Software maintenance & modernisation

Software maintenance and application modernisation for systems that still have work to do. Wyxos reviews existing applications, identifies the changes that matter, and improves them in manageable stages.

Where work gets stuck

An application may be slow, difficult to change, or dependent on outdated components. The original developer may be unavailable, and a full replacement may introduce more cost and disruption than the problem requires.

A system for the next step

We inspect the code, runtime, data, and existing tests, then agree a prioritised plan. Work can include reproducing and fixing bugs, adding features, improving slow operations, upgrading dependencies, or replacing individual components.

A clear deliverable

  • A review of the application and the access needed to maintain it.
  • An agreed list of fixes or improvements with clear acceptance criteria.
  • Checks for affected workflows and a deployment and recovery plan.
  • Updated documentation and handover notes for the changed parts.

Focused improvements to the software you already use, with known risks and a clear way to verify each change.

Maintaining business applications

Existing business applications need changes as requirements and dependencies evolve.

Our agency work includes principal maintenance responsibility on established applications, alongside collaborative development on others.

The work connects knowledge of the existing application with continued feature development and maintenance.

Is this the right approach?

Maintenance is a useful starting point when the application still supports the business. A larger rebuild may be warranted if its foundations prevent the required changes. The review establishes that before committing to either approach; ongoing support arrangements are agreed separately.

What to include in your request

  • What application do you use, and which parts need attention?
  • Do you have access to its source code, hosting, and documentation?
  • What happens now, and what should happen instead?
  • Which workflows must remain available during changes?
