3. SOFTWARE REQUIREMENTS SPECIFICATION

3.1Primary objective The purpose of this document is to present a detailed description of the computerization

of the Glencore Company. It will explain the purpose and features of the system, the interfaces of

the system, what the system will do, the constraints under which it must operate and how the

system will react to external stimuli. This document is intended for both the stakeholders and the

developers of the system and will be proposed to the Regional Historical Society for its approval.

3.2. Introduction

This software system will be a database which will computerize all the manual operations

performed by Glencore Company.

Glencore is an aluminium workshop which deals in the manufacture and sales of various

kinds of doors, windows, room separations and other furniture (Mainly Cupboards) of aluminium

on clients commands and according to their specifications. This manufacturing is c arried out at

Kingsway Camp, Delhi-9 where the workshop is situated. None other than the Workshop,

Glencore is also comprised of a store where all the materials like aluminium materials, window

panes and minor materials are kept after being purchased from the manufacturers. Glencore hasaround 50 employees but the owner named Mr. Sheldon Cooper who is also the managing

director handles all the paper work and he has an assistant who helps control the flow of

materials from the store to the workshop, keeping track of the materials in stock and informs the

MD if some materials need to be reordered. At present all the paper works are carried out

manually by the MD and his assistant. As his business is expanding and the manual system has

become redundant and at times inefficient. In the manual system, all the data of the clients,

suppliers and the materials used are kept in books. The stock of the materials along with deals

with the supplier is also monitored manually.


7/125

How the manual system works?

The system consists of seven files:

Materials file: Stores details of the materials Client file: Stores details of the clients Supplier file: Stores details of the suppliers Work undertaken file: Keeps track of the work undertaken from clients Credit file: Keeps track of the amount of money clients owe

Quantity in stock file: Keeps track of the quantity of materials that are present in the

organisation

Transaction file: Keeps track of the purchases made

FACT FINDING

Interview (Transcript)

A meeting was arranged with the MD in order to investigate the system. On the 18th

February 2014 at around noon as the MD was free. A set of questions were prepared and

were asked to him, some questions were removed on the spot from the list, while others were

added.

Below is the transcript of the interview, comprising of the questions asked and the answers

given by the MD.

1). Me: Explain how your actual manual system works?

MD: The manual system normally keeps track of all the transactions with the clients, the suppliers


8/125

and the materials currently in stock. There are 4 main files used in the manual system namely

the client file, material file, work undertaken file and the credit file. For the payment of the

clients there is a receipt book and whenever there is a transaction with the suppliers, the

receipt obtained by the latter are kept.

2). Me: Can you explain to me which kind of data does each file stores?

MD: The client file usually stores all the details of the clients i.e. their name, address, contact

number etc The materials file contains all the details of the materials their price their

quantity in stock and their reorder level. The work undertaken file contains the name of the

client for who is the work, the descriptions of the products to be manufactured, the materials

needed and the total cost of the job. The dimensions of the products are usually kept in the

personal dairy of the MD. The credit file usually contains consist of different pages each page

is for a specific client. All the payments of the clients are registered in and their overdue is

calculated.

3). Me: What do you do when a client approaches you to do a work for him?

MD: First of all I go at the place where the door, window or furniture is to be placed and take

appropriate measurements. Then I generate a quotation for the client which shows how much

it will cost to do the work according to his specifications. The cost for the materials and

labour is considered to do so. If the client does not agree with the price another quotation is

made with the cheap materials and given again to the client. Once agreed the client need to

pay 50% advance and the rest after the work has been delivered. If the client agrees to give the job the quantity in stock for material file is updated. The qty in stock for the materials that

will be used are decremented by the qty of the materials that will be used for the job. Once the

materials file is updated the materials are taken from the store and kept in the workshop

4). Me: How do you prioritize your work?

MD: First of all I check which job needs to be returned immediately. But there are also some jobs

that can be done quickly are also given priority and if ever the client has already paid, his job

is done first. For this I have to check the work undertaken file and sort that file according to

their priority, this tasks takes time as each time it needs to be sorted and if its lost I have tocontact my clients once again and regenerate the work undertaken file.

