Every project is a journey, and like all journeys, it’s less stressful when you know where you’re going. Project milestones are essential points of progress that help everyone involved understand what to expect, and a milestone chart helps visualize how these things will happen. You can use them to set goals for yourself and coworkers, and they’re helpful for making the project feel more doable.

In this article, we’ll take a closer look at project milestones and then walk you through creating your very first milestone chart.

What are project milestones?

A project milestone is a significant point or event in the project timeline. It marks an achievement or the completion of a critical phase in the project. For example, if you’re planning a wedding, it’s traditional to have a few milestones along the way:

  • Choosing your venue and caterer
  • Hiring a photographer
  • Receiving your marriage license from the county clerk’s office, and so on.

In a work context, project milestones keep the team on the same page and working toward the same goal. It’s important for everyone to understand where they fit into the process and what’s expected of them at each stage. Here are some examples of typical project milestones:

  • Meetings
  • Team roles and responsibilities assignments
  • Sign-offs
  • Approvals
  • Beginnings of different tests
  • Phase completions

These activities relate to the deliverables you want at the end of each phase. Milestones usually come at the end of each phase, but not always. They can serve as checkpoints at any point to see if the project is ahead of schedule, behind schedule, or right on track.

What is a project milestone chart?

A project milestone chart is a tool that shows how your milestones relate to one another. It can include due dates and other relevant information, helping you visualize the sequence and interdependence of milestones. If something unexpected happens, the chart helps you identify who needs to address the issue and where the problem occurred so you can fix it and continue with your project.

Benefits of milestone charts

Project milestone charts help you visualize how milestones work together to achieve the project outcome. This visualization offers numerous benefits to the project and its team members.

Better decision-making

Milestone charts mark progress toward the end goal and show how far along each phase is. Managers can use this information to make informed decisions about what should happen next to keep the project on track.

For example, if your milestone chart shows a delay due to missing key materials or resources, the manager might decide to extend the deadline for that part of the project, allowing everything to come together smoothly.

More accurate financial forecasting

Recording milestones on the chart helps managers clearly value what has been achieved and what still needs to be done. This information is essential for making decisions about extending deadlines and showing investors where their money is going and the return they are getting on their investment.

Investors typically want to see clearly defined milestones with attached values and an estimated schedule for when these milestones will be met.

Clearer task prioritization

Project milestones help the team focus by marking the end of specific sub-phases, allowing the team to shift their focus to new goals without worrying about the previous steps.

Improved accountability

Milestone charts clarify team members’ responsibilities and deadlines, ensuring everyone knows what they need to do and by when.

Better time management

Clearly defined milestones help keep the project on track by setting clear expectations for what needs to be done and when.

Enhanced transparency

Stakeholders can see progress and understand the project’s status. Milestone charts make it clear what needs to be done, how much time it will take, and the dependencies of other milestones.

Increased team motivation

Achieving milestones provides a sense of accomplishment, motivating the team to continue working towards the next goal.

Better collaboration

Milestone charts clarify each step’s status and dependencies, which is especially useful when different individuals work on separate parts of the project. This clarity enhances collaboration and ensures everyone is aligned and working towards the same objectives.

Choosing the right tool to build your milestone chart

Selecting the right tool to create your milestone chart is crucial for the efficiency and success of your project. There are several factors to consider when making this choice, including ease of use, functionality, integration capabilities, and cost.

How to create a milestone chart

Creating a milestone chart is easy with the right tools. And it just takes three steps:

  1. Planning milestones
  2. Creating a milestone chart
  3. Sharing it your team and stakeholders

Let’s unpack these in a little more detail.

Step 1: Planning milestones

Project planning is no different than any other type of planning. The first step is to brainstorm all milestones you can think of at the top level (mind mapping can come in handy here).


  • Tasks marking the beginning or end of a phase
  • Critical tasks
  • Tasks or phases needing stakeholder approval

Once you’ve listed these down, it’s time to arrange them into a timeline and determine the lead time between milestones. This is where a template like a project timeline or Gantt chart comes in handy.

Step 2: Creating a milestone chart

Milestones are placed on the chart according to their scheduled or projected completion time, starting with the earliest milestone.
