subtasks within each milestone, overall project assessment, problems encountered and recommended solutions. The reports shall detail the planned and actual progress during the period covered, ex plaining occurrences of any differences between the
two and the corrective steps. 
3.      The reports shall also include a three-month rolling forecast of the key planned
activities, referencing the WBS/IMS. 
4.      A tracking log of progress on regulatory submissions with the FDA number,
description of submission, date of submission, status of submission and next steps. 
5.      Provide updated EVM/CPR.
 6.      Estimated
and Actual Expenses. 
7.      This report shall also contain a narrative or table detailing whether there is a
significant discrepancy (>10%) at this time between the % of work completed and the cumulative costs incurred to date. Monthly and actual expenses should be broken down to the appropriate WBS level. This section of the report should also contain
estimates for the Subcontractors expenses from the previous month if the Subcontractor did not submit a bill in the previous month. If the subcontractor(s) was not working or did not incur any costs in the previous month, then a statement to
this effect should be included in this report for those respective subcontractors. |  |
