Segmentation
Segmentation organizes a population into groups useful for a decision or action. It can be based on usage, potential, needs, or history. A segment must lead to a justifiable and understandable action. Multiplying groups without associated actions complicates management without any clear benefit.
A concrete example
A programme distinguishes between new members, regular buyers, and inactive customers. Each segment receives a tailored proposal and success measure.
A point to consider
A segment must trigger a different action. Accumulating categories without operational use complicates management.
Link each group to a decision.
For each segment, indicate the entry criterion, the need, the proposed action, and the exit condition. Verify that the data enabling this allocation is available and up-to-date. Limit the number of groups to what the team can realistically manage. A participant moving between segments must maintain a consistent learning path, particularly regarding previously announced objectives and acquired benefits.
Questions to ask your team
- What decision would be different if this segment did not exist?
- How often are members reassigned?
