The duration of each work package (WP) and the interdependencies between the WPs are used for process and time scheduling [16].

Step 1
Place the WPs in sequence and link the individual WPs.

Step 2
Has any WP been forgotten? If necessary, define the missing WPs and include them (in the WBS and, after costing, in the cost breakdown structure and process schedule).

Step 3
Include the WP duration in the process schedule.

Step 4
Make forward and backward pass calculations.

Step 5
Calculate free float and determine the critical path.

Step 6
Schedule the WP.

Step 7
Identify any problems and resolve them (e.g. by adapting resources or objectives at deadline and/ or quality level).

Procedures after preparing the process and time schedules
Now it's time to prepare the risk analysis.
