Activity 5.3: Identifying Attributes and Relationships

In this activity, you will continue to analyze the selected future-state usage scenario focusing on the business object attributes and relationships

First, you will identify the attributes of the business objects

Next, you will identify the relationships between the business objects

Objectives

After completing this activity, you will be able to:

! Analyze a usage scenario and determine candidate business object attributes and relationships for use in the solution design

Before You Begin

This activity includes both small group tasks and class discussion

This activity is a class discussion

Materials

! Ferguson and Bardell, Inc case study

! Future-state usage scenario from Activity 5.2

! Flip chart with candidate business objects and services created in Activity 5.2

! Self-stick notes

! Markers

Time to complete this activity: 40 minutes followed by a 15 minute discussion

34 Activity 5.3: Identifying Attributes and Relationships

Exercise 1: Identifying Business Object Attributes ( 20 minutes)

1 Participate in small groups as assigned by the instructor

2 Review the preliminary business object model

3 Review the future-state usage scenario

4 Analyze the usage scenario for business object properties

5 Write the related properties on a self-stick note

6 Attach the self-stick note to the appropriate business object

7 Extrapolate other attributes from the current list of business objects, services, and attributes that may not have been explicitly listed in the usage scenario

Activity 5.3: Identifying Attributes and Relationships 35

Exercise 2: Identifying Business Object Relationships (20 min)

1 Participate in small groups as assigned by the instructor

2 Review the future-state consultant usage scenario

3 Analyze the usage scenario for verbs that describe associations between business objects

4 Organize the self-stick notes on the flip chart such that the relationships can

be diagrammed

5 Either write directly on the flip chart or use another set of self-stick notes to indicate the relationships between objects

6 For interaction type relationships, it is important to note which services interact with which services as that will help later on during physical design

7 Determine if any new services or attributes are required to support the relationships identified above

At conclusion of this activity, you will have a rough logical model of one aspect

of the solution indicating the business objects, their attributes and services, and the relationships among the business objects

After completing the above steps, you will discuss your responses with the class The instructor will write the class consensus on a flip chart
