A Use Case is typically used in software development, although it may be used for any form of management. A USE Case specifies what must occur during a specific activity in order for it to be done properly. It is critical to use a USE Case because it clearly describes everything that is required for a process to succeed, as well as all of the individuals involved.
Use Case
Formats
There is no one format for use cases; instead,
depending on the nature of your requirements, you can use a variety of distinct
types and forms. The most crucial thing is to make sure the use case is simple
to comprehend.
You can use any of the many formats, or even develop your own,
as long as your use case has all of the essential information. You'll discover
a variety of use case templates with various designs. Some may take the shape
of a table, while others will be more detailed and text-heavy.

It's essential to follow a consistent format
when writing all of your company's use cases. People will grow accustomed to
writing in that format after you've created one. If you switch formats between
use cases, it will appear chaotic and make it more difficult for readers to
grasp. Consistent formats also make it easier for the reader to link diverse
use cases from complicated procedures with hundreds of them.
Common
Sections of a Use Case
Although you may build a unique sort of Use Case
for your company, there are several phrases that appear in virtually all Use
Case templates. Anyone who understands what a Use Case is will be able to grasp
the entire context of an activity with ease if all of these parts are included
in the Use Case.
Ø Use Case Name
Ø Summary
Ø Actors
Ø Preconditions
Ø Flow
Ø Level
Ø Trigger
Ø Stakeholders
Actors
The
individuals or items participating in the process are referred to as actors in
the use case. Let's look at an example of a use case to see how all of the
pieces fit together. Assume someone submits a support request for electronic
items on a website. The following actors are present in such a situation:
Primary
Actor
A secondary
actor is a person or group of individuals who are required to effectively
finish the process. If someone submits a support request through the website, a
customer service professional will need to assist them. This implies that
another person will be required to participate, and the procedure will need to
inform them. When a client submits a support ticket, it is often delivered
straight to the individuals who are responsible for assisting customers. In our
scenario, distribution to the secondary actor is a crucial component of the
case; otherwise, the client would never obtain the assistance they require.
Trigger
A trigger
merely specifies the action that leads to the Use Case. This part may be found
in most use case templates. The consumer clicking the button on the website to
generate a support ticket is the trigger in our case. The use case inside the
support system begins with that click.
Preconditions
The
preconditions are the requirements that must be accomplished in order for the
use case to be realized. If these requirements are not satisfied, the lawsuit
will be dismissed. In our case, the prerequisites are as follows:
The individual who initiates the request must have access to the internet.
The consumer must be able to view the website.
An active internet connection is required for the assistance agent.
It is
important to define preconditions. When preconditions are inadequately
specified, the intended action may not operate at all or result in serious
mistakes.
Flow
You must
specify the process flow that begins when a use case is launched. The flow must
specify how the communication will go, who will be shown the information, what
they must do, and where the principal actor will finish up.
When composing
the flow, there are three things to keep in mind.
Alternates
Are there any
other options for carrying out the action? In our use case example, the client
may want to be reached via the phone as an alternative route. Alternatively,
they may request that someone visit to their house to assist them with the
product. All potential alternative pathways to the use case must be listed
here.
Exceptions
This
determines what happens in the event of a flow failure. Exceptions can occur in
a variety of ways in our example:
During the
conversation, the customer's internet connection is lost. After then, they are
presented with an error notice.
The customer
service professional shuts the chat window by unintentionally, putting a stop
to the assistance session. Another representative will be with the customer
shortly, according to the consumer.
It's just as
vital to specify exceptions as it is to describe fundamental flow. Any good
system must have failsafe in place in the event of a failure. You will be
able to simply describe what has to be done in such a scenario if you are aware
of all the exceptions.
Level
It's essential
to assign a degree to the use case in order to convey the urgency with which it
must be addressed. The degree is determined by the sort of firm; for example,
most consumer complaints will be classed as high level, whilst general comments
will be labelled as low level. You must guarantee that whomever reads the use
case understands its significance in order for them to devote the appropriate
amount of time to it.
Stakeholders
Who are the
individuals who will be impacted by the use case? This portion of a use case
template is critical, as any project manager will tell you. There's no way to
develop a decent process if you don't know who will be affected, because you
won't be able to guarantee that your design accomplishes what it needs to do
until you know who will be affected. There are numerous stakeholders in this
scenario:
Ø
The
Customer Support Department - The goal of the entire department is to guarantee
that customers are satisfied.
Ø
The
Sales Department — if a customer is unable to resolve their issue, they may
return the merchandise, resulting in a loss for the sales department.
