Trans Tech Gone Global: Expanding and Centralizing All Branches bring them to
be the leading IT companies in the Asia.
Trans Tech Gone Global is an IT company where the headquarters is located in Shah
Alam. Currently Trans Tech has 4 other branches all over Malaysia which operates
individually. This company plans to open their 5th branch in Singapore. In conjunction
with the opening of the 5th branch, Trans Tech has decided to centralise all branches
including the 5th branch in Singapore so that all operation can be monitored from the
headquarters. Due to the centralization of all branches to the headquarters and also the
recent expansion of the main office, Shah Alam branch will experience slow internet
connection since they are using a broadband connection with low bandwidth. This
problem is to be discussed and solved before the opening of the Singapore branch. The
Singapore branch will consist of 5 different departments namely Admin, Human
Resource, Finance, IT and Warehouse. Each department will be provided with 10
computers, 4 printers, a few peripheral devices and its respective equipment except for
warehouse with only 2 computers and other related peripherals and equipment.

Although this company has 4 operating branches, they also provide door-to-door
sales for big companies where their mobile salespersons are required to do sales all
over Malaysia. It is very important for these salespersons to have first-hand information
about the product knowledge and the stock level for each of the equipments. They
should be able to access the internal network of their respective branches and if needed,
access the network of headquarters as well. For this purpose, each sales person is
provided with a laptop for them to take along all destinations. This will prevent from any
sales hiccups since Trans Tech has become a reputable company in Malaysia.

With the opening of the 5th branch and centralizing all branches to the
headquarters, Trans Tech is prone to be seen as one of the leading IT companies in the
Asia.

Bagusmart Hypermarket: Adapting Technology for improving and upgrading their
business - A Simple Case Study
Bagusmart is a chained grocery shop that sells all groceries’ needs. Their motto is
‘providing every family’s needs in one roof’. The grocery shop started as a family
business since year 2000. Their first store was opened in Banting, Selangor. To-date
they have a total of 15 branches around Selangor. Since the opening of their first shop till
present, Bagusmart management does not have any Information System to handle their
inventories, stocks, payroll and financing. Everything was done either by using manual
records or by using a simple stand-alone system such a Store Keeper’s System. The
stand-alone system was developed by one of their ex-staff with minimal functions using a
simple DBMS application program.

As their business developed, the Managing Director of Bagusmart, Mr. Hadif
expressed his intention of having an automated Information System that can improve
and upgrade their business to be more efficient, systematic and reliable. He feels that it
is important for Bagusmart to have a proper system since they are expanding quite
rapidly over the years. Failing to do so may cause inefficient management that might
cause Bagusmart to fail its operation which will bring great loss to the company.

In order to materialize this plan, Mr. Wafiy, a System Analyst was hired and
given a task to handle this project. As the requirement stated, the Information System
will have to automate all the necessary functions and link all the branches in a single
system within a certain budget. This system must be able to be used in all branches and
monitored by the home branch. Therefore, Mr. Wafiy was given a month to do the
necessary and produce a convincing System Proposal so that Mr. Hadif can all the
needed action in developing an Information System for Bagusmart.

62

Developing Independent Learning in Vibrant Environment

Based on the article given, answer the following questions:

Question 1:
As a System Analyst, what will be the first thing that Mr. Wafiy should do in regards to the
project? Explain why the action is important and needed.

Suggested answer:
Requirement Gathering and Analysis: This phase is basically the brainstorming phase
and often consists of sub-stages like Feasibility Analysis to check how much of the idea
can be put into action.

Question 2:
Mr. Wafiy will not handle the project himself. Please explain who will be joining Mr. Wafiy
in this project by providing the roles of everyone you have mentioned.

Suggested answer:
The steering committee, vendors, programmers, network administrator, data analyst,
managers, users.

Question 3:
What is the best method to gather all the necessary information for this project? Why do
you think this method is the most suitable chosen by you?

Suggested answer:
#1: One-on-one interviews-There are many good ways to plan the interview, but
generally you want to ask open-ended questions to get the interviewee to start talking
and then ask probing questions to uncover requirements.

