Title of Project : Designing and development of Serdang Hospital Information Systems (SHIS)

Problem Statement

This is an informal specification of what hospital administrators want from you the company designing a system to help them manage their hospital efficiently and effectively.

General Problem Statement

Due to budget cutbacks and general concern for providing the best service possible to the public, Serdang Hospital would like to ensure that they are using their scarce hospital resources in the most efficient manner possible. With this in mind we would like you to design a system which will help them manage their hospital in an efficient, effective manner. Specifically the system should help them schedule and monitor the various resources that they have at the hospital. This includes keeping track of available beds, waiting lists for patients, patients expected length of stay, scheduling of surgeries, patient notification and billing, scheduling of nurses and doctors.

Specification

The SHIS must keep track of certain pieces of information required for operation of the hospital. Namely:

Physical Layout of Hospital

Report to me on “Sleepy Passengers”

Assignments must be handed in on time or at least on the stipulated date.

Extensions will only be given under exceptional circumstances and will only be granted if notification is received in writing.

Some reasons for not allowing extensions are:

· Extensions are unfair to those who have worked hard to deliver assignments on TIME.

· The lecturer cannot cover the solution until the last assignment has been handed in

· A late assignment in my subject would usually leads to late assignments in other subject, and leading to a deterioration in the quality of work submitted

· Rigid deadlines exist in the real working environment.

All assignment work should be substantially your own

Cheating or plagiarism will result in zero marks for the assignment, and may result in failing the subject or worse

All assignments must be A4 papers and bound firmly in the Project Report Cover clearly stated proper identification
