How to beat any casebook framework
Written by Dr. Sidi S. Koné on Jan. 9th 2023
One central point that candidates unfortunately nearly never understand: Case Interview Books JUST provide you with a basic toolbox in terms of which areas to look into for certain types of problems. However, they are very poor regarding HOW TO actually APPROACH a case and HOW TO DRAFT A ROADMAP for solving the case. 
Case interviews are a crucial part of the consulting recruitment process, and interview candidates at McKinsey, BCG, or Bain often turn to resources such as Victor Cheng's "Case Interview Secrets" or Marc P. Cosentino's "Case in Point" for guidance. 

While these sources can provide a useful first overview of the types of problems you might encounter in a case interview, they often fall short when it comes to the most important aspect: how to actually approach and solve the case.
In fact, the "framework learning philosophy" promoted by these casebooks is a major REASON why so many candidates fail to secure an offer from the top strategy consulting firms. 

A framework is only useful if it is tailored to the specific context of the problem at hand. This means that every element you consider – the "building blocks" of the framework – must be directly related to the question you are trying to answer.

The key is to start with the specific question you want to address, and then define the criteria that need to be met in order to answer it. 

In the vast majority of cases, value creation will be the central element – essentially, this means generating profit over a certain time period. 

From there, you can build a tree structure  to isolate the numerical drivers of your solution, and then map out the relevant "framework elements" to the sub-branches of the tree. 

This approach, visualized through a driver tree, is much clearer and more rigorous than any framework found in a casebook.

However, this approach requires time and qualified coaching to master. But it is ultimately the way that consultants think about problems – how can we optimize for value creation? By following this approach, you can give yourself the best chance of success in your case interviews and increase your chances of landing a consulting job.
