01 — System architecture

The architecture that gives your projects the right impetus. Setting objectives at the start of the project ensures its success.

A vague or shifting architecture costs ten times more to correct mid-project. With our service, you leave with a solid technical foundation that holds up in front of your clients, partners and investors.

This service is right for you if …

You are starting a new project and want to build on solid technical foundations.
Your team is going in circles on spec definition or interfaces between domains.
The architecture has already been modified several times and the project is starting to drift.
You have a Gate Review or technical audit coming up in the next few weeks.
You have a clear product idea but lack the method to structure it into a system.
You need to credibilise your project in front of investors, clients or industrial partners.

Our approach

A sequential flow, from raw need to validated architecture

Stakeholder Requirements Collective scoping workshops and bilateral sessions with each domain (mech, elec, software) to capture real needs, constraints and stakeholder requirements. Supported by tools such as Jama.

Product Requirements We turn needs into clear, prioritised and verifiable product requirements. The Product Requirements Review is conducted in direct dialogue with your teams — a joint construction.

System architecture We structure your multi-domain system with Capella and the Arcadia method: operational, functional and physical views, defined interfaces, guaranteed overall coherence.

System simulation In parallel with the architecture, MATLAB/Simulink or SCILAB/Xcos models allow concepts to mature, performance hypotheses to be tested and requirement relevance validated before freezing decisions.

Design support & design reviews We support your teams throughout implementation: design reviews, technical arbitration, unblocking critical points. Mechanical, electronics, software and magnetic domains covered simultaneously.

Validation Verification of architecture compliance with defined requirements. Verification plan, prototyping, acceptance criteria, preparation of industrial reviews and technical audits.

What you receive

First deliverables arrive as early as the requirements definition phase. For longer projects, delivery follows the project rhythm: you have documents at each phase, before formal milestones if needed. Each document is produced in standard formats that your teams can take and evolve independently, with no dependency on Aquila.

Functional specification document — PDF/Word, ready to present to your partners and investors.
Jama export — stakeholder and product requirements, structured, prioritised, traceable.
Capella model — complete system architecture: operational, functional and physical views.
Architecture report — annotated diagrams, technical decision rationale, interface analysis.
MATLAB/Simulink simulation models — validated concepts and requirements; models are delivered to you.
Verification plan — acceptance criteria, test methods, requirements coverage.
Project planning / technical roadmap — milestones, dependencies, ready to manage your subcontractors.
Workshop minutes — full traceability of decisions taken in collective and bilateral sessions.

A coherent and solid set to convince an investor, precise enough for your team to start development the next day.
