Architectural Modelling / Architecture Description

Creating architecture models (or an architecture description) of systems or parts of systems is a useful mechanism for

  • understanding the context in which the system-of-interest exists
  • 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 e.g. avoiding the classic “law of unintended consequences”
  • 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.

In more recent times we’ve been producing architecture descriptions as graphs using the Neo4J graph database to enable better and easier querying / use of the model content and the relationships to extract meaning and results.
