Shared clarity is a critical part of any problem solving process. Only when all the stakeholders see the (same) forest can we move on in sync to create the appropriate deliverables.
Strategic design processes understanding, knowledge, and ideas to arrive at a point of clarity. Subsequent executional work is then built on top of this clarity to maximise the chance for a successful solution.
Shared clarity is an essential part of the Agile project methodology. Cycles of small execution steps and regular clarification of queries (changes and approvals) affords a faster pace with better sync across all stakeholders. See Agile, Change-embracing, Accelerated Projects.
