2SYSTEM ANALYSIS AND DESIGN
Introduction:
The information system development can be referred to the organization approach of
implementing a new technology in organization environment. The entire development process is
guided by the set of rules defined in the respective software development lifecycle
(Abrahamsson et al. 2017). The system analysis and design is a very important part of the system
development. These two activities can be considered as the base of system implementation. The
system analysis the process of gathering business and user requirements of the system and
evaluating those requirements to generate system requirements (Alshamrani and Bahattab 2015).
In order to gather requirements, the system analyst have to communicate with the potential end
users and organization top management. There are various ways analyst can collect user and
business requirement related data from many sources. However, applying all the methods in a
system analysis task is not possible. That is why only a few methods are selected for collecting
requirements. The system analysis phase of the project ensures that all the users and functions of
the system is taken into account before design phase starts (Fernandez-Saez et al. 2015). The
system design, on the other hand, is for visualizing the software through various diagrams like
use case, domain model, sequence and many more. The UML diagram is the most popular
among the system designers because it can represent both the structured and behavioral element
of the system (Torre et al. 2018). The data models are very essential for capturing the data
requirements. The ERD is the most common data model among all.
The report is created based on the requirements of You Can Fit In. The report present a
detailed report on the used fact-finding techniques. The description of the fact finding techniques
along with its advantages and disadvantages are provided. Use case diagram is included for
showing the interaction of the users with the system. Domain model, on the other hand, shows

3SYSTEM ANALYSIS AND DESIGN
the static structured. The Sequence diagram shows the extreme dynamic nature of a specific use
case. The data model is represented in the report through the entity relationship model.
Add Assignment 1:
Fact Finding Documents:
In order to study the system, the analyst will gather adequate amount of information of
the user and business requirements. These information are called facts. The process of collecting
the facts must be guided by several rules (Ryglicki and Hodyss 2016). Many ways are available
for collecting the facts and each of those has different rules and processes. In this report, the
description of three fact-finding methods is given. These methods are chosen such way that gaps
of each method can be filled. These methods are well configured and able to collect the facts in a
very different ways. The selected fact-finding methods are questionnaire, prototyping and site
visits.
Questionnaire: The questionnaires are one of the most used fact-finding methods. The
questionnaire is used when the number of users are large. The questionnaire allows the
organizations to collect data from numerous participants simultaneously, thus reducing the
amount of time required. All the questions in the questionnaire must be related to the proposed
system. The questionnaire can be categorized as free and fixed format question (Ryglicki and
Hart 2015). The advantage of the questionnaire is collecting data from the participant freely. It is
an inexpensive process. The time required for executing this method is small. The biggest
disadvantage is that collected forms can have inaccurate information. The analyst does not have
any control over answers.

4SYSTEM ANALYSIS AND DESIGN
Prototyping: The prototyping can be referred to as most effective fact-finding technique
for collecting proposed system’s requirement facts. The prototypes can be referred to the pre-
design of the proposed system. These prototypes are clickable and provide an idea of how the
system will work (Medina et al. 2018). The advantage of the prototype is that users of the system
can have proper idea of the system before it is complete. The disadvantage is that users are not
able to understand features and reliability.
Site Visits: The site visit is capable of collecting the business requirements more
effectively than any other fact-finding technique. This process states that the analyst will access
the organization’s information directly. An assistant, who is an existing employee of You Can Fit
In, will be assigned to analyst to help understand the business data (Ryglicki and Hart 2015). The
advantage is collecting core business related requirement with utmost quality. The disadvantage
is that analyst can misunderstand the business data can create wrong system requirements.
Questionnaire Questions: The selected participant is the member.
i. How would you like to access the system?
ii. Would you like to have your own account?
iii. Would you like to feature your image in the account?
iv. Would you like to send queries from the website?
v. Would you like to make payment from the website?
Use Cases:
The sign up and sign in the most basic functions of the system. The service booking and
payment are the most important functions of the proposed system.

