Companies are unable to find software that really support their activities. Instead they use standard applications that are not designed for their specific company, nor capable of adapt to changes within the company.

During my Thesis project I tried to find a way to simplify the development process, to be able to develop usable and adaptable business software.

The company TE Johnston was used as a use-case to test if a solution could be developed to fit their specific company.
