Manufacturing is not a type of IT work in DevOps.
DevOps classifies IT work as:
Business projects: New value-creating work.
Planned work: Routine, repeatable tasks (maintenance, upgrades).
Unplanned work: Incidents, emergencies, support.
Extract-style reference:
“IT work includes business projects, planned work, and unplanned work. Manufacturing is an
analogy for flow, but not a category of IT work itself.”
— The Phoenix Project
PeopleCert DevOps Foundation v3.6: Recognizes these three categories to manage and improve IT
workloads.
