Why MoDAF

To Support Complex decision making process, may affect whole business.

What is MoDAF• Modaf is a specific set of views of an enterprise.

• MODAF provides a coherent set of rules and templates, known as Views, that, when populated, provide a graphical and textual visualisation of the business area being processing

• Architectural modellers who need guidance on the creation and interchange of MODAF views (including for example: architecting principles, view coherence rules and tool selection criteria)

• Each View offers a different perspective on the business to support different stakeholder interests.

The Views are divided into 7 categories:

• Strategic Views (StVs) define the desired business outcome, and what capabilities are required to achieve it

• Operational Views (OVs) define (in abstract rather than physical terms) the processes, information and entities needed to fulfil the capability requirements

• Service Oriented Views (SOVs) describe the services, (i.e. units of work supplied by providers to consumers), required to support the processes described in the operational Views

• Systems Views (SVs) describe the physical implementation of the Operational and Service Orientated Views and, thereby, define the solution

• Acquisition Views (AcVs) describe the dependencies and timelines of the projects that will deliver the solution

• Technical Views (TVs) define the standards that are to be applied to the solution

• All Views (AVs) provide a description and glossary of the contents of the architecture

• “NEC is the linking of sensors, decision makers and weapon systems so that information can be translated into synchronised and overwhelming military effect at optimum tempo.”

• NEC is about joining up the business and battlespace

• Enables us to federate systems, sensors, effectors and hence improve military effectiveness

– Projects and programmes now link and overlap.– Multiple operational, technical and service

boundaries emerging, which must be managed coherently.

• Without change, we run the risk:– Advantage of inefficiency - project activities

wrongly phased, reproduced or repeated.– Dis-Advantage of major performance gaps

overlooked, or emerging late in acquisition, requiring expensive remedial action.

Architectures and Architectural Frameworks

Architectures and Architectural Frameworks

Architectures:• “A formal description of a

system … at component level to guide its implementation”

• “The structure of components and their interrelationships”

• A set of views that describe system(s) of interest at a certain point in time

Architectural Frameworks:

• “A tool which can be used for developing a broad range of different architectures.”

• “Provides a common vocabulary”

• Provides a basis for comparing and analysing architectures

Why are we using MODAF?Why are we using MODAF?• By providing a common “language” to describe

MoD business it:– Gives a means of managing across all lines of

development / through life– Allows the identification of overlap, duplication, gaps– Enables unambiguous requirements that enhance

interoperability– Provides commonality and rigour to MoD processes– Provides improved contextual information on the systems

to the approving authorities

• All of which allow more efficient use of the budget and delivery of enhanced capability

MODAF ViewsMODAF Views• MODAF is based upon DoDAF but with

tailoring to MoD lifecycle / processes and as a result of US and UK lessons learned

• Most DoDAF views will be incorporated largely as-is with tailoring to MoD terminology, ERM, etc

• Some DoDAF views may be modified to incorporate lessons learned

• Two new viewpoints included:– Strategic Views – mainly support capability

management– Acquisition Views – support the acquisition

MODAF DevelopmentMODAF Development• Will utilise existing DoDAF products

where possible• Similar documentation approach to

DoDAF –executive summary, handbook, desk book

• Will develop progressively with multi-stage stakeholder reviews to minimise surprises and volume of new material at each stage

• Using white papers as discussion documents prior to integrating the full MODAF product set

• Central equipment customer is overall project manager

• Core funding for framework, enablers and aspects of governance

• Training & population activity costs outside scope

• Federated approach to change• Approved target is validated MODAF

MODAF Meta Model• SysML

– Modelling language for systems engineering– Key Concepts:

• Activity: concept for modelling behaviour• Assembly: concept for modelling structures which have

behaviour

• MODAF Meta Model– Consistently models a complex system of systems– Extends SysML with concepts applicable to

modelling an enterprise– Focused modelling of operational, system,

implementation and programme viewpoints
