Glossary — Key Terms

A shared vocabulary is a prerequisite for CMM Level 3. All staff should be able to define and apply these terms without reference.

Term	Definition
TOGAF	The Open Group Architecture Framework. The world’s most widely adopted Enterprise Architecture framework, providing the ADM guidance, reference models, and governance structures.
DBJ Method	A right-sized adaptation of TOGAF designed for smaller, fast-moving organisations. Preserves TOGAF’s maturity model and domain structure while reducing ceremonial overhead.
Enterprise Architecture (EA)	The practice of aligning an organisation’s strategy, processes, information, and technology into a coherent, governed whole. EA makes complex decisions tractable and auditable.
CMM	Capability Maturity Model. A five-level framework (Initial → Repeatable → Defined → Managed → Optimising) that measures the maturity of an organisation’s processes and practices.
CMM Level 3 (Defined)	The state where processes are fully documented, standardised, and integrated across the organisation. All domains operate from a shared playbook. Boot Camp target.
Domain	One of three organisational operating areas in the DBJ Method: Business, Products, or Technology. Each domain has a distinct mandate, accountabilities, and artefact responsibilities.
Business Domain	Sets strategic intent, commissions initiatives, defines outcome criteria, and conducts User Acceptance Testing (UAT). Owns the decisions on why and the what.
Products Domain	Translates Business strategy into Technology-ready requirements. Manages the backlog, owns the solutions, and coordinates UAT. The bridge domain in the (BPT) B→P→T→P cycle.
Technology Domain	Builds, integrates, and operates systems per the product specifications. Applies technical governance and architecture standards. Owns the how it’s built decisions.
(BPT) B→P→T→P Cycle	The DBJ Method’s core operating rhythm. Business commissions → Products translates → Technology builds → Products stages for UAT → Business accepts. Iterative and domain-explicit.
UAT	User Acceptance Testing. The formal process by which the Business domain validates that a delivered increment meets the outcome criteria set at commission. Outcome is passed onto “final” P –> T for deployment and the cycle closure.
Bridge to AI	The DBJ thesis that CMM maturity is the prerequisite for responsible AI adoption. AI is layered into processes progressively at L3 (documentation), L4 (decision support), and L5 (optimisation).
(DBJ) ADM	Architecture Development Method. Simplified TOGAF phase model (Preliminary → A through H → Requirements Management) for developing and evolving enterprise architecture.
Domain Lead	The designated accountable person for architecture decisions within a domain. Co-owns cycle governance alongside other Domain Leads. Escalates cross-domain conflicts to shared resolution.
