eightpart

Eightpart is a term used in design and systems thinking to describe a framework for decomposing complex projects into eight interconnected domains. The eight parts are: goals and scope; stakeholders and governance; requirements and constraints; architecture and interfaces; data and workflows; quality assurance and risk; implementation and delivery; and evaluation and sustainment. The framework is intended to help teams balance planning, execution, and long-term viability.

The term appears in late-2010s professional discourse and in academic writing across software engineering, business design, and urban planning. It is not an official standard, but a heuristic intended to structure analysis, promote cross-disciplinary dialogue, and reduce omissions in project planning.

In practice, eightpart provides checklists, templates, and workshop formats that guide participants through each domain, prompting explicit consideration of goals, stakeholders, data needs, risk controls, and deployment plans. The eight-domain approach is designed to be adaptive rather than prescriptive, allowing teams to adjust the emphasis of each domain to fit context.

Eightpart variants exist, with practitioners adapting the framework by merging or splitting domains or substituting domain names to reflect discipline-specific concerns. Critics argue that the framework can become a mechanical exercise if used without a clear purpose, and that rigid eight-part divisions may overlook interdependencies that span multiple domains.