5). Me: How do your clients do their payment and how do you deal with that?

MD: Usually most of my clients pay me an amount of money in advance and the rest after that the

job has been delivered. Whenever a payment is made, the overdue of the client is calculated

and he receives a receipt for each payment. The payment is also registered in the credit file


9/125

and the overdue is noted down.

6). Me: How do you deal with the suppliers to purchase the materials? Do you pay them once or it is

done on instalments?

MD: All the transactions with the suppliers are done in cash and therefore I do not have any

problem of outstanding balance with them. First of all materials have a reorder level,

whenever their number in stock is equal or less than the reorder level a list of such materials is

generated and the suppliers are contacted to see whether they have the required materials in

their stock. The process of generating the reorder list is very tedious as every day the

materials need to be counted and cross checked against their reorder level. Once the materials

purchased in the materials file their quantity in stock is updated.


10/125

Following The interview we made a summary of how the actual system finally works

1). The quotation generated by the MD

These quotations are usually generated before a work is started. It gives the client an idea of

how much it will cost and if he agrees with the price the work is started. This quotation is

usually difficult and time consuming to generate.

2). The receipt usually generated after the client has paid

This receipt is usually given to the clients whenever they make a payment or their work is

accomplished. Usually two copies of the receipts are generated, one is given to the client and the

other one is kept in the receipt book itself. It acts as a piece of evidence.

3).Details of client from the client file.

A Notebook is used to store details of the clients.

4).The quantity in stock file which keeps track of the number of materials in stock.

The quantity in order are recorded in another notebook. At the end of each day the number of

materials are counted manually and are tallied.

5).The material file which stores all the details of the materials.

This file is sorted according to the type of the material hence it facilitates the job of the MD

when he has to search details for a particular material. But the problem arises when the price of

a certain material needs to be altered.

6).The work undertaken file which stores all the details of work.

The records in the file are highlighted for works have already been completed. Those which are

not yet completed are not highlighted until completed.


11/125


12/125

When a client comes and orders for a work, details of the work and client is saved in the work

undertaken file. The total cost for the job is calculated and the overdue of the client is calculated

and the credit file is updated.

Whenever a client makes a payment the new overdue of the client is calculated and the credit fileis updated.

PROBLEMS WITH CURRENT SYSTEM

The current manual system has the following inefficiencies:

A. It is difficult to keep track of clients who owe the M.D money. Each and every time, the list

of such clients needs to be generated.

B. The contact numbers of the clients and the suppliers are often lost and difficult to retrace. If

ever the work undertaken file is misplaced all the clients need to be contacted and a new one

has to be created, not only the file but all the measurements and the quotations need to be

generated again.

C. It is always time consuming to generate the quotation, for the clients because each time the

material file needs to be consulted.

D. If ever a change is made in a file that is linked to others, then all the files need to be

consulted and the data needs to be changed in all the related files. This process is time

consuming.

E. It is often difficult to generate the lists of works that have not completed before their

deadline.


13/125

F. The material file needs to be altered each time, in order to change the prices of the materials

and the quantity in stock. This process is usually messy and sometimes new material files

need to be created.

G. It usually takes a lot of time to search for a particular data in a file. As the data in all almost

files are stored in chronological order the files need to be searched till the end or until the

required data item is found.

Solution Proposed

In order to solve all the above mentioned problems the manual system can be computerized. All

the files and the data will be stored in a database and data could be accessed in various ways

such as on forms, queries tables and reports. Further queries can be made to generate the reorder

list and other lists.

16/125

3.3.4 Non-Functional Requirements

Hardware requirements

CPU (INTEL CORE 2 DUO E6550)

Any processor available which will is efficient to store and process data will be good.

Therefore I strongly recommend an Intel core 2 duo computer system.

Reason: it is a good processor which is able to process data very quickly and works

extremely fast.

KEYBOARD (DELUXE WIRELESS KEYBOARD-LOGITECH)

It is a very important input device that will be used to enter data into the computer system. It

also allows creating commands and selection.

