2 Integrated Project Planning

Set the planning foundation

An integrated project plan brings together decisions about what work will be done, when it will happen, who and what are needed, how results will be accepted, what will be purchased, and how progress will be measured. These parts must agree: a change in scope can alter the schedule, resource needs, quality checks, procurement, and success measures. Integration gives the team a shared basis for decisions.

Begin by translating the project’s purpose into specific outcomes and acceptance conditions. Document assumptions, constraints, dependencies, and risks because each can shape the work. If an important assumption fails, assess its effects across the plan rather than changing only one date or estimate.

Define scope, schedule, and resources

Describe the product, service, or result to be delivered, identify what is included and excluded, and state how each deliverable will be accepted. Break the work into manageable components, often using a work breakdown structure (WBS), so estimates, responsibilities, and progress can be connected to defined work.

For a customer booking website, the scope might include user registration, appointment booking, testing, and launch support, while explicitly excluding a mobile app. Acceptance criteria might require that users can complete a booking and receive confirmation.

Build a feasible schedule

Turn work packages into activities, estimate durations, identify dependencies, and set milestones. Include review, testing, approvals, and procurement lead times, not just production work. Check that the schedule fits resource availability and other constraints. Logic-based scheduling helps reveal the critical path and the effect of delays on completion.

Match resources to the work

Identify the people, skills, equipment, facilities, and funding needed for each activity. Name accountable owners, confirm when resources will be available, and resolve over-allocation. Resource estimates should fit both the work and the schedule; an activity is not feasible if its required specialist is unavailable.

Plan quality and procurement

For each deliverable, define measurable quality criteria, verification methods, responsible reviewers, and acceptance authority. Schedule quality activities, such as inspections, tests, peer reviews, or user acceptance, and provide the resources they require. For the booking website, quality checks might specify browser compatibility and successful end-to-end booking tests before acceptance.

Coordinate purchases and suppliers

Decide which needs will be met by purchasing goods or services. Define requirements, selection criteria, approval responsibilities, contract or order milestones, delivery dates, and how supplier performance and deliverables will be checked. Coordinate procurement with scope, quality, and schedule: a needed component must be specified, ordered, delivered, and accepted in time for dependent work. Early coordination among project, technical, procurement, and quality stakeholders can reduce delays and mismatched requirements.

Measure progress and results

Choose indicators that show both delivery progress and whether intended project results are being achieved. For each measure, specify its definition, target or tolerance, data source, collection frequency, and owner. Measures may include milestone completion, accepted deliverables, defect rates, spending, schedule variance, or user adoption.

Compare actual performance with approved plans, explain significant variances, and use forecasts to identify likely outcomes as well as reviewing past performance. A measurement baseline connects authorized scope, schedule, and cost for tracking execution.

Approve and maintain the integrated plan

Before approval, check the plans together for each major deliverable: Is the work defined and scheduled with its dependencies? Are the resources available? Are quality criteria and acceptance responsibilities clear? Are purchases and supplier dates included? Can progress and completion be measured?

After stakeholders approve the plan, establish agreed baselines and manage proposed changes through a defined review process. Evaluate each change for effects on scope, dates, cost, resources, quality, procurement, risks, and measures. Approve and communicate changes before updating affected plans and baselines. A schedule baseline is useful for comparison only when actual progress and forecasts are maintained against it.

Keep assumptions and constraints visible, make dependencies clear, and ensure every deliverable has an owner, a feasible schedule, acceptance criteria, and a way to track progress. When conditions change, assess and update the connected plans together.
