Hi,
Just thought to add my 2 bits to this discussion
I'm currently prep'ing to do the PMP first week of Oct 09 and hence am attempting to provide my perspective...
Say, i want to build a car and 10 people in the room decide that it's a good idea and we begin.
Discussion1. How will the car look and drive and what features will it provide the end-user who will buy and use the car, what will we name it, will it be petrol/diesel/water/air driven
etc etc...
Discussion2. With details from the first meeting, we begin to elaborate on features and details of stage 2. (This is progressive elaboration at work
"As per PMBOOK pg-7, Progressive elaboration involves continuously improving and detailing a plan as more detailed and specific information and more accurate estimates become available."
"Rolling wave planning" is basically to do with the whole "project management plan" depending on various information becoming available over the entire project management life-cycle.....
"As per PMBOK, Pg-46, Significant changes occurring throughout the project life-cycle triggers a need to revisit one or more of the planning processes and, possibly, some of the initiating processes. This progressive detailing of the project management plan is often called "rolling wave planning" indicating that planning and documentation are iterative and ongoing processes.
As per PMBOK, pg - 448, Scope creep: Adding features and functionality (project scope) without addressing the effects on time, cost and resources, or without customer approval. It is similar to "gold plating".
This would be like a team member who is part of this project team adding a GPRS and remote controlled PSP on the dashboard of the car so that the driver can play interactive games while twiddling his fingers on a traffic snarl
...... These features we're however not discussed with the client and we're just implemented by the team since they felt that these features would be highly desired on the product....
i hope the above explanation makes sense, request the experts to please correct me if i have made any mistake.
It will also help me clear concepts which i may have missed.
Cheers
Debu
