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

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,…

How to perform Capella–IBM DOORS 9.x round‑trip synchronisation for textual requirements: step-by-step guide

By Hélder Castro Capella, Guides, Textual Requirements

This guide describes step-by-step how to export and import textual requirements between IBM Doors 9.7 and Capella modelling tool. The below figure shows the initial process considerations when authoring textual requirements and designing the system in Capella: Textual requirements and Capella traceability modelling process For…

Simple Process for Architecture Development with MagicGrid

By Hélder Castro MagicGrid, Matrix step-by-step, Video

When a new Model-Based System Architecture (MBSE) model or during the system architecture modelling development, stakeholders involved or with an interest on, may ask and express different understandings and modelling expectations: What modelling activities and artefacts content should be produced? What are the artefacts relationships…

Understanding what is the MBSE Arcadia method

By Hélder Castro Arcadia

ARChitecture And Design Integrated Approach (Arcadia) is a structured engineering method for defining and verifying the architecture of complex systems.

MBSE with Arcadia step-by-step guide and practical example

By Hélder Castro Arcadia, Guides, Matrix step-by-step

The Arcadia method is a Model-Based Systems Engineering (MBSE) approach structured around abstraction layers to support the development of complex systems. This guide explains Arcadia step-by-step — from Operational Analysis through Physical Architecture — with a focus on what each layer means, what activities are…

Operational Analysis: How to Perform Arcadia MBSE – step-by-step illustrated examples

By Hélder Castro Guides

This perspective analyses the issue of operational users, by identifying actors that have to interact with the system, their goals, activities, constraints, and the interaction conditions between them.

System Analysis: How to Perform Arcadia MBSE – Step-by-Step Illustrated Examples

By Hélder Castro Guides

This perspective focuses on the system itself as a black box, in order to define how it can satisfy the former operational needs. This perspective builds an external functional analysis, which is constructed based on the operational analysis and textual input requirements and outlined with respect to them.
