Combination of the two is successful when agile techniques are leveraged to drive towards the desired architecture.
In lean manufacturing, the definition of inventory is pretty clear. It is the extra material, work in progress material and material queued up for the next bit of work. Lean emphasizes on reducing the inventory because there is always an inventory handling costs. In software development, often requirements are seen as inventory, what about the code?
