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. Materials and Preparation This section provides you with the materials and preparation needed to teach this module.

Instructor Notes Module 5: Business Solution Logical Design 3 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. Finally, they will extend the analysis to identify hidden objects and services. After completing this activity, students will be able to: ! Analyze a usage scenario and determine candidate business objects and services for use in the solution design. ! To prepare for the activity 1. Prepare extra copies of the case study for students who may not have their copy with them. 2. Prepare enough copies of the usage scenario for the class. The class could use the consensus usage scenario from Module 4 or you can supply the usage scenario from the suggested solutions. 3. Obtain flip charts, markers, and self-stick notes adequate for the number of students in the class. Note that these materials are also used in subsequent activities, so students will need to adjust the amount needed upward to accommodate the requirements of all the activities. 4. Complete the activity yourself. Be sure to think of alternate answers that the student teams may perceive and be prepared to discuss the merits of such alternative answers. 5. Review the suggested solution. 4 Instructor Notes Module 5: Business Solution Logical Design 6. Prepare examples from your own experience. 7. Prepare some questions to foster a class discussion. Activity 5.3: Identifying Attributes and Relationships 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. Instructor Notes Module 5: Business Solution Logical Design 5 Module Strategy Use the following strategy to present this module: ! Logical Design Basics This section provides an overview of the Logical Design Phase of the MSF Process Model. Because many development organizations proceed directly from research to physical design, the concept of an intermediate, logical design may be difficult for some students to grasp. Some students may also be unfamiliar with the concept of business objects. (Avoid any discussions of Object Oriented Programming (OOP) objects. The discussion in this course is about “business objects” and not objects in the OOP sense.) Take your time laying the foundation in this section and be prepared with some simple examples of logical design. Be sure to emphasize the risks of skipping logical design, particularly in complex projects. ! Activity 5.1: Risks of Skipping Logical Design This discussion will enable you to gauge how well the students understood the previous section. Use this opportunity to clarify any confusion that might remain. ! Logical Design Process This section is a simple overview of the logical design process, including the two steps of analysis and rationalization. Because the term “analysis” was used in conceptual design, some students might be confused. If necessary, take a moment to outline all the steps of the three phases of the MSF Design Process so that students can grasp the flow and also see that terms are used more than once. ! 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. 6 Instructor Notes Module 5: Business Solution Logical Design ! Activity 5.3: Identifying Attributes and Relationships In this activity, students will identify the attributes and relationships of the business objects from Activity 5.2. ! Logical Design Rationalization Some of the concepts in this section are more advanced than in the previous sections. Issues of verification, coordination, and control may be difficult for students to grasp. Be sure that you have a good understanding of the concepts and try not to get bogged down in this section. The goal of the previous sections was to provide students with the basic knowledge and steps on which to build. This section builds upon that base knowledge by introducing additional design concepts. You may be moving the students outside of their comfort zone, so keep examples in mind to clarify these concepts. ! Activity 5.4: Logical Design Verification This discussion will enable you to gauge students’ comprehension of the final step of logical design, as well as their understanding of the Logical Design Phase. As with all discussions, it will be easier to foster a discussion if you have questions prepared beforehand. .
