SSEI Vision
  • The SSEI is an MOD-funded strategic initiative
    intended to enhance through-life capability
    management for software intensive defence
    systems, and thus to reduce risks, delays and
    cost overruns.

Lt Gen Andrew Figgures DCDS(EC)

Software Engineering is Different
  • Software is pure design
  • No manufacture, no raw material, no cost to
    replicate deliver
  • Potential for rapid, safe upgrade not yet
    realised
  • Software problems are not easily absorbed because
    of
  • Complexity unintended side effects
  • Integration extensive side effects
  • Software science, technologies methods and tools
    arenot stable or mature e.g. aerospace
  • 70s, 80s Functional design assembler
    custom h/w
  • 80s, 90s Object Oriented HOL COTS h/w
  • 90s, 00s Model Driven COTS o/s, h/w

7
Why Software Engineering is Special
  • Software is inscrutable
  • Potential to be disruptive beyond its cash value
  • Range of development standards
  • Enables increase in system complexity

8
Perception of Defence Software Systems
  • Failure to meet specification
  • Expensive
  • Always late

9
Formation of the SSEI
  • BAE Systems (Military Air Solutions) was selected
    by MOD to hold the contract on behalf of an
    industry and academia consortium
  • Consortium formed from an amalgamation of all
    bidders
  • IBM, MBDA, AeI, QinetiQ, YorkMetrics, SEIC, EDS,
    Insyte
  • Universities of York, Newcastle, Loughborough,
    Oxford
  • Mixture of basic and applied research tasks plus
    an enabling contract for additional services

10
SSEI Management and Governance

  • Diversity of funding
  • MOD
  • Wider Government
  • Industry
  • Recognised body for SSE accreditation
  • Individuals
  • Organisations
  • Expanding range of services offered

14
Contents
  • Establishment of the SSEI
  • Current SSEI Programme
  • SSEI Future Developments
  • Conclusions

15
SSEI Research Programme
  • Programme has five themes
  • Management, especially evidence based
  • Architecture, including SoS
  • Integration
  • Dependability, e.g. safety and security
  • Properties
  • Initial three year programme funded, with 13
    tasks
  • Engagement possible via Special Interest Groups
    (SIGs)

16
Current Research Tasks
  1. IMS for Adaptive Systems (SEIC)
  2. Evidence Based Management (York)
  3. Evidence-Based Infrastructure (YorkMetrics)
  4. Framework for Distributed Development and
    Integration (SEIC)
  5. Model-Driven Integration of Software Systems
    (York)
  6. Software Safety Cases Establishing a Systematic
    Approach (York)
  7. Dependability Explicit Metadata (Newcastle)
  1. Dependable Use of FPGAs (York)
  2. Analytic Techniques for the Predictability of
    Complex Systems (York)
  3. Application of SOA to Dependable Systems (IBM)
  4. Software Guidance for 00-56 (QinetiQ/York)
  5. Software Language Policy (QinetiQ)
  6. Managing the Complexity of FPGA Designs (SELEX)

Research to establish an appropriate measurement
infrastructure to support decision making,
including organisational practices and
information sharing.
Research to identify a balanced set of measures
to support key decisions in software systems
acquisition and trade-off analysis. The initial
focus is likely to be on general software process
measurement

Causes
Consequences
20
SSEI and Continued Airworthiness
  • Several relevant tasks
  • Software Safety Cases Establishing a Systematic
    Approach (Task 6)
  • Software Guidance for DS 00-56 (Task 11)
  • Dependable use of FPGAs (Task 8)
  • Evidence-Based Management (Task 2)
  • .

21
Software Guidance for DS 00-56
  • DS 00-56 Issue 4 is goal-based
  • Admits appropriate evidence and argument
  • For continued airworthiness, build on
  • Evidence of operation (operational data)
  • Evidence from development (where available)
  • Evidence of change management
  • Guidance will address combination, balance,

22
Other Tasks
  • Software safety cases
  • Longer term view
  • Evidence-based Management
  • Informed decision-making, reflecting balance of
    risk and benefit
  • Dependable use of FPGAs
  • Including processor replacement

23
Contents
  • Establishment of the SSEI
  • Current SSEI Programme
  • SSEI Future Developments
  • Conclusions

24
SSEI Development
  • Second phase of MoD research funding
  • Balance between themes
  • Address omissions
  • Open call, probably late third quarter
  • Additional services
  • Technical support, e.g. assurance, mentoring
  • Initially high integrity and safety critical
    applications

25
Technical Strategy
  • Comprehensive analysis of
  • Defence requirements, e.g. defence industrial
    strategy
  • Predictability of development time and cost
    should be accurate to 10
  • New systems should be developed in the same time
    and cost, despite a predicted 5-fold increase in
    complexity
  • Industrial needs, and assessment of industrial
    software development trends
  • Capabilities and tasks for each theme

26
Focus for Technical Strategy
  • Technical Strategy comprehensive, but too
    extensive to fund, hence need for prioritisation
  • So-called hard-problems
  • Challenges which will deliver military benefit,
    if the research is successful
  • Identified route through to exploitation
  • Give focus for work in the five themes

27
Hard Problems
  • Focus on six problems (TBC)
  • Supporting legacy
  • Secure system interoperation
  • Safety assurance at military tempo
  • Assurance of open systems
  • Model-based development
  • Integrated engineering management
  • All have a technical and managerial element

Supporting Legacy
  • Capabilities include
  • Legacy integration
  • Control/predicting emergent properties
  • Dependability/property trade-offs
  • Assessment and acceptance
  • Product maturity assessment
  • Planning engineering management
  • Some new tasks, contingent on next call

30
Additional Services
  • Offering to be developed, covering
  • Acquisition support
  • Training and mentoring
  • Development of guidance
  • Specialist input to MoD policy
  • Assistance with technology transfer of non-SSEI
    research results (capabilities)
  • Focus on high value-added activities

31
Long Term Objective
  • After initial research programme
  • Stable independent organisation
  • Not dependent on core MoD funding
  • SSEI a key player in a global network
  • Focus for work in the UK
  • Arbiter of quality, but not sole source for
    advice
  • International collaboration, e.g. DMO
  • Remit broader than defence, e.g. OGD

32
Contents
  • Establishment of the SSEI
  • Current SSEI Programme
  • SSEI Future Developments
  • Conclusions

33
Conclusions
  • SSEI focused on an important problem
  • Need for national capability
  • But must work internationally, e.g. SEI DMO
  • Engagement with SSEIAP
  • SSEI has many challenges, especially
  • Building critical mass
  • Achieving independent status
