Core Framework

PMI-SP Schedule Management Framework

PMI-SP covers schedule management from planning through control. The exam requires performing network diagram calculations, EVM calculations, and making schedule compression decisions. Know the formulas and when to apply each schedule optimization technique.

  1. 01
    Schedule Planning — Define activities, sequence, estimate durations
  2. 02
    Network Diagramming — PDM (Precedence Diagramming Method), dependencies (FS, SS, FF, SF)
  3. 03
    Critical Path Analysis — Forward/backward pass, float calculation, critical path identification
  4. 04
    Schedule Optimization — Resource leveling, fast-tracking, crashing
  5. 05
    Earned Value Management — SV, SPI, CV, CPI, EAC, ETC, TCPI for schedule performance
Scenario Traps

Wrong instinct vs correct approach

A project is behind schedule and the customer needs the deadline met
✕ Wrong instinct

Add resources to all activities to speed everything up

✓ Correct approach

Only adding resources to critical path activities reduces project duration (crashing); adding resources to non-critical path activities doesn't shorten the schedule. Identify the critical path first, then crash only cost-efficient activities on it.

SPI is 0.8 and the project is 50% through
✕ Wrong instinct

The project will recover since performance often improves in later phases

✓ Correct approach

SPI of 0.8 means only $0.80 of work has been completed for every dollar planned. Early SPI is the best predictor of final performance. Develop a schedule recovery plan immediately.

Two parallel activities have a SS relationship with a 3-day lag
✕ Wrong instinct

Activity B can start 3 days after the project start

✓ Correct approach

SS+3 means Activity B can start 3 days after Activity A starts — not 3 days after the project starts. The lag is calculated from when Activity A begins.

Quick Rules

Know these cold

  • ▸ Fast-tracking = parallel sequencing (more risk); Crashing = add resources (more cost)
  • ▸ Critical path = longest path through the network = zero total float
  • ▸ SV = EV - PV; CV = EV - AC; SPI = EV/PV; CPI = EV/AC
  • ▸ SPI > 1 = ahead; SPI < 1 = behind; CPI > 1 = under budget; CPI < 1 = over budget
  • ▸ Crash only critical path activities — crashing non-critical activities wastes money
  • ▸ Free float affects only that activity; total float affects the entire path
  • ▸ EAC = AC + ETC; TCPI = (BAC - EV) / (BAC - AC)

Failure Patterns

Common Exam Mistakes — What candidates get wrong

Confusing fast-tracking with crashing

Fast-tracking performs activities in parallel that were planned sequentially — it increases risk but uses existing resources. Crashing adds resources to critical path activities — it increases cost. Candidates apply the wrong technique when cost vs. risk is the stated constraint.

Misidentifying dependency types in network diagrams

FS: B cannot start until A finishes. SS: B cannot start until A starts. FF: B cannot finish until A finishes. SF: B cannot finish until A starts. SF is rare and often misidentified in exam questions.

Calculating float incorrectly

Total Float = LS - ES (or LF - EF). Free Float = ES of next activity - EF of current activity. Critical path has zero total float. Candidates confuse these calculations or make arithmetic errors on forward/backward pass questions.

Misidentifying EVM schedule health indicators

SV = EV - PV. SPI = EV/PV. SPI > 1 means ahead of schedule. SPI < 1 means behind. Candidates who interpret positive/negative variance backwards make wrong schedule health assessments.

Ignoring resource constraints in critical path analysis

The critical path method assumes unlimited resources. In reality, resource constraints create resource-critical paths that may be longer than the unconstrained critical path — candidates who ignore this fail constrained scheduling questions.

PMI-SP tests schedule precision under pressure. Test whether you can calculate and interpret project schedule health correctly.
