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.

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

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
