SYSTEM ANALYSIS

Requirement specification and expected outcomes

The reason of me producing this system is to be able to generate estimated prices of the hire of a car for LIA Car hire service which is based is based in Luton Airport. Luton Airport has decided, after lots of consideration, they need to expand their services at the Airport. They have decided to open a hire service for Cars. They have everything ready and now all they need is a model which will be able to generate estimated prices for each Car Hire. I have been given this job. The main reasons of wanted a model which will generate the estimated prices is so the system operator will not have to go through all of the calculations and things. If there was not a model which would generate the figures it would be very complicated and very easy for there to be a mistake. The model will generate the prices with formulas. There will be fewer chances of mistakes, it will make the work easier for the operator, and the customer will get a quick estimate of how much they are looking at paying.

The users of my system will be the System Manager, his or her job will be to update the system whenever they are needed e.g. if any variable data changes. The system manager will have all the passwords so he will be able to change what ever he or her like whenever. The operators job is to ask all of the necessary details needed for the system, when this is done there will be an automatic Invoice created, all the operator will have to do is take two print outs of that and give one to the customer and keep one for the companies records. All the customer will have to do is tell all the details needed to the operator, e.g. what car he or she wants, pay method and so on. The system will all be password protected so the operator is not accidentally able to change any of the formulas or any other details.

The information will be presented to the system operator on screen, the customer will receive a printout of the Invoice, and the company will keep one print-out of the invoice for future references. All of the hires will have to go through the manager. To generate the system there will be lots of information needed from the customer, like personal, financial and the vehicle details. I had to decide which pieces of details will be the most important, these are the pieces of information I decided will be very important or crucial for the hire to proceed :-

The Invoice will be produced automatically from the model. No one will have to touch the invoice all they will have to do is press the print button. The way I will do this by just using the important information from the model and placing it one the invoice. So whenever it changes on the final model it will also change on the invoice. The way to do this on Microsoft Excel is to start of the ...
