Behavior Diagrams Definition: Behavioral models describe the internal dynamic aspects of an information system that supports the business processes in an organization. During analysis‚ behavioral models describe what the internal logic of the processes is without specifying how the processes are to be implemented. Later‚ in the design and implementation phases‚ the detailed design of the operations contained in the object is fully specified. Use case diagrams are behavior diagrams used to describe

2.3 Ishikawa diagram In 1960s‚ Professor Kaoru Ishikawa has introduced Ishikawa diagram. This diagram also called fishbone diagram or cause and effect diagram (Ishikawa 1976). Since this diagram is inception‚ it has gained tremendous of popularity to identify the root cause of the variety of problems (Hossen et al. 2017). Besides that‚ Ishikawa diagram often called as fishbone diagram is because it can help in the brainstorming to determine the possible cause of a problem and also sort the ideas

Both Class Diagrams and Use Case Diagrams are used in the requirements determination of object oriented development. Object oriented development is an approach to system development that uses the object as the basic unit of systems analysis and design. Use case shows the relationships among actors and use cases within a system. Class diagrams are widely used to describe the types of objects in a system and their relationships The purpose of Use case diagram is that it shows the interaction
