2SYSTEM ANALYSIS AND DESIGN
Introduction:
The information system can be considered as the set of several pieces of software
application that are involved in information dissemination. A typical information system is a
collection of software, hardware, computer network, human resources and more. An information
system can be of many types like management information system, transaction processing
system, knowledge management system, office automation system and many more (Laudon and
Laudon 2016). The management information system is the most powerful and most popular
among all the information systems. The management information system is a computerized data
storage system that consist of financial data of an organization and process those data to generate
information and knowledge (Schomburg et al. 2017). The data models are used in the system
design for representing the data requirements. The entity relationship model does the same along
with describing the nature of the data. Domain model class diagram describes the static structure
of the object oriented system. In order to complete the ERD and class diagram, gathering the
requirements of the system is essential (Al-Masree 2015). The fact finding methods allows the
system analysts to gather the system requirement related data.
The report is based on the case study of You Can Fit In. The organization is currently
using OnAllAccounts accounting package. This package is not able to cope with the expansion
of You Can Fit In. The fact finding techniques other than the interviews has been described. The
data models have been presented through ERD and domain model class diagram. The sequence
diagrams have been created based on the information provided in the use cases.

Add Assignment 1:
Fact Finding Documents:
The requirement analysis is considered to be the process of identifying investigation,
documentation and evaluation of system requirements. The requirement analysis has a part
named fact finding technique that guides the actions of the system analysts while collecting
system requirement data (Alipour et al. 2016). The fact finding can be referred to the process of
collecting information and data based on the methods that include examples of present
documents, research, questionnaire, observation, prototyping, joint requirement planning and
interviews. The system analyst can use single or a set of appropriate fact finding methods for
developing and implementing the proposed information system (Bahill and Madni 2017). After
the essential facts are being collected, applying tools for converting the facts into information in
software development life cycle is important. It is because the tools cannot be utilized accurately
and efficiently if the system related information is not extracted from the collected facts. The
fact-finding methods are applied software development life cycle’s early stages like system
analysis, designing phases along with the late phase like post implementation (Ciochina,
Paleologu and Benesty 2016). The facts of the information system can be evaluated on the basis
of three individual processes like process-function for performing the system objectives, data-
facts for generating meaningful information and interface-design for interacting with the
potential end users of system.
The fact-finding methods are of various types. Each fact-finding method has its own
features, processes and conditions. There are total seven fact-finding methods that can be used
for gathering the system requirement information (Hu et al. 2015). These techniques are Joint

requirements planning, Questionnaires, Sampling of existing documentation, forms and
databases, Observation of the work environment, Prototyping, Interviews and Research and Site
visits. The detailed description of the fact finding methods have been provided in the following
section.
Sampling of existing documentation, forms and databases: The Sampling of existing
documentation, forms and databases allows the system analyst to evaluate the existing
OnAllAccounts accounting package for collecting facts from the present documentation other
than the human resources. Many types of documents can be used for collecting the facts from
present documents such as the e-mails, reports, suggestion box notes and customer complaints
(Dick, Hull and Jackson 2017). The reports can contain the reviews on the area of problem along
the issues in the organization performance. The collected manual forms can also be used for
collecting the facts. Computerized forms like Google forms or spreadsheet forms can be used too
as fact finding documents. After analyzing all the documents, the system analyst will create
several diagrams like flow charts, UML models, data models and more. Based on the generated
models, the program documentation and the user training manual is done. The sampling methods
are done by the system analysts for managing the above mentioned documentations (Ciochina,
Paleologu and Benesty 2016). The sampling method can be stated as the process of collaborating
the documents that represents the samples, records and forms. The sampling method entails that
two types of sampling methods exists such as stratification and randomization. The stratification
can be stated as the systematic procedure for deducting the modification of sampling data. On the
other hand, the randomization is the procedure of choosing the sample data indiscriminately. The
analyst can have better understanding of the proposed information system of You Can Fit In as

5SYSTEM ANALYSIS AND DESIGN
the evaluation of the present documents, files and forms are associated to the present information
system.
Research and Site Visits: The fact finding method that evaluates the issues that had been
already solved through other sources like documents or human is known as the research and site
visits. In order to provide a solution to the issue of requirements, the analyst will visit another
organization that had previously dealt with the similar issues. Moreover, the analyst may also
recognize the information from the reference books, database, internet and case studies
(Englehardt and Narayanan 2016). The main advantage of research and site visits is the time
required to solve an issue. As the analyst will follow the procedure that has been established, the
time required for providing the requirements of proposed solution is significantly less. The
researches always have the detailed information regarding the current development system. The
disadvantages of research and site visits are related to the restriction to access information as
those information is of another organization. If the previous solution is not documented
accurately and properly then this method cannot be implied.
Observation of the work environment: Another important fact-finding method is the
observation of the work environment. Observation of the work environment method states that
the system analyst take part in the business and studies the documentation flow. The system
analyst will apply the present system and extensively interact with the potential end user in this
fact-finding method. In case the user point of view is the main focus of the project then
observation can be considered as the most suitable fact-finding method (Nagorny et al. 2016).
The observation method can integrate the sampling method if needed. In this technique, the
sampling method is called work sampling. Through the utilization of the observation method, the

