itSMF - Foundations of Lean IT


Published on

This is a presentation I gave to the Ohio Valley LIG of the Service Management Forum in April of 2010.

I focused the presentation on three main themes:
1) The refinement or removal of non value-added processes in IT (the "big" idea of Lean IT)
2) The institution of metrics (if you don't know where you are now, how do you know where you're going in the future?)
3) The enhancement of communications (manage projects throughout their lifecycle using normalized interfaces)

itSMF - Foundations of Lean IT

  1. 1. Presented by Matt Blair MSISA, Dir. of Prof. Development Indiana University
  2. 2. Agenda 1 Overview of Lean IT • Impacts many internal and external customers of the IT value-stream. • Cuts back the waste of outgrown information technology 2 Benefits of Lean IT • Allows delivery of a more efficient, higher-quality product. • Promotes companies’ CMMI, pushing for more efficient approaches. 3 Example of Implementing Lean IT • Integrates IT resources more evenly within a company. • Refines corporate governance to formalize processes. 4 Next Steps • Take Advantage of a widely-accepted, repeatable process. LEAN IT • Reference additional resources for deeper research. Overview Benefits Example Next Steps

  4. 4. Lean IT Cuts Back the Waste of Outgrown Information Technology Overproduction / Rework Wasted Motion Overprocessing • Early fulfillment of requests • Changes in business requirements • Unprioritized task processing • Unnecessary functionality • Application bugs, errors • Unplanned task switching Wasted Inventory Wasted Time Wasted Intellect • Maintenance backlogs • Key resources aren’t available • Limited cross-training • Partially completed requests • Idle developers • Poor usage of resources Non-Value Added Motion / Repeat Processing Problems LEAN IT • Anchoring to out-of-date processes • Ignoring foundational errors • Unnecessary documentation • Trading off for short-term gains Overview Benefits Example Next Steps
  5. 5. Lean IT allows you to Deliver a More Efficient, Higher Quality Product TIME-TO-MARKET PRODUCT QUALITY COST of RESOURCES  Efficient processes lead  Decreased errors  More effective use of to faster turnaround. provides a higher quality resources leads to  Increased agility makes it product, increasing brand increased availability. easier to respond to market reputation.  Less paperwork leads to needs.  Straightforward process less working hours and  Competitive edge helps design eases lesser staffing needs. companies stay ahead of manufacturing woes. competition. By enhancing the repeatability of IT processes, organizations can leverage added efficiencies for more effective resources to generate a higher quality output.

  6. 6. Organizations and Processes with Low CMMI’s can Experience the Most Benefits Lean initiatives can • Organizational innovation & deployment advance organizations Optimized • Causal analysis and resolution with lower maturities to refine processes and progress their maturity. Quantitatively • Highly repeatable processes Managed • Performance measurement, benchmarking • Process standardization Defined • Infrastructure integration • Focus on process enhancement Process integration through the • Agreements and vendor contracts use of standardized interfaces Managed • Project planning, requirements management increases cross-division interaction. Lean documentation makes LEAN IT • Unpredictable processes maintenance more direct, Initial • Reactive support, poorly controlled allowing more time to be spent on prescriptive development.

  7. 7. Application Maintenance and Development is a High-Risk Area of the IT Value-Chain The Relative Cost of Correcting Errors found in Different Development Stages 80x -- 80x Relative Cost to Fix Defect The frequency of errors can be minimized through requirement confirmation, The cost of correcting an -- 60x (multiplier) iteration and passing error increases as a product procedural gates. progresses through the application development -- 40x lifecycle. By focusing on the 15x -- 20x foundations of requirements, errors can be 2x 8x addressed before they are 0x designed, tested and deployed prior to being confirmed.
