The
start date for the project is 12 October. All Saturdays and Sundays are
non-working days. Calculate the Saturdays and Sundays on the basis of
the current calendar year. Additionally, the following are non-working
days:
- 30 November
- 25 December
- 28 December
- 1 January
- 4 January
- 17 March
- 2 April
- 5 April

At
the close of the client feedback session (task 8), the head of the
sales department wants some changes to be made, and as such, makes a
formal change request that day. It takes 14 working days for the change
request to be approved.
An analysis of the impact of the change reveals the following:
- Changes to the database module will require 5 days.
- Testing of the new database module will take 5 days following the changes.
- Changes to the support modules will require 7 additional days of work.
- Changes to the high-level functions will require 10 additional days of work.
