You have been asked to determine a rough schedule for a nine month billing system conversion project, as part of your job as a consultant to a Fortune $500$ firm. The firm's old system was written in COBOL on a mainframe computer, and the maintenance costs are prohibitive. The new system will run on an off$-$the$-$shelf application. You have identified several high$-$level activities that must be done in order to initiate, plan, execute, control, and close the project. The table below shows your analysis of the project's tasks and schedule so far.
