Resumen en español

According to the Custom Development Method (CDM), the first phase of the software development process is commonly the definition phase. Processes related to the organization in which the software application is needed, problems that motivates the development process, and objectives associated with several organizational areas are determined in this phase. KAOS (Knowledge Acquisition Automated Specification) goal diagram is used in this phase to describe high-level organizational goals and then divide them into sub-objectives concerned with the stakeholder needs and expectations. Software Engineering group of the Escuela de Sistemas of the Universidad Nacional de Colombia developed a method to automate the KAOS goal diagram obtaining from Pre-conceptual Schemas, which are diagrams to describe the organizational processes and vocabulary linked with the software development. We use in this paper three case studies in order to validate such a method. The case studies are reported in specialized papers about this issue.
