Which SDLC Phases Do Not Require a Dedicated IT Operating Environment?

This chapter identifies phases that commonly do not require dedicated runtime Environments and explains why governance still applies.

Common Non-Environment Phases

Intake & Strategizing, Planning, Requirements Capture, Release Post-Mortem and Closing, and portions of Retirement planning commonly require no dedicated runtime Environment. Research and Design may use tools, sandboxes, or prototypes when useful but do not always require a dedicated Environment.

Governance Without a Runtime Context

A phase without a dedicated Environment still requires ownership, Activities, Artifacts, documentation, evidence, authoritative records, decisions, and exit criteria. Collaboration tools and repositories support the work but should not be confused with runtime Environment Types.

Avoid Artificial Environment Requirements

Creating a dedicated Environment for every phase adds cost and complexity without necessarily improving outcomes. Environment selection should follow the claim, Activity, risk, and evidence need.

Common Antipatterns

Enterprises should avoid creating a dedicated Environment for every phase, including ones that don’t need one. Intake, Planning, and Requirements Capture commonly require no dedicated runtime Environment at all; creating one anyway adds cost and complexity without improving outcomes, and can obscure the difference between genuine Environment needs and collaboration tools that merely support the work.
