Using Milestones for Happier Project Scheduling

Project milestones are any fixed points in time that are worth flagging to help you keep the project moving forward and best communicate with your team. Proper project management tools and software have ways of defining and demonstrating key project milestones as a way of formalizing these on your project schedule.

Diamonds are a Manager’s Best Friend

The conventional icon for displaying a milestone on your project Gantt chart is a diamond. To add one, you simply select the task on your schedule and change the properties to turn it into a milestone. In some tools, you might see the date written next to it. Within your project plans in, if you hover over the diamond, you can see the name of the milestone, too. You can see this example more clearly in this support video.

The diamond shape makes it really easy to identify milestones when you are scanning through your project plan. That way you don’t have the check the task duration or go into each task to read the detail.

How to Use Milestones

Milestones act as convenient reminders of key dates in your project. These could include:

  • Project Board meetings
  • Other significant meetings like requirements workshops, especially if these are fixed in time because it has been difficult to get everyone together
  • Deadlines for completing components of the project
  • Deliverables due from other projects
  • Deliveries from suppliers
  • Turning points in the project where you transition to another state or phase.

You can link tasks to milestones, too. This is handy when you want to use the milestone at the end of one phase to kick off the start of the next. Just make the milestone the predecessor task of the next one in the series and everything will hang off that.

Keep your milestone names really descriptive. Avoid jargon or acronyms or phrases like “Milestone 1.” Stick to simple language that your whole team and the senior managers will understand like “Testing complete” or “Phase 2 begins.”

Celebrate Achievements

Another great reason to use milestones is that they flag up when the team has achieved something. You’ve completed a phase, or delivered a key part of the project. That’s worth celebrating!

Send a short note to the team when you hit a milestone on time, thanking them for their cooperation and work to get you to this point. Little notes like this help build good working relationships within the team and keep morale high while you forge forward.

At the end of your project you can use a milestone to point out when you are having your launch party and project closure celebration. It’s something to look forward to and having it marked clearly on your plan will make sure you don’t rush past on to the next project and forget to do it!

Using Milestones for Tracking

Milestones are a good way of helping other people understand how your project is moving forward, even if they don’t understand any of the detailed tasks. You can track progress by looking at how many milestones you have hit on time. It’s a basic measure of project status but it’s something that project stakeholders like because they don’t have to look at all the detail on your plan.

They can help you manage stakeholders’ expectations by putting them in the schedule at key points – times in the project that they care about, such as sign off of the design brief or the end of testing.

Include the milestones achieved this month and the milestones due next month on your project reports or in presentations. It’s also a good idea to highlight whether they were achieved on time, early or late and by how much. This gives everyone a clear idea of whether overall the project is progressing to plan and if not, what the impact has been. It’s unlikely your project sponsor will worry too much over a day but if you have missed your last milestone by a month then it’s time for the Project Board to step in and assess the project’s progress in more detail.

So What if I Don’t Like Diamonds?

You don’t have to use milestones on your project schedule. You could simply list all the tasks in a To Do list and work through them until the end. This might work for a small project but the risk on larger projects is that your plan becomes unmanageable and hard to read.

Milestones help break up the work into manageable chunks so that you can spot the natural breaks in the project. They remind you of critical dates and they act as a great communication tool.

If you’re curious about what to track as milestones on your projects, project management trainer Devin Deen offers some ideas in this short video: “5 Things You Need to Monitor on Projects.”

PMaspire thank you so much.
Brilliant way among all.

Excellent.. . thanks a lot to PMaspire. I have failed two times and I succeeded in the final attempt. This is the best Simulator

I am pleased to share my experience using the PMAspire resource. I accidentally stumbled on PMAspire, and took to it. The free trial opened up a lot of my weaknesses and I had to subscribe since I was preparing for my PMP Exam. The resource proved highly highly invaluable. It's to me a one-stop online shop. This is my experience. I painstakingly tested myself using the Knowledeg area questions and those of the Processes. It exposed my gaps, which I had to work on seriously. There were times of discouragement but I was undaunted as per my knowledge gaps and Gbam! I MADE IT. I GOT MY PMP! I will always reference and recommend PMAspire to anyone who wishes to sit for the PMP certification exam. I am right away recommending this to my colleagues in my office.
Thank you PMAspire for such a resource you offer for the exam preparation, it is very useful. It is a one-stop shop. The questions I encountered in my preparation using PMAspire resource helped shape my mind and helped me in the real exam. No regrets at all. I recommend PMAspire to potential candidates. Kudos and keep up the good job
