Reviewable material for handover
A handover is easier to review when the receiving team can examine the requirements, discovery records, models, and metadata together. Those artifacts explain the intended behavior and preserve the connections between a business decision and its implementation.
Reviewable material gives a team a basis for understanding the work without relying only on an implementation or an undocumented explanation from its author. Requirements describe the business decision, while models and metadata show how that decision is represented in the delivery.
