Attention all business leaders, project managers, and PMO enthusiasts! If you're passionate about making your projects successful, implementing the right strategies and leveraging technology can make all the difference. Project evaluation is the process you need to comprehend and measure that success.

Keep in mind, though, evaluating a project's success is more complex than it may appear. There are numerous factors to consider, which can differ from one project to another.

In this article, we'll walk you through the fundamentals of an effective project evaluation process and share insights on measuring success for any project. With this information, you'll be well-prepared to assess if a project has met its intended goals, allowing you to make informed decisions and set benchmarks for future endeavors.

Let's get started on the path to successful project evaluation!

What is project evaluation?

Project evaluation is all about objectively examining the success or effectiveness of a project once it's completed.

Remember that each project has unique goals and objectives, so each evaluation will differ. The assessment typically measures how well the project has met its objectives and goals. Throughout the evaluation process, you'll need to consider various factors, such as:

  • Cost
  • Timeline
  • Quality of deliverables
  • Customer satisfaction

These factors help determine whether a project can be considered successful or not. It's crucial to remember that evaluation should happen continuously during the project, not just at the end. This approach allows teams to make informed decisions and adjust their course if necessary.

A practical evaluation process not only pinpoints areas for improvement but also celebrates the project's successes. By analyzing project performance and harnessing the insights gained through project evaluation, organizations, and project leaders can fine-tune their strategies to boost project outcomes and make the most of their investment in time, money, and resources for the project or initiative.

What are the steps for measuring the success of a project?

Measuring the success of a project largely depends on its desired outcomes. Since different projects have varying goals, their criteria for success will also differ.

For instance, a team launching a new product might measure success based on customer engagement, sales figures, and reviews, while a team organizing an event may assess success through ticket sales and attendee feedback. Even projects with similar objectives can have different measurements of success. So, there's no one-size-fits-all approach to evaluating project results; each assessment should be customized to the specific goals in mind.

In general, the process of measuring the success of any project includes the following steps:

1. Define the purpose and goals of the project

Before measuring its success, you need a clear understanding of its objectives, scope, and timeline. Collaborate with your team and stakeholders to establish these elements, ensuring everyone is aligned.

A well-defined project scope helps you set realistic expectations, allocate resources efficiently, and monitor progress effectively.

2. Assess the current status of the project

Regularly examine the project's progress in relation to its goals, timeline, and budget. This step enables you to identify potential issues early and make necessary adjustments. Maintaining open communication with your team and stakeholders during this phase is crucial for staying on track and addressing any concerns.

3. Analyze the results achieved by the project so far

Continuously evaluate your project's performance by looking at the results you've achieved against your goals. Organize retrospectives with your team to discuss what has worked well, what could be improved, and any lessons learned.

Use this feedback to inform your decision-making process and fine-tune your approach moving forward.

4. Identify any risks associated with the project

Proactively identify and document any potential issues affecting your project's success.

Develop a risk management plan that includes strategies for mitigating or transferring these risks. Regularly review and update this plan as the project progresses, and communicate any changes to your team and stakeholders.

Effective risk management helps minimize surprises and allows you to adapt to unforeseen challenges.

5. Establish KPIs (key performance indicators) to measure success

KPIs are quantifiable metrics that help you assess whether your project is on track to achieve its goals. Work with your project team, stakeholders, and sponsor to identify KPIs that accurately reflect the project's success. Ensure these metrics align with the project's purpose and goals and are meaningful to your organization.

Examples of KPIs include the number of leads generated, customer satisfaction scores, or cost savings.

6. Monitor these KPIs over time to gauge performance

Once you've established your project-specific KPIs, track them throughout the project's duration. Regular monitoring helps you stay informed about your project's performance, identify trends, and make data-driven decisions.

If your KPIs show that your project is deviating from its goals, revisit the previous steps to assess the current status, analyze the results, and manage risks. Repeat this process as needed until the project is complete.

