Notes

1. During the first four phases, the cycle (circulate, individual review, review meeting, updates/changes to document) could be repeated more than once. You should state in your estimates how many iterations of this cycle you are assuming .

2. Research could be a significant project in its own right requiring much further detailed breakdown.
