Writing cases and case teaching notes

Introduction
A case is a story, so it has to be interesting, like a story, with a narrative, told and holding to whatever genre is chosen (confessional, detective, fiction, non-fiction).
Cases are also stories, backed up with evidence.
Like any story it needs strong characters, characters written with personalities.
Although unlike stories cases depend on data, on evidence offered in different ways.
Evidence may be peppered or buried within the case narrative, or it may be provided in appendices.
Furthermore, cases are driven by or offer challenges.
Cases generally problematise something or construct a nexus, a point in time, in tension, a point at which key decisions.
However a case may also present an on-going situation rather than a crisis.
