Achievement rates: what they don’t tell you about project performance
Dashboards for development projects give a prominent place to achievement rates. Activity execution rates, budget commitment rates, disbursement rates, deliverable completion rates and activity coverage rates are among the first indicators reviewed in steering meetings. That place is legitimate: they are easy to calculate, simple to interpret, and offer a quick read of a project’s operational progress. But this readability creates a persistent confusion: a high achievement rate is not, on its own, a reflection of strong performance.
Within a results-based management (RBM) logic, performance is not reducible to how many activities were carried out. It is appreciated through the changes produced for beneficiaries, organizations or territories.
A project can therefore show an achievement rate above 95% while producing limited results. Conversely, a project that adapted its activities in response to a shift in context may show a lower rate while achieving greater impact. This paradox highlights an essential distinction in M&E: achievement rates measure what was executed, not the real performance of a project.
Understanding what these indicators measure, and what they don’t, is an essential step for building a monitoring system capable of effectively informing decisions.
What an achievement rate actually measures
An achievement rate is, above all, an execution indicator. It compares what was actually carried out against what had been planned for a given period or objective.
A few examples illustrate this logic:
- 85% of planned training sessions were delivered;
- 92% of the annual budget was executed;
- 78% of programmed infrastructure was built;
- 96% of scheduled data collection surveys were completed.
These indicators provide valuable information. They help appreciate a project’s operational progress, adherence to the calendar, use of resources, delivery of outputs, and the teams’ ability to implement the planned activities.
What they do not tell you is much about the effects actually produced. Are beneficiaries using the infrastructure that was built? Did the training sessions change professional practices? Did investments improve living conditions? Are the observed changes sustainable? Are the results achieved commensurate with the resources mobilized?
Put differently, achievement rates mostly describe what the project did, and much less what the project changed. This distinction corresponds to the now classic separation between outputs, outcomes and impacts, which structures most logical frameworks and modern M&E systems.
Why a high achievement rate doesn't guarantee performance
The main limit of achievement rates lies in their inability to appreciate the quality of the changes produced. Several situations illustrate this gap.
Activities are carried out but rarely used
A project may build all the planned infrastructure and reach a 100% achievement rate. Yet some of that infrastructure remains under-used because of staffing gaps, lack of maintenance or a poor fit with local needs. Execution is complete, but the value created remains limited.
Beneficiaries participate without changing their practices
In many capacity-building projects, indicators track the number of people trained. When all planned sessions are delivered, the project shows an excellent level of execution. That, however, does not mean participants actually apply the acquired knowledge in their professional practice. The real change expected remains unknown.
Resources are consumed without meaningful improvement
A fully executed budget is sometimes presented as an indicator of good performance. In reality, it only reflects a level of resource consumption. The real question remains: what results have those resources enabled?
Initial objectives become less relevant
Projects operate in environments where needs, public policies or socio-economic contexts can change rapidly. In such situations, systematically pursuing the activities initially planned only to preserve a high achievement rate can lead teams to maintain actions that have become less relevant. The project then optimizes its level of execution at the expense of its usefulness.
A project can optimize its achievement rate at the expense of its real usefulness.
Rural electrification program in West Africa:
when 100% execution masks limited use
A four-year regional electrification program, funded by a bilateral donor, planned the installation of 420 solar mini-grids across four Sahelian countries. At closure, the dashboard reported an achievement rate of 98%: 412 mini-grids actually installed, budget executed at 96%, all sites connected on schedule.
The final report presented the program as a success. An independent impact evaluation, conducted two years after closure, produced a radically different reading by documenting levels 02 through 04 of the results chain.
Of the 412 mini-grids installed, only 61% were still operational. The average household connection rate among targeted communities was capped at 38%, well below the 80% target. The main causes identified were the absence of a local maintenance system, a tariff structure unsuited to rural incomes, and beneficiaries’ limited familiarity with productive uses of electricity.
The M&E system had measured with precision what had been done, but nothing of what had been changed. Corrective decisions could have been taken as early as the second year had level 02 and 03 indicators been tracked alongside execution.
Why M&E systems favor execution indicators
If the limits of achievement rates are widely known, why do they still occupy such a prominent place in M&E systems?
The first explanation lies in data availability. Activities carried out naturally produce evidence: reports, attendance sheets, contracts, invoices, minutes or technical reports. This information is readily accessible and relatively straightforward to consolidate.
By contrast, measuring a behavioral change, an institutional improvement or a socio-economic effect requires surveys, repeated observations, qualitative methods and sometimes several years of monitoring.
Reporting requirements also reinforce this pattern. Periodic reports addressed to technical and financial partners are often organized around activity progress. Teams therefore concentrate their efforts on the information most immediately requested.
Finally, results rarely emerge at the same pace as activities. A training session can be organized in a few days, but its effects on professional practice may only become visible several months later. This difference in temporality explains why execution indicators often occupy a dominant place in dashboards.
This imbalance between what is produced and what is actually used to steer projects echoes a broader structural issue: the disconnect between data produced and decisions taken.
Consequences for steering and decision-making
A reading focused exclusively on achievement rates can progressively shape management decisions.
Project managers may be led to prioritize completing activities rather than pursuing the most useful results. Ineffective activities sometimes continue to be funded simply because they help maintain execution indicators.
This approach can also give an incomplete picture of performance. A high achievement rate may suggest that a project is fully meeting its objectives when the expected changes remain limited or insufficiently documented.
Lastly, this focus on execution weakens evaluations. When the monitoring system mainly documents activities carried out, evaluators have little information to analyze effectiveness, efficiency or sustainability. Much of the data must then be reconstructed a posteriori. This drift connects with the paradox of perfect M&E: a technically flawless system that documents without transforming.
Building a more balanced indicator system
Achievement rates should not be abandoned. They remain essential for tracking a project’s operational progress. But they gain from being complemented by indicators covering the full results chain.
A balanced monitoring system typically combines:
- Execution indicators, which track the delivery of activities;
- Output indicators, which measure the goods or services effectively delivered;
- Outcome indicators, which assess changes observed among beneficiaries;
- Impact indicators, which analyze economic, social, institutional or environmental transformations over the longer term.
This articulation produces a much more faithful reading of a project’s performance and helps avoid confusing volume of activities with value creation.
In this logic, digital M&E platforms play a structuring role. When they connect planning, activity execution, results indicators and decision dashboards in a single environment, they enable a much more complete analysis of performance.
Connect execution and results in a single steering environment
Delta Monitoring is designed to connect the 4 levels of the results chain in a single platform: activities, outputs, outcomes and impacts. Dashboards go beyond tracking achievement rates; they allow teams to see at a glance what has been done and what has been changed, bringing field data and strategic indicators together.
Toward a performance culture rooted in change
Achievement rates remain essential indicators. They make it possible to verify that planned activities are effectively implemented and that resources are mobilized according to plan. But they only make up part of the answer.
A truly results-oriented organization does not just ask whether its action plan was executed. It also seeks to understand to what extent that execution produced the expected changes.
Ultimately, the real question is no longer only:
“Did we do what was planned?”
but also:
“Did what was done actually produce the expected effects?“
It is precisely this shift that turns M&E into a genuine decision-support tool. Dashboards no longer serve only to measure activity progress; they become instruments of analysis, learning and strategic steering, capable of supporting organizations in the sustainable improvement of their projects’ performance.
