From Process Architecture to Toolchain Architecture: Modelling the Resources that Enable Engineering Work

In the previous article, I discussed how model-based approaches can be used to capture engineering processes as connected structures of roles, activities, artefacts, responsibilities and information exchanges. Traditional process documentation often describes what should happen. A model-based process architecture can go further by representing how…

From Process Documentation to Process Modelling: A Model-Based Approach

By Hélder Castro Architecture, MBSE

Engineering organisations often define their processes using documents, flowcharts, spreadsheets and review templates. These artefacts are useful, but they often remain disconnected from each other.A process may be described in one document. Responsibilities may be listed in another. Artefact templates may sit in a separate…

A practical MBSE development built on templates for clear architecture decisions

By Hélder Castro Arcadia, MagicGrid, MBSE

System architecture models are rarely challenged because they are wrong; they are challenged because they are hard to navigate, hard to scope, and hard to review consistently.Reviews often fail not due to technical gaps, but due to unclear expectations: what should exist, in what order,…

An Introduction to Model-Based System Engineering (MBSE) and model value

By Hélder Castro MBSE

Motivation for System Engineering Whether it is an advanced military aircraft, a hybrid vehicle, a cell phone, or a distributed information system, today’s systems are expected to perform at levels that were unimaginable a generation ago. Competitive pressures demand that these systems utilize technological advancements…
