SMSVN – PMP Training Course 2013 – Chapter 6 Prepared by Nam Trung - 16/07/2013 DEPENDENCY DETERMINATION To define sequence among activity, these type of dependency are used:  Mandatory (hard logic)  Inherent in the nature of work being done or required by the contract  E.g. You must design before you can develop  Discretionary (preferred, preferential, or soft logic)  Define base on knowledge of best practices  Can be changed if needed  Important when how to shorten or re-sequence the project  External  Based on the need of the party outside the project 6
  7. 7. SMSVN – PMP Training Course 2013 – Chapter 6 Prepared by Nam Trung - 16/07/2013 LEAD AND LAGS  Leads and Lags are used to support realistic and achievable project schedule.  Each activity is connected at least to one predecessor and one successor except the start and the end.  Leads:  May be added to start an activity before the predecessor activity is complete.  can be used only on finish-to-start activity relationships.  Lags:  is a delay in the successor activity  can be found on all activity relationship types. 7 A B C predecessor Successor

Schedule management plan .Activity list .Activity attributes .Resource calendars .Risk register .Activity cost estimates .EEF .OPA .Expert Judment .Alternative analysis .Published estimating data .Bottom up estimating .Project management software .Activity resources requirements .Resource breakdown structure .Project document updates
  10. 10. SMSVN – PMP Training Course 2013 – Chapter 6 Prepared by Nam Trung - 16/07/2013 6.5 ESTIMATE ACTIVITY DURATIONS  Is the process of estimating the number of work periods to complete individual activities with estimated resources.  The key benefit is providing the amount of time each activity will take to complete. 10 Inputs Tool&Techniques Outputs . Schedule management plan .Activity list .Activity attributes .Activity resources requirements .Resource calendars .Project scope statement .Risk register .Resource breakdown structure .EEF .OPA .Expert Judment .Analogous estimating .Parametric estimating .Three-point estimating .Group decision-making techniques .Reserve analysis .Activity duration estimates .Project document updates
  11. 11. SMSVN – PMP Training Course 2013 – Chapter 6 Prepared by Nam Trung - 16/07/2013 ESTIMATE ACTIVITY DURATIONS (TOOLS & TECHNIQUES)  Analogous Estimating (Top down):  estimates using historical data from a similar activity or project  less costly, less time -> less accurate  Parametric Estimating:  estimates using a statistical relationship between historical data and other variables -> higher accuracy  3-points Estimating:  Also called Program Evaluation and Review technique (PERT)  Use for time and cost estimation  Expected calculated from Most-likely, Optimistic, Pessimistic  Expected = (P + 4M + O)/6  Standard Deviation = (P - O)/6  Group decision-making techniques: brainstorming…  Reserve analysis (buffer): includes contingency reserves 11
  12. 12.
