Monitoring and controlling in project management means comparing actual work with the approved plan, investigating deviations, and deciding what needs to change. Done throughout delivery, it helps teams respond before a problem becomes a missed deadline or budget overrun.
That problem can begin while the project still appears on track. A client requests another revision, and the team fits it into the sprint without moving the delivery date. The next report stays green because the milestone remains achievable. What it leaves unexplained is how much of the remaining budget that revision will consume.
One addition may be manageable. Several can leave too little budget for the work originally promised. This is how scope creep leads to project overruns: the team takes on extra work while its estimate still reflects the original agreement. How can a manager recognize that drift while the weekly report still shows the project on track?
What Monitoring and Controlling in Project Management Covers
Monitoring compares actual progress with the approved plan. Control uses the findings to determine whether a response is needed and carry it through. Both continue during execution, as described in the Project Management Institute’s guidance on monitoring and controlling.
A team may log more hours than planned because a task was underestimated, requirements changed, or completed work needed correction. The same variance can therefore point to different problems. Establishing the cause helps the manager choose a response that addresses the work rather than simply adjusting the reported number.
A critical approval is overdue
Arrange an authorized backup or resequence unaffected work
Remaining effort exceeds the allowance
Assess whether a different delivery approach can reduce the forecast overrun
New requests appear in active tasks
Determine whether the requests are covered by approved scope or need a change request
Each decision needs follow-up. A backup approver may clear the immediate blocker, yet the wait may already have pushed dependent work back. Project monitoring and controlling checks whether the team can still meet its commitments after the blocker is removed.
The project control phase continues as the team revises its plans. Those revisions must leave the earlier commitments visible. Otherwise, moving a deadline can make the next report look healthy without showing the delay.
The Baseline Makes the Comparison Meaningful
A project baseline records the approved work, timing, and budget. It gives the manager a stable reference when estimates change, so a revised plan does not hide a developing overrun.
If a feature takes longer than expected, the scope baseline helps establish whether requirements grew or the original work was underestimated. The schedule baseline shows which dates are affected. Any additional spending is then assessed against the cost baseline; extra hours need the relevant cost rates to establish their financial impact.
The forecast reflects what the team now expects to need to finish. Keeping it separate from the project baseline preserves the difference between what was agreed and what now looks achievable. Approved changes update that reference, with earlier versions retained.
The Project Monitoring and Control Process
The project monitoring and control process establishes whether execution is drifting from the plan, explains the cause, and checks whether a response helped. These project monitoring steps repeat throughout delivery, with urgent changes reviewed before the next scheduled update.
1. Agreement on Measures and Decision Rules
The team confirms the project baseline and what counts as progress. A feature marked complete in development, for example, may still need testing before it can be accepted.
That agreement determines what the review measures and when a deviation needs attention. A small task overrun may wait for the weekly review; a blocked dependency affecting tomorrow’s release cannot.
2. Collection of Comparable Evidence
Project performance monitoring brings together records for the same work and reporting period. Without that consistency, completed tasks may appear alongside costs that have not yet been fully recorded.
The manager checks whether closed tickets still await acceptance and whether time logs or supplier costs are missing. Resolving those gaps makes the comparison reliable enough to investigate an apparent deviation.
3. Investigation of Deviations
Project monitoring and control methods help explain the difference between expected and actual progress. Comparing effort with estimates reveals where work took longer; reviewing requirements and dependencies helps establish why.
If repeated revisions account for the extra hours, the manager checks whether requirements changed or acceptance criteria remained unclear. That finding guides the response: additional capacity may accelerate work, but it will not resolve uncertainty about what the client expects.
4. Authorization and Implementation
The response needs an owner with access to whoever can approve it. A technical lead may adjust the implementation approach, while changes to fees or delivery commitments require commercial authority.
Where approval is needed, a change request records the proposed adjustment and its effect. Once authorized, the owner puts the decision into practice and updates the affected work, giving the next review a specific change to assess.
5. Review and Reassessment
The next review checks whether the response addressed the cause. If clearer acceptance criteria were intended to reduce rework, subsequent work should pass review with fewer avoidable revisions.
Project monitoring and controlling continues if that improvement does not appear. The concern remains open in the risk register, or the issue log if it has already occurred, while the owner reassesses the response and sets the next review point.

A verified risk still needs someone to act on it. See how Tolmete turns a delivery signal into a plan with an owner and a deadline.
Which KPIs Help Explain Delivery Health?
Key performance indicators (KPIs) help managers assess whether remaining work fits the agreed budget and schedule. Read together, they show which deviations need investigation.
Milestone forecast
Whether key dates remain achievable
Progress on critical dependencies
Actual cost plus estimated cost to finish
Whether completion fits the budget
Unrecorded costs and assumptions about remaining work
Effort against accepted work
How much effort produces an accepted deliverable
Work complexity and delays in acceptance
Requests awaiting scope approval
Potential growth beyond the agreement
Whether each request is already covered
Rework
Effort spent revising completed work
Planned iteration versus corrections caused by defects or unclear requirements
Earned value management (EVM) compares the budgeted value of completed work with actual cost and planned progress. The cost performance index (CPI) is earned value divided by actual cost; the schedule performance index (SPI) is earned value divided by planned value. Schedule variance is earned value minus planned value, measured in budget units, not days. These measures depend on reliable progress data. PMI explains the calculations.
Resource utilization shows how much capacity is occupied, but cannot establish project performance alone. A busy team may be correcting completed work while other deliverables wait.
Why a Green Dashboard Can Give False Reassurance
A dashboard can show completed tickets and milestones on schedule while the effort needed to finish keeps growing. If the report tracks activity without comparing it with remaining work, that increase may go unexplained.