#2: Brainstorming - The appropriate subject matter experts get into a room and start
creatively brainstorming what the solution might look like. After all the ideas are
generated, the participants prioritize the ones they think are the best for this solution. The
resulting consensus of best ideas is used for the initial requirements.
Or Choose any suitable and logic answer given by students

63

Developing Independent Learning in Vibrant Environment

Question 4:
In your opinion, what is the approach that Mr. Wafiy should use in Detailed Analysis;
Process Modeling or Object Modeling? Explain your answer.

Suggested answer:
The detailed investigation of the system is carried out in accordance with the objectives
of the proposed system. This involves detailed study of various operations performed by
a system and their relationships within and outside the system. During this process, data
are collected on the available files, decision points and transactions handled by the
present system. Interviews, on-site observation and questionnaire are the tools used for
detailed system study. Using the following steps it becomes easy to draw the exact
boundary of the new system under consideration:

 Keeping in view the problems and new requirements
 Workout the pros and cons including new areas of the system
All the data and the findings must be documented in the form of detailed data flow
diagrams (DFDs), data dictionary, logical data structures and miniature specifications. It
includes planning for the new system, analysis of requirement, system constraints,
functions and proposed system architecture, prototype of the proposed system and its
analysis.

Question 5:
It is important that the Information system for Bagusmart is maintained properly and
periodically. Explain what will be the risks if the maintenance phase is not conducted for
this project.

Suggested answer:
Maintenance is necessary to eliminate errors in the system during its working life and to
tune the system to any variations in its working environments. It must meet the scope of
any future enhancement, future functionality and any other added functional features to
cope up with the latest future needs. There are always some errors found in the systems
that must be noted and corrected. Failing to do so will cause system to breakdown and
become inefficient and useless to the company. Also it will open opportunity for threats
and viruses that may jeopardize the company.

64

Developing Independent Learning in Vibrant Environment

Question 6:
Using this case study as an example, explain the importance of having a good
documentation for the whole project. What are the potential risks if there were no
documentation of poor documentation?
Documentation in this project used to communicate, instruct and record the information
for any reference or operational purpose. They are very useful for representing the formal
flow of the present system. With the help of documentation it is very easy to track the
flow of the system's progress and they working of the system can be explained very
easily.
It helps to provide the clear description of the work done so far. It is essential that the
documents prepared must be updated on regular basis this will help to trace the progress
of work easily. With appropriate and good documentation it is very easy to understand
the how aspects of the system will work for the company where the system is to installed.
It is also help to understand the type of data which will be inputted in the system and how
the output can be produced.
After the system is installed, and if in case the system is not working properly it will be
very easy for the administrator to understand the flow of data in the system with
documentation which will help him/ her to correct the flaws and get the system working in
no time.

‘All-You-Can-eat’ Buffet Restaurant; A new facelift. – A Case Study

Aleesha has just opened an ‘all-you-can-eat’ buffet restaurant in Jalan Telawi, Bangsar.
All-you-can-eat buffets are a brilliant concept where customers pay a fixed amount and
everything on the table is for them to sample. Aleesha’s buffet consists of a huge variety
of Japanese and local/Western dishes, from sashimi to sushi to tempura and fresh
seafood, and even Malaysian favourites such as wanton and satay. It's a perfect place
for gatherings, birthday parties, tour groups & company dinner. With its incredible design
and special lighting, it’s got just the right amount of style and comfort.

Since Aleesha’s restaurant is new, there are many problems that need to be solved
and one if it is the related to the cash register. Aleesha is facing a problem where there is
no proper record of the number of customers in her restaurant every day. She is finding it
difficult to keep track of the number of buffet sets she sells each day to her customers.
Since she keeps track of customers’ payment manually using a generic receipt book, she
is also worried if her staffs are not being trustworthy. Every day, her restaurant will be
crowded with many customers but her profit margin is lower than expected. For this
reason, she needs a proper system to help her keep track of the number of customers,
no of buffet, buffet type and also to track the payment through printing out the receipt to
be kept as record and to be given to customers.
Aleesya’s restaurant schedule:

Buffet Price per-Head Buffet Hour
Buffet Lunch RM78.00++ 11:30~16:20 [Weekday& PH]

Buffet Dinner RM88.00++ 17:00~21:30 [Weekday& PH]

Buffet Supper RM78.00++ 21:40~23:40 [Weekday& PH]

Aleesha is hoping that her restaurant will run smoothly without any hiccups and she is
willing to try all means to solve her problem. She was advice to consult a programmer to
solve her problem.
If your group is the team of programmer that Aleesha consulted, what would your answer
be for the following questions?

