1 Interfacing Risk and Systems Engineering – Left Shift Risk Management Incose Conference 9 th November 2007 Val Jonas

2 Agenda Basics of Systems Engineering The concept of Left Shift Application to three stages of Systems Engineering Conclusions

3 Systems Engineering Systems Engineering consists of the technical and management processes used to transform operational needs, concepts, and policies into a system configuration that optimises the total system design to meet cost, schedule and technical performance objectives.

4 Requirements process Operational use User requirements System specification Subsystem specifications User tests System tests Subsystem tests Acceptance tests Capability requirements Statement of need Customer Supplier Customer Supplier

5 Operational use User requirements System specification Subsystem specifications User tests System tests Subsystem tests Acceptance tests Capability requirements Statement of need Traceability and Compliance satisfies validating the User verifying the system qualifying the subsystems qualifying components

6 No. of Problem causes Established Cost of Recovery Tackled as potential problems Emergence as problems

7 Left shift during 3 stages Understand context Create the baseline requirements acceptance criteria Manage change

8 Operational use User requirements System specification Subsystem specification User tests System tests Subsystem tests Acceptance tests Capability requirements Statement of need Stage 1 - Understand context Economic, environment, market influences Options considerations Business benefits Portfolio Analysis

9 Case study: Rail industry Requirement: increased passenger capacity 1. More seats (added safety requirements) 2. Longer trains (longer platforms) 3. Double-decker trains (taller tunnels) 4. High speed trains (upgraded track) Options comparison Schedule, budget, resources Procurement strategy Lease value and life Reputation / image GDP Investment / financing environment Evolving stakeholder expectations Competitors Change of London Mayor Options analysis Benefits case Economic, environment, market influences Overlap with Technical Upgrade Programme Portfolio analysis

10 Stage 2 – Create the baseline Operational use User requirements System specification Subsystem specification User tests System tests Subsystem tests Acceptance tests Capability requirements Statement of need Identify risks against requirements & develop mitigation strategies Risk and Action Register Supplier 1 Risk Register Identify sub-system requirements risk (in lower level risk registers) Supplier 2 Risk Register Requirements & Acceptance Criteria Identify risks to achieving compliance

11 Case study: Utilities Requirement: National infrastructure upgrade Difficulty gaining stakeholder agreement Long-winded ministerial approval process Need for public consultations Change of government / general election New health & safety legislation Related disaster Influence of regulatory review New leases non-compliant High level risks to achieving requirements Acceptance risks New technology unavailable Failure to achieve wayleave consent Raw materials not availabie Legacy platform restricts design options Low level risks to achieving requirements System platform incompatibility Obsolete technology Failure to reach reliability targets Insufficient trials Sub-system Acceptance risks

12 Stage 3 – Manage Change Case study: UK MoD Manage scope creep Write requirements in sufficient detail Enforce rigorous change and configuration control Evaluate potential change in advance Traceability (Doors) Risk assessment (Predict! and ARM) & risk analysis (Predict!) Beware of opportunities – they can bite!

13 No. of Problem causes Established Cost of Recovery Tackled as potential problems Emergence as problems
