PMI more precisely calls them process groups: related management processes that can overlap, repeat, and run inside project life-cycle phases rather than five rigid, one-way stages.
What the five phases really mean
The five-part model gives a project team a shared way to decide what must happen, when decisions are needed, and how work will be accepted. It is a framework, not a universal methodology. Teams tailor the processes to the project’s size, risk, delivery method, industry, and governance requirements.
| Process group | Primary purpose | Typical work | Key decisions or outputs | Connection to other groups |
|---|---|---|---|---|
| Initiating | Authorize a project or phase | Clarify the need, goals, constraints, justification, and stakeholders | Authorization to proceed; initial objectives and stakeholder understanding | Provides the direction that planning develops |
| Planning | Define objectives and a workable course of action | Set scope, acceptance criteria, schedule, budget, resources, risks, quality, communications, procurement, and dependencies | Integrated project plans, baselines, milestones, and approved approach | Is refined as more is learned and guides execution |
| Executing | Carry out the approved plan | Coordinate people and resources, develop the team, share information, perform the work, and implement approved changes | Deliverables and documented work products | Runs alongside monitoring and controlling |
| Monitoring and Controlling | Compare actual results with expectations and respond | Track schedule, cost, quality, risks, performance, issues, and changes | Progress reports, variance analysis, corrective actions, and controlled changes | Feeds adjustments back into planning and execution |
| Closing | Finish and transition a project or phase formally | Confirm acceptance, close contracts and administration, archive records, and capture lessons | Accepted outcome, completed handoff, closed records, and lessons learned | Confirms that remaining obligations are resolved |
1. Initiating: authorize the work
Initiating turns an idea or business need into an authorized project or phase. The team establishes why the work matters before investing heavily in detailed plans.
What happens during Initiating
- Define the problem, opportunity, expected outcomes, and high-level objectives.
- Identify major constraints such as time, budget, regulatory requirements, technology, or available staff.
- Identify stakeholders, decision-makers, sponsors, customers, and groups affected by the outcome.
- Clarify the project’s justification and how success will be recognized.
- Obtain authorization to proceed and establish who can make key decisions.
The result is enough shared direction to decide that the project should exist. Detailed estimates, task assignments, and risk responses belong primarily in Planning, although early assumptions may be recorded here.

2. Planning: choose a workable approach
Planning translates objectives into a coordinated approach for producing and accepting the result. It is not a single meeting or a document written once: estimates, dependencies, risks, and stakeholder needs often require repeated refinement.
Core planning decisions
- Scope and acceptance: Define what is included, what is excluded, the deliverables, and the criteria customers or sponsors will use to accept them.
- Schedule: Sequence activities, identify dependencies, set milestones, and establish realistic dates.
- Cost and resources: Estimate the budget, assign people and equipment, and obtain the required approvals.
- Risk and issues: Identify uncertainty, assess exposure, and select responses such as avoiding, reducing, transferring, or accepting a risk.
- Quality: Set standards, review points, tests, and responsibilities for verifying that work meets requirements.
- Communications: Decide who needs which information, in what format, how often, and through which channel.
- Procurement and dependencies: Plan external purchases, contracts, approvals, and relationships with other projects or operational teams.
Good planning makes trade-offs visible. If a deadline cannot move, for example, the team may need more resources, reduced scope, or greater tolerance for risk. The chosen approach becomes the reference point that Monitoring and Controlling uses to identify meaningful variance.
3. Executing: perform the planned work
Executing is where the team coordinates people and resources to create the planned deliverables. Project leadership includes assigning and supporting the team, resolving day-to-day obstacles, communicating information, managing suppliers, and maintaining productive collaboration.
Typical execution activities
- Perform the technical, design, construction, research, or operational tasks that produce deliverables.
- Develop and support the project team, clarify responsibilities, and coordinate specialists.
- Distribute project information and maintain communication with stakeholders.
- Manage suppliers and contract work in line with agreed requirements.
- Implement changes only through the project’s agreed change-control approach.
Execution does not mean following a plan blindly. When approved changes or new information alter the work, the plan and relevant baselines may be updated through controlled decisions.

4. Monitoring and Controlling: measure, compare, and adjust
Monitoring and Controlling runs alongside execution. The team measures actual performance against the approved approach, communicates what it finds, and takes action when results, assumptions, or conditions change.
What the team monitors
- Progress against milestones and schedule commitments
- Actual and forecast costs against the budget
- Deliverable quality and acceptance results
- Risks, issues, dependencies, and unresolved decisions
- Resource use, team capacity, and overall performance
- Requests for changes to scope, time, cost, quality, or requirements
How control works
Control is more than reporting a status color. The team analyzes the size and cause of a variance, forecasts its effect, and selects a response. That may involve corrective action, preventive action, re-planning, escalation, or a formally approved change. Monitoring may reveal that an assumption was wrong; the resulting decision can send work back into Planning while execution continues elsewhere.

5. Closing: obtain acceptance and finish cleanly
Closing formally completes a project or phase and transfers the result to its owner, customer, operator, or next phase. A team can finish the build and still have an incomplete project if acceptance, contracts, records, or administrative obligations remain open.
Closing checklist
- Confirm that the sponsor or customer has accepted the deliverables against the agreed criteria.
- Complete handoff, operational documentation, training, support arrangements, and ownership transfer where applicable.
- Close procurements, contracts, invoices, permissions, and outstanding administrative work.
- Archive plans, decisions, requirements, test evidence, approvals, and other records according to organizational rules.
- Capture lessons learned, including what should be repeated or changed on future work.
- Release project resources and communicate the formal end of the project or phase.
Are the five phases sequential?
Not in the strict sense. The familiar order is useful for explaining the flow of a project, but PMI describes these as an integrated set of processes applied iteratively and revised as needed. Planning can continue after execution begins, and Monitoring and Controlling interacts with execution rather than starting only after all delivery work is complete.
Best Value
A project can also contain several life-cycle phases—such as design, build, and rollout—with the five process groups applied within each phase. Closing one phase may authorize the next, while lessons or discoveries from later work can require earlier plans to be revisited.
How the model works in agile projects
The process groups are not limited to waterfall delivery. In an agile project, Initiating may establish the product vision, funding, governance, and initial stakeholders; Planning may occur at the product, release, iteration, and daily-work levels; Executing happens through incremental development; and Monitoring and Controlling uses reviews, demonstrations, metrics, risk conversations, and retrospectives to adapt the backlog and approach. Closing may occur at the end of an iteration, release, or the entire product effort.
The team decides which processes are necessary and how much documentation or approval is proportionate to the project’s risk. Iterative delivery changes the timing and granularity of the work, not the need to authorize, plan, deliver, inspect, adapt, and formally finish.
Using the five groups without turning them into a rigid checklist
- Start with the decision to invest. Make the need, expected outcome, sponsor, and constraints clear before detailed work begins.
- Plan to the level of uncertainty. Establish enough scope, schedule, cost, risk, quality, and communication detail to make informed commitments; refine it as evidence improves.
- Deliver while measuring. Treat execution and monitoring as concurrent activities, with visible progress and timely escalation.
- Control changes deliberately. Evaluate effects on objectives and constraints before approving, rejecting, or deferring a change.
- Close every obligation. Acceptance, handoff, contracts, records, and learning are part of completion, not optional paperwork after the “real” work.
This approach preserves the value of the five-group model while allowing predictive, agile, hybrid, and highly regulated teams to tailor how it is applied.
