How It Fits Together: Methodology Foundation & Core Principles
Deterministic NUP connects its four core concepts into a cohesive, repeatable operating system for regulated engineering. By separating "what to do" (Disciplines and Activities) from "when to do it" (Phases) and "what evidence is produced" (Artifacts), the methodology enables teams to practice agile, incremental development without ever sacrificing regulatory rigor or role accountability.
Separation of "What", "When", and "Evidence"
The power of the Netspective Unified Process lies in its method architecture. Traditional methodologies often blend process steps, job titles, and documents into rigid waterfall stages that break down during agile iterations. NUP solves this by establishing clean boundaries between four core concepts:
Lifecycle Phases
Provide the temporal structure and milestone gates for the project.
Disciplines
Provide the specialized skills and knowledge domains.
Activities
Define the specific, repeatable units of work executed by roles.
Artifacts
Capture the tangible, version-controlled deliverables and audit proof.

Key Methodology Principles
1. Iterative and Incremental Delivery
Regulated software is not built in a single massive phase. Early iterations eliminate architectural risk (Elaboration), while later iterations build production features (Construction) with continuous automated compliance checks.
2. Role-Based Responsibility & Independence
Every activity assigns explicit responsibility to defined roles. To satisfy FDA and ISO standards, verification and review roles maintain independence from authoring roles.
3. Artifact-Centric Audit Tracking
Compliance is proven through version-controlled artifacts, not spoken claims. Traceability matrices dynamically link user needs to code commits, test logs, and risk mitigations.
4. Evidence or Silence (Tier-2 Grounding)
All regulatory claims in NUP are anchored to explicit clauses from ISO 13485, ISO 27001, FDA 21 CFR §820, or IEC 62304, ensuring engineers and auditors share verifiable common ground.
