Is your team larger than 10 people? If so it is too big.

An ideal team size is between 3 and 10 members. This is true for all teams but especially for Executive Teams. When teams are larger than 10 members, meetings become less effective, time is wasted seeking consensus and the necessary conflict and spirited discussion required to generate real clarity is hard to have – all leading to important decisions failing to be made and windows of opportunity closing.

An Executive Team we worked with found it very difficult to make the hard decisions about team size and membership. At one point there were between 15 and 18 people on the top team.

The CEO thought that including everyone was a great developmental opportunity and it would improve morale amongst his leaders. He also thought it would help with communication, increase buy-in and speed up execution from the next layer of leaders. The result was the exact opposite.

Meeting times doubled.

There were just so many opinions to be heard and considered that team meetings became protracted and laborious. Members quickly became disillusioned with the ineffective meetings and team structure.

Then they fell into the consensus trap.

With the large group size making firm decisions became almost impossible and instead of getting buy-in, members started checking out. Soon team members only paid attention in meetings when a topic relating to their business area was being discussed. The rest of the time it was screens up and masks on.

Frustration grew.

This CEO feared conflict – deep down he wanted to be liked, especially by the people he was leading and he hardly ever forced clarity or closure on issues. He preferred to take the popular route and so deadlocks were never broken for fear of upsetting people. A fear of conflict was also one of the main reasons why this company’s team size issue had never been resolved. He simply did not want to alienate or disappoint people around him and so uncomfortable decisions were never made.

On a smaller team people are expected to weigh in and contribute … there are no places to hide. Issues can really be discussed. Now the lively debate and conflict that’s essential to gaining commitment can occur without worrying about its effect on the perceptions of others (we will talk about healthy conflict in August’s blog post). You can make sure that all points of view are thoroughly aired but also that decisions get made without being bogged down by consensus.

In the end, this turned out to be a great learning experience for the CEO. Ironically trying to be inclusive, at the wrong time, coupled with the need to be popular ultimately hurt the credibility of his leadership team and his organisation’s ability to produce results. He discovered that the next layer of leaders were looking for the Executive Team to lead, which meant having the difficult conversations at the top before communicating to the wider business. They needed the top team to clarify their thinking first before coming to them.

This did not mean they didn’t want to be consulted, but they did not expect to do the thinking for the Executives or get entangled in issues and dynamics that the top team had been unable or unwilling to resolve for themselves.

In the end his biggest lesson was that team size and membership is a critical issue for the productivity of the entire business as a whole.

Reducing the size of a team can be difficult. But how much is it worth to your company to be able to make important decisions quickly, to not miss out on important opportunities and to get unqualified commitment from your Executive Team members when communicating and executing those decisions?
