SYSTEM ANALYSIS AND DESIGN 4
Introduction
System analysis is a very important process for any business wishing to develop,
purchase, or deploy a new information system (Alter and Browne, 2015). Additionally, constant
advances in technology also offer new opportunities to businesses to adopt the latest
knowledge in the business operations. Businesses need to employ system analysis and design
techniques in order to expand opportunities, improve efficiency, solve internal problems, and
it has a direct effect on the fundamental operations of the business (Glover, Sarma and Overbye,
2012). As such, system analysis and design help in evaluation business processes and the
requirements in order to come up with a customized solution that will allow the business to
compete effectively in the market.
Additionally, the business will be able to identify the key processes and operations
that can be automated and improved. This report is will attempt analyse Lilydale Movies
business requirements for a new information system. This is because of the growing business
and the need to optimize their operations. The report will cover the following aspects:
business background, key business processes, key business processes, identify functional and
non-functional requirements, data dictionary, and process description. All these aspects are
critical towards analysis and design of the new information system. The report will make use
of secondary sources including published journals, books, and relevant online materials.
Organization Background
Lilydale Movies is a rental chain and movie sale company that has experienced
exponential growth in the recent years and is wishing to upgrade their information system to
meet the new requirements. Alice Wong, Mark Goh, and Peter young opened the business
several years ago. Their combination has led to successful business because of their
knowledge in movies and interest in business opportunities. The company has been offering
extra services to the customers such as personal assistance, pickup, and delivery and this has
had a great positive impact to the business. The business has experienced enormous growth
than what the owners expected. The company has opened more stores across Melbourne and
is expecting to expand their services to other states and cities. The store managers have
received sufficient support from the owner by regularly keeping in touch with them.
However, because of the growth that the company is experiencing, there is need to have an

SYSTEM ANALYSIS AND DESIGN 5
information system that will provide support and monitor the performance of the business
without the owners having to physically visit the physical stores.
Business Problem
The key business problem currently being experienced by Lilydale Movies is business
automation, monitoring, and performance improvement. It is essential to address this problem
as it will enable the business owners to improve performance while being able to monitor
performance of the different stores from a single dashboard (Ramakrishnan, 2012). Also, the
owners will cut the costs of having to constantly communicate and travel to the different
stores regularly because automation will allow the business owners to generate reports and
financial statements from the system (Satzinger, 2012). Currently, every store uses its own
standalone software to manage selling and renting movies but they are not linked with other
stores. As such, the owners or the manager need to get different reports from the various
stores and compile them to create one business report. This is a very difficult task and is time
consuming (Wang and Hai, 2012).
Currently, each store has different movie titles and does not have a record of the
available movies in other stores and customers rely on the expertise of the employees and the
manager to offer advice on the movies available and how to get them. As a result, the
company has hire HISCO to analyse their business requirements and propose a suitable
information system that will be able to meet them. Some of the expected functions include:
security where the system should allow individual stores to modify and manage its own data
but allowing them read only access of information from other stores on the movies available
but sensitive data like customer data cannot be accessed or visible to other stores.
Additionally, the company wants to redesign its website to ensure that it allows the
customers not only to search but also rent or buy movies online without having to download
purchase order form. The website should support reservation of movies, ordering, renewals,
and online payments. The system should also enable the managers and business owners to
generate reports both for individual stores and a consolidated report from all the stores
(Satzinger, Jackson and Burd, 2013).
Some of the key functional and non-functional requirements. The current system
requires that a customer to register with Lilydale Movies by providing their personal details
such as email addresses, contact numbers, names, passport, Medicare, or driver’s license

number. Secondly, the system allows processing movie loans, generating overdue loans,
return loans, DVD/video maintenance, renewals, movie sales, and reservation.
System analysis is a very important to any business. For Lilydale Movie Store, system
analysis and design will enable the business to reduce cost and achieve flexibility and
efficiency (Satzinger, Jackson and Burd, 2012). If the correct path is taken and properly done,
the business will minimize errors while developing the new Movie rental information system
for Lilydale. Additionally, the company will save money and also ensures that appropriate
path is taken while developing the system (Tilley and Parveen, 2013). Additionally, good
system analysis and design techniques will facilitate better controls and management by
facilitating development of information system that will best suit the needs of the business
that will be wholly controllable (Fotache, Olaru and Iacoban, 2015).

Process Description
Top Level Process: Renting a Movie
This process involves a customer who visits the movie store either via the website
of physically going to the movie store. The customer enquires if the movie he/she is
interested is available. If the request is made online, the system queries the database and
returns the results. If the customer visits the store in person, the movie store attendant

searches for the movie on the system and confirms if it is available. If available, the
customer is given the invoice based in the amount of time he/she will rent the movie. The
customer makes the payment through credit cash or cash.

Techniques for Identifying Use Cases
Three techniques were employed in this project to identify the various system use cases. They
include user goal technique, CRUD technique, and event decomposition technique. In user
goal technique, the users were engaged and allowed to discuss the goals and what they
expected from the system. All the primary stakeholders with the likelihood of interacting with
the system were listed, determine the various system activities that will enable them get their
daily work done. This was achieved by asking the users how they would prefer to interact
with the system and analysing the existing system to come up with a number of use cases. In
this case, the use cases were a combination of newly requested function and existing system
functions.
CRUD technique is another approach that was employed in identifying the different use
cases. CRUD refers to Create, Read, Update, and Delete. In this approach, the system analyst
determined the various data elements that are supposed to be processes by the system and
come up with use cases that creates, reads, updates, and deletes the data elements. In this
case, data that is to be handle by the system was identified such as inventory item, customer,
rental/order, and shipment. Every data element was examined and use cases related to CRUD
were stated.
Event Decomposition technique is an approach that emphasizes on determining the different
events that a system should respond to and identifying the manner in which the system must
respond. In this technique, the system analyst first identified the events that they system

should respond to and events that trigger the system. This approach is better represented in an
Event Table.

Conclusion

SYSTEM ANALYSIS AND DESIGN 14
In conclusion, it is evident that Lilydale needs to implement a new information system
that will enable the business to meet the increasing business requirements. The company is
growing but the system that the company is using is not integrated and has a lot of challenges.
One way that the company will ensure that proper system is developed is by carrying out
system analysis and design to critically analyse the key business processes and how to better
integrate them. Currently, every store uses its own standalone software to manage selling and
renting movies but they are not linked with other stores. As such, the owners or the manager
need to get different reports from the various stores and compile them to create one business
report. Therefore, there is need to have an information system that will provide support and
monitor the performance of the business without the owners having to physically visit the
physical stores. As such, system analysis and design help in evaluation business processes
and the requirements in order to come up with a customized solution that will allow the
business to compete effectively in the market.
