The Object-Oriented (OO) paradigm represents a significant shift in approach to the development of complex software systems. The OO approach provides a very natural solution, where entities in the system have close association with the problem domain. However the application of the approach suffers from a major draw back - the lack of well defined methods for visualizing objects which map well to the problem domain. The very first activity of object identification itself has for a long time been more of an art than science. Object identification in the case of some problem domains (like communication network protocols etc.) is even more difficult as they are more abstract and cannot be easily related to the real world objects. The proposed method SESAME (Scenario Event State Action MEthod) builds a solution to the problems based on events that occur in the system. whether they are generated by people. machines or components of the software. It approaches the problem domains by looking at scenarios which are characterized by events, states, and actions. This approach helps in adopting an organized way of visualizing the entities that need to participate in the system. Abstraction of these entities into objects will then be relatively simple. The SESAME method features a comprehensive Analysis and Specification activity which comprises of building an Object Behavioral Model (OBM) and a Class Specification Model (CSM). The analysis is taken through by tracing the events and their responses in every visualizable scenario.
