The remaining 3 points from my earlier post on the first principle of lean software development are:
- Over Processing
- Over Production
- Defects and Rework
Over production in a production environment, means producing more stock than the consumer will consume or at a rate that leads to a build up of inventory. In a software situation I consider the features to be analogous to the product. If you are producing features that are not needed by the customer then you are over producing. In a software sense this is very similar to the over-processing.
Defects and Rework, in my experience, are where a large chunk of waste in a traditional software development lie. I seem to spend a lot of time fixing bugs. So what do we do about it? Test Driven Design, Continuous Integration and "Stop the Line" are some of the tools advocated by Lean software. I guess I'll have to write about some of them in another post.
As I said this was going to be a short one. I'll move on to the next of the principles tomorrow...
