SAP program leaders building an early business case before a complete landscape assessment.
Which evidence has the largest effect on estimated effort and where an initial range is too uncertain to support a budget commitment.
Decision context
A migration calculator cannot produce a reliable implementation quote from employee count or revenue alone. Custom objects, interfaces, source quality, system count, process variation, test coverage, program mode, validation boundaries, and cutover constraints drive work in different ways.
This calculator produces a relative effort range and highlights uncertainty. It does not use hidden customer benchmarks, vendor rate cards, or a claim that two landscapes with the same object count require the same delivery plan.
Use the output to identify which inventory to collect next. A supported Adranum workspace can replace assumptions with source coverage, dependencies, findings, data-quality evidence, process observations, and impacted tests.
Interactive estimator
Estimate relative migration effort
Values stay in this browser. The score is a planning signal, not a quote or timeline.
What the workflow must cover
Complexity inputs
Model systems, custom objects, interfaces, data volume, process variants, test coverage, deployment mode, and program type separately.
Range, not false precision
Return a relative effort band and uncertainty drivers instead of a currency promise unsupported by a landscape assessment.
Evidence checklist
Translate high-impact assumptions into the exports, contracts, and observations needed for a defensible assessment.
Private by default
The browser calculation is local to the page and does not upload entered planning values.
Implementation workflow
Start with a bounded customer scenario and explicit acceptance criteria. Preserve native SAP permissions and accountable review while the software creates a repeatable evidence chain.
- Enter approximate landscape counts.
- Choose the migration program and deployment constraints.
- Review the relative range and uncertainty drivers.
- Collect the recommended evidence.
- Run a supported workspace assessment before committing budget or timeline.
Evidence to require
A transformation claim should resolve to observable artifacts, decisions, and execution receipts. Ask for the following evidence in a representative evaluation:
- Input assumptions
- Complexity weighting
- Uncertainty drivers
- Recommended evidence
- No uploaded customer data
Boundaries and non-claims
Adranum separates analysis, proposal, human review, package creation, customer-local validation, and production execution. A later state never rewrites the evidence that supported an earlier decision.
- The result is not a quote, forecast, or delivery commitment.
- Rates, team capability, geography, vendor contracts, licensing, and organization readiness are not modeled.
- A representative technical assessment is required for planning.
Buyer checklist
- Which inputs are measured versus guessed?
- How many interfaces are truly in scope?
- What percentage of custom objects is active?
- Which critical process paths lack tests?
- What data and model boundaries will procurement require?
