#3PM3_T_B Planning TimeActivity Resource EstimatingActivity Resource Estimating involves:Selection of the correct resources to perform the task (Who will do the job?)Estimation of the correct amount of effort/expenditure required (ie. How many labour hours/$ of material etc. will they use?)Selection of the correct rate of expenditure (ie. How many hours/day can they?)

#3PM3_T_B Planning TimeSelecting Resources: The Resource SheetScheduling tools contain a Resource Sheet that defines the resources derived from the Resource Breakdown Structure (RBS)This sheet is occasionally custom built by the scheduler, but usually is stored with a company template schedule that also contains various other standard formats (eg. Standard working hours, company stat holidays, etc.)Either way, the sheet must:Tie in to cost accounting system each resource has a typical dollar rate, and may have different overheads attached Typically reflects the Organizational Breakdown Structure (OBS ie. The org chart

#3PM3_T_B Planning TimeSelecting Resources: The Responsibility Assignment MatrixProject Manager identifies required skills and matches with functional groups on the Resource Sheet based on experience or organizational Responsibility Allocation Matrix (RAM)The RAM is a table which lists the jobs/ responsibilities/ work products for different functions or people within the team or organizationDiscussed in detail in Team Leadership

#3PM3_T_B Planning TimeDefinition of Estimate AmountThe resource estimate is developed in the same way as the duration estimate:Expert opinionAnalagous estimatingProbabilistic methods Since the amount of resources used on the project is directly related to the program cost, this is typically performed as part of the Cost Planning process, using the Basis of Estimate (BOE) formIf detailed enough, BOE is provided to the scheduler to transcribe to the scheduler If not, team lead or PM breaks out BOE amount to the activity level

#3PM3_T_B Planning TimeDefinition of Resource Expenditure RateDuring preliminary scheduling, some SW packages will apply pre-programmed distributions:Front-end load: eg. Program PlanningBack-end load: eg. Customer SupportUniform (usual default): eg. Team ManagementDuring detailed scheduling, expenditure rate driven by trade-offs between:schedule compliance requirements; and team availability as determined by discussions with functional management

#3PM3_T_B Planning TimeTypical Resource Estimation ProcessProject Manager and Team Leads/Functions jointly develop the Activity ListTeam Leads/Functions submit estimates on activity list and/or BOE form, and Project Manager approvesTeam Lead or Project Manager enter estimates into scheduling tool using ideal activity durations driven by external milestones aloneTeam Lead and Project Manager review resource expenditure rate generated by scheduling tool, and adjust team size to meet, or engage in Resource Levelling (to be discussed hereafter)
