| Objective |  |
The Milestone Assignments are based on the Projects and Cases for use with the Systems Analysis and Design Methods textbook by Whitten & Bentley.
There are six (6) parts to the Project, consisting of twelve (12) milestones. During Weeks 2-7, you will be required to complete two (2) milestones. Each milestone is worth 40 points. Milestones 5 and 10 are included as already completed work, so you only need submit them as part of the assignment.
| Guidelines | |
Be sure to read the Project area of each Assignment section, as they talk directly to the milestone tasks. Also, for review purposes, note that typical milestone solutions will be posted on Wednesday morning of the following week. This is necessary as it is important for you to observe your errors as you further build on your cases. Note: Once milestone solutions are posted, no late work can be accepted.
Client Technology Tracking System – Case Introduction
The milestones will be graded based on how well they convey the needed information, use of tools and techniques for the section involved, and timeliness of submission.
Note: Please upload your completed assignments to the Dropbox as directed. Please be sure to submit BOTH milestone assignments to the Dropbox using ONE Word document. (Also, please paste created diagrams and illustrations from other software—like Visio—into this document.

- Problems, Opportunities, Objectives, and Constraints Matrix
- Tentative List of Functional and Non-Functional Requirements
Review all of the Milestone project steps below. Post questions in the CTTS Milestone discussion area.
Milestone 1
The purpose of the preliminary investigation phase is threefold. First, it answers the question, “Is this project worth looking at?†To answer this question, this phase must define the scope of the project and the perceived problems, opportunities, and directives that triggered the project.
In this milestone, you will prepare a Request for System Services, 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 Client Technology Tracking System (CTTS). With these facts and facts obtained from the Case Background, you will have the necessary information to complete the Problem Statement Matrix.
For this milestone, you will be using the following templates/resources:
Note: Please be sure to submit BOTH milestone assignments to the Dropbox using ONE Word document. (You may paste created diagrams and illustrations from other software as needed.)
Milestone 2
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?”
The purpose of the problem analysis phase is threefold. First and foremost, the project team must gain an appropriate understanding of the business problem domain. Second, we need to answer the question, “Are these problems (opportunities and directives) worth solving?†Finally, we need to determine if the system is worth developing. The problem analysis phase provides the systems analyst and project team with a more thorough understanding of the problems, opportunities, and/or directives that triggered the project. In the process, they frequently uncover new problems and opportunities.
In this milestone you will perform a cause-effect analysis on the Client Technology Tracking System (CTTS) and document your findings using the Problems, Opportunities, Objectives, and Constraints Matrix. The PIECES framework, originally developed by James Wetherbe and then adapted by the authors, can serve as a useful tool to classify the various problems, opportunities, and directives identified in Milestone 1.
For this milestone, you will be using the following templates/resources:

| Part 2 of 6: Milestones 3 & 4 (80 pts.) – Due Week 3 | |
Be sure to read the Project area of each Assignment section, as they talk directly to the milestone tasks. Also, for review purposes, note that typical milestone solutions will be posted on Wednesday morning of the following week. This is necessary as it is important.
Deliverables:
- Use-Case Glossary
- Use-Case Model Diagram
- Use-Case Narrative
- Entity Definition Matrix
- Context Data Model
- Key-Based Data Model
- Fully Attributed Data Model
Review all of the milestone project steps below. Post questions in the Milestone Virtual Lab Forum discussion area.
Milestone 3
Use-case modeling has gained popularity as a technique for expressing system requirements for two reasons: (1) it facilitates user-centered development, which often leads to building systems that better satisfy user needs, and (2) use cases diagrams and narratives are easy for users to understand.
In this milestone, you will first uncover the actors, use cases, and relationships that define the requirements for the proposed system and document that information in a Use-Case Glossary. You will use that to build a Use-Case Model Diagram for the system and a Use-Case Narrative for one use case.
For this milestone, you will be using the following templates/resources:
Milestone 4
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.
In this milestone, you will first discover those entities in the system that are or might be described by data. Then we will define each entity we identify in respect to the business. Then we will construct a Context Data Model that graphically depicts each of the entities and their relationships with each other. Next, we will refine the context data model to include primary and foreign keys. The resulting model is called a Key-Based Data Model. Finally, we refine the key-based data model to include any hierarchies and attributes, and this model is referred to as the Fully Attributed Data Model.
For this milestone, you will be using the following templates/resources:
