A case study is an in-depth, detailed examination of a particular case (or cases) within a real-world context. [1] [2] For example, case studies in medicine may focus on an individual patient or ailment; case studies in business might cover a particular firm's strategy or a broader market; similarly, case studies in politics can range from a narrow happening over time like the operations of a ...
Below is a sample use case written with a slightly modified version of the Cockburn-style template. Note that there are no buttons, controls, forms, or any other UI elements and operations in the basic use case description, where only user goals, subgoals, or intentions are expressed in every step of the basic flow or extensions.
Use case analysis is a technique used to identify the requirements of a system (normally associated with software/process design) and the information used to both define processes used and classes (which are a collection of actors and processes) which will be used both in the use case diagram and the overall use case in the development or redesign of a software system or program.
A decision-forcing case is also a kind of case study. That is, it is an examination of an incident that took place at some time in the past. However, in contrast to a retrospective case study, which provides a complete description of the events in question, a decision-forcing case is based upon an "interrupted narrative."
While a use case itself might drill into a lot of detail about every possibility, a use-case diagram can help provide a higher-level view of the system. It has been said before that "Use case diagrams are the blueprints for your system". [2] [3] Due to their simplistic nature, use case diagrams can be a good communication tool for stakeholders.
In the IRAC method of legal analysis, the "issue" is simply a legal question that must be answered. An issue arises when the facts of a case present a legal ambiguity that must be resolved in a case, and legal researchers (whether paralegals, law students, lawyers, or judges) typically resolve the issue by consulting legal precedent (existing statutes, past cases, court rules, etc.).
Case citations are used to find a particular case, both when looking up a case in a printed reporter and when accessing it via the Internet or services such as LexisNexis or Westlaw. This format also allows different cases with the same parties to be easily differentiated. For example, looking for the U.S. Supreme Court case of Miller v.
An embedded case study is a case study containing more than one sub-unit of analysis (Yin, 2003). Similar to a case study, an embedded case study methodology provides a means of integrating quantitative and qualitative methods into a single research study (Scholz & Tietje, 2002; Yin 2003). However, the identification of sub-units allows for a ...
