy of the data. Processes developed to calculate and assess benefits must be simple and not overly complex. Benefits are measured using established financial, cost and investment methodologies/principles/practices/guidelines of the company as appropriate. Impacts on internal controls are proactively identified and communicated. The primary reporting metric for Lean Six Sigma projects is the impact on Economic Profit. All benefits and costs should be reported in $US dollars using the current year plan exchange rate. All organizations consistently define, quantify, measure and report Lean Six Sigma projects in the tracking system. Lean Six Sigma metrics complements, but does not replace, other critical business measures and analyses. Black Belt, Project Sponsor and Financial Representative need to form a partnership with the Financial Representative acting as a key consultant to the project team Roles and Responsibilities Black Belt/Project Sponsor Define current operational process and establish baseline with metrics and data Determine process improvement relative to baseline and metrics Define logic for benefits Determine type of benefits Calculate financial benefit outlook Support validation of benefits during realization Ensure benefits info is included in DMS by Measure tollgate Ensure Type 1 savings are tracked to BLI and customers are in agreement by Control Certifies savings Financial Representative Review and consult on expected benefit projections at Define phase Validate financial benefits before Control tollgate Validate actual project benefits during realization Expertise solicited only at critical points Available to advise Project Sponsor if needed during tollgate reviews Charter Benefits Review (before Launch): Financial Representative should be consulted with on the expected Benefits identified in the Project Charter Benefits Realization Schedule Review (before Implementation) Financial Representative validates the Tracking Methodology and Benefit Realization Schedule (the monthly Benefit projection) prior to implementation. Financial representatives review and consult on expected benefit projections at Define phase. BBs, ensure benefits info is included in Measure. This will be added to the measure tollgate checklist. FR Validate financial benefits before Control tollgate. Black/Green Belt Certification Review (after 2 months of realization) Financial Representative reviews the Benefits calculations made to-date by the Process Owner. PS ensure actual project benefits are identified during realization. FR Validate actual project benefits during realization.

What steps were taken to ensure the integrity & accuracy of the data? Has the project tracking worksheet been updated? ************************************************************************** Validating financial benefit projections is one of the most important, but challenging, tasks to perform in validating the Project Charter Often the financial benefit projections written in the “Business Impact” section of the Project Charter are notional “rough order of magnitude (ROM)” or “back of the envelope” estimates without much analytical rigor applied in the calculations The “Future Reality Tree” is a tool we can use to analyze and document the “chain of causality” from the operationally-oriented “Goal Statement” to the financial dollar savings/benefits stated in the “Business Impact” section of the Project Charter The Future Reality Tree is a graphical approach to map out the cause–effect relationships which form the basis of the change you intend to make. It shows in clear, cause–effect relationships, how the proposed change should create the desired result, surfacing potential side effects along the way. In Lean Six Sigma, we use it to: Define the thinking behind our proposed project Confirm the logic of the project Assess the valuation of the project Surface risk issues *************************************************************************************************** Identify the basic improvements desired from the proposed project (intended to produce the desired result). Avoid identifying specific solutions; rather identify the nature of the improvement desired. Make sure that the cause–effect relationship is clear and self-evident. Avoid making “trans-Atlantic leaps” but rather take “baby steps”. If you find yourself thinking of effects that stretch far from the causes, insert intermediate steps Review with one or more knowledgeable associates to ensure clarity, correctness and completeness. Strive for clarity, correctness and completeness Use non-offensive wording Build shared understanding Make sure you are satisfied that the solutions really will produce the desired results (and the financial impact!) Welcome negative branches, then deal with them When objections are raised, try to determine the specific logic that is being challenged. ************************************************************************************ Valid Objections Clarity – I don’t understand what you mean Entity Existence – I don’t believe that “A” happens Cause Existence – I don’t believe that “A” causes “B” Additional Effect – But “A” also causes “D” Cause Insufficiency – But “A” won’t cause “B” unless “C” happens too Additional Cause – But “B” is also caused by “E” Circular Reasoning – How can “A” cause “B” if “B” causes “A” Comptrollers Role Provide input regarding project viability from a financial perspective What type of savings are expected? What effort will be required to capture them? Will investment be required? Review actual project savings claims as project approaches completion Are the savings numbers accurate? Can we capture them in a meaningful way? Audit actual results in the ‘Sustain’ stage Have the actual savings been realized? If no, what is the recovery plan? Types of Benefits Type I: Hard savings that can be readily identified in budget terms and can be used for recapitalization Type II: Resources that are freed up to move to value-added work TYPE III: Intangible benefits Type I benefits have a clear impact on the NAVSUP budget. The relationship between the project and the benefits are direct. Type I benefits result in an adjustment to the business plan and are permanent. Examples of Type I Benefits: Reduction in labor costs and billets Non-labor reductions (I.e., NMCI seats, supplies) Space reductions that result in termination of a lease Scrap or material reductions Contract cost reductions Type I reductions must be a primary goal in order for NAVSUP to deal with solvency concerns and accomplish required efficiencies Booking Manpower Savings Manpower savings will be booked in the fiscal year in which the savings are actually realized The booking of manpower savings must begin no later than the fiscal year after project completion Projects must focus on current savings; deferring manpower savings into the future defeats the purpose of Lean 6 Sigma Type II benefits do not have an immediate impact on available funds. Type II benefits are assets or resources that are freed up and may be re-utilized on value-added work. Type II benefits may result in future savings Examples of Type II Benefits: Floor space is reduced, but building is not vacated Allows reallocation of the space Future resource requirements are reduced in existing budget documentation Type III benefits are mainly intangible and cannot be captured in the budget or other documentation. Examples of Type III Benefits: Customer Satisfaction increases An expenditure that was not budgeted is avoided Employees are more satisfied Response time is improved ********************************************************************* Projects requiring investments No project requiring investment will be approved unless: Type I and II project savings will exceed investment cost within 1 year Projects that produce savings without requiring investment are preferred Enter Key Slide Take Away (Key Point) Here International Standards for Lean Six Sigma

Lessons Learned ? Every improvement effort offers a lesson. It is what we do with these lessons that matters. For successful projects, we want to document our efforts and conclusions to repeat the success. If not successful, we want to document what went wrong to prevent repeating the same mistakes. The availability of this type of information can greatly accelerate future efforts. Enter Key Slide Take Away (Key Point) Here International Standards for Lean Six Sigma
