Project Time Management
\[!note\] Overview This note covers Background on Project Management, Project Scope Management, and Project Cost Management, structured for Obsidian's graph view and outline. Use [[wikilinks]] between sections to build a knowledge map.1. Background on [[Project Management]]
Project Management is the application of processes, knowledge, skills, and experience to achieve project objectives.
Project Manager — a person assigned by the performing organization to lead the team responsible for achieving project objectives.
What does a Project Manager do?
Primary task: Planning (project management plan: direction, WBS, critical path, timeline, budget)
Other responsibilities:
What is Planning?
Planning divides project activity into:
2. [[Project Process Groups]] & [[Knowledge Areas]]
5 Process Groups

10 Knowledge Areas
3. [[Project Integration Management]]
Integrates all other knowledge areas; produces the Project Charter (most important input to project management).
Roles of PM in Integration

4. [[Project Management Plan]]
The process of defining, preparing, and coordinating all subsidiary plans and baselines into one comprehensive plan.
Subsidiary Plans (9)
Inputs & Outputs
| Inputs | Tools & Techniques | Output |
|---|---|---|
| Project Charter, EEF, OPA | Expert Judgment, Data Gathering, Interpersonal/Team Skills, Meetings | Project Management Plan |
What the Plan Explains
Baseline Plans = Scope + Time + Cost → combined with the 9 subsidiary plans = Project Management Plan
5. [[Project Scope Management]]
What is a Constraint?
The Triple Constraint: Scope, Cost, Time — plus Quality, Risk, Resource (six total).

| Project Risk | Project Quality Issues | Project Resources |
|---|---|---|
| Scope creep, Budget creep, Communication issues, Lack of clarity, Poor scheduling | Defects, Deficiencies, Variation in expected appearance/performance | Labor, Equipment, Materials, Money, Space, Service, Time |
Project Scope vs Product Scope
| Product Scope | Project Scope |

5.5 Create [[Work Breakdown Structure (WBS)]]
Deliverable-oriented breakdown of the project into smaller, manageable components.

P1 --> W1[Work Package] & W2[Work Package] & W3[Work Package]

WBS is an input to: Cost Estimating, Cost Budgeting, Risk Planning, Resource Planning, Activity Definition.

Baseline: the approved starting point used to measure progress.
Scope Baseline = Scope Statement + WBS + WBS Dictionary.

5.7 Scope Creep
Uncontrolled expansion of project/product scope without adjusting time, cost, resources. Caused by stakeholder requirement changes or internal miscommunication.

| Inputs | Tools & Techniques | Outputs |
|---|---|---|
| Project mgmt plan, Project documents, Verified deliverables, Work performance data | Inspection, Decision making | Work performance info, Accepted deliverables, Change requests, Project document updates |

7. [[Earned Value Management (EVM)]]
A systematic process using earned value to integrate cost, schedule, technical performance, and risk management.
Core Metrics
| Term | Meaning |
|---|---|
| PV (Planned Value) | Authorized budget assigned to scheduled work; cumulative PV = BAC |
| EV (Earned Value) | Value of work actually completed to date |
| AC (Actual Cost) | Cost incurred to execute the work |
| BAC (Budget at Completion) | Sum of all budgets allocated = total PV |
Variance & Index Formulas
| Metric | Formula | Interpretation |
|---|---|---|
| Schedule Variance (SV) | EV − PV | Negative = behind schedule |
| Cost Variance (CV) | EV − AC | Negative = over budget |
| Variance at Completion (VAC) | BAC − EAC | Over/under budget forecast |
| Schedule Performance Index (SPI) | EV / PV | <1 = behind schedule |
| Cost Performance Index (CPI) | EV / AC | <1 = over budget |
| Estimate to Complete (ETC) | EAC − AC | Money needed to finish |
| To-Complete Performance Index (TCPI) | (BAC − EV) / (BAC − AC) | Ratio of remaining work to remaining funds |
\[!warning\] Note on Schedule Variance SV is derived from cost data, not the real schedule — it doesn't distinguish critical-path vs non-critical-path work. The true schedule status comes from the [[Critical Path]] (precedence/network diagrams) — the longest path from Start to Finish.
