Deliverables & success metrics

What you get — and how we measure it.

Deliverables

  • Production-Ready Code: Code that’s fully tested, optimized, and ready for deployment.
  • API Specs (OpenAPI): Detailed documentation of API endpoints, methods, and data structures.
  • Runbooks: Step-by-step guides for maintaining and troubleshooting the system.
  • Handover Docs: Documentation to facilitate knowledge transfer to operations or support teams.

Success metrics

  • Lead Time for Change: Time taken from code commit to deployment in production.
  • Change Failure Rate: Percentage of changes that result in failures or incidents.
  • Unit/Integration Test Coverage: The proportion of code covered by automated tests.
  • MTTR (Mean Time to Recovery): Average time taken to restore service after a failure.
We don’t just develop software — we own and operate the infrastructure it runs on. That gives our clients control, security and performance most vendors simply can’t offer.
