The purpose of a use case is to _______.​Question 13Select one:a.​Identify a sequence of steps to process a user functionb.​Identify a business event that requires system actionc.​Identify a useful objective for the new systemd.​Identify a user and describe one user  procedure

To answer the question step by step:

1. Understand the concept of a use case: A use case is a description of how a user will interact with a system to achieve a specific goal. It outlines the steps or actions taken by the user and the system to accomplish a particular task.

2. Analyze the given options:

   • Option a: "Identify a sequence of steps to process a user function" - This option suggests that a use case outlines the steps involved in processing a function that a user wants to perform.
   • Option b: "Identify a business event that requires system action" - This option implies that a use case identifies events in the business process that necessitate some action by the system.
   • Option c: "Identify a useful objective for the new system" - This option indicates that a use case helps in identifying objectives or goals that the new system should achieve.
   • Option d: "Identify a user and describe one user procedure" - This option suggests that a use case identifies a user and describes a specific procedure that the user follows.

3. Determine the most accurate option:

   • A use case typically involves identifying a sequence of steps that a user follows to complete a specific function or task within the system. It is more focused on the interaction between the user and the system rather than just identifying business events or objectives.

4. Select the correct answer: Based on the analysis, the most accurate option is:

   • a. Identify a sequence of steps to process a user function

Therefore, the purpose of a use case is to identify a sequence of steps to process a user function.
