Prepare the decisions and responsibilities that make the workspace useful. Define the programme's scope, obtain management sponsorship, identify the business activities in scope and assign the people who will prepare, own and review the work.
The guides then help you agree impact and likelihood criteria and maintain the vocabulary used by assessments. Translate those choices into Business context, Databases, and the relevant Settings areas.
The expected outcome is an agreed way of working with clear criteria and accountable participants. Review it as the organisation changes and use the findings to improve the next assessment cycle.
