What is Integrated Planning?

for Large, Complex Engineering & Construction Projects, Programmes & Portfolios

Integrated Planning is the single-source-of-truth discipline that fuses schedule, cost, risk, resources, scope, contracts, and performance data into one living, version-controlled model—typically built in Oracle Primavera P6—so that every decision is based on one coherent, real-time picture of the entire endeavour.

1. Why “Integrated” Matters at Scale

Fragmented Approach	Integrated Approach
Separate Excel schedules, cost spreadsheets, risk logs, EVM reports	One P6 database with cost-loaded, resource-driven activities linked to WBS, risk register, change orders, EV baselines
“Schedule says on-time, cost says over-budget”	CPI = 0.92, SPI = 0.88 calculated automatically from the same activity % complete
3-week lag to see impact of a scope change	What-if scenario run in <1 hour showing +14 days, +$2.1 M, 7% risk increase

2. Core Integration Pillars in Primavera P6

Pillar	What It Is	How It Connects in P6
Scope	WBS / EPS hierarchy	Activities roll up to control accounts; deliverables tied to milestones
Time	Critical-path schedule	Logic-driven, resource-leveled, baseline-protected
Cost	Budgets, forecasts, actuals	Cost-loaded activities → cash-flow S-curves, EAC
Resources	Labour, equipment, materials	Resource assignments drive duration, cost, EV
Risk	Threats & opportunities	Risk register linked to activities → Monte Carlo (Primavera Risk Analysis) → P80 contingency
Performance	Earned Value	PV, EV, AC calculated per period; CPI/SPI/TCPI dashboards
Contracts & Procurement	POs, variations	Cost codes aligned with WBS; change orders update budget & schedule in one click
Portfolio / Programme	Multiple projects	EPS roll-up → portfolio dashboards, cross-project resource histograms

3. Lifecycle View – Same Model, Different Lenses

Phase	Integrated Outputs (from one P6 file)
Concept / FEED	Feasibility schedule + Class-5 estimate + qualitative risk matrix + portfolio ranking
Detailed Design	Level-3 schedule, resource histograms, cost-loaded WBS, Monte Carlo P50/P90
Procurement	Long-lead tracking, vendor schedules synced via activity codes
Construction	Daily look-ahead, 3-week rolling, EVM variance reports, risk-adjusted forecast
Commissioning	Startup logic sequences, system turnover milestones, final EAC vs BAC
Closeout	As-built schedule, lessons-learned tagged to WBS, portfolio KPI archive

4. Real-World Impact (Quantified)

Metric	Typical Improvement
Schedule adherence	+25–35 % (critical path visible & protected)
Cost forecast accuracy	±5 % at 60 % complete (vs ±15 % in silos)
Contingency drawdown	15–20 % reduction via Monte Carlo risk integration
Change-order cycle time	70 % faster impact assessment
Executive decision latency	From weeks → same-day dashboard review

5. Portfolio & Programme Layer

• Enterprise Project Structure (EPS) groups 10–200+ projects.
• Cross-project resource pools prevent overallocation.
• Portfolio dashboards show combined CPI/SPI, risk heat-map, capital burn rate.
• Scenario planning: “What if we accelerate Project A by 3 months—impact on cash and manpower?”

6. One Sentence Definition

Integrated Planning = a single, cost-loaded, resource-driven, risk-adjusted Primavera P6 model that synchronises scope, time, cost, and performance across every project, programme, and portfolio level—so stakeholders always act on the same version of the truth.
