Selection, Investigation and Analysis

ORGANISATION BACKGROUND Spurwings Island is a hotel that accommodates people around the world. It is located in the midst of Lake Kariba. Its headquarters is in Namibia and it was later introduced in Zimbabwe in 2006. The hotel has been using a manual system of telephone and paper for booking rooms. A lot of paper is used and it is getting expensive to buy the necessary stationary. Processing and searching of a single person’s details may take up to 20 minutes as there are a lot of paper flows which is time consuming. When information is lost or damaged the clerk faces some difficulties of recollecting the information as there are no back up facilities provided by the system.The employees are increasing in number as a lot of paperwork has to be done. The profit of the hotel is turning into loss.

ORGANISATION CHART

Description of the current system

When a customer wants to book a room, the clerk first checks to see if there are free rooms. If there are free rooms he then enters the required customer’s records in the customer form required by the process. After that he updates the room file and also updates the customer file. Afterwards calculations are made and then the customer will be given a room number and keys and the customer record added to other records.

Investigation of the Current System

This process of gathering information is the most vital stage which brings full understanding of the system and the knowledge of the requirements needed for the system development process.If the areas that require development are identified it would be easier for the systems analyst to design the new system. The investigation will be done in stages and the following techniques are going to be used:

I nterview Questionnaires Record Inspection Observation

Interview

This process allows face to face communication with the employees and the employers to find out which area really needs development. These are done to collect information that is relevant and that may help the analyst. The responses that were obtained were noted down

Chief Executive OfficerThe CEO pointed out that he is losing customers due to the corruption or the loss of data.He also pointed out that the manual system is draining their profit due to errors in calculating or even entering the data.

Clerk 1He also pointed out that the work is tiresome. He also said that the work load increases everyday and he often misses breaks because of a huge workload.

Clerk 2This one complained about how a lot of paper in the office causes congestion in the bookings. He also stated thatinformation is often lost and also a lot of miscalculations have been made leading to very serious errors.

CustomerThe customer complained about how it would take about 30 minutes to book a single room. He also said that it was tiresome spending a lot of time in queues.\

Advantages of interviews

The analyst can ask for clarification on some points that may not be clear.Encourages good report between the researcher and respondent.

Nonverbal gestures like facial expressions can help the researcher to determine if the respondent is telling the truth

Information can be collected even from the illiterate since the respondent’s language could be used

First-hand information is collected The researcher can probe to get more information

Disadvantages of interviews

It is expensive since the researcher has to travel to the interview venue It is time consuming as more time is spent travelling and carrying out the interview Good interview techniques are required as failure may lead to disappointments

Biased information can be given since the respondent may not tell the truth

Questionnaires

These are documents with carefully crafted questions to be answered by the respondent by filling on the spaces provided. These are to be passed to the CEO, the clerks and to some of the customers. A questionnaire contains gap filling questions where the respondent is required to express his/her own feelings and guided questions where the respondent just chooses Yes or No, True or False or just by putting a tick on given options.

Advantages

They provide quick responses as they are answered quickly Questionnaires are relatively cheap means of gathering data from a large number of

people. Responses can be tabulated and analyzed and were also used so as to ascertain that any

problems with the system are identified and addressed in follow up interviews. Useful when the same information is required from all respondents Suitable when number of respondents is large

Disadvantages

Good questionnaires are difficult and time consuming to design They are restricted to Yes/No therefore one cannot probe to ask further Not all questions are answered The person can misinterpret questions leading to wrong answers very difficult to find

skilled

Observation

At this stage the analyst was able to view the actual sytem in operation. The researcher can even take part in operating the system. It is used when the researcher wants to see for herself how the system operates. The following observations were made:

It is a long process to book a room for a single person It is also a long process to calculate the total money needed People were crowding in the hotel making very long queues Customers were getting impatient and a lot gave up

Advantages of observation

First hand information is collected

Accurate information can be obtained Areas of interest can be observed The researcher can take part in operating the system thereby getting the insight on how

the system operates

Disadvantages of observation

People work differently if they feel that they are being observed, therefore inaccurate information can be collected

The researcher may not understand some of the activities being observed It is time consuming to collect the required information The researcher may interrupt some of the activities being done

