In this chapter, the authors use the methodology presented in Chapter 2 to develop a system that manages the spreading of organic waste on agricultural parcels. The proposed method uses a process of iterative and incremental development. Two complete iterations of the development process are presented starting from the analysis model and ending with the code produced by the case-tools Structured query language code generator. The first iteration deals with the description of territory objects and the second one deals with the business objects used in the context of the spreading of organic waste. As a result of transformations applied, models are enriched with new concepts and, therefore, are more complex. The growing complexity of the model may negatively affect an actor's understanding, which may become an impediment by slowing down the analysis phase. The authors show how the software development process model, a modeling artifact associated with the continuous integration unified process method, avoids the apparent complexity of the model and improves productivity.
