  3. Project Charter Problem:Describe problem in non-technical terms • Statement should explain why project is important; why working on it is a priority Goal: Goals communicate “before” and “after” conditions • Shift mean, variance, or both? • Should impact cost, time, quality dimensions • Express goals using SMART criteria • Specific, Measurable, Attainable, Resource Requirements, Time Boundaries • Explain leverage and strategic implications (if any) Problem/Goal Statement Financial Impact • State financial impact of project • Expenses • Investments (inventory, capital, A/R) • Revenues • Separate “hard” from “soft” dollars • State financial impact of leverage opportunities (future projects) Team Tollgate Review Schedule • PES Name Project Executive Sponsor (if different from PS) • PS Name Project Sponsor/Process Owner • DC Name Deployment Champion • GB/BB Name Green Belt/Black Belt • MBB Name Master Black Belt • Core Team Role % Contrib.

  4. Data Collection Plan • For each performance measure (Y), update a data collection plan • Include MSA measure plan (Gantt chart, MS project plan is Optional) • Add Financial measure plan if separate from performance Y • Add any Time Study or other data collection plans for Value Stream Map • Sample Size Calculation • Use additional slides if needed Enter Key Slide Take Away (Key Point) Here International Standards for Lean Six Sigma

  5. Operational Definitions • Y – Continuous data (Process start/stop and cycle time boundaries (such as the unit of measure (ex minutes), the unit (the thing you are measuring), will you include weekends, holidays, non-business hours?) • Y – Discrete data (Define Success/Defect or other attribute values you will measure • X – The subgroups values or X-factor groupings you will use on your project data collection • Other unique terms that apply to your project that require clear operational definitions • Use additional slides as needed to complete your operational definitions Enter Key Slide Take Away (Key Point) Here International Standards for Lean Six Sigma

  6. MSA Conclusions • The measurement systems are acceptable. The data is considered to have no potential for significant error. Need to be careful to appropriately use the data during the Analyze Phase. Enter Key Slide Take Away (Key Point) Here International Standards for Lean Six Sigma

  7. Baseline Basic Statistics • The current process has a non-normal distribution with the P-Value < 0.05 but does have a normal bell-shape. • Since the mean and median are the same in days (29) +/- 0.5 days, we will not transform data. • The range is 35 and the standard deviation is 2.7 days Enter Key Slide Take Away (Key Point) Here International Standards for Lean Six Sigma

  8. Baseline Process Capability • 266 data points collected between 11/1/04 thru 11/30/04 • Mean 29 days, St. Dev. 2.9 days, CP is 1.16 indicating process needs centering to the LSL of 10 and USL of 30 days. Cpk is .1 indicating that the process is exceeding the USL. • With an overall PPM of 371,895 defects per million opportunity, the current process has a Sigma Quality Level of 1.8 or a 62% yield Enter Key Slide Take Away (Key Point) Here International Standards for Lean Six Sigma

  21. MeasureTollgate Checklist Stop Tollgate Review • Has a more detailed Value Stream Map been completed to better understand the process and problem, and where in the process the root causes might reside? • Has the team conducted a value-added and cycle time analysis, identifying areas where time and resources are devoted to tasks not critical to the customer? • Has the team identified the specific input (x), process (x), and output (y) measures needing to be collected for both effectiveness and efficiency categories (i.e. Quality, Speed, and Cost measures)? • Has the team developed clear, unambiguous operational definitions for each measurement and tested them with others to ensure clarity/consistent interpretation? • Has a clear, reasonable choice been made between gathering new data or taking advantage of existing data already collected by the organization? • Has an appropriate sample size and sampling frequency been established to ensure valid representation of the process we’re measuring? • Has the measurement system been checked for repeatability and reproducibility, potentially including training of data collectors? • Has the team developed and tested data collection forms or check sheets which are easy to use and provide consistent, complete data? • Has baseline performance and process capability been established? How large is the gap between current performance and the customer (or project) requirements? • Has the team been able to identify any complete ‘Quick Wins’? • Have any Kaizen opportunities been identified to accelerate momentum and results? • Have key learning(s) to-date required any modification of the Project Charter? If so, have these changes been approved by the Project Sponsor and the Key Stakeholders? • Have any new risks to project success been identified, added to the Risk Mitigation Plan, and a mitigation strategy put in place?

  22. AnalyzeTollgate Checklist Stop Tollgate Review • Has the team examined the process and identified potential bottlenecks, disconnects and redundancies that could contribute to the problem statement? • Has the team analyzed data about the process and its performance to help stratify the problem, understand reasons for variation in the process, and generate hypothesis as to the root causes of the current process performance? • Has an evaluation been done to determine whether the problem can be solved without a fundamental recreation of the process? Has the decision been confirmed with the Project Sponsor? • Has the team investigated and validated (or devalidated) the root cause hypotheses generated earlier, to gain confidence that the “vital few” root causes have been uncovered? • Does the team understand why the problem (the Quality, Cycle Time or Cost Efficiency issue identified in the Problem Statement) is being seen? • Has the team been able to identify any additional ‘Quick Wins’? • Have learningsto-date required modification of the Project Charter? If so, have these changes been approved by the Project Sponsor and the Key Stakeholders? • Have any new risks to project success been identified, added to the Risk Mitigation Plan, and a mitigation strategy put in place? Deliverables: • List of Potential Root causes • Prioritized List of Validated Root Causes • Additional “Quick Wins”, if applicable • Refined Charter, as necessary • Updated Risk Mitigation Plan • Deliverables Uploaded to Central Storage Location or Deployment Management System Has the team identified the key factors (critical X’s) that have the biggest impact on process performance? Have they validated the root causes? International Standards for Lean Six Sigma 22
