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’o No manufacture, no raw material, no cost to replicate & delivero Potential for rapid, safe upgrade – not yet realised

■ Software problems are not easily absorbed because ofo Complexity – unintended side effectso Integration – extensive side effects

■ Software science, technologies methods and tools arenot stable or mature – e.g. aerospace:o 70’s, 80’s – Functional design + assembler + custom h/wo 80’s, 90’s – Object Oriented + HOL + COTS h/wo 90’s, 00’s – Model Driven + COTS o/s, h/w

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

Perception of Defence Software Systems

■ Failure to meet specification

■ Expensive

■ Always late

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 bidderso IBM, MBDA, AeI, QinetiQ, YorkMetrics, SEIC, EDS,

Insyteo Universities of York, Newcastle, Loughborough,

Oxford

■ Mixture of basic and applied research tasks plus an enabling contract for ‘additional services’

Research Themes

Current Status

■ Initial Research Programmeo Understanding the problemo Identifying potential solutions

■ Agreed Technical Strategyo MOD endorsement

• SIT, DE&S, DSTLo Industry endorsement

Next Steps

■ Call for further research proposalso Based on Technical Strategyo Joint Industry/academia

■ Process for additional serviceso Trial run of processo Establish credibility/value added

• Rapid exploitation of research outputs

■ Growth in SSEI membershipo Coreo Associates

What Will Success Look Like?

■ SSEI has established itselfo Centre of Excellence in the UK for Software Systems Engineering

• Provides leadership• Coherent Industry and Academic capability• Working beyond Defence• A developing body of case studies

o Diversity of funding• MOD• Wider Government• Industry

o Recognised body for SSE accreditation • Individuals • Organisations

o Expanding range of services offered

SSEI Research Programme

■ Programme has five themeso Management, especially evidence basedo Architecture, including SoSo Integrationo Dependability, e.g. safety and securityo Properties

Initial three year programme funded, with 13 tasks

Engagement possible via Special Interest Groups (SIGs)

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)

8. Dependable Use of FPGAs (York)

9. Analytic Techniques for the Predictability of Complex Systems (York)

10. Application of SOA to Dependable Systems (IBM)

11. Software Guidance for 00-56 (QinetiQ/York)

12. Software Language Policy (QinetiQ)

13. Managing the Complexity of FPGA Designs (SELEX)

Research to establish an appropriate measurement infrastructure to support decision making, including organisational practices and information sharing.

SSEI and Continued Airworthiness

■ Several relevant taskso Software Safety Cases – Establishing a Systematic

Approach (Task 6)o Software Guidance for DS 00-56 (Task 11)o Dependable use of FPGAs (Task 8) o Evidence-Based Management (Task 2)o ….

Software Guidance for DS 00-56

■ DS 00-56 Issue 4 is goal-basedo Admits “appropriate” evidence and argument

■ For continued airworthiness, build on o Evidence of operation (operational data)o Evidence from development (where available)o Evidence of change managemento Guidance will address combination, balance, …

Other Tasks

■ Software safety caseso Longer term view

■ Evidence-based Managemento Informed decision-making, reflecting balance of risk

and benefit

■ Dependable use of FPGAso Including processor replacement

Contents

■ Establishment of the SSEI

■ Current SSEI Programme

■ SSEI Future Developments

■ Conclusions

SSEI Development

■ Second phase of MoD research fundingo Balance between themeso Address omissionso Open call, probably late third quarter

■ Additional serviceso Technical support, e.g. assurance, mentoringo Initially high integrity and safety critical applications

Technical Strategy

■ Comprehensive analysis of o 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”

o Industrial needs, and assessment of industrial software development trends

o Capabilities and tasks for each theme

Focus for Technical Strategy

■ Technical Strategy comprehensive, but too extensive to fund, hence need for prioritisation

■ So-called “hard-problems”o Challenges which will deliver military benefit, if the

research is successfulo Identified route through to exploitationo Give focus for work in the five themes

Hard Problems

■ Focus on six “problems” (TBC)o Supporting legacyo Secure system interoperationo Safety assurance at military tempoo Assurance of open systemso Model-based developmento Integrated engineering management

All have a technical and managerial element

Fragment of Prioritisation Table

Problem Supporting Legacy Secure System Interoperation

Success Criteria Ability to preserve operational capability by providing ongoing support for legacy software

Ability to assure secure services across different management domains

■ After initial research programmeo Stable independent organisation

• Not dependent on core MoD fundingo SSEI a key player in a global network

• Focus for work in the UK• Arbiter of quality, but not sole source for advice

o International collaboration, e.g. DMOo Remit broader than defence, e.g. OGD
