6 5 Develop Schedule The process of analysing

6. 5 Develop Schedule • The process of analysing activity sequences, durations, resource requirements and schedule constraints to create the project schedule • All this data is entered into a project scheduling tool which generates a schedule with planned dates for completing project activities • An iterative process with several cycles of refinement • Baseline Schedule developed in Planning Phase • Simultaneous with 6. 1, 6. 2, 6. 3 & 6. 4 Monitor Initiation Planning Execution Close Control Adapted from PMBOK 4 th Edition BSBPMG 503 A Manage Project Time

6. 5 Develop Schedule • Inputs to Develop Schedule ü Activity list and attributes ü Project Schedule Network Diagrams – relationships and dependencies ü Activity Resource Requirements ü Resource Calendars ü Activity Duration Estimates ü Project Scope Statement ü Project Scheduling Tool ü Scheduling Methodology and Standards ü Overall Project Calendar and Priorities BSBPMG 503 A Manage Project Time Monitor Initiation Planning Execution Close Control Adapted from PMBOK 4 th Edition

Critical Path & Critical Chain • Critical Path Method ü Was developed in the 1950 s by the Dupont Corporation ü The Critical Path Method, abbreviated CPM, or Critical Path Analysis, is a mathematically based algorithm for scheduling a set of project activities. ü It takes the activities in the Work Breakdown Structure, the durations and the interdependencies, and calculates the longest path through the project. ü It is the longest total duration of all the activities required to complete a project ü Advanced techniques and calculations (such as early start and early finish dates, and late start and late finish dates) are now carried out using project scheduling tools ü Does a forward and backward pass through the schedule with no regard for resource limitations Adapted from PMBOK 4 th Edition BSBPMG 503 A Manage Project Time

Critical Path and Critical Chain • Critical Chain Method ü Undertakes the same form of analysis and calculations, but takes into consideration the resource availability and constraints ü Takes the Critical Path and resource availability to produce a resource constrained critical path OR Critical Chain ü It is the longest total duration of all the activities required to complete a project, considering resource availability and limitations ü Often done simultaneously with Critical Path Critical Chain = Resource Constrained Critical Path Adapted from PMBOK 4 th Edition BSBPMG 503 A Manage Project Time

Schedule Compression Shortens the project schedule without changing project scope 1. Crashing ü Only works for activities where additional resources will shorten duration ü Does not always produce a viable schedule ü Always results in increased cost ü Sometimes results in increase risk increased Cost Crashing leads to increased Risk BSBPMG 503 A Manage Project Time

Schedule Compression Shortens the project schedule without changing project scope 2. Fast Tracking ü Phases or activities normally performed sequentially are performed in parallel ü Only works if activities can be overlapped to shorten duration ü May result in rework and increased risk ü Can result in decreased cost decreased Cost Fast Tracking leads to BSBPMG 503 A Manage Project Time increased Rework increased Risk
