Lean Thinking

Hi Folks

In my last post, I mentioned in passing the phenomenon of sub-optimization - where optimizing one part of a process negatively affects the throughput of the whole. This is covered by the seventh (and probably least understood) principle of Lean - See The Whole.

Hi Folks

In many companies, resource utilization is considered an important measurement. The idea is that resources, whether they be machines or people should be occupied as close to 100% of the time as possible doing chargeable work. On the surface this looks pretty sensible. No point having people spending time doing things that the company doesn't make money from is there? The more time people spend working on chargeable tasks, the more money the company makes. Right?

Hi Folks

I had a discussion recently with a group of software architects about whether Architecture had a place in Agile development. This is an important (and at times hotly debated) topic so I'm going to expand on the discussion here.

In Lean, waste is anything that does not add value. The key to Lean is getting work flowing rapidly and this is done by identifying and eliminating sources of waste. Some sources of waste are obvious - tasks blocked through lack of feedback, rework due to misunderstood requirements and things like that. Some sources of waste though are not so obvious. Some are so insidious that we live with them all the time and assume they are an inevitable part of daily life.
