Objective: To develop a web server to help reduce phone call time for Doctors, Nurses and Administrative Personnel and to increase patient satisfaction by providing easier access to standard information.

The Cardiologist Group has hired you to develop Systems Requirements for a proposed web site that will perform the functions described above, including providing patients with the ability to schedule their own appointments. Patients will access the module by using their Social Security Number (SSN), which means that you need to access a database that has patient information including SSN and insurance information. First, the firm wants you to check to see if the patient has paid all his bills. If so, the patient can proceed, otherwise the patient should be given a message to call the billing department. Second, if the patient has insurance, a screen should appear presenting him with the insurance policy information and to ask the patient to verify it. If it is not verified, the patient should be asked to call the billing department. If the patient has no insurance, a screen should appear asking the patient how the bill will be paid. This verification or indication of payment method should be recorded in a database. If verification or indication is provided, the patient should be presented with a screen asking what type of procedure (stress test, EKG, ultra-sound, consult with doctor, etc. database with procedures) they are scheduling. After the patient selects one, a screen should present a calendar with open dates and times for a specified appointment (calendar database). Once the patient selects a time, a screen should appear asking the patient to verify the selected date and time, and to provide a phone number where they can be reached in case the appointment is cancelled or to remind the patient the day before the scheduled appointment. When the patient accepts the appointment and the transaction is recorded in the database.

1. Write a Systems Requirements Document

Include all the key elements and functions of the web site. While the template suggests categories that you need to fill in or change, you do not have to use every one of them. (Delete the categories you will not use.) Be sure to use function numbers based upon the Traceability procedures specified in the document. Begin your own Revisions Table. If you use the template, the Table of Contents and other WORD tables will update automatically as you add or delete categories that are named and formatted similarly. Otherwise, include a Table of Contents that you develop. Use short, simple sentences to describe the function. This is a not a novel!

Mostly, make sure that the requirements you write make sense. Someone should be able to read them, understand what the web site will do. A web site developer should be able to create the web site based upon your document without needing to ask questions.

Your requirements document should include the following diagrams and flow charts (see Chapter 5 in your textbook for examples) to describe the web appointment module:

Decide what databases you need to support the transaction and draw them in your diagrams. Use PowerPoint for the diagrams. While you dont have to use exactly the same symbols as the text book, you need to be consistent and indicate what symbol you are using for what purpose.
