== Basic considerations ==
In civil-engineering practice, the purpose of ''project definition'' is to transform a sponsor’s need or intent into a defensible and communicable basis for decisions. Those decisions include:
* whether to proceed (or stop),
* what outcomes are required,
* what constraints govern the work,
* what level of funding and authority is being committed, and
* what the project team is accountable for delivering.

Project definition is therefore a decision-support activity. It does not require full knowledge; it requires ''sufficient clarity'' to authorize the next phase of work while explicitly documenting what remains uncertain.

== Semantic, Epistemic and Logical frameworks ==
''(Under construction)''

=== Semantic framework ===
Common semantic problems include:
* confusing ''project definition'' with ''project development'' and ''project execution'',
* using ''requirements'', ''scope'', and ''specification'' as interchangeable terms,
* treating “baseline” as if it were purely cost/schedule, rather than a structured commitment across scope, performance, and constraints.

Working distinctions used in RiskWiki:
* '''Project definition''' answers: ''What are we trying to achieve, for whom, under what constraints, and why is it justified?''
* '''Project development''' answers: ''How will we engineer and package a feasible solution, and what artifacts will govern delivery?''
* '''Project execution''' answers: ''How do we implement, control, integrate, verify, and deliver acceptance?''

Requirements vs specifications (working distinction):
* '''Requirements''' state ''what must be achieved'' (performance, function, constraints, acceptance).
* '''Specifications''' state ''how compliance will be demonstrated or implemented'' (materials, methods, standards, testing, tolerances, submittals).

=== Epistemic framework ===
Project definition operates under high uncertainty (often dominated by epistemic uncertainty). The objective is not to eliminate uncertainty, but to:
* identify the most decision-relevant uncertainties,
* document assumptions and their rationale,
* establish learning/validation steps (“risk burn-down” actions),
* decide which uncertainties must be retired before authorization to proceed.

Project definition should explicitly document:
* key unknowns,
* the plan for reducing unknowns,
* who owns which uncertainties (stakeholders / contracts),
* which uncertainties are being accepted (and why).

=== Logical framework ===
The logical structure of project definition is centered on decision gates (“off-ramps”):
* definition produces artifacts,
* artifacts support governance reviews,
* reviews authorize (or terminate) transition into development.

A definition is “good enough” when it supports:
* a coherent statement of purpose and outcomes,
* traceable requirements,
* a plausible concept of solution,
* a defensible cost/schedule range (not a false point estimate),
* an explicit initial risk posture and allocation.

== Practice frameworks for Project Definition ==
(Under construction.)

Typical civil-engineering practice elements include:
* business case / sponsor justification
* alternatives analysis (including “do-nothing”)
* concept of operations / operational needs
* requirements definition (functional + performance)
* constraints definition (regulatory, right-of-way, stakeholder, constructability)
* initial delivery strategy (how the project will be delivered and by whom)

== Core artifacts and decision outputs ==
A working “minimum set” of definition artifacts (varies by program and agency):
* Sponsor intent / mission need statement
* Stakeholder map and decision rights (who decides what)
* Functional and performance requirements
* Initial scope boundaries (what is in / out)
* Conceptual design / concept sketches or models (solution hypothesis)
* Assumptions register (including critical assumptions)
* Constraints register (regulatory, physical, environmental, institutional)
* Initial cost range and schedule range (with basis and uncertainty)
* Initial risk register (risk statements tied to requirements and constraints)
* Initial procurement / delivery-method recommendation

== Interfaces to uncertainty and risk management ==
Project definition is where “risk to whom?” becomes operational.
Key outputs should make explicit:
* which requirements are fixed vs negotiable,
* who defines acceptability (authority having jurisdiction, owner, users),
* what “feasible” means at this stage (technical + regulatory + deliverability),
* which uncertainties are being carried forward into development,
* which uncertainties must be retired before procurement and construction.

== Working definition of the term ==
Project definition
:Project definition is the disciplined process of establishing and documenting the project’s purpose, required outcomes, requirements, constraints, and initial solution concept at a level sufficient to support governance decisions, authorization of funding, and transition into project development.

== Limitations of the definition ==
(Under construction.)
* The degree of definition required varies by delivery method and by regulatory environment.
* Some programs label “definition” as programming, feasibility, initiation, or conceptual planning.
* A definition can be overconfident: false precision can be more harmful than explicitly stated uncertainty.

== Beneficial Outcomes ==
(Under construction.)
A well-structured project definition improves:
* alignment among stakeholders,
* quality of downstream design decisions,
* defensibility of cost/schedule commitments,
* risk identification and allocation,
* the ability to terminate weak projects early.

== Learning Outcomes ==
(Under construction.)
After mastering this article, the reader should be able to:
* distinguish requirements from specifications,
* describe what artifacts enable definition-stage decisions,
* explain how project definition sets the initial risk posture.
