Application Portfolio & Platform Architecture
A structured review of the applications, platforms and dependencies an organisation has accumulated over time — mapping overlap, ownership gaps and integration boundaries to define a clearer target structure.
Indicative starting price. Final pricing depends on scope and is confirmed in a written proposal.
When this service is usually considered
- Several systems appear to duplicate the same function, but ownership is unclear.
- New applications have been added over time without a coordinated plan.

- A merger, acquisition or restructure has combined previously separate application estates.
What the review covers
- Application inventory.
- Dependency review between systems.
- Duplicated capability identification.
- Ownership gaps across the estate.
- Integration boundaries and data flow.
- Platform rationalisation options.

What sits outside the starting scope
Guaranteed technical outcome
Recommendations are evidence-based but do not guarantee a specific technical or commercial result.
Implementation of changes
This service delivers the review and target architecture; implementing the changes is a separate, individually scoped project.
Vendor negotiation
Commercial negotiation with existing software vendors is not part of this service.
Ongoing architecture governance
Ongoing architectural oversight is a separate, optional arrangement.
Application Portfolio & Platform Architecture — FAQ
No. Where documentation is incomplete, the review draws on structured conversations with your team instead, though this may extend the timeline.
The review identifies duplicated capability and overlap, but does not guarantee a specific cost outcome from any resulting consolidation.

There is no fixed limit; scope and duration are agreed based on the size of the estate during the proposal stage.
Yes, combined estates following a merger or acquisition are a common reason organisations commission this review.
