You’re going to use predecessors in your project schedule rather than entering start and finish dates for each task. Building a schedule with predecessors is called dynamic scheduling because you use the software to do the work of keeping the schedule current. For example, you’ll tell the software that task B can’t start until task A is finished – task A is the predecessor of task B. There are other predecessor relationships but that’s a common example. The software will use it to schedule and calculate the duration of every task. This dynamic schedule also allows you to easily model options and alternative ways of doing the project. Clients really like having models of options so they can make decisions about the project.
What Happens If I Don’t Control The Sequencing Of My Tasks Correctly?
If you don’t use predecessor relationships and dynamic scheduling, you’ll waste many hours updating your schedule every week trying to keep track of what’s going on. You also don’t have a tool for modeling corrective action or providing the client sponsor with options. Project managers who built their schedules by entering start and finish dates usually find they can’t keep up with the maintenance. After a while, they stop trying to update the schedule to show what’s actually happening on the project. Clients really don’t like that.
