Review
When you’re closely involved with the preparation and issue of a document it can be hard to really see what is written. This is a human trait and it also happens in other areas such as modelling when we describe what we think it ought to be rather than what we’ve actually committed by definition either on paper or in electronic forms or using languages such as SysML, UML or indeed anything.
This is why independent review is essential to the rigour of the design process, not just in the realms of safety, (and why marriage counsellors et al exist!).
Eclectica Systems can support
- review and analysis of individual documents
- review, participation (i.e. design review panel member) in classic systems engineering design reviews
- System Requirements Review (SRR) - focus on the requirements, flow-down/relationships, structure and management
- System Definition Review (SDR) - focus on the programme, allocation, technical approach & adequacy
- Preliminary Design Review (PDR) - focus on adequacy of design against requirements and operational concept (e.g. CONOPS, CONUSE, CONEMP), risk, safety,
- Critical Design Review (CDR) - focus on adequacy of detailed design
- Test Readiness Review - suitability/fitness for purpose to undergo test

Architectural Modelling
Creating architecture models (or an architecture description) of systems or parts of systems is a useful mechanism for
- discovery - uncovering facts that either weren’t know or weren’t expressed
- definition - defining boundaries, behaviour/function/structure
- describing - providing a systematic description of a system, its dependencies and place in the bigger world
- communicating - having a visual representation is a good way of promoting communication and debate and often easier to understand than tabular or straight text (Mk1 Human seems to be highly evolved for visual information processing)
- integrating - following on from the above it provides easy ways of involving the various domain experts to distill the knowledge into the one model or architecture description
Eclectica Systems has been involved in (enterprise) architectural modelling for many years now having been involved with the MoD before the MODAF (MoD Architectural Framework) came into existence and subsequently with the Integration Authority (IA - now the SEIG) Architecture Lab at Malvern. This has involved modelling of diverse things such as
- large naval platforms such as Astute or land platforms such as FRES
- C4I systems such as RNCSS, JOCS, JC2SP
- the definition of the makeup of the Recognised Air Picture (RAP) and Recognised Maritime Picture (RMP) - in order to then understand and evaluate the systems that work with or impact on these
- national and technical standards and their dependencies - for project standards review
More recently Eclectica Systems Ltd has been developing architectural models for the UK rail domain and has developed an architectural framework, TRAK, based on MODAF for London Underground Limited.
We’re even sufficiently sad to be experimenting with how to represent UK Rail, Research and Strategy through architectural modelling.
