Since forever, Project Managers and business owners have been using a variety of approaches to manage projects adequately. In the beginning, it’s fair to assume that most of said techniques were manual and then, later computerized.
These two techniques are called Program Evaluation and Review Techniques (PERT) and Critical Path Management (CPM). These two are close techniques will regularly be refered to as CPM/PERT.
In order to identify the task, the technique uses network models to trace the links between tasks which are very important in order to meet the deadlines. When you have a big amount of tasks stacking up, you always must use the correct tool for the job, to show which tasks can be pushed back, and which ones can be on time.
After you’ve established the critical path, any set back on that part of the path will cause a delay in the entire project. This is where Project Managers have to show their skills.
With MS Project, you can use Tracking Gantt to display the critical path in red and you can see the PERT diagram by viewing the “Network” view.
Ultimately, you want to follow the amount of completion of each of the tasks. This could be done daily. When something begins to go wrong, you can just adjust correspondingly.
Without going into details of how to renumerate for delays and what not, read up more on the subject.
