In this milestone, you will prepare a Request for System Services Form, which is the trigger for the Preliminary Investigation Phase. Also, you will use fact-finding techniques to extract and analyze information from an interview to determine project scope, level of management commitment, and project feasibility for the Equipment Check-Out System (ECS). With these facts and facts obtained from the Case Background, you will have the necessary information to complete the Problem Statement Matrix. Refer to the ECS Case Introduction in the Case Project page.
Objectives
After completing this milestone, you should be able to:
• Complete a Request for System Services form, which triggers the preliminary investigation phase.
• Analyze a user interview and extract pertinent facts, which can be used to assess project feasibility.
• Complete a “Problem Statement Matrix documenting the problems, opportunities, or directives of the project.
Prerequisites
Before starting this milestone, the following topics should be covered:

There’s an old saying that suggests, “Don’t try to fix it unless you understand it.” With those words of wisdom, the next milestone of our project is to study and analyze the existing system. There is always an existing business system, regardless of whether it currently uses a computer. The problem analysis phase provides the project team with a more thorough understanding of the problems, opportunities, and/or directives that triggered the project. Indeed, the analyst frequently uncovers new problems and opportunities. The problem analysis phase may answer the questions, “Are the problems worth solving?’’ and “Is a new system worth building?’’

PROCESS MODELING- Part I Synopsis
The requirements analysis phase answers the question, “What does the user need and want from a new system?” The requirements analysis phase is critical to the success of any new information system! In this milestone we need to identify what information systems requirements need to be defined from the system users’ perspectives.
The Data flow diagram (DFD) has gained popularity as a technique for expressing system requirements for two reasons:
• It facilitates development, which often leads to building systems that better satisfy user needs
• Data flow diagrams and narratives are easy for users to understand.

In this milestone you will first uncover external agents, processes and data flows that define the requirements for the proposed system and document that information. You will use that to build the Context Data Flow Diagrams.

DATA MADELING Part I (Logical ERD)
The requirements analysis phase answers the question, What does the user need and want from a new system The requirements analysis phase is critical to the success of any new information system! In this milestone we need to identify what information systems requirements need to be defined from the system users perspectives and draw graphical, logical models to document the data requirements for a new and improved system.
Data modeling is a technique for organizing and documenting a system s data. Data modeling is sometimes called database modeling because a data model is usually implemented as a database. Data is viewed as a resource to be shared by as many processes as possible. As a result, data must be organized in a way that is flexible and adaptable to unanticipated business requirements and that is the purpose of data modeling.

Synopsis
1. Level 0 Data flow Diagram
Objectives
After completing this milestone, you should be able to:
1. Create a Level 0 (System) Data Flow Diagram
2. Create a Child Data Flow Diagram
Prerequisites

Before starting this milestone, the following topics should be covered:
• Process Modeling - Chapter 9
Assignment
As a systems analyst or knowledgeable end-user, you must learn how to draw data flow diagrams to model business process requirements. The preliminary investigation and problem analysis phases of the methodology have been completed and you understand the current system’s strengths, weaknesses, limitations, problems, opportunities, and constraints. You have already built the Context models (Milestone 3) to document business requirements for the new system. You now need to build the Level 0 (System) DFD and corresponding process models.

Activities
1. Develop Level 0 DFD. Make assumptions where necessary.
2. Draw one Child Diagram using the Level 0 diagram.
3. Continue decomposition of one process up to primitive processes (Level 2, Level 3, etc.)
Deliverable format and software to be used are according to your instructor’s specifications. Deliverables should be neatly packaged in a binder, separated with a tab divider labeled “Milestone 5-Part II”.

MILESTONE 5 - Process Modeling - Part III (User Interface)
Synopsis
Management and users make important decisions based on system outputs. Outputs present information to system users. Outputs, the most visible component of a working information system, are the justification for the system. These outputs are produced from data that is either retrieved from databases or, more often, input by users.
Good input and output design can make the difference in whether or not an information system is used effectively. User interface design provides a roadmap or dialog that integrates the inputs and outputs.
In this milestone you will design outputs, inputs, and user interface for the Customer Response System.
