Precision, Tension, and Discipline: Writing Short Cases That Deliver

“I didn’t have time to write you a short letter, so I wrote you a long one.” – Mark Twain

Writing a short case study (defined here as fewer than three pages, excluding exhibits) is not simply a shorter version of long-form case writing; it’s a fundamentally different approach. As an author and writer, it requires sharp thinking, tight storytelling, and a relentless focus on the decision point, all of which can make the writing process significantly more challenging.

In long-form cases, writers have the luxury of including a full history and backgrounder, multiple sub-plots, and deep context that immerses the student in the story. With short cases, the immersion and impact comes from brevity and concision, where every word, every line, moves the student closer to the moment of decision. 

“I find writing effectively is often harder when short is the objective. Writers often fall in love with neat introductions, but every word deployed in setting the scene for a case study means you have one word less at your disposal to deliver the facts,” says Tom Watson, Editor of the Ivey Business Journal. “Short and sweet is the way forward and it can be powerful.”

Keeping a logical balance

Short cases are increasingly relevant because today’s students can easily research industry data online themselves, and there is a growing need to accommodate shorter attention spans and increased cognitive load.

“Good cases have a balance between background information and a rich discussion of the problems facing the protagonist with supporting data. Today, students can (and should) investigate relevant industry data on the Internet, or rely on their personal background and experiences,” says Fraser Johnson, Professor, Operations Management at the Ivey Business School. “Shorter cases focus on the key decision areas, so students focus on the management issues rather than the economics of the industry and business.”

But short does not mean easy. It is the job of the writer to design a curated decision environment where multiple answers can be defended, and no choice feels painless. In fact, difficulty and complexity are not linked to the length of the case; rather, the rigour comes from what the student must do, like interpreting incomplete information, managing constraints, and anticipating stakeholder responses.

Short cases are exceptionally effective for quantitatively heavy courses like Finance, Accounting, and Analytics, where the focus is on doing the analysis rather than synthesizing background facts. For strategy and marketing courses, writers should be aware that these subjects may still require slightly more context to be effective, but less is always more when this approach is paired with other experiential activities.

Best practices for writing

Instead of acting as an information repository, a short case should be written to serve as an extended prompt for deep analysis. And this is why short cases are no less rigourous than long cases. In fact, designing a case study that acts as a “short read, long think” has a much greater chance of impact and success than a “long read, no think” case.

“Typically, in longer cases, there are many passages that provide useless context that won't be used in any solutions. Avoid that in shorter cases,” says Rami Abu Rafea, Ivey HBA2/JD law student. “The benefit of short cases is the depth of analysis we're able to achieve.”

At its core, case study writing is all about structuring information with purpose. A common recommendation is for writers to work backward from the learning objectives or skills the case is designed to teach, and only include the information that is truly necessary.

Using the Case Difficulty Cube as your spine, it’s most effective to first plot out the analytical, conceptual, and presentation dimensions on a scale of one to three so that you are clear about the skills you want the case to elicit from your students.

After you’ve done your research, whether it’s a publicly-sourced case or a field-based case, write the decision in one clear sentence that answers the following questions: Who is the protagonist? What exactly must they decide? When do they have to make the decision? What constraints are they under? Why is this difficult?

Despite their brevity, short cases must maintain a clear narrative arc with a strong hook at the beginning and a coherent through-line to the end. A successful short case is not just a list of numbers; it requires a tight story with clear tension and stakes to remain engaging.

To save word count, writers should also focus on industry dynamics and emerging trends rather than creating historical “tomes”. Quotes should be used sparingly and only when they add specific information; there’s no need to include a quote to confirm an interview was conducted for a field-based case. While the document is short, the exhibits should contain the bulk of the analytical data, allowing the text to act as the narrative guide.

It can also be useful include to cliffhanger elements and real-world consequences to keep the scenario tense and the students invested. And detailing the aftermath with a clear ending provides a sense of closure and curiosity that can enhance the learning experience.

The bottom line: although designing short cases poses a greater challenge for the writer, the outcome for the student is more practical engagement and rigourous learning.
