What is MODAF?
What is MODAF?
• MoD Architectural Framework– Based on DoDAF (US)– Approach for the design of complex systems (NEC)– Enables Interoperability
– Models Enterprises
Coping with complexity
• Models future systems – Aids requirements specification– Produces interlinked conceptual models– Provides overview– Provides operational focus
• Uses– Abstraction / Decomposition / Categorisation– Separation of issues into Views– Standardised representations: Structure/UML
• Supports collaboration between different disciplines– Provide common reference– Aids design management and trace

Organisational & Social
HFI Functions
• HFI creates value through: – Raising potential issues and preventing risks– Establishing validated insight– Providing methods, processes, data, standards, expertise– Enabling user involvement– Undertaking a design mediation and communication role

HFI support for MODAF
Why and How
• Why integrate HFI with MODAF? – SE needs HFI
• Enable socio-technical systems design• Need to specify people-related design decision areas
– Explicitly; Correctly; Early
– MODAF (version 1.0) has shortfalls in that
– HFI needs SE• MODAF is now mandated • Coping with design of complex systems• Opportunity for early involvement
• How? – Human Views (HVs):• Model human-related elements of Enterprises
• Ensures common modelling approach• Helps HFI to relate to SE concepts/methods
MODAF (version 1.0) shortfalls
• HFI trends and standards • are not captured.
• Human performance metrics, targets, and limitations • are not specified.
• Human role/job/organisational design • is insufficiently captured.
• Allocation of function decisions/ information requirements specifications
• may be technology-lead. • Team activity and team requirements
• are insufficiently captured.
