The Project Life Cycle is broken down into 5 phases:
-
- Project Initiation
- Project Planning
- Project Execution
- Project Monitoring & Controlling
- Project Closeout
Let’s look at the 4th phase, Project Monitoring & Controlling, in detail.
Desired Outcome
The fourth phase in the Project Life Cycle is Project Monitoring & Controlling.
The desired outcome of this phase is ensuring that the project results are being delivered according to the Project Plan, and take corrective or preventive action if necessary. Your goal is to assess progress and react. In this phase you’ll integrate new information into the problem domain, manage trade-offs, and do your best to address problems as they arise.
As you make changes to the project plan, you’ll need to ensure that all of project stakeholders, plans, estimates and resources are adjusted accordingly.
Inputs & Outputs
Each phase of the project life cycle transforms inputs from the previous phase into outputs for the next phase. The following inputs/output diagram showcases a high-level view of the inputs and outputs. Inside the ‘black box’ is where the transformation of inputs into outputs occurs.

Project Monitoring & Controlling: Systems (Input/Output) Diagram
In this phase, the ‘inputs’ that initiate the monitoring and controlling process are:
- Deliverables
- Change Requests (to expand/reduce scope, quality, schedule or cost baselines)
You’ll either be reviewing work results against the initial acceptance criteria, or considering change requests from multiple stakeholders. Throughout a rigorous ‘change control’ process, the project manager will ensure that changes to the Project Plan and Specifications are agreed upon, managed, and communicated to all stakeholders.
The outputs of this phase include:
- Accepted Deliverables
- Approved Change Requests
Key Activities
Now that we understand the required inputs and desired outputs of this phase, it’s time to look at the key activities that must be undertaken.

Main Takeaway
Project Monitoring & Controlling is about progress review and response.
- Review the status of the project’s deliverables, schedule, costs, etc.
- Identify corrective actions/measures to ensure successful project completion.
- Manage changes to the project’s scopes, baselines, estimates and/or forecasts.
- Ensure changes in one area are integrated into other project areas.
In the next post, I’ll cover Phase 5, Closeout, of the Project Life Cycle.