A task with 36 hours logged, for example, needs context. If the estimate was 18 hours and the task remains open after repeated revisions, the manager has a reason to investigate. An approved addition might explain the difference; unresolved requirements might indicate that further rework is likely.
The hours are a metric. Their relationship with the estimate, revisions, and remaining work creates a signal. Checking that relationship helps the manager distinguish an expected change from a developing problem.
Lagging Indicators and Earlier Warning Signals
Lagging indicators show an outcome that has already occurred. Earlier signals reveal conditions that could lead to it. Monitoring and controlling in project management uses both to establish what has happened and where intervention may still help.
Budget exceeded
Repeated estimate overruns and rising completion forecasts
Milestone missed
An unresolved dependency threatens upcoming work
Margin reduced
Unpriced additions or avoidable rework consume the effort allowance
Client escalation
Unanswered decisions begin to affect commitments
Scope overrun
Requirements enter development without approval
The value of an early signal depends on its explanation. One task may exceed its estimate for a reason that does not affect the wider project. Similar overruns across comparable work suggest the remaining estimates may also need revision before the budget confirms the problem.
When the Deadline Holds, but the Effort Estimate Does Not
A fixed-price software project is planned for 12 weeks and 800 hours. In this illustrative scenario, the team has used 464 hours by the end of week five. Milestones remain on schedule, but repeated revisions and two extra requests raise concerns about what remains.
Spending 58% of the hours in 42% of the scheduled time does not prove an overrun; effort may have been concentrated early. The manager checks the original plan and asks the team to re-estimate unfinished work. The revised estimate shows another 390 hours are needed.
Forecast effort = hours used + estimated hours remaining
464 + 390 = 854 hours: 54 above the allowance
The deadline may still hold, but the extra effort needs a decision. New requests require agreement on scope and price; repeated corrections may require clearer acceptance criteria. The cause determines what can prevent the forecast from rising again.
Finding that cause takes more than the forecast. The manager needs to trace the extra hours to revised tasks and check whether the changes were approved. Those records may be spread across several tools, making the investigation difficult to repeat across every active project.
How AI Helps Connect Fragmented Evidence
Artificial intelligence (AI) can help managers investigate delivery risks by connecting requirements, recorded effort, and task history. Together, these records can explain why a forecast has changed, even when each tool still shows routine activity.
A reopened task, for example, becomes worth investigating when it also contains new requirements and hours beyond the original estimate. The manager needs to see when the requirements changed and whether the additional work was approved. Gathering that history is often what takes time before a decision can begin.
Delivery intelligence software helps assemble this context from existing project records. In Tolmete, evidence-based project signals connect a delivery concern with the activity behind it, giving the manager a specific change to examine. Its intelligent risk alerting considers the project context when recommending which concerns need attention.
The manager can then check whether the apparent deviation has an explanation, such as an approved addition, or calls for a response. That review remains necessary because the records may not contain the full agreement.
What Happens After the Risk Is Confirmed
Project management monitoring and control turns a verified concern into assigned work. In the example, the 54-hour forecast overrun needs an explanation. The technical lead identifies how much of it comes from the two new requests, which the client may be asked to fund, and how much from underestimating the original scope, which the client will not.
The delivery manager vs project manager distinction helps clarify who coordinates the response; authority to approve revised terms must also be explicit. Once agreement is reached, the project manager updates the affected work and sets a date to assess the result.
A proposed response is easier to review when it remains connected to the evidence behind it. Tolmete’s AI mitigation plans, for example, recommend actions, owners, and timing using delivery-signal context. Managers assess those recommendations, then check whether the agreed action brought the work within the revised commitment.
The Value of Monitoring Is the Time Left to Respond
A project can stay on schedule while becoming harder to finish within budget. Managers monitoring and controlling project management activities need to recognize that gap while they can still address it. Once the extra hours are spent, an explanation cannot recover them.
That makes the time between a warning and a decision a practical test for project monitoring tools. Tolmete, for example, brings delivery signals together with project reporting and proposed responses. When the findings require client input, automated client reporting helps explain the work behind the proposed change.
With that context, the client can decide whether to approve the additional cost or defer the work. The team then updates its plan to reflect the agreement. This gives managers a way to monitor and control project work against the revised commitment, reducing the risk that unpriced additions lead to agency margin leakage.

FAQ
Frequently Asked Questions
The project monitoring and control process compares execution with the approved plan, investigates deviations, and checks the effect of agreed responses. When a new requirement changes the forecast, the team assesses its impact and obtains approval before revising commitments. The next review checks whether the decision improved delivery.
Project monitoring covers accepted progress, remaining effort, costs, scope changes, and unresolved dependencies. Priorities depend on the agreement: in fixed-price work, repeated revisions can reduce margin even when deadlines hold. Comparing those revisions with approved requirements helps determine whether the team needs a scope decision or a technical correction.
Useful KPIs include milestone forecasts, expected completion cost, rework, and approval delays. Project performance monitoring may also use the cost performance index (CPI) and schedule performance index (SPI) where earned value is measured consistently. Together, these indicators help identify whether remaining work still fits the budget and schedule.
Monitoring and controlling in project management should follow the urgency of delivery decisions. Daily blocker checks and weekly forecast reviews provide a starting point, with costs reconciled as financial records become available. A critical dependency failure or material scope change needs assessment before the next report if waiting would limit the response.
Managers can connect repeated estimate overruns with scope changes and unresolved dependencies. Project management monitoring and control uses these patterns to identify concerns that isolated records may conceal. The manager then checks the cause and assigns a response while there is still time to adjust the work.
