Synthetic research in the language of the decision.
A sector becomes useful when its decisions, actors, and vocabulary are visible. HDTwin begins with Cultural Institutions and follows the questions around audiences, programming, access, participation, and the relationship between an institution and its territory.

Begin with the sector
The initial published vertical is Cultural Institutions. It covers orchestras, theatres, festivals, museums, and the teams responsible for programming, audiences, communication, and territory.
Then name the decision context
Music & Performing Arts is the first application context inside this vertical, not a separate route or taxonomy.
Discuss a sector-specific question
30-minute online conversation; bring the decision, audience, and sector context; next step is a vertical walkthrough.
