Introduction to Project Time Management n Includes the processes required to ensure timely completion of the project. n The major processes in developing the project time schedule are: – Activity Definition – Activity Sequencing – Activity Duraton Estimating – Schedule Development – Schedule Control

Activity Definition n Activity Definition – Identifying and documenting the specific activities that must be performed to produce the various project derivables and subderivables identified in the WBS n Inputs to Activity Definition 1. Work Breakdown structure 2. Scope statement 3. Historical information 4. Constrants 5. Assumptions 6. Expert judgment n Tools and Techniques for Activity Definition 1. Decomposition 2. Templates

Activity Definition (cont.) n Outputs from Activity Definition 1. Activity list 2. Supporting detail 3. Work breakdown structure update

Activity Sequencing n Definition – Identifying and documenting interactivity logical relationships. n Inputs to Activity Sequencing 1. Activity list 2. Product description 3. Mandatory dependencies 4. Discretionary dependencies 5. External dependencies 6. Milestones n Tools and Techniques for Activity Sequencing 1. Precedence diagramming method (PDM) (fig 6-2) 2. Arrow diagramming method (ADM) (fig 6-3) 3. Conditional diagramming methods 4. Network templates

Activity Sequencing (cont.) n Outputs from Activity Sequencing 1. Project network diagrams (fig 6-2 and fig 6-3) 2. Activity list updates

Activity Duration Estimating n Definition – Taking information on the project scope and resources and then developing durations for input to schedules n Inputs to Activity Duration Estimating 1.

Simulation 4. Resource leveling heuristics 5. Project management software 6. Coding structure

Schedule Development (cont.) n Outputs from Schedule Development 1. Project Schedule  Project network diagrams with date information added (fig 6-5)  Bar Charts or Gantt charts (fig 6-6)  Milestone charts (fig 6-7) 2. Supporting detail 3. Schedule management plan 4. Resource requirement updates

Schedule Control n Definition – Controlling changes to the project schedule n Inputs to Schedule Control 1. Project schedule 2. Performance reports 3. Change requests 4. Schedule management plan n Tools and Techniques for Scope Change Control 1. Schedule change control system 2. Performance measurement 3. Additional planning 4. Project management software 5. Variance analysis

Schedule Control (cont.) n Outputs from Scope Change Control 1. Schedule updates 2. Corrective action 3. Lessons learned
