Process: Integration, Scope & Schedule
The Process domain is half the exam. This lesson covers the first three knowledge areas that define what the project will do and when: Integration (the glue), Scope (the work), and Schedule (the timeline).
In this lesson
Integration management
Integration ties everything together. Key artifacts and processes:
- Project charter — authorises the project and the PM; created in Initiating. Without it, you have no authority.
- Project management plan — the integrated plan (all subsidiary plans plus baselines for scope, schedule and cost).
- Integrated change control — every change is evaluated for impact across all constraints; significant changes go to the Change Control Board (CCB).
- Lessons learned — captured throughout and rolled into organisational process assets at close.
Scope management & the WBS
Scope defines the work. The planning flow: collect requirements → define scope → create the WBS.
- The WBS (work breakdown structure) decomposes deliverables into smaller pieces; the lowest level is a work package. The 100% rule: the WBS captures all the work, and only the project's work.
- Validate Scope = the customer formally accepts deliverables (about acceptance).
- Control Scope = prevent scope creep (uncontrolled additions) and gold plating (extras nobody asked for).
Exam cue: distinguish Validate Scope (acceptance by the customer) from Control Quality (correctness, checked internally). Quality is checked before the deliverable is presented for validation.
Schedule & the critical path
Build the schedule by defining activities, sequencing them, estimating durations, and developing the schedule. The Critical Path Method (CPM) is essential:
- The critical path is the longest path of dependent activities — it sets the shortest possible project duration.
- Activities on the critical path have zero float (slack). Any delay there delays the whole project.
- Float / slack = how long an activity can slip without delaying the project:
Float = LS − ES = LF − EF(late start minus early start). - Leads let a successor start early; lags impose a wait between activities.
Schedule compression
| Technique | How | Trade-off |
|---|---|---|
| Crashing | Add resources to critical-path activities | Costs more money |
| Fast tracking | Do sequential activities in parallel | Adds risk and rework |
Note: Compress the critical path, not random activities — shortening non-critical work doesn't finish the project sooner. Try fast tracking first (free) before crashing (costly).
