  • 1. Don’t Improve Work, Remove Waste
    By Paul Brink, February 2010
  • 2. 2 : 2 : ½
    Increasing quality andspeeding up IT projectsis a major challenge
    Large IT projects often suffer from the 2:2:½-syndrome
    • The project takes twice as long
    • 3. The project costs twice as much
    • 4. The project delivers half of the functionality

  • 5. Desperately looking for solutions
    Organizations are desperately looking for solutions to speed up their IT projects and increasing the quality of their output
    Many solutions have been tried like:
    Improving project and quality management systems(e.g. Prince2, MSP and CMMi)
    Introducing new development methods(e.g. RAD and Extreme Programming)
    Implementing new development tooling(e.g. advanced IDE’s and BPM/BRE-tooling)
    Introducing new technologies(e.g. an ESB to enable a Service Oriented Architecture)
  • 6. But look no further…
    There is a much better way
  • 7. Lean your IT process
  • 8. Definitions of time
    Lead Time = Cycle Time + Waiting Time
    Lead time = the time it takes to complete a process - from start to finish
    Cycle time = the time a product is being worked on
    Waiting time = the time spent waiting around to be worked on
  • 9. Improve waiting time, not cycle time
    80 to 90% of the lead time of administrative processes consists of waiting time.
    Focusing on improving waiting time is much more beneficial, than focusing on speeding up the actual work (cycle time).
    A way to reduce the lead time is to eliminate “waste”. Waste is any activity that consumes time, resources, or space but does not add any value to the product or service.
    Therefore…Don’t improve Work,
    Remove Waste
  • 10. Muda, Muri and Mura無駄 無理 ムラ
    While the elimination of waste may seem like a simple and clear subject it is noticeable that waste is often very conservatively identified. There are three broad types of waste:
    Muda, 無駄is a traditional general Japanese term for an activity that is wasteful and doesn't add value, is unproductive or un-useful in practice
    Muri, 無理is a Japanese term for overburden, unreasonable or absurdity
    Mura, 斑 or ムラis a traditional general Japanese term for unevenness, inconsistency in physical matter or human spiritual condition
  • 11. 無駄
    Muda – Remove all types of waste
    Muda identifies seven original types of waste. Many others have added the “waste of unused human talent” to the original seven wastes. The goal is to eliminate these wastes.
    Transportation
    Inventory
    Motion
    Waiting
    Overproduction
    Over Processing
    Defects
    • Moving products that is not actually required to perform the processing
    • 12. All components, work in process and finished product not being processed
    • 13. People or equipment moving or walking more than is required to perform the processing
    • 14. Waiting for the next production step
    • 15. Production ahead of demand
    • 16. Resulting from poor tool or product design creating activity
    • 17. The effort involved in inspecting for and fixing defects
  • 無理
    Muri – Improve work, but don’t push it
    Muri is all the unreasonable work that management imposes on workers and machines because of poor organization, such as carrying heavy weights, moving things around, dangerous tasks, even working significantly faster than usual.
    It is pushing a person or a machine beyond its natural limits. This may simply be asking a greater level of performance from a process than it can handle without taking shortcuts and informally modifying decision criteria.
    Unreasonable work is almost always a cause of multiple variations in time and quality. So don’t push it. It won’t work.
  • 18. ムラ
    Mura – Merge sub-processes into one
    Mura can be eliminated by production leveling. It is possible to smooth the workflow by having one person work across several process steps rather than have different persons working on one process step; in a sense merging several sub-processes under one person.
    The fact that there is one person, will force a smoothness across the operations because the work piece “flows” with the person.
    This is called “multi-process handling”.
  • 19. The way to go…
    To increase the quality and lead time of IT projects one should focus on waiting time, not on cycle time.
    New methods, new tooling and new technology will improve cycle time, but much more is to be gained when focused on waiting time.
    The elimination of waste is essential to improve the quality and lead time of IT projects:
    Muda – Remove all types of waste
    Muri – Improve work, but don’t push it
    Mura – Merge sub-processes into one
