Customers' needs become the center of attention and the service is adapted to address their needs. The more specific the required service, the more specialized the software solutions have to be.

However, frameworks alone don't solve all the problems. The construction and use of frameworks is so highly complex that software developers are confronted with almost insurmountable difficulties. The article, describe the problems encountered, and the concepts and techniques used to overcome them. The presented approach supports the development of frameworks and systems that are both stable and capable of evolving elegantly at different speeds
