9. Slide 5 Definitive Definitions Planned Value Estimate of Wrench-hours for an activity Earned Value % complete of a planned activity based on field status Actual Value Cost measurement; also used to measure worker performance Longest Job Zero-float, determines the duration of the outage Not to be confused with critical path, which accounts for risk
10. Slide 6 Definitive Definitions – cont’d S-Curve Chart of values distributed along wrench-hour/time x y axis Baseline A snapshot of the initial plan/schedule before feed-out Performance Earned vs. Planned, Actual vs. Earned, Actual vs. Planned What-if Scenarios Leveling a programmed plan to determine the best case scenario based on cost, schedule duration, and wrench-hours
17. Slide 10 The 4+ Key Performance Indicators Worker Performance… Set realistic direct wrench-time for worker performance No more than 75% Remember, once you determine direct wrench-hours all indirect resources and logistics are based on this number If you don’t use strategic planning to support this number your chances of achieving this target will be diminished Use productivity factors based on: season, location, worker experience, resource availability (inspectors, cranes, etc.)
18. Slide 11 The 4+ Key Performance Indicators Schedule… Establish a schedule in your planning software with a clearly defined WBS (Work Breakdown Structure) and Phase The WBS is a vertical hierarchy of physical locations The Phase is a horizontal section of work types Use What-if Scenarios to determine the longest job (series of planned activities with no float) Control the longest job; manage the remaining tasks
19. Slide 12 The 4+ Key Performance Indicators Cost… The cost is based on Work-scope + Indirects + Contingency = Budget Costs can only be controlled through Work-scope changes Costs are managed, not controlled, through performance Costs need to be measurable based on direct and indirect; found and added; WBS and Phase
