This domain has one supplier layer, not two: strategy and governance work is advisory, so there is no product to license and every company here is a delivery firm. They divide by where their leverage sits — management consultancies that argue the business case to a board, and engineering-led firms that write a roadmap they could execute themselves. Evaluate them on whether the deliverable is a portfolio decision you can act on or a document: ask for the assessment method, the rationalization criteria, and who owns the resulting sequencing. Because no company here commits to an implementation approach, this page carries no approach axis; the migration paths and services in this hub's siblings are where those commitments are documented. Companies appear alphabetically, and every one of them is enterprise-scale — this is not a market with a boutique tier.
