Question Description

Assignment 4 -- Interaction Models


The purpose of this assignment is to continue our ITOT Case Study modeling by creating an SSD (System Sequence Diagram) and a Detailed Sequence Diagram.

You will add an SSD (System Sequence Diagram) and a Detailed Sequence Diagram based on your detailed use case for Manage Shopping Cart. You will also need to refer to your class diagram and activity diagram or detailed use case steps. This will complete the Analysis Specification for the IT Online Training Case Study. See the list of Resources at the end of this assignment for details on the two types of sequence diagrams and activity diagram.

In this assignment, you will complete the following sections in your Analysis Specification

Sections 6, 6.1, 6.2


1. Review the resources listed in the Quick Resources below on Sequence and Activity diagrams.

2. Create an SSD (System Sequence Diagram) based on your detailed use case, "Manage Shopping Cart".

2.1 Use your CASE tool to create the SSD and add it to Section 6.1 of your Analysis Specification from Week 3. Add a discussion of your SSD.

3. Create a Detailed Sequence Diagram based on your detailed use case, "Manage Shopping Cart".

3.1 Use your CASE tool to create the Detailed Sequence Diagram based on your detailed use case and add it to Section 6.2 of your Analysis Specification from Week 3. Add a discussion of your Detailed Sequence Diagram. Remember that the Detailed Sequence Diagram adds the actual objects required to the sequence diagram instead of just :System.

4. Complete Section 6 of your Analysis Specification and make any corrections you need to other models.

Submission Instructions

1. Submit your updated Analysis Specification as a Word file.

2. When you submit your Word file, use your name as part of the file name, e.g., ENTD321Assignment4_FirstNameLastName and make certain that your name and course number are at the top of the file.

Your assignment will be graded with the following rubric:
