Senior RPG and COBOL expertise is retiring. Maintenance backlogs on IBM i are growing. And the generic AI coding tools that work well for greenfield development tend to flounder in legacy Power environments. IBM Bob is built differently. It is trained on IBM i, with native awareness of RPG, CL, DDS and embedded SQL, and it operates as a system-level AI partner with the context, governance and auditability enterprise modernisation needs. This short guide explains what Bob does, where the productivity gains come from, and how Northdoor helps you deploy it safely on your Power estate.

What you will get from this guide

  • The case for modernising IBM Power now, and the cost of waiting
  • Why generic AI coding assistants struggle in legacy IBM i environments
  • How Bob delivers deep context awareness, end-to-end task orchestration, governance gating and AI-generated documentation
  • The productivity numbers IBM is reporting from its own development teams using Bob, including 20 to 80 per cent gains in software development and 20 to 40 per cent acceleration on complex engineering work
  • Six Northdoor service lines built around Bob, from legacy code analysis through to DevOps enablement
  • Hands-on feedback from Northdoor engineers who have tested Bob

Who it is for

CIOs, CTOs, heads of application development, IBM i platform owners and modernisation leads at organisations running business-critical workloads on IBM Power.
