What are the ramifications of moving from a project orientation to a process or product orientation? First, an organization needs to establish an efficient means of production. It must create a funding model and a value stream equipped and staffed with people able to deliver its software requirements. Then the organization must manage the flow of work into that development value stream. The concept of flow is critical to value stream performance. Lean manufacturing principles have established that an overloaded value stream slows down the rate of delivery, increases costs, and decreases quality.
