Every idea is a new Start

My concept is the holistic view from the idea of the project to implementation. At the beginning of each project, the basis for success or failure will be determined. It will be developed on the software requirements and objectives.
The result is an accurate description of the idea and includes the layout and functionality.

Success is determined by the user

Success is defined by the added value to the users of the software solution. He can choosing in a wide range of software solutions. He thinks self-centered and uses exactly the software that brings him the greatest benefit.
Therefore, in all my projects, the end-user is the center and is involved in all phases of development with. Only then is it possible to bridge the gap between the demands and a software solution.

When the idea comes to life

It is important that the user can perform its tasks with little effort. In order to give the user the feeling to have the best solution for his problem, a strategy needs to be developed. The solution should solve more issues than it creates.
For this reason, we always start in developing the user interface and going down to bring the function to life.