Record Inspection

In this method the analyst will be scrutinizing system documents in order to solicit information. The following information was gathered during and after the process:

It was figured out that there were many records to be filled by each person It was also figured out that there were many fields to fill at each record Also a lot of records were duplicated

Advantages of record inspection

Accurate information is collected from system records Shows how data is collected within the system Shows the exact data that is collected Shows information that must be produced by the system First hand information is obtained Gives a good idea of the ways things are actually done rather than how they are supposed

to be done

Disadvantages of record inspection

It is time consuming to go through all system records Manual files can be tiresome to go through and some of the data may be illegible Confidential files are not given to the researcher Documentation may be difficult for an outsider to understand Some records may be relevant Problems with the current system

Through the investigation the systems analyst was able to identify the main problems:

Time ConsumingIt is very time consuming to book a single room for the customers. It is also time consuming to search for a single record to update it or maintain it

InsecuritySince the files are stored in cupboards they are prone to being attacked by rats or little insects hence information is easily damaged hence lost. Also a clerk might spill juice on a record hence biasing it

ErrorsMiscalculations are a major problem to the hotel since a lot of calculations have to be made on the cash received. Also there are errors in entering data and this can cause serious problems

No backupsData is often lost due to the flooding of files in the office. It is quite impossible to acquire the same data again since no back up data has been acquired.

Aims and objectives of the new system

The aims and objectives of this project are as follows

Improved Performance It provides an automated registration of customers thus storing information on the system

rather than using bulk files It obtains greater speed and accuracy in handling data and generating reports It automatically calculates all the bills and delivers all the issues and notifications for the

customers who are against some rules This system also attach to the system of the accounts clerk and other departments so that

they can access the information of a particular customer

Reduced costs The costs used in buying the necessary equipment from time to time will be low

compared to when stationary like papers and pens were used

Security Information stored will be secure and safe since the computer will make use of log in

forms. This will ensure that the information has limited access hence less prone to viruses or miscellaneous damages

Less time consuming Since the system will be computerized it is expected to be fast in entering, processing and

making out reservations

Data integrity Data will be correct and accurate since validation processes are held. The correctness and

accuracy of data is important since calculations have to be exact and correct also.

Provision of backup facilities The system will provide backups in case of disaster occurrence. Information in the

computer might get lost due to fires or drive failure so the proposed system is supposed to make periodic copies of the information for safety reasons

FEASIBILITY STUDYThis is a preliminary investigation the analyst conducted to find out if there is a need for a new system. It involves evaluation of systems requests from users and to determine if it is feasible to construct a new one. Feasibility study can be divided into two main categories :

a) Technical Feasibilityb) Economic Feasibility

Technical feasibility

This determines if the organization can obtain equipment and personnel to develop, install and operate the system. It also focuses on the software and hardware required to start the new system. The organization proved to have the necessary equipment to hire and start the new system

Hardware and software requirements

The organization currently has no computer at all. The system is going to be upgraded from start point. The items required are illustrated below

Hardware Items RequiredDesktop Computers 2Printers 2

Software Items RequiredOperating System 1Antivirus 1Programming Language 1Microsoft Office Package 1

Personnel Required

Programmers 2Operators 2

Specific hardware and software requirements

Hardware Requirements

Storage memory 200GB Local hard DiskThis will be used to store large number of records for future use and an external hard drive would be needed to back up the information

Laser Jet PrinterThis will be required for printing receipts to customers after booking a room. This is reliable as it saves stationary costs and also prints as many pages as possible per unit time

Installed memory (Random access Memory), 4GB This is required to temporarily store the records that the receptionist is currently working on

ProcessorSuch a high processor will be required to perform processors such as updating records from a file of say 1600 records and also searching a record of a particular customer

3 Cable Connectors RJ45,8pot hub,6 network cablesThese will be used to set up a network such that there will be communication between the reception and other hotel branches

Software requirements

Microsoft Office 2010 Professional PackageThis will be used for the documentation of the system using Microsoft word and also storing database of records using Microsoft Access

Windows 7 Ultimate Operating systemThis is the most reliable operating system that will fit to the available hardware and development software and also has got some facilities that will make the system understandable and user friendly. The operating system would be 128-bit which allows RAM with large storage capacity(4GB)

Microsoft Visual Basic 6.0This is the programming language that will be used to code program

Smadav 2015 Anti-Virus SoftwareThis is used for scanning as well as cleaning viruses found in attachments

Economic Feasibility

This is a cost-benefit analysis carried out to determine whether the benefits of the new system will outweigh the estimated cost in developing, purchasing, installing and maintenance of the new system.

