At Lean Agile Scotland last weekend I was chatting with Gojko Adzic over dinner, and one of the many topics we covered was whether capability was the right word for one of the three impacts I describe as desirable with Kanban Thinking. Earlier this year I described what I meant by capability, but more recently I’ve realised capability is more commonly referenced as a property of the whole system, rather than one specific impact. In other words, if we improve a system’s flow, we have improved the system’s overall capability. Thus I needed to find a new word.
When I referred to capability as an impact, my goal was to ensure as much emphasis was placed on the people who are doing the work, as was on the work itself and its process. This emphasis is what enables a system’s performance to be sustainable over the long term, and even to improve over time. I had been toying with sustainability, but Gojko suggested the word potential and the more I think about it, the more I like it. Potential can be defined as the “possible, as opposed to the actual”, and what is “capable of being or becoming”. This clearly describes that improving a system’s potential is improving the long term future of that system.
Another way of looking at it is the metaphor of a pipe, again inspired by Gojko. If value is what comes out of the pipe, and flow is the progress through the pipe, potential is what can go into the pipe. A system which has a positive impact on potential is one which opens the tap to allow more to be done.
Then there is also the notion of human potential. Bob Marshall referred to this, and specifically to the waste of human potential, in his Lean Agile Scotland session on Rightshifting, further reinforcing the notion. I also noticed that Matt Wynne has referred to the same waste in his blog post following the conference. This has a nice synergy and helps reinforce the idea that increasing a system’s potential is not about cracking the whip harder. Rather it is about investing in people, unleashing their creativity, and making work fun.
As a result, the latest Kanban Thinking model now looks likes this.