15 project management metrics that matter

To effectively measure success and progress, it's essential to focus on the metrics that matter. These metrics vary depending on the organization, team, or project, but some common ones include project completion rate, budget utilization, and stakeholder satisfaction.

We have divided these metrics into waterfall projects (predictive) and agile projects (adaptive). While some metrics may apply to both types of projects, this categorization ensures a more tailored approach to evaluation. Remember that these metrics assume a project has a solid plan or a known backlog to work against, as measuring progress relies on comparing actual outcomes to planned outcomes.

Waterfall project management metrics (predictive)

Waterfall projects typically have a defined scope, schedule, and cost at the outset. If changes are required during project execution, the project manager returns to the planning phase to determine a new plan and expectations across scope, schedule, and cost (commonly called the iron triangle).

Here are eight waterfall metrics:

1. Schedule variance (SV) - Schedule variance is the difference between the work planned and completed at a given time. It helps project managers understand whether the project is on track, ahead, or behind schedule. A positive SV indicates that the project is ahead of schedule, while a negative SV suggests that the project is behind schedule. Monitoring this metric throughout the project allows teams to identify potential bottlenecks and make necessary adjustments to meet deadlines.

2. Actual cost (AC): Actual cost represents the total amount of money spent on a project up to a specific point in time. It includes all expenses related to the project, such as personnel costs, material costs, and equipment costs. Keeping track of the actual cost is crucial for managing the project budget and ensuring it stays within the allocated funds. Comparing actual cost to the planned budget can provide insights into the project's financial performance and areas where cost-saving measures may be needed.

3. Cost variance (CV): Cost variance is the difference between a project's expected and actual costs. A positive CV indicates that the project is under budget, while a negative CV suggests that the project is over budget. Monitoring cost variance helps project managers identify areas where the project may be overspending and implement corrective actions to prevent further cost overruns.

4. Planned value (PV): Planned value is the estimated value of the work that should have been completed by a specific point in time. It is a valuable metric for comparing the project's progress against the original plan. PV calculates other vital metrics, such as earned value (EV) and schedule performance index (SPI).

5. Earned value (EV): Earned value is a measure of the progress made on a project, represented by the portion of the total budget earned by completing work on the project up to this point. EV can be calculated by multiplying the percentage complete by the total budget. Monitoring earned value helps project managers assess whether the project is progressing as planned and whether any corrective actions are needed to get the project back on track.

6. Schedule performance index (SPI): The schedule performance index measures how efficiently a project team completes work relative to the amount of work planned. SPI is calculated by dividing the earned value (EV) by the planned value (PV). An SPI of 1.0 indicates that the project is on schedule, while an SPI of less than 1.0 means that the project is behind schedule. This metric helps identify scheduling issues and make adjustments to improve efficiency and meet deadlines.

7. Cost performance index (CPI): The cost performance index measures how efficient a project team is in completing work relative to the amount of money budgeted. CPI is calculated by dividing the earned value (EV) by the actual cost (AC). A CPI of 1.0 indicates that the project is on budget, while a CPI of less than 1.0 shows that the project is over budget. Monitoring CPI can help project managers identify areas where costs can be reduced and improve overall project financial performance.

8. Estimate at completion (EAC): Estimate at completion is an updated total cost estimation after the project is completed. EAC can be calculated using several methods, including bottom-up estimating, top-down estimating, analogous estimating, and parametric estimating. Regularly updating the EAC helps project managers stay informed about the project's financial performance and make informed decisions about resource allocation and cost control.

Agile project management metrics (adaptive)

Agile projects differ from waterfall projects as they often start without a clear final destination, allowing for changes along the way.

It's generally not appropriate to use waterfall metrics to evaluate agile projects. Each project is unique and should be assessed based on its purpose, objectives, and methodology.

