Project Management Execution Phase: A Complete Step-by-Step Guide

KEY TAKEAWAYS

• Project execution focuses on implementing the strategies outlined in the project plan.
• The key components of project execution include task management, resource allocation, stakeholder communication, and quality assurance.
• Agile, waterfall, and hybrid are popular project management methodologies typically used for project execution.

The project management execution phase is where the team carries out the work and where most problems tend to surface. With the project plan approved, the team must focus on coordinating tasks, managing resources, and ensuring work meets project objectives. To help you get through to successful delivery, this article breaks down the key activities, common challenges, and proven methodologies you can apply during the project execution phase.

Phase	Overview
1. Initiation	Defines the project’s purpose, scope, and stakeholders; determines if the project is feasible and worth pursuing.
2. Planning	Outlines the roadmap, including timeline, resources, budget, risks, and deliverables.
3. Execution	The team completes the work and produces deliverables based on the project plan.
4. Monitoring & Control	Tracks progress, manages changes, and ensures the project stays on scope, time, and budget.
5. Closure	Finalizes deliverables, obtains approvals, and documents lessons learned.

What is the project management execution phase?

Project execution is the third of the five phases of project management, where the team performs the actual work to produce the deliverables outlined in the project plan. To achieve the expected outcomes, this phase involves carrying out a number of activities, such as executing timelines, allocating resources, and collaborating on the work as a group.

According to the most recent PMBOK® Guide, project work centers on coordinating people, resources, and activities to deliver project outcomes while maintaining strong stakeholder engagement. This is typically where the majority of project effort and resources are applied. At this stage, the project manager’s role shifts from planning to actively leading execution, facilitating team performance, and ensuring alignment with project objectives and value delivery.

Project execution vs. monitoring and controlling

Project execution runs in parallel with the monitoring and control phase to ensure progress is continuously measured against the plan and to address any potential issues that may impact the results. 

Their difference lies in their focus—execution is concerned with doing the work and producing deliverables, while monitoring and controlling is concerned with evaluating that work by tracking scope, schedule, budget, and quality in real-time.

It is important to treat these two phases as a feedback loop: execution surfaces what’s happening on the ground, and monitoring determines whether that’s good enough or whether something needs to change.

6 key activities of the project execution phase

The project execution phase involves a wide range of activities, from assigning tasks and allocating resources to tracking progress and managing dependencies. Communication is critical throughout this phase as teams are often working across multiple workstreams simultaneously.

1. Assigning tasks and responsibilities

Once the project kicks off, the project manager breaks down the project plan into specific tasks and assigns them to the right team members based on their skills and availability. Each task should be clearly defined so the owner understands what they need to deliver and the deadline for completion, often using a RACI matrix to clarify roles and ensure accountability.

2. Managing and allocating resources

Resource management is an ongoing activity throughout the execution phase. This means verifying team members are available as scheduled, the budget is released and accessible, and the required materials are in place before work begins.

When resource conflicts arise, the project manager steps in to address them before they impact delivery, whether that means negotiating priorities, securing external support, or adjusting the budget.

3. Managing dependencies and deliverables

Most tasks within a project are connected, where one team’s output is often the starting point for another team’s work. The project manager maps these dependencies so that the next task can begin on time. On the deliverables side, each output is tracked against its agreed milestone and is only considered complete when it meets the acceptance criteria defined during planning. 

4. Tracking project progress

As work moves forward, the project manager continuously monitors how the project is performing against the original plan. This includes tracking key performance indicators (KPIs) such as schedule variance, budget spend, and task completion rates. Tools such as Gantt charts, dashboards, and status reports provide an accurate view of project progress in real-time. 

5. Reporting to stakeholders

Project managers provide regular status updates to stakeholders based on the communication frequency defined in the project plan. These reports often provide a high-level view of project health and highlight decisions that require stakeholder input. Communication runs both ways, so stakeholders can share feedback and flag concerns as the project progresses.

6. Implement quality assurance processes

Quality assurance ensures that deliverables meet the standards and acceptance criteria established during the planning phase. The project manager establishes review checkpoints at certain project stages to assess the delivered outputs. When a deliverable falls short of the agreed standard, it is sent back for revision rather than passed on to the next stage.

What is a project execution plan (PEP)?

A project execution plan (PEP) is a framework that outlines how a project will be carried out from start to finish. It defines the management approach for the execution phase, which includes roles and responsibilities, communication protocols, risk management, and quality standards.

The PEP is typically developed before execution begins, connecting high-level project strategy to operational work. For the project manager, it serves as the primary reference point throughout execution and a performance measure to assess whether the project is on track to meet its objectives.

Unlike a project schedule, which focuses on timelines, task sequencing, and deadlines, the PEP defines how the work will be managed and delivered. The schedule is one component of the broader execution plan.

Common methodologies for project execution

Agile, Waterfall, and hybrid are among the most widely used methodologies in project execution, each offering a different approach to managing work and delivering outcomes. The right methodology depends on the nature of the project, the level of flexibility required, and the expectations of the stakeholders involved.

• Waterfall: This linear approach to project management follows a sequential progression, where each project phase is concluded before advancing to the next. The Waterfall methodology is most appropriate for projects characterized by well-defined requirements and a comprehensive understanding of the final product.
• PRINCE2: This process-based approach is divided into stages, and each stage must be reviewed and justified before work on the next stage is approved. It is most fitting for projects that prioritize risk management and quality control.
• Agile: Projects are delivered in short iterative cycles, allowing teams to adapt to changes and continuously improve outputs throughout the execution phase. Common Agile frameworks include Scrum and Kanban.
• Hybrid (Agile + Waterfall): There is no universally accepted hybrid approach, but a common starting point is to follow a Waterfall structure for planning while executing delivery in iterative Agile cycles, combining predictability with flexibility.
• Six Sigma: This methodology focuses on reducing product defects and enhancing overall quality. It is particularly effective for projects emphasizing quality control and the enhancement of processes.

Project execution gaps & best practices

Issues during project execution are inevitable, but most stem from poor planning around resources, risks, and communication. Below are some of the most common execution gaps project managers encounter and how to address them.

1. Unclear task ownership
2. Lack of communication
3. Scope creep
4. Inadequate resource planning
5. Lack of risk management
6. Poor change management
7. Insufficient progress tracking
8. Misaligned stakeholder expectations

Strategies for successful project execution

While every project is different, the most successful ones share a common set of practices that guide how project managers respond to conflicts and issues.

1. Define clear ownership for every task: Every task should have one owner who is accountable for its completion and output quality.
2. Communicate consistently: Establish a communication cadence and stick to it to keep stakeholders and team members updated.
3. Track progress in real-time: Do not wait for a milestone to find out the project is behind. Monitor task completion and budget spending regularly. 
4. Address risks early: Identify potential risks before execution begins and have a response plan ready so that issues are resolved before they impact delivery.
5. Control scope changes: Every change request should undergo a formal review process to assess its impact on timeline, budget, and resources before approval.

Next step: Monitoring & controlling

The project execution phase is where the majority of project work takes place, but delivering successfully also requires continuous monitoring. In the next article, we cover the monitoring and controlling phase, which focuses on measuring project performance and addressing issues before they affect the project outcome.
