What is Project Forecasting?

Project forecasting predicts future project outcomes based on historical and current project data. It allows project managers and stakeholders to anticipate the likelihood of project success, identify potential risks and opportunities, and make informed decisions about resource allocation, budgeting, and scheduling. 

Forecasting is an iterative process that involves continually reviewing and updating project data to refine predictions and make adjustments as necessary. Project forecasting is a vital component of project management that enables organizations to stay on track and achieve project goals while minimizing risks and costs. 

What Metrics Would You Forecast for the Project?

There are several metrics or indicators that project forecasting considers, such as:

Project Duration 

Duration is one of the most critical metrics to forecast when planning a project. Forecasting the duration of a project allows stakeholders to determine how long it will take to complete and whether or not deadlines can be met. 

The duration of a project is usually estimated by looking at historical data and taking into account any external factors that could affect the timeline, such as weather, regulations, or market conditions. The duration can then be adjusted based on available resources and expected workloads for team members. 


Your project may involve many cost factors. It’s essential to accurately predict the total cost of a project before it begins, as this helps stakeholders make informed decisions about budgeting and resource allocation. 

The costs associated with a project may include:

  • Materials, 
  • Personnel labor, 
  • Equipment rental or purchase, 
  • Legal fees, 
  • Taxes and other expenses. 

When forecasting costs for a project, consider all potential factors that could affect the total cost and adjust them accordingly.

Resources Needed

Most projects involve personnel, equipment, materials, and other resources that must be accounted for when estimating duration and cost. 

When forecasting resource needs for a project, consider the personnel required to complete tasks or activities and any special training or certifications they may need. You should also factor in any additional material costs associated with completing the project. 

Finally, consider how long it will take to obtain any necessary equipment or supplies before beginning work on the project. 

Expected Quality Of Deliverables Or Outcomes  

While quality estimation may not be a straightforward metric to forecast, it is still essential for project success. Quality of deliverables or outcomes refers to the extent to which they meet the organization’s standards. 

When forecasting quality, consider factors such as the level of expertise required for each task, potential risks that could affect results, and external conditions that could impact delivery times or costs. 

Risks Associated With The Project 

Project forecasting also takes into account potential risks associated with the project. Risk analysis is a critical part of project management that helps identify and assess possible threats to the project’s success. 

By understanding the risks, stakeholders can develop strategies to mitigate or avoid them altogether, thus increasing the probability of success for the project. Examples of risks include factors such as natural disasters, technical issues, market conditions, personnel turnover, and budget constraints. 

Time Spent On Tasks Or Activities 

Before you begin your project, you should have a clear idea of how long each of your team members will spend on each task or activity. This will help you manage the project resources better and ensure that tasks are completed in a timely manner. It can also help you to adjust the project budget and timeline if need be.

Performance of Team Members 

While the performance of team members is not always easy to predict, it can be a valuable indicator of project success. Forecasting the performance of team members allows organizations to identify areas where individuals may need additional training or support in order to reach their goals. 

Forecasts can also inform decisions about staffing and task assignments by revealing which team members are best suited for particular tasks or activities. This helps ensure that project teams comprise the right people with the necessary skills and experience for successful completion. 

Project Forecasting Methods

Now that we know what metrics you should forecast for your project, let’s look at two of the methods you can use. 

Qualitative Forecasting

Qualitative forecasting methods rely on subjective judgments and expert opinions to predict future project outcomes. This type of forecasting is best used for projects in uncertain environments with limited data available, such as new product development or market research. 

Qualitative forecasting involves gathering input from stakeholders, customers, and team members to generate predictions based on their expertise and experience. Standard qualitative techniques include 

  • Delphi Method: This method involves a panel of experts answering questions about the project in an anonymous survey. The responses are then compiled and analyzed to create forecasts. 
  • Nominal Group Technique (NGT): NGT is similar to Delphi but involves participants working together to generate predictions.
  • Brainstorming: Brainstorming sessions with participation from all stakeholders can be used to generate ideas and forecasts for the project. 
  • Scenario Analysis: Scenario analysis involves examining possible futures based on current trends and conditions.
  • Forecast by Analogy: Forecasting by analogy uses similar past projects or situations to generate predictions about the current one.
  • Market Research: Market research surveys, interviews, and focus groups can provide valuable insights into customer needs, preferences, and behaviors that can help inform forecasting decisions.

Quantitative Forecasting

Quantitative forecasting is a data-driven approach that uses statistical models and historical data to predict future outcomes. This type of forecasting is best used for projects in stable environments with easily accessible data, such as software development or marketing campaigns. 

Standard quantitative forecasting methods include 

  • Trend analysis: Here, you identify trends in the data and extrapolate them to predict future outcomes. This is one of the most commonly used quantitative forecasting methods, as it is relatively straightforward and does not require complex statistical models. 
  • Break-even analysis: You will use this method to identify your project’s profitability point. This will help you determine when its revenues will offset the costs associated with a project.
  • Cost-benefit analysis: You compare the potential benefits and costs of different scenarios or decisions to select the most cost-effective path forward.

Project Forecasting Best Practices

Project forecasting should be a priority for any project manager or team leader. Here are some of the best practices to keep in mind when creating a forecast:

Create Several Forecasts with Varying Levels of Outcomes and Risks

When forecasting, it’s important to create multiple forecasts with different assumptions. This will help you understand possible outcomes and prioritize risks accordingly. It also provides a better insight into how changes in scope or timeline might affect your project. 

For example, you can create a baseline forecast based on your current data and assumptions, then create alternative forecasts that consider different levels of risk. This will give you a better understanding of how risks can impact your project and help you adjust accordingly. 

Use a Project Forecasting Software for Automation

Project forecasting software automates the process of gathering, analyzing, and visualizing data. It helps project managers collect real-time data from multiple sources and quickly generate forecasts with accurate results. 

A project forecasting solution will save you time and money by streamlining your analysis process. It also reduces errors due to manual calculations and provides insightful reports for better decision-making. 

Work with Real-time Data

Project forecasting is only as effective as the data it relies on. When possible, use real-time data to accurately picture your project’s progress and future prospects. This can include everything from customer feedback to employee performance metrics. 

Real-time data will give you a more complete view of your project and allow you to make better decisions about budgeting, scheduling, resource allocation, and other critical aspects. 

Have Contingency Plans and Resources

Whatever you plan, there will always be unexpected events and circumstances that can disrupt your project. That’s why it’s important to create contingency plans with resources in mind, so you can quickly adjust if things don’t go as expected.

Your contingency plan should include alternative strategies for the worst-case scenarios and identify potential risks before they become problems. This will ensure that you have a backup plan in place when something goes wrong and help you stay on track even if there are delays or other issues. 

Communicate to Stakeholders Clearly

Project forecasting is a team effort, and it’s important to keep stakeholders informed of progress and changes. Communicating the forecasts clearly will help everyone understand the potential risks and outcomes associated with the project. 

It’s also essential to provide detailed reports on the current state of the project, as well as any future assumptions or forecasts. This will ensure that everyone is on the same page when making decisions about resource allocation, budgeting, and scheduling. 

Track Performance as You Go

Finally, project forecasting is not a one-time event. It’s an ongoing process that involves regularly tracking performance and adjusting forecasts accordingly. Keeping track of your project’s progress will help you identify any potential risks or opportunities early on and make necessary changes to ensure success. This is something you can do effectively with project forecasting software.
