Existing-estate investigation
Legacy & Portfolio Understanding
See the dependencies before planning the change.
Investigate a defined legacy or application portfolio to understand coupling, technical constraints and candidates for deeper assessment.
What you receive
The result of this engagement.
A scoped estate and dependency view identifying technical constraints, modernization candidates and investigation priorities.
- An agreed-scope application/dependency map.
- A technical constraint and investigation-priority scorecard.
- A decision brief identifying modernization candidates and evidence gaps.
When this helps
Recognize the situation.
- System knowledge is fragmented across teams and old documentation.
- Modernization priorities depend on hidden integration or data dependencies.
- You need a technical inventory and a defensible basis for the next investigation.
How the work unfolds
Evidence appropriate to the question.
Define the estate boundary
Agree systems, source access, business context and the decision the scan should inform.
Map the technical landscape
Use relevant code, documentation and owner context to investigate dependencies, coupling and technical debt indicators.
Identify the next questions
Validate material observations and distinguish candidates for action from areas needing deeper evidence.
Scope & responsibility
Agree the depth. Keep the boundaries clear.
Scope of the engagement
Depth varies with estate size, languages, source condition and owner participation. A portfolio scan is not a fixed promise to reconstruct an entire enterprise in a few days.
Appropriate reliance
This is a scoped technical investigation, not a complete financial portfolio valuation, legal classification or full architecture assessment of every application.
The agreed engagement sets the coverage, deliverables, responsibilities, timing and fees. Changes to that scope are agreed explicitly.
Practical questions
Before engaging us.
Is this only about introducing AI?
No. Understanding an estate is valuable for handover, consolidation and modernization whether or not AI is part of the response.
