  1. Dumpster Diving – Finding Waste in IT

  2. Why it matters • Higher expectations • Lower Budgets • Growing Backlog • Expanding IT inventory to Support

  3. Lean Thinking in a nutshell • Maximize customer value while minimizing “WASTE”.

  4. Principles of Lean • Value • Value Stream • Flow • Pull • Perfection

  5. Value Stream Map (VSM)

  6. Principles of Lean • Value • Value Stream • Flow • Pull • Perfection

  7. Waste

  8. Where does it come from? You Burn , I’ll Scrape

  9. What is waste in software development? • D: Defects/Rework • O: Overproduction • W: Waiting • N: Non Standard – Over Processing • T: Transportation • I: Intellect - Underutilized Human Potential • M: Motion • E: Excess Inventory

  10. Defects/Rework • Application bugs • Poka Yoke • Missed requirements • Testing late in SDLC (ATDD)

  11. What is waste in software development? • D: Defects • O: Overproduction • W: Waiting • N: Non Standard – Over Processing • T: Transportation • I: Intellect - Underutilized Human Potential • M: Motion • E: Excess Inventory

  12. Overproduction • Bloatware • Committing too early • Extra copies • CYA • Maximize the amount of work NOT done

  13. What is waste in software development? • D: Defects • O: Overproduction • W: Waiting • N: Non Standard – Over Processing • T: Transportation • I: Intellect - Underutilized Human Potential • M: Motion • E: Excess Inventory

  14. Waiting • Batches of work • Bottlenecks • Waiting for review / approvals • Slow response time • Time between development and testing • Overnight processing of data

  15. What is waste in software development? • D: Defects • O: Overproduction • W: Waiting • N: Non Standard – Over Processing • T: Transportation • I: Intellect - Underutilized Human Potential • M: Motion • E: Excess Inventory

  16. Over - processing • Gold Plating • Complexity that could be simplified • Tracking data that’s not used • Automating flexibility that will never be used

  17. What is waste in software development? • D: Defects • O: Overproduction • W: Waiting • N: Non Standard – Over Processing • T: Transportation • I: Intellect - Underutilized Human Potential • M: Motion • E: Excess Inventory

  18. Transportation • Filing physical documents that could be stored electronically • Unnecessary movement of electronic data • Entering data from one system to another • Under use of video conferencing

  19. What is waste in software development? • D: Defects • O: Overproduction • W: Waiting • N: Non Standard – Over Processing • T: Transportation • I: Intellect - Underutilized Human Potential • M: Motion • E: Excess Inventory

  20. Underutilized Human Potential • Un-empowered employees • Dull, repetitive tasks that could be automated • Not capturing and sharing ideas • Not investing in training and education • No time for professional improvement

  21. What is waste in software development? • D: Defects • O: Overproduction • W: Waiting • N: Non Standard – Over Processing • T: Transportation • I: Intellect - Underutilized Human Potential • M: Motion • E: Excess Inventory

  22. Motion • UX not streamlined to workflow • Scrolling on a page • Toggling between disconnected systems • Unnecessary key strokes or mouse clicks

  23. What is waste in software development? • D: Defects • O: Overproduction • W: Waiting • N: Non Standard – Over Processing • T: Transportation • I: Intellect - Underutilized Human Potential • M: Motion • E: Excess Inventory

  24. Excess Inventory • Stockpile of Requirements • Data collected and not used • Work waiting to be reviewed or approved • Backlog items that will never be worked • Partially completed work
