Hey this is a super basic structure question, but just went through all the material on this site instructing that the first step you should create an Issue Tree structure. Then I went through the case examples and see that this is not done often in the suggested answers? Am I missing something? Any help would be much appreciated.

Thanks!

Hi,

There are many ways to structure a case, not just an issue tree:

  • Mathematical (issue tree)
  • Workstreams (Buckets with bullet points)
  • Value chain / process / customer journey, etc
  • Segmentations
  • Frameworks
  • Project steps
  • Mix of them

You should be flexible in your approaches. Every time you build a certain structure you should take into account:

  • The objective of the case
  • Context
  • Type of the case

Best!

Hi,
unfortunately, most of the cases do not show an issue tree, probably because difficult to draw in a document. I recommend to approach every case with an issue tree and to show it to the interviewer. It is a powerful tool largely used by consultants in brainstorming sessions and much appreciated if correctly used during your interview.

Best,
Antonello

Agree!

This is a key part of 95% of the interviews. I encourage you to practice it always.

Here is sometimes substituted by "Diagram 1 - Case structure", but it´s not the same.

Hope it helps!

Cheers,

Clara

Hello,

In the case examples here on Preplounge the issue tree is always replaced by "Diagram 1 - Case structure". Anyway I agree with you that a proper framework is missing and I always suggest my candidates to write down a real Issue Tree structure. During real interviews a structure like the one proposed in the examples is not enough.

If you are struggling with frameworks and you want to discuss them, feel free to write me.

Best,
Luca
