About
Mainframe DevOps, done by the people who do the work
Strongback Consulting moves z/OS shops off legacy source control and into modern delivery — Git, impact-aware builds, automated deployment — and we do the work ourselves, with engineers who have done these migrations before.
Mainframe DevOps since before it had a name
Long before “DevOps” reached the mainframe, we were bringing modern delivery discipline to z/OS — version control, automated builds, and governed deployment — for organizations whose most critical systems run on COBOL, PL/I, and Assembler. That’s still the whole business: not a side practice bolted onto a distributed consultancy, but the thing we do.
The through-line has always been the delivery model. The people on your engagement are senior mainframe engineers who have opened an Endevor panel, written a Dependency Based Build, and debugged a statically bound load module — because they have done this migration before. You are not funding someone’s on-the-job z/OS education.
A consultancy, not a body shop
We do the work directly
The migration and the DBB implementation are done by us — no prime-contractor markup, no subcontracted z/OS work, no multi-year transformation program you can’t get out of.
Real mainframe engineers
Every engagement is staffed with people who have migrated production systems off Endevor, Librarian, and Panvalet — not generalists learning the platform on your project.
Modern practice, mainframe discipline
We bring Git, CI/CD, and automated deployment to z/OS without flattening the promotion path, the audit trail, or the batch window your business depends on.
It starts with an assessment, not a statement of work
We begin by mapping what you actually have — the dataset structure, the promotion path, the build and deployment reality — and telling you what moves first and what can wait. Then we do it in stages you can pause at, with your live systems never at risk. Where a tool is the right fit we say so; where it isn’t, we say that too. We would rather scope a smaller engagement that succeeds than sell a larger one that stalls.
Beyond migration, we train the teams who inherit these systems — a hands-on IDz curriculum for mainframe developers, and, through the Island Training Solutions curriculum now part of Strongback, instructor-led IBM Engineering Lifecycle Management (ELM) training.
We’re not a systems integrator selling a multi-year transformation program. We do the migration and the DBB implementation directly — with mainframe engineers who’ve done this before.

A migration assessment maps your environment against a modern z/OS delivery model — no commitment, no generic sales deck.
