    1.1AnalysisDescription of the problem

    Organization

    Trade Talk is a company owned by Mr. and Mrs. Chideme.

    Their services are helping people with bulk deliveries.

    They deal mainly with small businesses that dont havemeans of delivering goods to their customers and also with

    individuals who may need their assistance.

    Nature of the problemAfter an observation I made of the system that Trade Talk

    has for their account records I realized that they were very

    unreliable. Some of their customers were wrongly accused

    of not paying their accounts when in actual fact thecompany would have just lost, or misplaced their slips of

    payment. Customers have had to wait for long hours in the

    reception area for the employees at Trade Talk to locate

    their details so that their details are signed by management

    for proof of payment. This is very inconvenient for the

    customer and the company as the customer could just

    decide to terminate their account due to lack oforganization.

    1.5 Description of other proposed solutions

    Solution 1

    I would like to design a new computerized database system

    for the file keeping of the deliveries that is especially made

    for Trade talk. By using the system one will be able to

    delete and enter data very easily but they have to have the

    password to be able to access the data .if any data entry is

    incorrect an error message will then appear on the screen

    .for security reasons only those in the sales and deliveries

    department will be able to access the information in the

    system the passwords will be given to the heads of

    department. Also the account periods will be lengthened to

    a year. Basically the system I want to create will be very

    user friendly a custom made to fit the companys

    requirements.

    All the companies will have their own files and documents

    folders with a specific name therefore making it easier tosearch for data.

    Solution 2I could recommend a system that the company can buy for

    example Microsoft access with a ready made data base and

    very easy to use. But the disadvantageof this is you cant

    change anything about the system.So if it is not suitable there is nothing you can do about it.

    Therefore the proposed solution is solution 1 because if the

    company is not pleased with the way the system turns out

    they can change things about it to suite their requirements.

    1.6 Evaluation of Solution 2

    Advantages

    y The system is ready made and all you have to do ishire a programmer to install the systemy It is cheaper than getting a system especially designed

    for the needs of the company.

    y It will likely to be a popularly used system so it will beeasy to use and familiar to the employees.

    Disadvantagesy You might not be able to find a system that fits the

    exact needs of the company

    y Hiring a person to install the system might be moreexpensive than getting it especially designed

    y If you buy a system and it is not really fitting with theway the company operates then the company will not

    be able to change anything about the system and will

    have to buy a new system which will bring a loss of

    profits to the company.
