Modernisation
Application modernisation services
The application everyone complains about is usually also the one that encodes how the business actually works. Replacing it wholesale throws away both.
The problem
Rewrites fail because the old system knows things nobody wrote down
Years of exceptions, approvals and edge cases live inside the application rather than in any document. A clean-sheet rewrite rediscovers them one production incident at a time, which is why so many modernisation projects end up costing more than the system they replaced.
How we work on this
Prototype first, then the build you approved.
We prototype the replacement of one workflow first and put it in front of the people who use the current system daily. Their reaction surfaces the undocumented rules early. We then modernise in slices, keeping the parts people rely on recognisable, with the data migration and the cutover agreed before anything moves.
What this covers
Capabilities, and where each one stops.
-
Workflow-by-workflow replacement
Modernising in slices that each deliver something usable, instead of a single switchover with one chance to be right.
-
Data migration
Moving history with its exceptions intact, and saying plainly what cannot be moved cleanly.
-
Interface modernisation
A usable, mobile-capable interface over processes your people already know.
-
Integration with what stays
Keeping the systems you are not replacing connected throughout.
-
Decommissioning plan
What gets switched off, when, and what is archived first.
We do not recommend a rewrite where a fix would do. If the honest answer is that your current system needs three changes rather than a replacement, that is what the assessment will say.
How it is built
Decisions we make the same way every time.
- Read-only access to the existing system for assessment
- Slice-by-slice cutover with a rollback path at each step
- Parallel running where the risk warrants it
- Business rules documented as they are found
- Open export of migrated data at any time
Where this applies
Industries we have gone deep in, and the rest of the ecosystem.
Questions
The questions people ask about this work.
Do we have to replace everything at once?
No, and we would advise against it. We modernise one workflow at a time, each slice usable on its own, with a rollback path.
What happens to our historical data?
It is migrated with its exceptions intact where that is possible, and we tell you plainly where it is not. Your data stays exportable in open formats throughout.
All questions, including the ones that might lose us the deal
Describe the system you are stuck with
Tell us what it does well and what it makes people do by hand. We will prototype one replacement workflow.
