Interview
(Interview of Mr. Nazim Hussain to discuss the problems of the current system and the improvements for the new system)
Q1. What are the advantages of the current system?
Every customer has its own membership number therefore it is easier to find out who has not given the film back.
Q2. What are the disadvantages of the current system?
It takes too long to find a particular film or DVD and lot of space for the manual records is wasted.
Q3. What changes do you want in the current system?
I want a new computerized system to be much faster and reliable than the current system, which will reduce the problems being faced. i.e.: amount of time it takes to locate a particular film.
Q4. What changes don’t you want in the new system?
I still want the membership numbers and I want the customer’s information sheet laid out on the computer in the same way as it was laid out on the manual register because the information is easier to follow.
Q5. What are the user’s I.T skills and knowledge?
I am a computer literate and I have a good basic knowledge of excel
Q6. How do you want your work to be protected on the computerized system?
To prevent anyone to have access to the new system the user will have a special password. All the information should have a backup copy, incase any information is lost or is destroyed due to any viruses.
Investigation
The current system
Presently Movie Box is working manually and the business is dealing with the following inputs:
- Name
- Address
- Contact numbers
- Membership number
- Date of rental
- Date the movie or the DVD is due back
Processing:
- How much revenue is coming in weekly
- The cost of the movie or DVD
- Filling in the register daily of the rentals being taken out
Output:
- Information about rented videos and DVD’s is written on paper
- Prices received for every video rented
The Current System
Below is a flow chart of how the current system rents out movies or DVD’s
Input:
Below is an example of a form filled in by the assistant as each customer rents out a video. (This is done manually)
- Name
- Address
- Contact Number
Type of film- Bollywood or Hollywood
- Date the movie or DVD is taken out
- Date the movie or DVD is due back
- Title of film
- Cost
Sign of customer……………………
- Membership number
- Time
- Date
- Deposit
Sign of assistant……………………
Problems with the current system
- A lot of time is wasted as everything is recorded manually
- Too much paper work means, there is not enough space in the register as most of the information is more likely to go astray
- Mistakes are more likely to be made as calculations for the weekly incomes are done manually and not by a spreadsheet
- Difficult to search for particular type of information as everything is not in a order
- The register in which everything is recorded has a chance of getting and information in the register can look scruffy and hard to read.
Customers Dissatisfaction
- The customers can not take the movie or DVD out because the assistant is not sure whether it is in or out of the store. Most movies are hardly seen by the customers because they are not recorded in the register
- Searching for a particular film wastes the customer’s time
- Long process, for the customer. As every time the customer comes to the store, he/she has to wait until the assistant records the customer’s details manually again.
General Objectives
Qualitative Objectives:
- I am going to design a new computerized system that is much quicker and reliable than the current system, which will reduce the problems being faced
- The new system should be easy to use by the end user (Mr. Nazim and his assistant)
- Using this assistant will make it harder for the assistant to make mistakes e.g. calculations for the weekly incomes will have a special formula and it will be done on a spreadsheet that will be able to print many copies and do the task quicker
- To prevent anyone to have access to the new system the user will have a special password
- Data entered must be easy to perceive and comprehend by all the members of staff
- Taking movies or DVD’s should be much easier
- Look-up functions and validation rules must all work
- Information and details about certain movies or customers can be found easily by going to the customer’s list
- All information must be saved on the hard drive and must have a backup, incase any information is lost or has been destroyed due to viruses
Quantitative Objectives
- The system should have limitless capacity, as there is a lot of information about customers and movies as well as DVD’s
- Movies and DVD’s should be taken out and returned back in less than five minutes
- Calculations should not take more than two minutes to work out
- The extra fee charge should come up automatically on the screen if the film is kept for more than a day
- The programme should be straight forward and easy to use
- The assistant should have their own password to log in so no one access customer details without authorization
