Introduction Lets take a few moments to set expectations:How many Agile practitioners?How many Lean Six Sigma, BPM or operationsmanagement practitioners?Has anyone previously combined Lean or Six Sigmaprocess improvement techniques with Agile?Are there any particular problems which you hopewill be addressed in this discussion?(c) 2001, C.C. Pace Systemswww.ccpace.com Combining Lean, Six Sigma and Agile: Why, and How? Page 5 6. What are Lean Six Sigma and Agile?Define Define Lean Six Sigma is one of a number of business process improvementMeasureMeasure methodologies, which shares rootsAnalyzeAnalyze with approaches such as BPM, TQM, SPC and others. Improve Improve (Process Focused)ControlControlAgile is an iterative and incremental approach to project delivery, encompassing methodologies such as Scrum and eXtreme Programming (XP). (Project Focused)(c) 2001, C.C. Pace Systemswww.ccpace.com Combining Lean, Six Sigma and Agile: Why, and How? Page 6 7. Basic Concepts of Lean Six Sigma A 5 step approach founded on asking the right questions: 1. Define: What is important to the customer? What is their target and acceptable limitations; anything else is considered defective 2. Measure: What is the frequency of defects? How many defects? Capability: How is the process performing for the customers? Entitlement: How good can the existing process be? Gage R&R: How good is the data? Is it reliable? 3. Analyze: Why, when and where do the defects occur? Data driven analysis to prove what the root causes are 4. Improve: How can we fix the process/critical defects? How can root causes can be addressed? 5. Control: How can we ensure the process remains fixed? Develop controls to ensure process improvement is sustained(c) 2001, C.C.

Basic Concepts of AgileKey Agile principles are: Focus on customer value Employ business-driven prioritization of features.Iterative & Incremental Delivery Create a flow of value to customers by chunkingfeature delivery into small increments.Intense Collaboration Face-to-facecommunication via collocation, etc;diversified roles on integratedteams.Self Organization Team members self-organize to fulfill a shared projectvision.Continuous Improvement Teams reflect, learn and adapt to change; work informs the plan.(c) 2001, C.C.

Demonstrated Successes Agile & Lean Six Sigma have both proven their mettle in the respective domains: Agile Project Execution: Improved time-to-market, collaboration and customer satisfactionLean Six Sigma Process Improvement: Better process controls, higher efficiency and effectiveness However, they still tend to operate independently.(c) 2001, C.C. Pace Systemswww.ccpace.com Combining Lean, Six Sigma and Agile: Why, and How? Page 9 10. II. The Case for Change (Why?)(c) 2001, C.C. Pace Systems www.ccpace.com Combining Lean, Six Sigma and Agile: Why, and How? Page 10 11. Why Do We Do Projects? Why do we do projects? a) Deliver to Initial Specifications b) Deliver on Time c) Deliver on Budget(Trick Question)(Trick Question) d) Increase Revenue e) Avoid Costs f) Improve Service g) Everything but a To enhance businesses profitability by:Providing Value to external Customers (better service,more revenue generated), andProviding Value to internal Customers (better service,lower cost) (c) 2001, C.C. Pace Systems www.ccpace.com Combining Lean, Six Sigma and Agile: Why, and How? Page 11 12. What is Value? Value is generated by addressing Customers most critical and pressing needs.Value, as defined by the Business Customer (Agile) Customer requirements (PMI) Voice of the Customer/Business, Critical to Quality requirements (Six Sigma) Value, Right Product/Time/Price (Lean) Related, but subtly different perspectives.(c) 2001, C.C. Pace Systems www.ccpace.com Combining Lean, Six Sigma and Agile: Why, and How? Page 12 13. Value from Two PerspectivesHow can we improve our capability to deliver Value through projects?Project Execution Improvements: Delivery speed While these areWhile these are criticallycritically Code qualityimportantimportant Business customer satisfactionBusiness-Focused Improvements: Impact on business process performance (cycle time, SLA fulfillment, audit These are more These are more compliance)often neglected...often neglected... And even more And even more Measurable contribution to strategic important. important. initiatives Incremental operational integration & deployment End user satisfaction (c) 2001, C.C. Pace Systemswww.ccpace.com Combining Lean, Six Sigma and Agile: Why, and How? Page 13 14. Repercussions of Independence Some common issues include: At the portfolio level:Arbitrary and inconsistent project selection criteriaPoor alignment of projects across value streamsUnfocused approach to risk management Within Agile projects:No quantification of project valueCustomer difficulty in providing grounded requirementsInconsistent alignment with highest-priority process needs Within Lean Six Sigma projects:No incremental delivery of business valueLimited scope of analysis and opportunity for measurementInsufficient linkage to execution of improvement recommendations(c) 2001, C.C. Pace Systemswww.ccpace.comCombining Lean, Six Sigma and Agile: Why, and How? Page 14 15. The Big Picture An explicit linkage from Customer to Process to Execution is necessary to ensure that the organization is tightly aligned with the real, changing needs of its users. (c) 2001, C.C. Pace Systemswww.ccpace.com Combining Lean, Six Sigma and Agile: Why, and How? Page 15 16. Problem Definition vs. Solution ExecutionLean and Six Sigma, by defining the problem, help to: Define and quantify Value Identify root causes of business problems Avoid suboptimization by providing full business context Align business management with true customer needsDo the right projects. Agile, by crafting the solution, helps to: Deliver incremental Value Provide framework for ongoing measurement of results Ensure effective implementation of improvements Align business management with implementation teamsDo the right projects right.(c) 2001, C.C. Pace Systems www.ccpace.com Combining Lean, Six Sigma and Agile: Why, and How? Page 16 17. Agiles Contributions Agile execution of Lean Six Sigma process improvementrecommendations can yield: Flexibility & SpeedDirect, continuously updated linkage to true needs of business & customersAbility to handle change beyond initial process analyses Minimized RiskIterative developmentIncremental delivery Better SolutionsFocus and refinement of recommended improvements at the implementationlevelIdeal platform for innovation and new product introduction More Versatile TeamsSupport for whole-of-life product maintenance and continuing developmentClose coordination between Business and IT(c) 2001, C.C.
