ELC 347 project management Day 25

Agenda Course evaluations Today, we will discuss resource management Integrative Project Part 6 Due Dec 11 Any of the first five sections can be resubmitted for rescoring prior to finals week. The recorded score will the average of the original score and the score on the resubmitted section. Course evaluations Today, we will discuss resource management

Resource loading table The amounts of individual resources that a schedule requires during specific time periods. Resource loading table Resource Name Work Details 5/5 5/12 5/19 5/26 Bob 40 hrs 8h 32h Assign Bids Carol Calculate Cost Ted Documentation Alice 8 hrs Select Bid

Resource Leveling (Smoothing) A multivariate, combinatorial problem (hard to provide optimal solution) Objectives To determine the resource requirements so that they will be available at the right time To allow each activity to be scheduled with the smoothest possible transition across resource usage levels

Prioritization Rules for Leveling Smallest amount of slack Smallest duration Lowest ID number (FCFS) Greatest number of successor tasks Requiring the most resources

Resource leveling (method one) Develop resource leveling table Determine activity Late finish dates Identify resource Over allocation Level the resource loading table Requires more than one run-through due to ripple effects Examine conflicts (apply rules) Select activity to be reconfigured Start over, looking for more conflicts

A much better Way Use MS Project Enter resources Assign resources to tasks Use Resource leveling tool Sample resource leveling.mpp

Resource Loading charts Method two Create a project activity network diagram Develop resource loading table Determine activity late finish dates Identify resource over allocation Resource level the loading table

Creating Resource Loading Charts Display the amount of resources required as a function of time. 0 A 4 Res = 6 4 B 5 Res = 2 5 D 9 Res = 7 9 E 11 Res = 3 4 C 7 Res = 2 11 F 12 Res = 6 Start with a network diagram

Creating Resource Loading Charts Activity Resource Duration ES Slack LF A 6 4 B 2 1 5 C 3 11 D 7 9 E F 12 Produce a table that shows the duration, early start, late finish, slack, and resource(s) required for each activity.

Creating Resource Loading Charts Draw an initial loading chart with each activity scheduled at its ES. A 2 4 6 8 12 10 14 C B D E F Project Days Resources Resource imbalance

Creating Resource Loading Charts Rearrange activities within their slack to create a more level profile. Splitting C creates a more level project. A 2 4 6 8 12 10 14 C B D E F Project Days Resources
