Lean Software Development Overview
We’ve had “lean healthcare day” before, maybe today is “lean software day.” A recent visitor to this blog is a software developer and pointed me to some resources on applying lean methods and principles to software development.
I’m not a software expert, although I have been involved in software projects. It always frustrated me that software development for lean manufacturing applications (in both the auto industry and PC manufacturing) used PUSH software methodologies.
The push software approach had many of the hallmarks of push production:
1) Throwing the design over the wall, with little contact between the customer and production (coding)
2) The whole development process was scheduled out ala MRP, assuming that all lead times were predictable and achievable
3) Quality control was focused on inspection rather than building in quality at the source.
The linked article here talks about 7 principles of “Lean Software Development”. They don’t map perfectly to the 7 Forms of Waste or even the 5 Lean Thinking principles, but it’s an interesting list and application of lean.
