Final answer:
Option B correctly describes a use case as a set of interactions between an actor and a system that results in an outcome of value. It involves sequences that depict scenarios where the system meets user goals, distinct from a problem statement, which outlines the issue being addressed.
Step-by-step explanation:
The term use case is best described by option B: "A description of a set of logically related possible interactions between an actor and a system that results in an outcome that provides value to the actor. Can encompass multiple scenarios." This captures the essence of a use case, which is used in software and system design to specify and articulate all the ways an end-user (referred to as an 'actor') interacts with a system to achieve a goal, including the user's motivations and the conditions under which the interactions occur. Each use case contains a description that provides a sequence of steps, detailing the interactions that occur.
A problem statement, on the other hand, is a concise description of an issue to be addressed or a condition to be improved upon. When designers start working on a new project, they use the problem statement to guide their work by identifying criteria and constraints that inform potential designs.
Principally, the process includes these steps:
- Identify a problem or a need.
- Define requirements and constraints.
- Generate ideas or brainstorm for possible solutions.
- Use requirements and constraints to evaluate possible solutions.
- Use the chosen solution to design and build a prototype.
- Test and evaluate the prototype and modify if necessary to finalize prototype.
- Communicate the results.
This problem-solving process underpins a significant part of any system or product design project, including the development of use cases.
