Track Your Agile Projects with a Project Burndown Chart

Agile project management often needs more than the practices provided as standard by agile methods. Tracking project status is one area where I think that’s true.

Scrum includes the concept of a Sprint Burndown Chart.  For those that aren’t familiar with it, it’s a simple yet very powerful concept. Here’s how it works…

At the start of each Sprint, the team has estimated the work they plan to complete in the Sprint, either in hours or in points.  The burndown chart has the days of the Sprint across the bottom axis.  On the first day of the Sprint, the number plotted on the chart is the total planned time or points for the Sprint.  Each day, this total is reduced for any items that are completed, so the total gradually reduces, hopefully until it reaches zero at the end of the Sprint.

You can also draw a target line from the top left of the chart to the bottom right, assuming that every day the same number of points or hours are ‘burnt down’.  If your actual line is below the target, you’re on track.  If it’s above, you’re falling behind.

And that’s the beauty of the burndown chart.  You can see very clearly – literally at a glance – how the team is doing against their Sprint plan.

Extreme Programming, by the way, has the same concept, but in XP you burn up rather than down.

So what’s a *Project* Burndown Chart?

Well it’s simple really…

It’s an adaptation of the Sprint burndown chart, designed to give you the same sort of clarity, but at a project level, rather than for an individual Sprint.

Use a similar format to the daily Sprint burndown chart, but instead of days along the bottom, put Sprints.  At the start of the chart, plot the total size of the Product Backlog for the entire project.  For your target line, reduce the number for each Sprint by your target or forecast Velocity (the number of points or hours you expect to burn down in each Sprint).  As you complete each Sprint, reduce your actual number by your Velocity and the actual line will start to come down, hopefully as fast as your target line!

Here’s an example of a project that hasn’t gone to plan:

Agile Project Burndown ChartAnd that’s it!  It’s as simple as that.

When you have a project that spans multiple Sprints, it can be hard to keep track of where you really are.  With a Project Burndown Chart, it’s easy.  And best of all, it hardly takes any time at all to produce and doesn’t require you to do any additional planning.

I’ve never seen a Gantt chart and traditional status report provide the same incredible clarity that a Project Burndown Chart does.  It’s brilliantly simple, and it’s quantitative, rather than a matter of opinion.

If you have multiple projects on the go, across several teams, there is no quicker way to know which projects are on track and which are struggling, and with a fraction of the paperwork and effort of a traditional PMO (Project Management Office).

  1. I recommend using a project burnup chart, instead. A project is not a known size. In fact, if you don’t learn something that alters the scope along the way, it’s arguably not an Agile project. We should always be learning.

    A burndown chart does not gracefully handle changes in the size of the work to be done. It’s got a natural fixed goal line at zero. If you leave this fixed, then changes in scope get displayed the same as work done (or undone).

    People have described burndowns where the goal moves away (generally below) zero, but I find a burnup to be simpler and more expressive of the uncertainty inherent at the beginning of a project.

    See Feel The Burn, Getting the Most out of Burn Charts from Better Software Magazine (July/August 2009, Volume 11, Issue 5, pp. 26-31) for some more detailed discussion on this. Also, Projecting into the Future for some tips on using a burnup to make predictions about your project in the face of incomplete information.

    Hey George,
    Thanks very much for taking the time to leave a link…..that was exactly the knowledge I need to get to the next step.:)

What People Say

“Kelly revolutionised the way our digital department operated. A true advocate of agile principles, he quickly improved internal communication within our teams and our internal clients by aligning our business and creating a much enhanced sense of transparency in the decisions the business was making. Kelly also introduced a higher sense of empowerment to the development teams...”

PETER SILVA-JANKOWSKI
IPC MEDIA

“Kelly’s a leading program director with the ability to take charge from day one and keep strong momentum at both a program and project level driving prioritisation, resourcing and budgeting agendas. Kelly operates with an easy-going style and possesses a strong facilitation skill set. From my 5 months experience working with Kelly, I would recommend Kelly to program manage large scale, complex, cross company change programs both from a business and IT perspective.”

LUKE SHARKEY /STRATEGY & IMPLEMENTATION LEADER
SUNCORP

“Kelly is an extremely talented and visionary leader. As such he manages to inspire all around him to achieve their best. He is passionate about agile and has a wealth of experience to bring to bear in this area. If you're 'lucky' he might even tell you all about his agile blog. Above all this, Kelly is great fun to work with. He is always relaxed and never gets stressed - and trust me, he had plenty of opportunity here! If you get the chance to work with Kelly, don't pass it up.”

GILES BENTLEY, DEVELOPMENT & OPERATIONS DIRECTOR
TIME INC

“Kelly is an Agile heavy-weight. He came in to assess my multi-million $ Agile development program which wasn’t delivering the right throughput. He interviewed most of the team and made some key recommendations that, when implemented, showed immediate results. I couldn’t ask for more than that except he’s a really nice guy as well.”

DAN PULHAM, DIGITAL DIRECTOR
TELSTRA

“Kelly and I worked together on a very large project trying to secure a new Insurer client. Kelly had fantastic commercial awareness as well as his technical expertise. Without him I would never had secured this client so I owe a lot to him. He is also a really great guy!”

GINA MILLARD

“Kelly came to the department and has really made a huge impact on how the department communicates, collaborates and generally gets things done. We were already developing in an agile way, but Kelly has brought us even more into alignment with agile and scrum best practices, being eager to share information and willing to work with us to change our processes rather than dictate how things must be done. He is highly knowledgable about agile development (as his active blog proves) but his blog won't show what a friendly and knowledgeable guy he is. I highly recommend Kelly to anyone looking for a CTO or a seminar on agile/scrum practices - you won't be disappointed!”

ANDY JEFFRIES/TECHNICAL LEAD
IPC MEDIA

“Kelly was a great colleague to work with - highly competent, trustworthy and generally a nice bloke.”

HANNAH JOYCE

“Kelly was engaged as a Program Director on a complex business and technology transformation program for Suncorp Commercial Insurance. Kelly drew on his key capabilities and depth of experience to bring together disparate parties in a harmonised way, ensuring the initiate and concept phases of the program were understood and well formulated. Excellent outcome in a very short time frame. ”
