Lean and Super7 Operations work with small, autonomous teams. Exactly how small should our small autonomous teams be?
This is the question the manager of the central back-office of a large Dutch retail bank asked me, when I proposed the idea of autonomous team to him. At the time, I was working on a project to introduce customer focus and to realise same-day processing in his organisation. I came up with an innovative organisation design, in which small teams are responsible for their work for that day, i.e. all customer request of a certain type that the bank had received that day. After successful pilots, the organisation wanted to introduce this way of working for all (ca. 400) employees. That’s when this question came up…
From experience, I knew that the teams shouldn’t be too big: the pilots were done with teams of 5 – 7 persons. However, factual substantiation was needed. A quick search showed me that a lot of research had been done on Agile / Scrum teams, so that’s where I started. And this article is the result: a literature search on the optimal team size for autonomous teams.
My conclusion is: Organisational design isn’t an exact science. As an engineer, I would have loved to have found statistically sound measurements on the effectiveness of teams of different sizes – but in truth, I think that team size isn’t the main driver for team effectiveness. However, if your customer, the type of work your customer asks you to do, requires your organisation to work in small teams, I would suggest – as I did to the manager of the banking back office: small teams consist of 5 to 9 persons. Or, If the flexibility of your workforce allows this, as it did in the case of the banking back office: flexible team size, ranging from 5 on slow days to 9 on a busy day.
At the moment of writing, the banking back office has implemented the new way of working, and has asked me to do a ‘check-up’ on effectiveness of the new organisation. I can’t wait to start: Ï wonder what I will find, but I bet that it will be inspiration for several articles on CoOperationalExcellence.nl!
