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)
But look no further… There is a much better way
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
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
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
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
All components, work in process and finished product not being processed
People or equipment moving or walking more than is required to perform the processing
Resulting from poor tool or product design creating activity
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.
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”.
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