6SYSTEM ANALYSIS AND DESIGN
system analyst can easily identify how the employees and management of You Can Fit In work
on daily basis.
Questionnaire: Another useful fact finding method is the questionnaire. This method
allows the analyst to collect data from a vast amount of users simultaneously. Each user will
have a set of questions that can differ based on the purpose they will use the system. After they
fills the answers to those questions, the participants will send the form back to analyst. The
questionnaire method is extremely time saving technique because the system analyst will not
communicate with the participants individually thus the time needed to complete questionnaire
becomes less (Hong and Chen 2019). One thing that analyst must remember is that only the
system requirement related questions should be asked. If the questions are not related to the
requirements then the whole project would fail. Questionnaires can be of two types such as free-
format questionnaire and fixed-format questionnaire.
Use Cases:
The main functions are the registration of the members, collecting payments, creating
invoices, generating reports and monitoring attendance.
The roles that will be interacting with the system are members, accounting staff,
receptionist staff, management and admin staff.

Suitability: As per the comparison provided in the above section, the NetSuite ERP can
be the best solution for You Can Fit In. The organization wants a cost effective solution that can
deploy the system in cloud. As per the description of NetSuite it can perfectly fit to the
requirements of new information system.
Options for New Information System:
In-House System: The in-house system will be implemented in the premise of You Can
Fit In. The organization will purchase all the hardware and software resources required to
develop the system (Deitte et al. 2018). The team will be hired by the organization either
individually or a third party system development experts.
NetSuite ERP: This solution is more effective than the previous one. The NetSuite will
appoint a team of experts in You Can Fit In to collect data from them and generate a system for

15SYSTEM ANALYSIS AND DESIGN
the organization (Hamerman et al. 2015). This system will be hosted by the NetSuite
organization itself.
Cloud Based System: The organization can hire a team of experts for developing a
system. After the system is developed, they can contact any cloud hosting organization to deploy
their system (Tyagi, Agarwal and Maheshwari 2016). You Can Fit In will have a team to
maintain and monitor the system.
Conclusion:
From the above study it can be concluded that the proposed information system can
handle the business processes of You Can Fit In accurately and efficiently. The system will be
capable of collecting data from various input sources and store those data into a structured
database. The fact-finding methods discussed in the report consists of all the information that can
be used for collecting the system requirement data. Each of the fact-finding has been discussed in
detail so that proper knowledge of how the method works can be understood. Through the whole
assignment, a lot of system related data has been provided and analyzed. All those processes has
been done based on the fact-finding methods discussed in the report. The use case diagram
provided in the report consist of the information of how the user interacts with the system. These
interaction information is collected through the questionnaires and observation of work
environment. The report has effectively showed the connection between the use case and the
sequence diagram. As both the sequence and use case diagrams are dynamic models of UML,
both the diagrams has been properly used for capturing the behavioral requirements of the
system. However, the report does not show the process or conditions for validating the collected
requirements and created diagrams. The progress of each of the project management tasks has

16SYSTEM ANALYSIS AND DESIGN
been verified and the current progress report has been provided. It allowed to have a proper idea
of how the system project is progressing.
Recommendations:
Highly Skilled and Experienced Project Team: In order to implement a fresh
information system for the You Can Fit In, it is suggested that project team is created at the
beginning of the project. It is because, there exists no feasibility for identifying quantities of the
unavailable information. The team must be able to raise an alarm if complete data regarding the
project is unavailable. This will make Adam Apple recognize the feasibility of the present
project exception. The project team will be constructed with small number of experienced and
skilled members. Each of the project team member will have separate responsibility or in some
cases same. The project manager will be appointed to guide the team and project related tasks.
The project manager must work as the communication link between Adam Apple and project
team. The project manager will personally track the works of different team members so that
project related tasks can be controller appropriately. The team must have a system analyst and
may have one business analyst. The project team will have a member who is the internal staff of
You Can Fit In. The team will work in harmony to meet every project deliverable.
System Requirements and Measures: Like all the other organizations, You Can Fit In
has organizational goals along with the direction statements for performing the organization’s
business activities and processes. It can be seen that all the direction statements are not able to
satisfy the primary goals of You Can Fit In. The main requirement of the proposed information
system is to allow Adam Apple a solution that can handle all the processes of You Can Fit In.
The system must process the information of customers so that customer relationship management
processes can also be improved. The main focus of the requirement gathering methods (fact-

17SYSTEM ANALYSIS AND DESIGN
finding techniques) must be on recognizing how to collect, maintain and share information
among the authorized end users. The system and business analyst must generate a top-bottom
and wide perspective for the proposed information system. The project team must identify the
requirements of the customer. The analysts must create a set of conditions so that input collected
from questionnaire can be verified. The analyst must use fact-finding methods that can validate
the result of other method so that gaps of each technique can be minimized. Each requirement
should be documented properly so that project accuracy can be achieved.
Change Management: It is a very important to manage the changes that will happen in
You Can Fit In after the implementation of the information system. The project manager along
with Adam Apple will identify the advantages that the system will provide. These advantages
will be shared with the staff of You Can Fit In so that their support can be obtained. The system
analyst will generate a list of prototypes that can be tested by the staff. This way the staff will
have a proper idea of how the system will look like and changes done based on their feedback
will make the system more user friendly.
