Tasks 2 (AC4.2)
The following schedule is taken from a similar production project:
Activity                         Predecessor       Duration (weeks)
A. Plan prototype                   -                            4
B. Make prototype                A                            21
C. Issue Specification             A                            8
D. Prepare tests                      C                            10
E. Publicity Material                C                         30
F. Production                         BD                         36
G. Prepare sales                   BD                            3
H. Sales orders                      EG                            9
I. Delivery                               FH                            3
a. Construct a network diagram from the information given in the table above.
b. Find the critical path and state it's duration
c. Using the information gained from the critical path, create a project plan enabling schedules to be controlled using a Gantt chart.

Tasks 3 (D2)
If the duration of 'B' (make prototype) in Task 2 is increased by four weeks, estimate the effect on the Critical Path and determine the new duration of the project.
Propose a possible solution to correct any delay and identify which activities may be amenable to change.
NB. Appropriate software applications may be utilised in the calculation of project durations, critical paths and the production of Gannt charts.
