# ICT system analysis and modelling.

Extracts from this document...

Introduction

ICT Coursework Task 1b -  MODELLING

SYSTEM ANALYSIS

Requirement specification and expected outcomes

I had to produce a model which will be used for LIA Car Hire Ltd. It had to be able to intake customer details and financial information.

The users of the system will be the system manager and the operator working in the company.

The information will be presented on screen to the customer but also an invoice will be printed out for the customer if necessary.

The information that will be collected by the customers will be personal information, financial information and also vehicle information. This is such as name, age, address for personal. Price, rental charge etc for financial data and make, model, red, mileage for hire.

The invoice is produced when information is input on the final draft and it transfers the information on to the invoice draft.

The mileage cost was a simple equation =(F14*I9)which is the mileage total times by the price per mile. It was a simple formulas used to find out the mileage cost. Another formulas ised is shown below.

=IF(F11>1600,30,K10)*I12

 Hire Data Date Hired 13/01/2003 Insurance Costs 10 Price Per Mile £0.07 V.A.T 17.50% Rental Cost 25 Total Days Taken 14 Mileage Cost 70 Total Insurance Costs 140 Total Rental Costs 350 Sub Total 420 Total VAT 73.50 Total inc. VAT 493.50

This was used to find out the total rental costs. This formula is called ‘if command’. And does basically two sums in one. It basically mean if the f11 engine size is larger than 1600 then the price is 30 otherwise the times k10 25 by i12 total days taken which is 14.

Final model

Conclusion

SYSTEM EVALUATION

System improvements

I had to produce a model which will be used for LIA Car Hire Ltd. It had to be able to intake customer details and financial information. I did not have many problems whilst producing the model but I did have some obstacles on the way which I overcome. I could improve my model in many ways. I could have it more sophisticated so that users will enjoy using it and also by having more help option to the user to guide them on how to use the system. I could add more aspects on the model so it will make it more user friendly. I would do all of these tasks if I had more time to do so. I chose Microsoft excel to make my model as it was easy to use and I was familiar with the program. I think I need to learn to use Microsoft access as it has more features available on it to make my model better to use and make it user friendly.

On the whole my model was a success.
