The improvement of software processes plays an important role in the developing of systems that obtain a higher quality product. Redesigning software takes a considerable amount of time. Even making a small change is a difficult task and it takes a long time to obtain better results. Moreover, if the software tools that help this change are not properly managed, the improvement in the development of the System could be stopped. This paper presents a process of changing a web system which uses an initial complex design to another one that uses a simpler and improved development tools such as the ZK and Hibernate Framework, which final result is indeed improved Software.
