BSBPMG503A Manage Project Time 6.3 Estimate Activity Resources The process of estimating the type and quantities of material, people, equipment or supplies required to perform each activity Closely related to the Estimate Costs process (7.1) and normally done simultaneously Sometimes the resources are captured in project management software, most particularly human resources Supplementary registers are often maintained for non human resources Occurs during the Planning Phase Adapted from PMBOK 4 th Edition InitiationPlanning ExecutionClose Monitor Control

4. BSBPMG503A Manage Project Time Practical Tips to Estimate Duration Experience has taught me that often the best way to estimate the duration of an activity is to ask the person who will be performing the activity to make an estimate I have also learnt that most people are – –Optimistic so that they underestimate the work effort required; –Assume they are productive for more hours per day than they really are; and –Fail to include rework and sign off activities as part of their estimate In practice I will double, or sometimes triple, these estimates before putting them in the project schedule
