|Change of Plan vs. new SOW|
It there a quantifiable method that can be used to determine if the size of a requested change would merit writing a new Statement of Work instead of writing a Change of Plan?
My Example -- We just completed installing a new network topology for an entire building. The architectural diagrams were all approved by the client before beginning execution. Now that the network is in and we're heading towards project closure, the client stated that they believe the topology is too complex and wants a redesign. My opinion is that this would be a new project, or at least a "Phase 2" with a new SOW, not just a Change of Plan.
What are your thoughts, and do you have guidance for a methodology that can be used to make the determination?
