Creating an IT system for an electrical appliance shop.

Extracts from this document...

Introduction

Analysis Introduction Mr Gafoor Saab owns a video shop, which deals with electrical appliances such as Televisions, videos, satellites and digital receivers. His main part of the business is renting Video's and DVD's. As this part of the business is vastly growing He feels the urge to do something with his manual renting system that is not helping him keep track of rentals. Due to his age Mr Gafoor Saab has not got the memory that he used to have and keeping track of overdue rentals is a problem for him as he feels that he is loosing out. He requires a new system that will help him keep track of his business and his customers. Background / Problem Mr Gafoor Saab had a collection of videos that he recorded and bought. He started collecting classic Bollywood movies as a hobby, Gradually the number of movies kept on growing, when friends visited him they would see this collection and ask if they could borrow the movie, so he started lending them to friends. 12 years ago Mr Gafoor Saab lived on Whalley range, not many video shops were open so he decided to open a small video shop in his front room. As popularity through the Asian community grew so did Mr Gafoor Saabs business. Due to such vast growth he has had to keep up to date with technology, as he has started renting out DVDs. In order to keep his business running efficiently and effectively he urgently needs a solution to keep him up-to-date with the running of the business because the old renting system is not working for him, as he feels he cannot keep on top of the system. ...read more.

Middle

Overview Now looking back at the interview with Mr Gafoor Saab I can summarise what I have found out: * Mr Gafoor Saab runs his own business within a growing Asian community and needs to update his manual system * He buys his own videos. * His Shop consists of Hollywood, Bollywood and Pakistani Movies that he rents out to the community. * He keeps record of all videos (new and old) in a book, which he writes over in ink. * Each customer's details are taken each time they rent out a video. * Every weekend he looks for any overdue rentals manually. * He sends letters to the customers, fining them for overdue rentals and asking them to return the videos * His DVD renting system works exactly the same as the video renting. * He also has a selling side to the business and has difficulty remembering what is in stock. * He likes the simplicity of the system but finds it difficult to remember everything. Problems with existing system There are many problems within this present system: * Making sure that you don't misplace the loans book and all the other books containing details of rentals. This could lead to not recording details of customers and loosing out money. * There is no security toward the loans books; any one could alter the records. * Keeping track of overdue rentals is difficult as there is no printed list. The overdue letters are sent via inspection of the Loans book. ...read more.

Conclusion

Deal with the return process by: * Decreasing the no of videos on loan in the correct customer record in the customer file. * Removing the customer reference in the appropriate video record in the video file. Produce reports for the following: * Monthly income information generated by video loans. * Overdue video lists. * Full video lists. * Full DVD lists. * List of videos and DVD's out. * Selective lists based on actors. * Selective lists based on release date. * Selective lists based on genre. * Membership cards for new customers All of the above reports should take only a few minutes to print in either a sorted or selective fashion. Validate the loan by: * Checking that the video and customer exists. * Checking that the video is not already on loan. * Checking that the customer has not exceeded his maximum loan limit. * Checking that the customer is not under the age limit for a particular film.