5SYSTEM ANALYSIS AND DESIGN
The staff, member and management are the main roles who will interact with the system
mostly.

(Source: Created by Author)
Membership: The membership is accessed by the staff and member. Staff can access the
membership of every member. However, the member can check only their membership. In order
to check the membership, the member have to login to the system first.
Sign In: The authentication policy is employed in the system through this Sign In
function. The member will sign in to the website/system to see their purchase details, invoices,
make payments or do other authorized things. To sign in to the system, the member will use the
login credentials provided to them during registration.

6SYSTEM ANALYSIS AND DESIGN
Pay: The members will access this use case. There will be a payment gateway through
which the payment will be done. The system will store the invoices. For each unpaid invoice, the
member can pay the cost through this system.
Change Member Details: After the member registers, they cannot change their details.
This implies a great way of securing data into the system. In order to change the details, they
have to contact staff of You Can Fit In. The staff will verify the reason for changing details. If
the reason is verified, the staff will update the details.

Suitability: The PIXEL8 is the information system vendor that provide organization wide
system solutions in a very low cost. The customer satisfaction is a huge factor in system
outsourcing. However, the system development is based on the conventional functions of e-
commerce system and internal operations (Web Solutions | Info Systems | Security Solutions |
Pixel8, 2019). The organization wants the system to be implemented in cloud environment and
PIXEL8 is expert in this domain. The organization provide a very good after sale service. The
cost of the project matches with the proposed cost. Therefore, the overall requirements of You
Can Fit In’s system matches with the services that PIXEL8 provides. Thus, PIXEL8’s software
package is most suitable for You Can Fit In.
Options for New Information System:
In-House System: The in-house states that every process or operations will be executed
within the organization without depending upon any third party organization. The team
responsible for maintaining the process will be hired by You Can Fit In. The system hardware
will be installed within the premise of the organization. The organization will take all the
responsibilities of system development project (Madurapperuma, Ebert and Kuruppuarachchi
2018). In case of in-house system, the upgrades are done by the organization itself. The in-house
system upgrades are very expensive. The system will not be flexible. The organization have to
use the maximum capability of the system no matter how much the pressure is. On the other

18SYSTEM ANALYSIS AND DESIGN
hand, the system will be extremely secure as it cannot be accessed from outside. The in-house
system does not provide remote access to data. In case the organization wants a system that can
be accessed from various locations, outside of organization premise, the cost will increase
significantly.
PIXEL8: The IS solution of PIXEL8 supports Enterprise Resource Planning Structure
along with the most simple user interface. The client organization needs multi-layer permission
and users. PIXEL8 also provides browser application platform. The system will be developed
and deployed by the PIXEL8 (Web Solutions | Info Systems | Security Solutions | Pixel8, 2019).
You Can Fit In will sign a Service Level Agreement with PIXEL8. In case You Can Fit In wants
to upgrade the system or scale it to adjust with the business need, PIXEL8 will be contacted and
new service level agreement will be signed.
Cloud Based System: The cloud based computer system is a part of cloud computing
application. This solution is created based on the shared servers instead of personal devices and
servers. The system will developed by the You Can Fit In and then deployed in a hosted cloud
environment. The host will allow the organization to purchase the service based on the time or
resource. In case of cloud, many organization share the same cloud environment, thus the
efficiency of collaboration increases hugely (Abbas et al. 2015). You Can Fit In can choose
software as a development as the cloud solution. The hired team will complete the project from
the beginning to the end. The Hostgator can be used for hosting the system online. This solution
will allow the organization to access the system remotely using string internet connection.