A table can be designed to compare an estimate of the costs of the old system and the new system over the years and determine whether the benefits of the new system will outweigh the old system :

From the table above it is clear that the new system is better and more profiting than the old system as years go by. The new system might have used a lot of money in the first year but as years go by the costs are decreasing hence increasing profit to the company.

Alternative solutions

I. Off-the-shelf- This is software that is bought from a software vendor and is written with no

specifications

Advantages- It is generally a less expensive solution as the cost of developing the software is

shared across a wider customer base- It is possible to speak to other users of the package for their evaluation before

spending money- The software can be bought and installed right away- The software is tried and tested and likely to contain fewer bugs than the newly

written software

Disadvantages

- The software can be highly complex and will usually include large sections that you will never use

- It tends to be a compromise. By it's nature it is designed for many different types of users, each of whom will have different requirements

- As the software tends to be large and complicated it may take a long time to learn properly (some of the most asked for additions to later versions of Word were ones that already existed in the previous version!)

- You may have to alter the way that you work in order to fit in with the way that the software has been designed

- There will probably be operations that you require that you simply cannot do with the software

- If you have problems you are usually at the mercy of a large and faceless organization who may not be quite as concerned as you are if you have a major problem that absolutely must be fixed before tomorrow morning!

II. Tailor made software(Bespoke) This is software that is written to the specification of a particular organization or

customer

Advantages- It is designed to do exactly what the user wants- It has no unwanted features - It can be written to run on specified hardware- It can be integrated with existing software- There may not be a suitable software package of the market

Disadvantages- If you do not have the source code you are dangerously exposed and are

wholly dependent upon the developer's continuing existence and good will. - If you pick the wrong developer you could end up with an application that is

unstable, unreliable and full of bugs.- The investment required will usually be much higher than with packaged

software. This is usually the biggest reason for not going down the custom route - you need to undertake a business justification exercise and compare the costs against the expected benefits and commercial advantages.

- A large investment in time is required during the development process and a bespoke application will take longer to implement.

- It can be difficult to get support for bespoke software, unless the developers themselves offer support services.

III. Increasing workforce

More workforce can be employed so that the workload of the employees will be reduced. Receptionists should be increased since they are the ones who do most of the data capturing. Accountants should also be increased as they are also the ones who do most of the operations and also to calculate separate bills

Advantages

- Workload is reduced - Becomes more efficiency- Moral can be improved- Reduces the time used by the student standing in long congested queues

Disadvantages

- more labor expenses are incurred- Confusion can arise due to many workers doing the same job.

After considering all the methods mentioned above the analyst chooses Tailor made ( Bespoke Software) because it is reliable and the organization has the required equipment to use it

TESTINGWhen a new system is developed, it has to undergo rigorous testing before it is released. Typically it may undergo several phases of testing including:

Dry run testing: the programmer follows through the code manually using test data to check that an algorithm is correct. The technique is useful for locating run time errors, it would normally be carried out on a part of a program rather than the whole program

Unit testing: this refers to the testing of each individual subroutine or module in a suite of programs

Integration testing: this involves testing a complete suite of programs to ensure that they all function correctly when they are put together, for example being called from a menu

Tables will be designed to show how the computer reacts to entered test data i.e. normal, abnormal and extreme data.

Test for normal dataThis is testing for data that should be accepted by the system. The system must accept the data and continue running. Failure to do so means the system has an error.Form being Tested Field Tested Entered Values Expected outcomesLog In UserName 8 – 10 characters Accepts and logs in the userCustomerRegistration CustomerId 15 Characters Accepts and adds the customerRoomRegistration RoomNumber 3 characters Accepts and adds the room
