Technology Portfolio Management (TPM) Best Practices

Overview

The Technology Standards Register and the Enterprise Technology Radar serve complementary governance functions and address complementary organizational needs. Treating them as alternatives — maintaining one but not the other — leaves a significant gap in either the governance record or the governance communication. The Standards Register without the Radar is authoritative but inaccessible to much of its intended audience. The Radar without the Standards Register is visible and engaging but lacks the governance precision and auditability that formal technology decisions require.

Best Practice

Use the Technology Standards Register and Enterprise Technology Radar as complementary governance tools with a defined relationship between them. The Standards Register is the system of record: it carries the complete, structured governance data for every technology position the organization has taken, with full provenance, rationale, conditions, and update history. The Radar is the communication and deliberation interface: it presents a curated, visually accessible view of the most relevant technology positions for the organization’s current engineering community, organized to promote discovery and discussion. The Radar should be derived from the Standards Register rather than maintained independently of it. Every position change on the Radar should correspond to a Standards Register entry update. The Radar’s Adopt ring corresponds to the Standards Register’s Approved status. The Radar’s Hold ring corresponds to the Standards Register’s Deprecated status. The Radar’s Assess and Trial rings correspond to the Standards Register’s Under Evaluation status at different stages of the evaluation process.

Benefit(s)

Using the Standards Register and Radar together produces governance communication that is simultaneously authoritative and accessible. The engineering community engages with technology positions through the Radar format that works for their communication preferences. Governance and compliance requirements are met through the Standards Register that provides the structured, auditable record that formal governance requires. Neither tool must compromise its purpose to serve the other’s audience because they are designed to complement each other’s strengths.
