Instructor Notes Module 6: Business

Solution Physical Design

Introduction

In this module, students will learn about the basics of physical 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 also learn how the process of developing a physical 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 physical design in the process of designing a business solution

! Describe the role of physical design in the MSF Design Process

! Describe the steps of physical design

! Create a preliminary services topology

! Identify the risks in conflicts between solution requirements and physical constraints

! Complete the activities

Activities

Activity 6.1: Risks of Skipping Physical Design

In this activity, students will participate in a class discussion to identify the possible risks are of not completing a physical design in the process of designing a business solution

After completing this activity, students will be able to:

! Articulate the value of doing physical design and the risks of not doing physical design

! To prepare for the activity

1 Complete the activity yourself, thinking through the possible directions that the discussion may take

2 Prepare examples from your own experience

3 Prepare some questions to foster a class discussion

Activity 6.2: Risks in Constraints and Requirements

In this activity, students will participate in a class discussion about the implications of the constraints and requirements in the Ferguson and Bardell, Inc case study

After completing this activity, students will be able to:

! Articulate the type of risks that become evident when requirements are not aligned with the physical constraints of the solution

! To prepare for the activity

1 Review the Ferguson and Bardell, Inc case study

2 Create some new requirements and constraints to add to the case study

3 Complete the activity by using the new requirements and constraints

Think through possible ramifications of the additional information on the case study and its solution

4 Prepare some questions to foster a class discussion

Activity 6.3: Determining a Preliminary Distribution of Services Across a Network Topology

In this activity, students will create a preliminary plan for distributing services across a network topology

After completing this activity, students will be able to:

! Create a service topology by distributing services across the network topology

! To prepare for the activity

1 Prepare extra copies of the business-object model created in Module 5, in case some students do not have their copy

You can use either the class consensus business object model or distribute the one from the suggested solution

2 Complete the activity yourself

3 Remind students of the services-based design approach of Module 3 This approach consists of the user, business, and data services that exist between the user interface and data store

Module Strategy

Use the following strategy to present this module:

! Physical Design Basics This section provides an overview of the Physical Design Phase of the MSF Process Model Having worked through the conceptual and logical phases, students may have a “Finally!” attitude to reaching this phase Help them to understand that physical design is still not coding, but is the final

preparation to that coding, and that the quality of work they do in this last design phase will have a direct impact on the coding work itself

! Risks of Skipping Physical Design This discussion enables you to gauge the students’ understanding of the necessity and benefits of physical design

! Physical Design Process This section provides an overview of the physical design process, including its place within the MSF Process Model This section also outlines the steps and deliverables of physical design

! Physical Design Research

In this section, students learn about the research step of physical design Emphasize that the step takes the solution requirements and constraints and identifies the gaps and conflicts between them Also emphasize that the project team must consider the current enterprise architecture This step must be grounded in reality, with no fudging of either the requirements or the constraints Finally, examine the concept of trade-offs, and be prepared with real-life examples of the various ways of dealing with gaps

! Risks in Constraints and Requirements This discussion will enable you to gauge how well the students understand the importance of the research step of physical design Use the discussion to support the content of the section

! Physical Design Analysis This section teaches students about the analysis step of physical design Emphasize that this step delivers proposed topologies and candidate technologies In many development projects, such analysis is done in a fairly informal manner You should help students understand the necessity

of following a formal, yet flexible, process Remind them of that the MSF Design Process encourages traceability throughout the design Help them to also understand that at this point, the business and user requirements are still the primary consideration Additionally, continue to remind them of the iterative nature of the design process

! Determining a Preliminary Distribution of Services Across a Network Topology

In this activity, students will develop a preliminary distribution of services across the network topology from the Ferguson and Bardell, Inc case study This is a fairly simple process of determining where the user, business, and data services will reside Because this might seem trivial to some students,

be prepared with questions and options for how the services might be distributed
