Develop Schedule Process
Develop Schedule Process: is the core of Time management knowledge area. It is the process where you put all thing together, what you have done so far and putting it up all together and combining it onto one and come up with final schedule of the whole project.
Develop Schedule brings everything you’ve done so far together into one final schedule. All of the outputs from the other Time Management processes are inputs to Develop Schedule.
The critical path method is an important tool for keeping your projects on track. Every network diagram has something called the critical path. It’s the string of activities that, if you add up all of the durations, is longer than any other path through the network. It usually starts with the first activity in the network and usually ends with the last one. The reason that the critical path is, well, critical, is that every single activity on the path must finish on time in order for the project to come in on time. A delay in any one of the critical path activities will cause the entire project to be delayed.
One of the most useful things you can do is calculate the float. The float for any activity is the amount of time that it can slip before it causes your
project to be delayed. You might also see the word slack—it’s the same thing.
The float for every activity in the critical path is zero.
For example Let say we have activities and its duration :
A:3 ,B:1, C:7,D:4,E:3,F:2,G:2
Let say we have three paths Are:
Start → A → B → C → Finish = 11
Start → D → E → Finish = 7
Start → D → F→ G → Finish = 8.
Find the next longest path. Subtract its duration from the duration of the critical path, and that’s the float for each activity on it.
The duration for this path is 8, and for the critical path it’s 11. So the float is 11 – 8 = 3. So the D,F,G has the float 3.
Do the same for the next longest path, and so on through the rest of the network diagram. Pretty soon, you’ll fill in the float for every activity!
The duration for this path is 7, and for the critical path it’s 11. So the float is 11 – 7 = 4. So E has float 4, We have already calculated D previously.
