    Sequence diagram is a conceptual schema for representing behavior of a system. For performing such a task, it employs the object spec from a scenario and the sequence of messages exchanged among the objects. These elements describe a transaction of the system. Several approaches try the automated generation of conceptual models (like sequence diagram). Some of them use natural language as a starting point, but they are focused on other diagrams. Some others are focused on sequence diagram, but they do not obtain elements like combined fragments describing several logical constraints of the system. Other approaches use source code as a starting point, but source code can be related to an advanced phase of the software development life cycle. In this paper we define a method based on heuristic rules for obtaining automatically the elements of the sequence diagram (including combined fragments) from pre-conceptual schemas. These heuristic rules are implemented in the AToM3 tool and applied in a case study.

    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.
