How To Determine The Right Size For Your Project Team — Tentamen Software Testing Blog


The last time we presented three types of organizations and how they affect project teams’ effectiveness. Today we talk about what could be the right size for your project team. This post is based on a remarkable book written by Johanna Rothman, Manage It!

Project Authority

Johanna starts with essential advice. There will always be somebody above your position. But for as a project manager, you should not wait for authority confirmation.

Act first, and ask for forgiveness later.

How Big

You must put team members inadequate management infrastructure. By doing that, your project could succeed even with a smaller amount of people. We can manage teams of up to nine people. After that number, the team naturally breaks into subteams. This means you will need leads to manage those subteams.

Number nine could differ for your organization. You should take it as a heuristic in determining your team size. Add people to the team, and when you notice that team dynamic is broken, that is your number!
