For those familiar with Earned Value, we know that the calculations require a baseline (which get created at the end of the planning phase), as well as actual costs.
But what about all that time spent during the all-important initiation phase (which should include some sort of conceptual planning and alternatives analysis) and the planning phase (which includes WBS and schedule development)? These happen prior to Earned Value tracking.
Typically, there will be quite a bit of time spent in these phases, and by the time the baseline is approved at the end of these phases, a big chunk of the budget has already been spent. Since we can't use Earned Value during those phases (no baseline exists yet), how can we avoid blowing our budget too early?
I've seen several approaches to this:
1) One approach is to create the initiate phase in the project schedule immediately upon starting a project. Begin tracking time immediately. Consider starting with a baseline (i.e. budget) for that phase, and tracking against "budget" just like you would the rest of the project. The problem is that it's hard to budget for this type of activity.
2) Another approach is to do the initiation work (conceptual planning, initial requirements gathering, preliminary scope and business case development, etc.) outside of the project, and begin the project with the charter resulting from that "early initiation" activity (typically just after project approval). As Max Wideman said on his site, there's not really consensus in the industry if these "front-loading" activities should be part of the project or not. Still, you'd need track the WBS and schedule development, but at least those activities are easier to get a handle on.
3) I've even seen companies not bother tracking time until the schedule has been created and baselined. All initiation and planning phases are outside of the project. Sometimes they don't even submit their project for acceptance until after the WBS and schedule have been created. Most companies want the first approval earlier, though, based on an order-of-magnitude estimate.
I'd be curious to see what other approaches may exist for controlling (or not) the time spent on the initiation and planning phases.