70

Developing Independent Learning in Vibrant Environment
Please answer the following question based on the article:
Question 1:
What is the best way to solve Aleesha’s problem?
Suggested answer:
to create a system that can

 Calculate the number of set buffets according to the buffet type ordered by
customers on every order.

 Calculate the total payment that customers should pay.
 Calculate the balance payment that the cashier needs to give in case of over

payment.
 Keep record of grand total of buffet sold and total collection for each day.
 Print receipt for customers and restaurant for record keeping purpose.
Question 2:
You are using C++ and ready to start with the coding, explain to other programmers how
you would declare the variables and its type for the system suggested above.

Trans Tech Gone Global: Expanding and Centralizing All Branches bring them to
be the leading IT companies in the Asia.

Trans Tech Gone Global is an IT company where the headquarters is located in Shah
Alam. Currently Trans Tech has 4 other branches all over Malaysia which operates
individually. This company plans to open their 5th branch in Singapore. In conjunction
with the opening of the 5th branch, Trans Tech has decided to centralise all branches
including the 5th branch in Singapore so that all operation can be monitored from the
headquarters. Due to the centralization of all branches to the headquarters and also the
recent expansion of the main office, Shah Alam branch will experience slow internet
connection since they are using a broadband connection with low bandwidth. This
problem is to be discussed and solved before the opening of the Singapore branch. The
Singapore branch will consist of 5 different departments namely Admin, Human
Resource, Finance, IT and Warehouse. Each department will be provided with 10
computers, 4 printers, a few peripheral devices and its respective equipment except for
warehouse with only 2 computers and other related peripherals and equipment.

Although this company has 4 operating branches, they also provide door-to-door
sales for big companies where their mobile salespersons are required to do sales all
over Malaysia. It is very important for these salespersons to have first-hand information
about the product knowledge and the stock level for each of the equipments. They
should be able to access the internal network of their respective branches and if needed,
access the network of headquarters as well. For this purpose, each sales person is
provided with a laptop for them to take along all destinations. This will prevent from any
sales hiccups since Trans Tech has become a reputable company in Malaysia.

With the opening of the 5th branch and centralizing all branches to the
headquarters, Trans Tech is prone to be seen as one of the leading IT companies in the
Asia.

Bagusmart Hypermarket: Adapting Technology for improving and upgrading their
business - A Simple Case Study
Bagusmart is a chained grocery shop that sells all groceries’ needs. Their motto is
‘providing every family’s needs in one roof’. The grocery shop started as a family
business since year 2000. Their first store was opened in Banting, Selangor. To-date
they have a total of 15 branches around Selangor. Since the opening of their first shop till
present, Bagusmart management does not have any Information System to handle their
inventories, stocks, payroll and financing. Everything was done either by using manual
records or by using a simple stand-alone system such a Store Keeper’s System. The
stand-alone system was developed by one of their ex-staff with minimal functions using a
simple DBMS application program.

As their business developed, the Managing Director of Bagusmart, Mr. Hadif
expressed his intention of having an automated Information System that can improve
and upgrade their business to be more efficient, systematic and reliable. He feels that it
is important for Bagusmart to have a proper system since they are expanding quite
rapidly over the years. Failing to do so may cause inefficient management that might
cause Bagusmart to fail its operation which will bring great loss to the company.

In order to materialize this plan, Mr. Wafiy, a System Analyst was hired and given
a task to handle this project. As the requirement stated, the Information System will have
to automate all the necessary functions and link all the branches in a single system
within a certain budget. This system must be able to be used in all branches and
monitored by the home branch. Therefore, Mr. Wafiy was given a month to do the
necessary and produce a convincing System Proposal so that Mr. Hadif can all the
needed action in developing an Information System for Bagusmart.
