A customer engagement progresses through understanding the problem, validating feasibility, defining scope, building a pilot, testing with users, rolling out, and transferring operational ownership. These steps can repeat as new facts emerge. They are a reasoning sequence, not a mandatory calendar.
Each stage produces evidence. Discovery creates a workflow map and assumptions. Scoping creates acceptance criteria and exclusions. Design creates architecture decisions. Implementation creates working software and tests. Acceptance records results and limitations. Handoff creates runbooks, training, and ownership.
A demo is useful for learning, but it does not establish that permissions, reliability, or adoption are solved. Keep assumptions visible and agree what must be true before expanding a pilot. Stop or revise when evidence contradicts the original idea.
Exercise: arrange the engagement artifacts in order and explain what decision each one supports. Add a loop for a pilot that reveals poor data quality.
Check: you can describe what must be learned before implementation and what must be demonstrated before handoff.
