Our Development process
The project idea is developed and finalized together with the client. In the next step, the concept is written down in the form of an epic/user story. This document contains all the requirements for the final module.
The user story is evaluated in terms of content and structure by the various development departments. The department head receives cost estimates and information about personnel resources.
Requirement <br />
Our development department works out the module according to the user story. The sprint cycles are based on your preferences. Depending on the company structure, the sprint cycles usually last between 2-4 weeks.
Test & Approval
The testers approve the module and test it for errors and defects. If any are found, the module goes back to development, which fixes the problems. Once the tests pass without errors, the module is deployed.
