Getting Teams to Deliver Predictably

queue size compared to utilization

As recently as this week, I’ve been involved in conversations with customers about how we can help make their teams deliver more predictably.  How can they meet commitments on all levels of the organization, including project, program, and portfolio?

Well, it’s not easy.  There is no silver bullet that is going to allow you to align the organization overnight.  I do, however, have one recommendation:  Stop trying to maximize the utilization of your people.  I know some are going to find that hard to understand.  To maximize value throughput, you need to keep your people as busy as possible, right?  Didn’t Henry Ford do it that way, when he had cars coming off the assembly line at three-minute intervals?  Actually, no, he did not.  What he had and what you need is a balanced system.

Henry Ford did not have everyone working at 100% utilization.  If everyone worked at 100%, the result would have been congestion — bottlenecks within his (assembly) system and the production of excessive parts inventory.  Instead, one of the many things he did was focus on limiting lead times.  That’s the time something waits before an activity happens.  By understanding his system, he was able to have the right amount of people, working at the right pace, in the right sequence, in order to maximize flow (delivery through the system).

When trying to get your teams to delivery predictably at your organization, let’s look at this from a 100,000 foot view:

  • Understand Current and Potential Capability and Capacity
  • Understand the Delivery System and Establish Goals
  • Balance Capacity and Capability with delivery throughput
  • Monitor Performance

That is how you establish predictable outcomes.

Now let’s look at this with some detail.

Understand Current and Potential Capability and Capacity

You’ve probably heard the analogy of a freeway being a value delivery system.  If not, let me draw the parallels.  On a freeway, we don’t care about utilization; we care about throughput. That is, we don’t care how many vehicles can fit onto the freeway. We care how quickly we get from point A to point B.  Measuring the capacity of the freeway is not going to directly help us. Measuring the throughput will.  For those who follow Lean Startup, these are referred to as vanity metrics and actionable metrics.

Actionable metrics can lead to informed decisions and subsequent action.  Example, I know how fast the vehicles travel on a given freeway, therefore I can plan accordingly to arrive on time.  Vanity metrics show that you’re measuring things, but they really aren’t helping you. You need to measure the right things.  By measuring the capacity of a freeway and then trying to fully utilize it would be foolish.  Strangely enough, I see organizations do that with their people all the time.  They try to keep them as busy as possible.

Understand the Delivery System and Establish Goals

We don’t build bigger freeways so they can hold more vehicles.  We build bigger freeways because we’re not smart enough to figure out how to limit the size or amount of vehicles on them at the same time.  The fewer or smaller the vehicles on the highway at the same time, the faster everyone moves along.  To increase throughput (speed) on a freeway, you need to increase the ratio of space utilized by a vehicle relative to the total space of the freeway.  If we could increase the (distance) buffers between the vehicles, we’d have fewer start and stops along our commutes. Once we hit higher utilization rates, things dramatically slow down until we have traffic jams.

Balance Capacity and Capability with delivery throughput

It’s the same thing with knowledge based systems!  Exceed a 70% utilization rate and you’ll begin to see dramatic performance decreases.

One thing that I have seen that is bringing it together is enabling teams to make their own commitments.  Once they have a sequenced queue of work and all the people necessary to complete that work, allow them to commit to, start, and then finish it.  You should begin to see the flow of value start to emerge.  Don’t pull people from the team to give them “busy” work.  Don’t push extra work on the team to keep them busy.

Monitor Performance

You can tell if your people are over-utilized by measuring the lead times.  If their work is properly sequenced, and they limit the size and volume of work they agree to do at any given time, the result should be minimal delays.  If you want to go faster, you may have to change the system.  Measure how long it takes to get something through your system.  Reflect on that.  Were there any dependencies on other people or resources that slowed you down?  Did you have your people over-utilized?  Was the work you committed to too big?  Look for an area of possible improvement, address it, and run work through your system again.  Did the lead time get shorter?

Going back to the commuting analogy, for those doing the driving, understand the conditions and know the optimal start time to begin your commute in order to avoid delays and arrive at your destination without breaking any laws.  For those asking for arrival commitments, respect what the driver tells you.  If you don’t, you’ll find people doing things like driving on the shoulder or illegally speeding in the express lane, just to arrive on time.  Sooner or later, there’s going to be an accident.

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...”


“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.”


“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.”


“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.”


“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!”


“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!”


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


“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. ”


“I worked with Kelly on many projects at IPC and I was always impressed with his approach to all of them, always ensuring the most commercially viable route was taken. He is great at managing relationships and it was always a pleasure working with him.”


“I worked with Kelly whilst at Thoughtworks and found him to be a most inspiring individual, his common-sense approach coupled with a deep understanding of Agile and business makes him an invaluable asset to any organisation. I can't recommend Kelly enough.”


“Kelly was a brilliant CTO and a great support to me in the time we worked together. I owe Kelly a great deal in terms of direction and how to get things done under sometimes difficult circumstances. Thanks Kelly.”
