Project Schedule Management Flashcards
Schedule Processes
Planning: Plan Schedule Management Define Activities Sequence Activities Estimate Activity Durations Develop Schedule Monitoring/Controlling: Control Schedule
Plan Schedule Management
I: Project charter, PM plan, EEFs, OPAs
TT: Expert judgment, data analysis, meetings
O: Schedule management plan
Define Activities
I: PM plan, EEFs, OPAs
TT: Expert judgment, decomposition, rolling wave planning, meetings
O: Activity list, activity attributes, milestone list, change requests, PM plan updates
Sequence Activities
I: PM plan, project documents, EEFs, OPAs
TT: Precedence diagramming method, Dependency determination and integration, Leads and lags, PM information system
O: Project schedule network diagrams, project documents updates
Estimate Activity Durations
I: PM plan, project documents, EEFs, OPAs
TT: Expert judgment, analogous estimating, parametric estimating, three-point estimating (most likely, optimistic, pessimistic), bottom-up estimating, data analysis, decision making, meetings
O: Duration estimates, basis of estimates, project documents updates
Develop Schedule
I: PM plan, project documents, agreements, EEFs, OPAs
TT: Schedule network analysis, Critical path method, Resource optimization, data analysis, leads/lags, schedule compression, PM information system, agile release planning
O: Schedule baseline, project schedule (Gantt chart), schedule data, project calendars, change requests, PM plan updates, project documents updates
Control Schedule
I: PM plan, project documents, work performance data, OPAs
TT: Data analysis, Critical path method, PM information system, Resource optimization, Leads/lags, schedule compression
O: Work performance information, schedule forecasts, change requests, PM plan updates, project documents updates
Precedence relationships
Lags / Leads
Finish to Start
Finish to Finish
Start to Start
Start to Finish
Lag: successor starts later than predecessor finish (eg, FS+10 means activity 2 cannot start until 10 days after activity 1 ends
Lead: successor starts before predecessor finish (eg, FS-10 means activity 2 can begin up to 10 days before activity 1 finishes)
Critical Path Method
Early Start, Duration, Early Finish
Late Start, Total Float, Late Finish
Forward Pass:
ES=1; EF=ES+duration-1
ES=EF of predecessor +1 (if two predecessors, use latest EF)
Backward Pass:
EF = LF for last activity; LS = LF-duration +1
LF = LS of successor - 1 (if two successors, use the smallest one)
Float = LF-EF or LS-ES
Float = 0: activity must occur as planned or risk running late
Critical Path = all activities with 0 float, min amount of time for project
Resource Optimization
Resource leveling: balancing demand for resources with available supply (eg, ensuring only 8 hrs per day), may delay past critical path
Resource smoothing: activities only delayed within available float (sticks to critical path)
Schedule compression
Crashing: Adding resources (approving overtime, new people) -> increased cost to stay on schedule
Fast tracking: phases usually in sequence performed in parallel -> increased risk
Schedule outputs
WBS (output of Create WBS), leads to Activity List (through decomp, output of Define Activities), leads to Network Diagram (precedence diagramming, output of Sequence Activities), leads to Schedule baseline (includes duration estimates, Critical Path Method, output of Develop Schedule)
