Connecting information should not obscure who is allowed to use it.
A combined view can create new exposure when permissions, ownership and data-handling rules are not carried into the design. Those boundaries need review before access expands.
Define useful operational context together with the restrictions that apply to it, so the integration scope is grounded in both the decision and its responsibilities.
Inventory the required fields, purposes and authorized roles. Design the working view around those boundaries; request implementation evidence and negative-access tests before treating a control as established.
Core design considerations
Data inventory
establish owners, sensitivity and intended use.
Access design
specify allowed views and disallowed combinations.
Evidence review
verify behavior with documented tests and controls.
A workflow worth proving
Who can see, decide and act?
Define authorization, audit, retention and deletion requirements for the intended workflow. Test permitted and denied access before expanding its scope.
Fit the implementation to the environment.
Review where data is read, copied, transformed and retained. Confirm available interfaces and controls for every boundary.
Agree what success would mean.
Demonstrate both useful authorized access and correct denial. Record unresolved controls as launch blockers, with named owners.
