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…

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.

Logical Architecture: How to Perform Arcadia MBSE – Step-by-Step Illustrated Examples

By Hélder Castro Guides

The principle of the Logical Architecture (LA), commonly called logical architecture, starts to “open the box” by implementing the big decisions of the solution, in terms of principles of construction, and ways to fulfil the expectations of stakeholders.

Physical Architecture: How to Perform Arcadia MBSE – Step-by-Step Illustrated Examples

By Hélder Castro Guides

This perspective defines the finalized architecture of the system, as it should be completed and integrated. It adds the functions required by the implementation and technical choices and reveals the behavioural components that perform these functions.

MBSE with Arcadia data modelling

By Hélder Castro Guides

An important part of system engineering involves ensuring consistency, correctness and completeness between the data managed in the system and the data exchanged with external actors, and components. In order to, unambiguously describe these exchanges, the data, information, matter flow, etc., must be formalized. An…