Here are seven standard agile metrics:

  1. Story points: Story points are used to estimate the workload required to complete a task, taking into account the time, effort, and risk involved. Different teams may use various scales for measuring story points, so comparing story points between teams is not advisable, as it may lead to misleading conclusions.
  2. Velocity: This metric represents the work a team can complete within a specific period, measured in story points. Velocity helps gauge a team's progress, predicting the amount of work that can be completed in future sprints and estimating the number of sprints needed to finish the known product backlog. Since story points are not standardized, comparing teams or projects based on story points or velocity is not appropriate.
  3. Burndown charts: Burndown charts are graphical representations used to track the progress of an agile development cycle. These charts show the amount of known and estimated work remaining over time, counting down toward completion. They can help identify trends and predict when a project will likely be finished based on the team's velocity.
  4. Cumulative flow diagrams: These graphs, related to burndown charts, track the progress of an agile development cycle by showing the amount of work remaining to be done over time, counting up. Cumulative flow diagrams (CFDs) can help identify trends and predict when a project will likely be completed based on the team's velocity.
  5. Lead time: Lead time is the duration between the identification of a task and its completion. It is commonly used in agile project management to assess a team's progress and predict how much work can be completed in future sprints. Lead time is a standard Kanban metric, as Kanban focuses on promptly completing tasks and finishing ongoing work before starting new tasks.
  6. Cycle time: Cycle time is when it takes to complete a task once it has been identified and work begins, not including any waiting time before the job is initiated. Cycle time is frequently used in agile project management to evaluate a team's progress and predict how much work can be completed in future iterations.
  7. Defect density: As a crucial measure of quality and long-term success, defect density is the number of defects per unit of code or delivered output. It is often employed in software development to assess code quality and pinpoint areas needing improvement. If a team provides the output with a high defect density, the quality of the project's deliverables and outcomes may be significantly compromised.

Not all metrics are created equal

It's essential to recognize that not every metric suits every project. Project metrics shouldn't be seen as a one-size-fits-all approach.

With so many metrics, it can be easy to feel overwhelmed, but the key is to focus on the specific metrics that significantly impact your project's outcome. Project managers can make informed, strategic decisions to drive success by measuring the right aspects.

Your choice of project metrics will depend on various factors, such as the type of project, its purpose, and the desired outcomes. Be cautious about using the wrong metrics to measure your project's progress, which can lead to unintended consequences. After all, you get what you measure, and if you measure incorrectly, you might not achieve the results you're aiming for!

Tips on communicating metrics and learnings

Clear communication is crucial to ensure that insightful metrics and learnings have a meaningful impact on your team. To keep your team members engaged and your communications effective, consider the following tips:

  • Use straightforward, informative language: Opt for concise, easily understood language to ensure everyone has a clear grasp of the data and its implications.
  • Avoid abbreviations: Use full terms to avoid confusion, particularly for new team members.
  • Tell a story: Present metrics and learnings within a narrative context, helping team members better understand the project's journey.
  • Use humor and wit: Lighten the mood with humor to make your points more memorable and relatable while ensuring your message is taken seriously.
  • Be transparent: Foster trust by being open and honest about project progress, encouraging collaboration, and being the first to inform stakeholders if something goes wrong.

By incorporating these friendly and informative communication techniques, you can effectively engage your team members and maintain a united front throughout your project.

Cracking the code on project evaluation success

Project evaluation is a vital component of the project management process. To make informed, decisive decisions, project managers need a thorough understanding of various metrics aligned with the project's purpose and desired outcomes.

Effective teams utilize multiple metrics to assess the success or failure of a project. Establishing key metrics and delving into their implications allows teams to base their decisions on accurate, relevant information. Remember, one size doesn't fit all. Tailor success metrics to the specific goals of your project.

By implementing a robust evaluation process and leveraging insights, project leaders can adapt strategies, enhance project outcomes, maximize the value of investments, and make data-driven decisions for upcoming projects.
