Technical Reference Model

A Technical Reference Model (TRM) taxonomizes platform services—compute, storage, middleware, security—and maps approved products and versions to each category. It supports rationalization, obsolescence planning, and standards enforcement. TRMs often align to industry or federal reference models while reflecting local approvals.

In Practice

Larkinized LLC maintains TRMs as living catalogs integrated with procurement and architecture review checklists. Heatmaps plot applications against TRM categories to expose unsupported technologies. TRM updates trigger impact analysis for dependent systems.

Example

A TRM heatmap shows fifteen applications on a database version slated for end-of-support within twelve months.
