Financial transparency
A first cost corridor and TCO perspective are available for investment decisions.
Assess
Assess establishes a decision-ready baseline for scope, readiness, economics, and risk before detailed migration design begins.
Understanding This Phase
Section titled “Understanding This Phase”Assess is the first phase of the STACKIT Migration Framework. It creates a fact-based baseline for migration decisions before architecture design and wave delivery begin.
The phase combines technical discovery with commercial and organizational alignment so that later migration work starts with clear priorities and transparent assumptions.
When Assess starts and ends
Section titled “When Assess starts and ends”Assess typically starts when a migration initiative has strategic sponsorship but no decision-ready baseline yet.
- Start when migration scope, business drivers, and decision stakeholders are defined at a high level.
- Build the baseline through Rapid Discovery, readiness evaluation, cost modeling, and stakeholder workshops.
- End when scope assumptions, migration readiness, and financial direction are clear enough to start detailed design.
Assess is completed when stakeholders can approve moving into Design and Mobilize with a shared understanding of cost, risk, and delivery feasibility.
Why this phase matters
Section titled “Why this phase matters”Assess reduces uncertainty early and aligns business and IT before large implementation effort is committed.
Readiness clarity
Gaps in technology, governance, capabilities, and operating model are visible early.
Stakeholder alignment
Leadership, delivery teams, and technical owners align on goals, scope, and expectations.
Risk reduction
Key assumptions and migration constraints are documented before target design starts.
Core modules in this phase
Section titled “Core modules in this phase”- Rapid Discovery: Establishes quantity baselines for early cost indication.
- TCO Report: Estimates total migration economics and long-term cost trajectory.
- Readiness Assessment: Evaluates migration readiness across technology and organization.
- Deep Dive Workshop: Builds technical understanding of STACKIT services and platform options.
- Briefings and Workshop: Aligns stakeholders and supports decision preparation.
Typical outcomes
Section titled “Typical outcomes”At the end of Assess, the program should have:
- Decision-ready baseline: A documented view of current landscape, scale, and migration scope.
- Initial economic model: Cost indication and TCO direction with transparent assumptions.
- Readiness and risk view: Prioritized gaps and mitigation needs for mobilization.
- Phase transition criteria: Clear entry conditions for Design and Mobilize.
Transition to Design and Mobilize
Section titled “Transition to Design and Mobilize”Assess does not finalize the full target architecture. Instead, it creates the validated input needed to start detailed design, migration-wave planning, and factory setup in the next phase.
