Systems Engineering Requirements Kit

ISO 15288 and 29148 requirements: ConOps and OpsCon, stakeholder and system requirements, SRS, EARS style, review, V&V and tracing.

10 templates in 3 steps, in the order you use them. Open any template in the editor, fill it in and export it to PDF, DOCX or HTML.

Step 1

Framing

  1. Concept of Operations (ConOps) Template

    Full

    ConOps and OpsCon per ISO/IEC/IEEE 29148: current situation, justification for change, proposed operations, scenarios, impacts, alternatives, 15288 process map

    ISO/IEC/IEEE 29148:2018 (ConOps, OpsCon); ISO/IEC/IEEE 15288:2023; IEEE 1362-1998 superseded

  2. System Operational Concept (OpsCon) Template

    Full

    System-level OpsCon: boundary, environment, user classes, modes and states, operational scenarios, support concept, constraints, impacts, trace to StRS

    ISO/IEC/IEEE 29148:2018 (OpsCon information item)
Step 2

Requirements

  1. Stakeholder Requirements Specification (StRS) Template

    Full

    Stakeholder needs per group with attributes, business context, operational modes, scenarios and traceability (StRS)

    ISO/IEC/IEEE 29148:2018 (Edition 3 at DIS)

  2. System Requirements Specification (SyRS) Template

    Full

    System-level requirements: functions, performance, interfaces, modes, environment, security, sustainment, with parallel verification

    ISO/IEC/IEEE 29148:2018, ISO/IEC/IEEE 15288:2023

  3. Software Requirements Specification Template (ISO/IEC/IEEE 29148)

    Full

    Full SRS per ISO/IEC/IEEE 29148:2018 for contract or multi-team work: interfaces, functions, quality attributes, verification matrix, traceability

    ISO/IEC/IEEE 29148:2018 (Edition 3 at DIS)

  4. Non-Functional Requirements & Quality Attribute Scenarios Template

    Full

    ISO/IEC 25010:2023 qualities, utility tree priorities, six-part scenarios, measurement methods and acceptance thresholds

    ISO/IEC 25010:2023, SEI quality attribute scenarios

  5. EARS Requirements Style Guide Template

    Lean

    EARS sentence patterns: generic clause order, ubiquitous, state-driven, event-driven, optional feature, unwanted behaviour, complex, project rules, rewrites

    Mavin et al., EARS (RE 2009)
Step 3

Verification

  1. Requirements Review Checklist Template

    Standard

    Requirements inspection: review details, per-requirement checks by 29148 characteristic, set checks, defect log, defect density summary, sign-off

    ISO/IEC/IEEE 29148:2018 5.2.5 and 5.2.6 (names only); INCOSE GtWR v4

  2. Verification and Validation Plan Template (IEEE 1012)

    Full

    V&V plan: integrity level scheme, tasks per life-cycle phase, minimum tasks by level, independence, anomalies, reporting, schedule

    IEEE 1012-2024

  3. Requirements Traceability Matrix (RTM) Template

    Standard

    Forward and backward links from business need to tests and results, coverage metrics, orphan analysis, change impact

    ISO/IEC/IEEE 29148:2018 (Edition 3 at DIS stage)
