Activity 10.1: Creating and Distributing
Preliminary Components
In this activity, you will place candidate components into service layers
assigned in a previous activity.
Objectives
After completing this activity, you will be able to:
!
Create a preliminary component topology by distributing preliminary
components across the network topology.

Before You Begin
This activity includes both small group tasks and class discussion.
Prerequisites
To complete this activity, you must have completed the activities for modules 5
and 6.
Materials
!
The Future Corporate Network Topology provided in the Ferguson and
Bardell, Inc. case study.
!
The business object model created in Module 5
!
The service layer topology created in activity 6.3
!
Flip chart.
!
Self-stick notes.
!
Markers.

Time to complete this activity: 20 minutes followed by a 10 minute
discussion.
86 Activity 10.1: Creating and Distributing Preliminary Components



Exercise 1: Creating Preliminary Service Type Based Components
(10 minutes)
!
Create preliminary components
1. Participate in small groups as assigned by the instructor.
2. Review the business object model created in Module 5.
3. For each business object, break its high-level services into the appropriate
service types.
For example, the high-level service Authorize Card could be broken down
into a specific user service, business service, and data service.
4. After all high-level services have been decomposed into their appropriate
service types, create preliminary components for each business object by
packaging the different services of each type into separate components.
For example, the Invoice business object would have an Invoice User
Services component, an Invoice Business Services component, and an
Invoice Data Services component.

Exercise 2: Distributing the Preliminary Components (10 minutes)
!
Distribute the preliminary components

1. Participate in small groups as assigned by the instructor.
2. Distribute all the preliminary components based on user services according
to where you have identified users services on the topology in Exercise 1.
Be aware of possible component redundancy.
3. Distribute all the preliminary components based on business services
according to where you have identified business services on the topology in
Exercise 1.
Be aware of possible component redundancy.
4. Distribute all the preliminary components based on data services according
to where you have identified data services on the topology in Exercise 1.
Be aware of possible component redundancy.
5. Choose a team representative to present the preliminary component
topology that you have just created.

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