tailieunhanh - Activity 6.4: Modeling Dynamic Behavior

Dynamic models provide the development team with a detailed picture of the relationships of use cases and usage scenarios. The models provide current state descriptions of the workflow processes and important task sequences. In this activity, you will develop activity, interaction, and state models for the Ferguson and Bardell, Inc. case study. | Activity Modeling Dynamic Behavior Dynamic models provide the development team with a detailed picture of the relationships of use cases and usage scenarios. The models provide current state descriptions of the workflow processes and important task sequences. In this activity you will develop activity interaction and state models for the Ferguson and Bardell Inc. case study. Objectives After completing this lab you will be able to Use models to describe dynamic behavior in the business environment. Before You Begin This activity consists of small group tasks and class discussion. To complete this activity you will need the Ferguson and Bardell Inc. case study and the use cases and usage scenarios you developed in Activities and . Time to complete this activity 50 minutes followed by a 15-minute class discussion 52 Activity Modeling Dynamic Behavior Exercise 1 Developing Activity Models Develop activity model for the timesheet system 20 minutes 1. Work in small groups assigned by the instructor. 2. Review the case studies sections that describe the timesheet and data entry systems. 3. Identify the use cases that describe the flow of activities from the consultant creating the timesheet to the final invoicing of the client. 4. Describe the workflow process in an activity model in the following table. Use case Relationship Use case Activity Modeling Dynamic Behavior 53 Exercise 2 Developing Interaction Models Develop an interaction model for the timesheet system 20 minutes 1. Identify a critical use case in the timesheet system. Choose one where problems occur often. 2. Develop the usage scenario for the use case. 3. Identify the sequence- and message-based interactions in the usage scenario. Use Case Actor System Usage Scenario Precondition Post condition Task Sequence Behavior Task .
