Our development methods for producing bespoke applications
Two methods, two specific solutions to your requirements:
- Agreement on a budget by the client
- Setting up of a backlog made of user stories
- Prioritisation of developments and regular deliveries
- Approval of a quote based on precise specifications
- Delivery at the end of the development
This more traditional method works by approving a quote with defined specifications and delivery dates. Your project is delivered in full at the end of the development phase, which is estimated at the outset.
How we apply the Agile methodology
in our daily development
Since 2012, our group has been using the AGILE Methodology for its developments, which is an organization of work in short cycles. It allows the integration of developers in the primary stages of projects..
A team expert in web technologies: Asp.net MVC, Angular JS, Wep api and React
A team specialized in “heavy client” technologies and server development: Wpf, xaml, window form, c++.
A Research & Development team to enable us to be constantly innovative and at the forefront of the latest technologies.
The AGILE method allows development teams to manage a project in a flexible way and to be able to adapt to unexpected events. The feedback is fast on the code produced and this allows them to deliver solutions that meet the expectations of customers.
Our solutions are all developed following this organization, which allows us to involve our customers in the development process. This method ensures us a greater reactivity to our customers’ requests and thus an increased satisfaction.
