Question

Task # 3:          Identify Functional and Non-Functional Requirements for the given system description:

The proposed software product is the Hospital Patient Info Management System (HPIMS). The system will be used to get the information from the patients and then storing that data for future usage. The current system in use is a paper-based system. It is too slow and cannot provide updated lists of patients within a reasonable timeframe. The intentions of the system are to reduce over-time pay and increase the number of patients that can be treated accurately.

General Description:

Product Perspective

This Hospital Patient Info Management System is a self-contained system that manages activities
of the hospital as Patient Info. Various stakeholders are involved in the hospital patient info
system.

Product Functions

The system functions can be described as follows:

 Registration: When a patient is admitted, the front-desk staff checks to see if the patient
is already registered with the hospital. If he is, his/her Personal Health Number (PHN) is
entered into the computer. Otherwise, a new Personal Health Number is given to this
patient. The patient’s information such as date of birth, address and telephone number is
also entered into computer system.

 Patient check out: If a patient checks out, the administrative staff shall delete his PHN
from the system and the just evacuated bed is included in available-beds list.

 Report Generation: The system generates reports on the following information: List of
detailed information regarding the patient who had admitted in the hospital

User Characteristics:

The system will be used in the hospital. The administrators, front-desk staff will be the main
users. Given the condition that not all the users are computer-literate. Some users may have to be
trained on using the system. The system is also designed to be user-friendly. It uses a Graphical
User Interface (GUI).

 Front-desk staff: They all have general reception and secretarial duties. Every staff has
some basic computer training. They are responsible for patient’s check-in or notification
of appropriate people.

 Administrators: They all have post-secondary education relating to general business
administration practices. Every administrator has basic computer training. They are
responsible for all of the scheduling and updating day/night employee shifts.

General Constraints

 The system must be delivered by January 1st 2011.

 The existing Telecommunication infrastructure is based on IEEE100802.3 standards and
the system must conform to this standard using category 5 cables for networking

 The system must be user-friendly

Assumptions and Dependencies.

 It is assumed that one hundred IBM compatible computers will be available before the

system is installed and tested.

 It is assumed that the Hospital will have enough trained staff to take care of the system
