The mechanics

Here is the short version.There is no single setting for Hierarchical Model. It bends to the audience, the channels, and the wider plan.

Think of Hierarchical Model as context-bound. A small shop reads it simply; an enterprise reads it with more nuance. That is normal -- Hierarchical Model is shaped by audience and channel mix. Read Hierarchical Model without care and the plan wobbles; be precise and the read holds.

One rule always holds. Settle the scope of Hierarchical Model up front, then build the plan. Get it backwards and Hierarchical Model becomes a word everyone uses and no one shares. Here is the short version.

When teams use it

Worth a slow read.Use Hierarchical Model when it changes a choice. If it is not driving a decision, it is vocabulary, not leverage.

  3. Comparing options. Hierarchical Model stops a tidy-looking comparison from misleading.
