Blue Water Estate Agent (BWEA) - design a computer based system

Extracts from this document...

Introduction

Analysis Identify the Problem The Blue Water Estate Agent (BWEA) is situated in Finchley, North London. It has good publicity from its sponsor, Clear Blue Contact Lenses. Many people go to the estate agent for good service. They get many offers from the local area. These are usually successful and good for the business. Nature of the Problem Estate Agents are paid to sell houses to the right customers. They need to know which type of houses, customers want. They must price the house according to the features of that particular house. Sales will keep changing and prices will vary. The problem with the Estate Agent is that they do not have a sufficient way of recording sales and prices that are constantly changing. They also need to send out letters to customers efficiently and as fast as possible. Currently, with the present system, a house is put on sale buy the seller. The Estate Agents show the property to the buyers who would be interested. They know what type of property the buyers are looking for because they fill out forms on questions about the different houses available. Then, a viewing time is arranged which is suitable for both seller and buyer. If the property is chosen, the buyer offers a price. The seller either accepts of declines the offer. If accepted, the property is sold; otherwise the property is put back on sale. This system is very gradual and takes time for it to happen. This is mainly because there is no quick way of advertising the property without a computer. A website is usually a key point in advertising for Estate Agents as the customer can look at the residences and choose the most suitable one. They can also view the information of the property on the Internet. The problems with the present system are: * Writing could easily be misread as a result of unclear handwriting. ...read more.

Estate Agents contact the customer For the Estate Agents * Details about the house * Details about the customer * The current system at the estate agents * The type of advertising currently used * The ways of contacting the customer * Ways of collecting information * Updating information in the Estate Agents We found out the above. Other alternatives we could have used to collect information are: I could have written letters to customers as an alternative asking them about the current system of the Estate Agents. They would have replied with a letter through the post. I could have also interviewed the users for answers I could have met with them and collected the information directly. The advantages of the questionnaire are that all the answers required are very clear. All the questions are usually answered in a questionnaire. The disadvantage of using a questionnaire may be classed as junk mail. The user may not bother to post the answers back. The advantages of using letters are that you can explain fully in writing why you are asking for information about the Estate Agents. It is personalised for the user, unlike junk mail. It can also be very polite to the user. The disadvantage of using letters is that some people might not have time to reply. Not all of the questions might be answered which are required. The advantage of using an interview is that you can collect the information instantly. You can ask all the questions required and all the questions will be answered. The disadvantages of an interview are that a lot of time is needed for the interview. People might be unwilling to go for an interview.
