todolist # 13 Decompose the work packages into activities

In todolist#12 we discussed about the work breakdown structure. The next step is to decompose the work packages (the lowest level in the WBS) to activities. Once the work packages are decomposed into activities, it is advisable to do a bottom up estimation (so far the estimations were done top down). One we do a bottom up estimation, by and large the sum of the effort of the activities should tally with the work package estimates. If there is a big gap, that is a clear indication of error in estimates (either in the top down or in the bottom up).