19SYSTEM ANALYSIS AND DESIGN
Feasibility Study:
The operational feasibility can be measured in terms of the service, proposed system
solution can provide You Can Fit In. It measures the satisfaction of the end users. It also counts
how many requirements, defined in the requirement evaluation phase, is satisfied by the system.
Through the proposed information system, You Can Fit In can provide many opportunities to the
members and staff.
Economic Feasibility: This feasibility study allows You Can Fit In to determine whether
the project can satisfy the investment. The cost of project is $67,600.00. The system can improve
the customer relationship and attract new potential customers. The social media marketing can
create new ways of revenue for the organization. The cost of project can be retrieved by the
system within one year. The system is a suitable solution in terms of economic feasibility.
Scheduling Feasibility: The scheduling feasibility directly determine the success of the
project. The project needs total 27 days to be completed. As the project is small and easy, which
will include only the conventional functions of a system, the system may not face any major
deadline issues. You Can Fit In can implement the system into environment within one month of
its project initiation and this makes the project suitable as per schedule.
Technical Feasibility: The system will be developed and deployed by the NetSuite
Corporation. For this reason, to build the system, You Can Fit In will not buy any hardware or
software resources.
Legal Feasibility: The proposed project does not violate any legal requirements such as
social media, data protection and zoning laws. The project will maintain the state and national

20SYSTEM ANALYSIS AND DESIGN
cyber laws for developing the system. During its lifetime, the system will process all the data and
execute its functions by following every possible laws.
Conclusion:
The above study concludes that the proposed system for You Can Fit In is capable of
managing the works of the organization. The processes will be more efficient and effective. The
system will collect data from various input nodes like staff computers, customer devices and
store those data into the database for later usage. The database is an integral part of the
information system which stores the data in structured, semi structured or unstructured database.
The fact-finding techniques has been discussed very accurately in the report. The selected fact-
finding methods fills the gaps of each other and provide a complete requirement gathering
approach. However, the system does not provide detailed information of who will conduct the
fact-finding techniques and how it will be completed. The data models and the UML diagrams
illustrates that fact-finding methods are capable of collecting all the data properly. The system
interaction requirements have been collected accurately and the developed use case is capable of
capturing all the system behavior related data. The use case is done considering the members and
the management. Along with them the staff of the organization is also considered to show how
the system will be used by the organization internally. The provided use case description is
complete and accurate. The system provides the details of the classes and relationship among
them using the domain model class diagram. The use case, domain model class and sequence
diagram perfectly captured the structural and dynamic nature of the proposed system.

21SYSTEM ANALYSIS AND DESIGN
Recommendations:
Service Level Agreement: The service level agreement or SLA agrees to the service
customer, You Can Fit In, will receive from the supplier, PIXEL8. The service level agreement
must include the details of the services to be provided by the supplier. You Can Fit In must
provide all the possible information of services. If PIXEL8 breaches the SLA because all the
information is not available, the supplier will not receive any penalty. The service level
agreement must include the conditions of service availability, specifics of the proposed services
and many more SLA elements. The client organization must ask the provider to make the SLA
statistics available in online so that You Can Fit In can check the agreements are met or not. The
metrics that must be included into the SLA are service availability, business results, security,
technique quality and defect rates. The defect rates defines the error percentage in terms of major
deliverables. Miss deadlines can also be inserted into the SLA. The SLA must include the fact
the service provider will update the security patches and install antivirus in the system.
Change Management: The implementation of a new information in You Can Fit In can
create employee issues. The existing customers will also face issues when the conventional
processes will change. The employees have to develop new skills and learn about new things.
For managing this issue, the organization can create a manual training process. This training will
allow the employees to learn about how they can perform their job on the system. During this
training period they can learn about how to cope with changed environment and job description.
The change management must be initiated at the top level of You Can Fit In. The owner of You
Can Fit In must appreciate the change, otherwise they cannot make employees believe in the
system. The project must include each type of employees in the organization so that everyone
can feel like they are part of the project.

22SYSTEM ANALYSIS AND DESIGN
Robust Solution Design: If the organization is small and implementing a very small scale
application then the install, configure and deploy can work. In order to make medium seized
information system that expands throughout the organization, the robust system solution is
essential. Most of the carelessly designed systems does not meet the business and user
requirements just because those systems are not robust.
