Study Notes

  • PERT uses network diagrams.
  • The project magic triangle includes time, cost, and scope.
  • The Critical Chain method is based on the Theory of Constraints.
  • Changing task work contour is effective for resolving resource conflicts.
  • Independent slack in the CPM method can be negative, positive or zero.
  • Student's syndrome relates closely to procrastination within the Critical Chain method.
  • Network graphs are finite, continuous, directed, acyclic with one beginning and one end node
  • Schedule Variance (SV) is a parameter of the earned value analysis.
  • A project buffer in Critical Chain is a time reserve to compensate for possible project delays.
  • The BCWS parameter is 300 000 CZK.
  • For the GERT model, if node number 2 is inclusively stochastic, all activities ending there are finished
  • The activity duration in PERT is calculated using pessimistic, optimistic, and most likely duration estimates
  • AON allows you to model various types of links between tasks compared to AOA.
  • If SPI < 1, the Project is behind schedule.
  • GERT allows loops and conditional branches, while PERT does not.
  • The best graphical tool for timeline display is a Gantt Chart
  • If an AON graph a(AB)=4, b(BA)=-5, then B must start no earlier than 5 units after A ends.
  • A resource buffer compensates for resource delays in CCPM.
  • In stochastic simulation, task duration is a random variable
  • Determining task dependencies is part of the Metra Potential Method
  • Waterfall methodology has limited ability to respond to changes in dynamic environments
  • While resolving resource conflicts, an effective method is to change the task work contour.
  • If AON a(AB)=6, b(BA)=-5, B >= 5 units after A ends.
  • Student's syndrome is closely related to procrastination.
