Understanding Data in Project Management

In project management, data comes in many forms, including time-critical work completion, budget spending, resource allocation, team performance, and stakeholder feedback. These data are usually collected via various tools and methodologies such as project management software, feedback surveys, time tracking tools, and financial records. The data collection process is a continuous one as it allows project managers to adjust course proactively.

Data Analysis Techniques in Project Management

There are various techniques project managers can employ to analyze data effectively. Depending on the project’s nature and the data types involved, some common techniques include:

  • Descriptive Analysis: This is an exploratory data analysis type that helps project managers understand what happened by interpreting the historical data. For example, analyzing past project timelines or completed tasks via a Gantt chart.
  • Diagnostic Analysis: This involves a more detailed examination of data to understand why something occurred. It often utilizes probability, regression models, and distribution analysis. For example, project managers can use this to find any project delays’ root causes.
  • Predictive Analysis: This technique uses statistical models and forecast techniques to understand the future. In project management, predictive analysis helps anticipate future obstacles or needs. For instance, estimated timelines and resource management would fall under this category.
  • Prescriptive Analysis: This type of data analysis uses optimization and simulation algorithms to advise on possible outcomes. Project managers can use this to identify the best plan of action, considering given parameters and constraints.

When properly analyzed, this data helps project managers identify risks earlier, manage resources more efficiently, streamline processes, manage the project scope, and make cost-effective decisions.

For example, suppose a project manager noticed that certain tasks consistently took longer to complete than initially estimated. They could use data analysis techniques to determine why this was the case. Was it because the tasks were more complex than anticipated? Or were the project team members assigned to these tasks under-skilled?

Using the findings, the project manager could then decide whether to provide additional training for these team members, hire additional resources, or adjust the project deadlines to accommodate the longer task completion times.

Data-Driven Decision Making in Project Management

Data-driven decision making (DDD) is a process where decisions are based on actual data rather than intuition or observation alone. This method helps project managers to be objective when making decisions. For example, if the data shows that a particular process is inefficient, it would be in the project’s best interest to refine or replace it, despite any personal biases towards keeping the process intact.

Moreover, data-driven decisions are often easier to defend to stakeholders or team members since data provides a concrete basis for the decision.

Consider a project where the initial plan was reliant on a particular resource. However, consistent delay patterns from this resource are highlighted in the collected data. In this case, a project manager can use data-driven decision-making to prompt a change of resource to correct the project course. This decision is objective, fair, and based on hard evidence, hence, easily acceptable by the project stakeholders.


In conclusion, the effective collection and analysis of data is crucial in making informed project decisions. It’s an essential component of any PMP’s skill set, helping to maximize efficiency, mitigate risk, and consistently deliver successful projects.
