Scope
5 areas implies 29 topics across 6 modules
Started from the Replacing HR and payroll recipe — see the full worked plan. Add or drop anything below; it is a starting point, not an answer.
You did not pick these
Security & Identity, Financial Accounting, Integration, PMO & Programme Governance
Your streams cross into these modules, so the work happens there too. That is the part most scoping exercises miss.

Data in and out
What actually crosses the boundary, which way, how often, and what it costs when it stops.

Integration points
Every module boundary a stream crosses is an interface. The ones marked straddle your scope — you are changing one side and not the other, which is the interface most often missed at scoping and found during testing.

The order to do it in
Data Migration, Core HR
Nothing in scope blocks these — they can start together.
Benefits, Time & Attendance, Talent Acquisition, Learning & Development
Unblocked once the phase above is standing.
Payroll
Unblocked once the phase above is standing.
Cutover & Go-Live
Unblocked once the phase above is standing.
Sequence is a delivery judgement rather than a fact about the taxonomy. These are proposals from common tier-1 ordering — argue with them.
Assumed already in place
This scope depends on Programme Governance without including it. Fine if it is already standing and staying as it is — a gap in the plan otherwise.

This is a diagnosis, not a plan
Build takes the same scope and turns it into the documents somebody has to write — the investment brief, the business case, the plans — starting with what each one needs as an input before its headings can be answered honestly.
