Enterprise Technology

Change critical software without losing its business knowledge.

Modernize applications through bounded releases, explicit interfaces, and acceptance criteria tied to the work they support.

The challenge

The old system still has to run.

A legacy application often contains years of undocumented business rules. Replacing its technology before understanding those rules adds delivery risk.

Implementation considerations

Make the boundaries explicit.

Recover the domain model

Review user journeys, integrations, operational incidents, and critical business rules. Characterize existing behavior so teams can distinguish intentional change from regression.

Create manageable boundaries

Separate responsibilities behind clear interfaces and migrate incrementally where practical. A modular application can be the right choice; distributed services need a concrete operational justification.

Release with a recovery path

Use representative test data, migration checks, staged rollout, and rollback procedures. Define ownership for both the transition period and the final operating model.

Technical perspective

The architecture behind the work.

New boundaries are what make a staged release reversible.

Scope the first step

Before the first commitment.

Is a rewrite safer than incremental change?

Rarely. Recovering the domain model from the existing system, then releasing through staged boundaries with a recovery path, keeps the service running while its shape changes underneath.