Reason: it is easy to use; the staff wont get too much problem in learning to use the

keyboard. It is also a very good way for communicating with the computer.

MOUSE (SCROLL OPTICAL WIRELESS MOUSE-LOGITECH)

An optical mouse is strongly recommended as it is very easy to use. It is used to make

selections by moving the cursor and clicking. It enables the user to use a graphical user

interface

Reason: it is easy to use; selection is made easier than on the keyboard and can easily be used

to edit texts.

PRINTER (HP Deskjet All-in-One series)

It will be used to print reports or letters to the peoples concerned. Therefore a laser printer is

recommended, it might be expensive but it give satisfying outputs.


17/125

Reason: it is fast and silent. It gives out good quality of printing and there is no major

expense on the maintenance of the printer.

LCD (View Sonic VX2235wm 22 Monitor)

Most of the work the librarian or the user will read on the monitor so as to make reading

easier a LCD of 22 inch is required. The LCD must be the one a view care one.

Reasons: it occupies less space; it will not affect the eyes of the user and facilitate the reading

as the screen is large enough.

UPS (uninterrupted power supply)

An UPS is very important as whenever there will be a power failure it enables the users to

complete their task and save it within a given time of about 45 minutes or more.

Reason: it prevents data loss when there is a power failure.

DVD RW (SONY-DRU-840A)

When data is processed it will be saved in RAM and the hard disk. It is necessary to create

backup files therefore a DVD RW can be used to store the backup files.

Reason: if ever there is a data loss it can be used to restore the system.

MOTHERBOARD (Biostar P4M900-M4 Intel 478 Micro ATX)

Reason: this motherboard is suitable for an Intel processor. It has on board sound andgraphics card.

CPU fan

Reason: It cools down the processor when it heats up.


18/125

Hard disk (256 GB)

It is storage device which usually stores all the programs and data in a computer system.

RAM (2 GB)

It usually stores all the current data being manipulated, current running program and partof the O.S.


19/125

2. Software requirements

Nowadays there are very powerful database management systems available. I have chosen

MS ACCESS 2013 to develop the software and WINDOS 8 PROFESSIONAL as the

3.4.4 Intended Benefitsa) The system automatically sorts all the data in all the reports after the slightest change.

Therefore the MD has no need to waste time and sort each file.

b) Search is made faster by the use of combo boxes and once more time is saving in the

process of searching data.

c) The use of validation techniques reduces virtually all the risk of having input errors.

d) The system enables the MD to keep track of all the clients who owe him money. He does

not need to generate a new list each time. It is done automatically.

e) The system also produces reports which indicates the MD all the jobs that need to be

done and those which are urgent. This shall reduce the risk of forgetting the completion

or installation of a job.

f) The reorder list is generated automatically by the system. Therefore the MD needs not to

check the Materials in stock file and generate the list each time.

g) There is less risk of data being lost for all the data will be stored on the database and in

case the software is to be corrupted, the advanced feature of MS Access 2007 creates a

backup automatically.

h) There is flexibility of data in the system, for the use of relationships between files shall

enable changes to be recognised throughout the whole system and allow easy updates.

i) The MD shall save on stationary fees as less paper shall be used for the computerised

system.

j) The system aids in calculating the total cost of a job. It also takes into consideration the

taxes and this task shall be faster compared to the old system as the MD will not have to

consult the materials file each time while calculating.


33/125

3.4.4 Limits of the scope of the solutiona) The system shall fail to operate when there is power failure as the computer requires

electricity to operate.

b) The MD may be computer literate but the other workers who will be allowed to use the

system during the absence of the MD are not computer literate. Therefore training shall

be required for them and this might slow the process of implementation. This might be

complicated and some worker may be reluctant to use the new computerised system.

c) If ever there are other new sorts of reports that will be required by the MD, the system

shall fail to produce such reports as such situations have not been catered or predicted.

d) The system does not produce any graphical or statistical representations of the data in the

system and this might have been a useful feature for the MD.

e)

However there are validations techniques there might still be input errors. (E.g.transcription or transposition errors while entering the name, surname or address...

entering an ID in the correct format but with the wrong code...)
