At the end of this module, students will be able to:  Describe the four perspectives of the MSF Enterprise Architecture Model.  Describe the three phases of the MSF Design Process Model and explain how each phase relates to the planning phase of the MSF Process Model.  Describe the MSF Application Model. Materials and Preparation This section provides you with the materials and preparation needed to teach this module. Materials To teach this module, you need the following materials:  Microsoft® PowerPoint® file 1639a_05.ppt  Module 5, “Overview of Other MSF Models” Preparation To prepare for this module, you should: • Read all of the materials for this module. Presentation: 30 Minutes Activity: 0 Minutes iv Module 5: Overview of Other MSF Models Module Strategy Use the following strategy to present this module:  The MSF Enterprise Architecture Model This section introduces the MSF Enterprise Architecture Model. Topics in this section include: • MSF Definition of Enterprise Architecture This section presents the MSF definition of Enterprise Architecture (EA), including the organization business activities and the application, information, and technologies that support those business activities. • Four Perspectives: One Architecture Tell students that in the past, information technology (IT) professionals have not been encouraged to examine enterprise areas other than technology. Neither have professionals in other enterprise areas been asked to relate their activities to other groups, least of all to the IT domain. When asked about activities in another department, the typical reaction is, “That is not my group.” This insularity is not very useful to the enterprise quest for self-knowledge. Each perspective, whether it is business, application, information, or technology, has value, but a viable EA arises out of the way that these perspectives interrelate.  The MSF Design Process Model This section introduces the MSF Design Process continuum and describes the application of the design process to the MSF Process Model. Topics in this section include: • The MSF Design Process Continuum This section defines conceptual design, logical design, and physical design, and describes the MSF Design Process continuum as an iterative process. • Design Process Relationship to the Process Model This section discusses the relationship between design activities during the planning phase of the Process Model.  The MSF Application Model This section describes the key function of the MSF Application Model, which uses a services-based component design approach to build applications. Topics in this section include: • Function of the MSF Application Model This section describes the definitions, rules, and relationships, and services-based component design approach used by the MSF Application Model. Module 5: Overview of Other MSF Models v • The MSF Services-based Application Model The MSF Application Model uses a three-tier, logical model for designing multi-tier, distributed applications that include three broad categories of service: user, business, and data. The benefit of the model is that it establishes definitions, rules, and relationships that form the structure of an application. • Breaking the Traditional View This section compares the traditional, stove-piped services view to the three-tier, logical approach of the MSF Application Model. The module concludes with review questions that reinforce the module learning objectives. There is no activity for this module. Module 5: Overview of Other MSF Models 1 Overview  The MSF Enterprise Architecture Model  The MSF Design Process Model  The MSF Application Model At the end of this module, you will be able to:  Describe the four perspectives of the Microsoft Solutions Framework (MSF) Enterprise Architecture Model.  Describe the three phases of the MSF Design Process Model and explain how each phase relates to the planning phase of the MSF Process Model.  Describe the MSF Application Model. Slide Objective To provide an overview of the module topics and objectives. Lead-in In this module, you will learn about some of the other MSF models and where additional information is available for the models. 2 Module 5: Overview of Other MSF Models    The MSF Enterprise Architecture Model  MSF Definition of Enterprise Architecture  Four Perspectives: One Architecture The four perspectives of the MSF Enterprise Architecture Model relate to one another in a way that comprises one architecture for the enterprise. Slide Objective To introduce the topics presented in this section. Lead-in In this section, you will learn about the MSF Enterprise Architecture Model, including the architecture and benefits of the model. Module 5: Overview of Other MSF Models 3 MSF Definition of Enterprise Architecture  Describes the Organization’s Business Activities  Describes the Applications and Information That Support those Business Activities  Describes the Technologies That Enable the Applications and Information  Represents a Dynamic Environment at a Single Moment in Time The MSF version of enterprise architecture (EA):  Describes the organization’s business activities, including: • How products or services are delivered. • How the business interacts with its customers and suppliers. • The organizational structure. • Business processes.  Describes the applications and information that support those business activities.  Describes the technologies that enable the applications and information.  Represents a dynamic environment at a single moment in time. Slide Objective To present the MSF definition of enterprise architecture. Lead-in There are many definitions of enterprise architecture, but few cover the scope of what it really means. 4 Module 5: Overview of Other MSF Models Four Perspectives: One Architecture  There Is One Architecture for the Enterprise  The Value of the EA Is Not in an Individual Perspective, But in the Relationships Between the Perspectives Enterprise Architecture Business Business Application Application Technology Technology Information Information There is one, singular architecture for the enterprise. Each perspective has value; however, the value of the EA resides in how those perspectives relate to one another. The acronym BAIT is an easy way to remember the four-in-one concept of EA. Business is at the top because it drives the enterprise. Applications and information are the means to achieve the business goals and objectives of the enterprise. Technology is at the base because it is the foundation. The key to successful EA is the ability to see business activities through all four perspectives. Mature enterprise organizations that still experience problems can usually trace difficulties to a lack of understanding of business aspects that lie outside of one’s activity domain. The MSF model is significantly different from other models in that MSF deals with applications before information.  Planners analyze applications first so that information technology (IT) can be analyzed after the application perspective is tied to business goals and objectives.  Another important characteristic is that business is the driver of the EA, and technology is the base. There are four perspectives to EA: the business perspective, the application perspective, the information perspective, and the technology perspective. Slide Objective To present the four perspectives of the Enterprise Architecture Model. Lead-in This slide shows the four perspectives through which to view an enterprise organization, each different, but all related. Key Points Tell students that B-A-I-T is an easy way to remember the four perspectives. Referring to the illustration, the pyramid symbolizes the four-in-one concept of the MSF version of EA.
