Our application development methodology.
We support you at every stage of your project. Our exclusive turnkey development methodology, built on the principle of continuous innovation, covers functional design, visual and technical design, programming, testing and fixes, all the way through to training, deployment, security and maintenance of your web and mobile application.
Discover the method.webp)
A unique method, proven across hundreds of projects.
We support you at every stage of your app project to drive it to success through a cycle of continuous innovation (discovery / design / delivery), from design to deployment and maintenance.
Functional, visual and technical design
We support you at every stage, from functional design to striking visual design and the build of a solid technical architecture for your solution.
01Project study
The project study covers any audit of the existing setup and benchmarking, research and advisory, and the listing of the specifics of the product to be built along with its functional specifications (user stories) within the functional and design brief.Start your project02Visual design & prototyping
Visual design covers persona and experience research, visual identity and brand guidelines, wireframes and high-fidelity mockups (UX/UI design), wording, and high-fidelity interactive prototyping.03Technical design & architecture
Technical design covers the creation of the mind map, the application architecture (UML diagrams, flowcharts, tech stack and structure tree), the technical development brief, and the project initialization (preparing for programming).
Programming, testing and fixes
We support you at every stage, from programming to rigorous testing and the adjustments and fixes applied to your solution.
04Programming
Programming covers the coding of the various products planned in the brief (mobile app, business software, SaaS, CRM, ERP, back-office) on both the frontend and the backend, along with various technical optimizations (load performance, security rules, etc.).05Technical acceptance (MOE)
MOE acceptance covers technical testing (architecture, integration tests, component / data tests, etc.) as well as functional testing (feature conformity, end-to-end scenarios, interface tests and stress tests, 100 to 200 test cases depending on the project, etc.). Any anomalies detected are fixed.06Client acceptance (MOA)
MOA acceptance covers functional testing carried out by you and your testers to verify the conformity of the delivered product(s) and apply any necessary fixes or adjustments. This phase ends with the signing of a UAT (User Acceptance Test) sign-off.
Training, deployment, security and maintenance
We support you at every stage, from training to public deployment, including the security and maintenance of your solution to ensure its long-term success.
07Training & support
Training and support cover a complete walkthrough of your admin console (back-office), such as data consultation, user identification and search, updating user information, etc. We also provide a PDF document and support for any questions.08Public deployment & verification
Once your solution reaches the maturity of the targeted version, we proceed with its public deployment to your production environment and app store(s): App Store, Google Play Store and the web. We then carry out an initial verification and apply a 6-month corrective maintenance period included (free of charge).09Security & maintenance
Security and maintenance cover the protection and supervision of your solution through compliance, technology watch, the setup of alerting and notification systems (24/7 cloud monitoring), and finally corrective, preventive and evolutive maintenance (time-and-materials or fixed-fee).
Step-by-step
project tracking.
Step-by-step project tracking.
From design to deployment, your Project Manager ensures rigorous tracking through daily check-ins, and stays available for any question about how the project is delivered by our teams.
