Recovering Technical Ownership of a Poorly Documented Legacy System
A critical custom .NET platform had become difficult to support because its technical knowledge was no longer available internally. The engagement focused on learning the system, stabilising important workflows and creating shared support knowledge.

The operating constraints
What the project needed to address
- Important operating behaviour was not captured in maintainable documentation.
- Legacy code and integrations made the consequences of changes difficult to predict.
- Incident response had to continue while the team learned and documented the system.
Support scope
Reconstruct system knowledge and stabilise critical behaviour
The team combined source review, runtime evidence and discussions with operational stakeholders to reconstruct system behaviour. Targeted fixes and support documentation helped establish technical ownership.
Support activities
Learn, document and improve the operating environment
Collected available code, logs, data-flow information and user knowledge.
Mapped dependencies and important workflows, prioritising areas with business impact.
Addressed high-risk faults and added documentation or diagnostics to support future investigation.
Maintained support runbooks, release practices and a continuing improvement backlog.
