Sab8#65:_Method_Control_Schedule_Project

1. Modeling

   • what-if analysis.
     • Trying to think through all of the possible problems your project could run into
     • That way, you can figure out how to deal with any problems that might come your way.
   • Simulation
     • This is a specific kind of what-if analysis where you model uncertainty using a computer
       • Calculate risk using random numbers and Monte Carlo analysis algorithms
       • While this is not a commonly used technique, there might be a question or two about it on the PMP exam, and you should know what it is.
   • Scheduling tool
     • Using a project management software package to create a model of the schedule and adjusting various elements to see what might happen

2. Critical Path

   • The critical path is the string of activities that will delay the whole project if any one of them is delayed.
     • A delay in any one of the critical path activities will cause the entire project to be delayed.
     • It’s the string of activities that, if you add up all of the durations, is longer than any other path through the network.
   • This can really help you handle emergency situations. Even better, it means that if you need to bring your project in earlier, you know that adding resources to the critical path will be much more effective than adding them elsewhere.
   • How to find it?
     • 1. Start with an activity network diagram
     • 2. Find all of the paths in the diagram
     • 3. Find the duration of each path
     • 4. The critical path is the one with the longest duration

3. Resource Optimization

   • Sometimes only one resource can do a given activity. If that resource is busy doing another activity on the critical path, the path itself needs to change to include that dependency.
     • That’s the point of resource leveling. It evaluates all of the resources to see if the critical path needs to change to accommodate resource assignments.

4. Schedule compression

   • Crash the schedule
     • When you absolutely have to meet the date and you are running behind, you can sometimes find ways to do activities more quickly by adding more resources to critical path tasks.
       • Crashing the schedule means adding resources or moving them around to shorten it. Crashing ALWAYS costs more and doesn’t always work!
       • if the budget is fixed and you don’t have any extra money to spend, you can’t use this technique.
   • Fast-Tracking
     • You’ve got two activities planned to occur in sequence, but you can actually do them at the same time
       • There’s a good chance you will need to redo some of the work you have done concurrently.
       • This is pretty risky,
       • On the exam, if you see something about “overlapping activities,” it’s talking about fast-tracking.

5. Critical Chain Method

   • 1. Resource dependencies are used to determine the critical path.
   • 2. Add buffers
   • 3. Working backward from the delivery date into the schedule at strategic points
   • 4. Managing the project so that each milestone is hit on time
