It’s completely normal not to know all the details at the beginning and not to fill in every field in the teamdecoder tools right away. It would actually overwhelm the team to try and think everything through from the start.
In the first sessions with the team, focus on the basic structure, which roles and which groups need to exist.
That means at the beginning, a role or a group might just have a name. If it’s brand new, maybe a purpose too, since this can help spark the question, “Why exactly do we need this?”.
If a discussion comes up about how this new role or group differs from others, you might jot down one or two tasks, but this is not the time to launch into a full brainstorming session to define every detail of a role or group.
Later, in follow-up workshops (ideally in smaller groups) you can work on the details and gather input for each field.
Experience shows this usually happens naturally over time. At first, no one feels like listing tasks that seem “obvious.” But later, when it becomes clear that things might not be so obvious after all, people are more motivated to clarify.
So: take your time!
Start with the big picture, then gradually work your way into the details. Always focus on what helps the team gain clarity in the moment.
