Instructor Notes Module 5: Business
Solution Logical Design
Introduction
In this module, students will learn about the basics of logical design, where it
fits in the Microsoft
®
Solutions Framework (MSF) Process Model, its purpose
and value in solution design, its steps and tasks, and its outputs and
deliverables. Students learn how the process of developing a logical design will
enable them to deliver solutions that match their customer’s requirements.
After completing this module, students will be able to:
!
Explain the need for a logical design in the process of designing a business
solution.
!
Describe the role of logical design in the MSF Design Process.
!
Describe the steps of logical design.
!
Identify the principles of modular design.
!
Assess the impact of implementation considerations on the logical design.
!
Design the objects and services of a business solution.
!
Derive a logical design for a business solution from a conceptual design.

Activities
Activity 5.1: Risks of Skipping Logical Design
In this activity, students will participate in a class discussion to identify the
possible risks of not completing a logical design in the process of designing a
business solution.
After completing this activity, students will be able to:
!
Articulate the value of logical design and the risks of not completing a
logical design.

!
To prepare for the activity
1. Complete the activity yourself.
2. Prepare examples from your own experience.
3. Prepare some questions to foster a class discussion.

Activity 5.2: Identifying Business Objects and Services
In this activity, students will identify the business objects and services
contained in the scenario that the instructor provides.
First, they will analyze the usage scenario for potential business objects. These
candidate business objects are the logical constructs that help identify the
services, attributes, and relationships of the future solution.
Next they will analyze the usage scenario for potential services.

In this activity, students will continue to analyze the selected future-state usage
scenario, focusing on the business object attributes and relationships.
First, they will identify the attributes of the business objects.
Next, they will identify the relationships between the business objects.
After completing this activity, students will be able to:
!
Analyze a usage scenario and determine candidate business object attributes
and relationships for use in the solution design.

!
To prepare for the activity
1. Complete the activity yourself.
2. Review the suggested solution.
3. Prepare examples from your own experience.
4. Prepare some questions to foster a class discussion.

Activity 5.4: Logical Design Verification
In this activity, students will participate in a class discussion to identify
methods of refining and verifying the logical design.
After completing this activity, students will be able to:
!
Articulate methods of validating a logical design.

!
To prepare for the activity
1. Complete the activity yourself.
2. Prepare examples from your own experience.
3. Prepare some questions to foster a class discussion.

Analysis: Business Objects and Services
A detailed discussion of business objects and services is in this section.
Take your time working through this section because many students may be
unfamiliar with the concepts. Have a number of examples prepared.
Be careful not to let the more experienced students try to move to physical
objects; emphasize that this is still logical design, and that they should not
yet be considering the development or implementation.
!
Activity 5.2: Identifying Business Objects and Services
This activity provides students with the opportunity to work in a team
environment on the logical design of the solution to the Ferguson and
Bardell, Inc. case study.
!
Analysis: Attributes and Relationships
This section completes the analysis step. By this time, students should be
beginning to understand the concept of business objects and their services,
attributes, and relationships. The “parts of speech” comparison
(objects=nouns, services=verbs, attributes=adjectives) may be helpful to
some.
Take a few moments at the end of the section to gauge the class’s grasp of
the concepts by presenting examples and having students analyze them.
Emphasize that the quality of the analysis done in this step will have a direct
impact on the quality of the physical design to follow.
