Tips on using this forum..

(1) Explain your problem, don't simply post "This isn't working". What were you doing when you faced the problem? What have you tried to resolve - did you look for a solution using "Search" ? Has it happened just once or several times?

(2) It's also good to get feedback when a solution is found, return to the original post to explain how it was resolved so that more people can also use the results.

Has any PPer got a good and simple definition of the rolling wave method?

Rob’s hit the nail on the head.

I’ve used the technique extensively on projects where customer mandated the use of EVM. On one of the projects we were even paid by EV.

There’s a useful book on EV by Joel Koppelman (of Primavera fame) and Quentin Fleming. IIRC correctly it addresses the technique in relation to EV but there’s nothing difficult about it.

Regards

Gary,

Rolling Wave Planning is the conversion of Planning Packages (PP) into Work Packages(WP)during the different phases of a project. Rather than defining and baselining the complete scope of work in detail, the short term work is planned in detail and the far term scope is baselined at a higher (summary)level (Planning Package) thereby providing more flexibility.
Rolling Wave Planning is common to projects using Earned Value Methodology. I’ve successfully used this technique on several large projects by applying a window (3 months after time now)to future activities in the project schedule to identify these PPs. The PPs would then be defined into more detail or depending on float maybe replanned to occur later.
But a key to this process is to provide traceability by logging the changes and reasons.

Cheers,
Rob.

A quick search through Google turned up a couple of slides from the Max Wideman site:

It looks like it is the same thing as Spiral Planning. Basically, a project is broken down into small mini-projects and each phase is planned and executed iteratively. Ie. the second phase is not planned until the first phase is complete.
