It really depends on the case situation. For example:

1. If the case involve an large upfront investment probably better to use Capex vs Opex split
2. If the case is about identifying cost saving opportunities from operations probably better to use value chain breakdown
3. Etc

I would also suggest to confirm to the interviewer once you propose a path to ensure that he/she understand your reasoning

The key things is to understand what is the case question, what analysis you need to do to answer the question and what data do you need.

Hi,

Just remember these key principles:

1) MECE

2) Appropriate to the contexct

3) Fits your style/way of thinking and approaching problems

Hey there,

Agree with others that it deosn't really matter how you name the buckets of costs, as long as you have the right key cost components covered, which could be quite industry specific. If you have the right components, in some cases you don't even need to put them into 2 buckets.

Best,

Emily

Hello there,

How to divide the cost should depends on the nature of the industry and the case in question.
Other ways includes categorizing it based on the value chain.

Never opt for a specific categoriztion method just becuase it is easier.
Focus on crafting your own logic and utilize categorization which would help the client in addressing the issue the most.

Hope it helps.

Kind regards,
Nathan

Hi Anonymous,

The question should be less what is easier or not, but what is more appropriate in terms of structuring the case.

Whenever you are in a high fixed-cost / varialbe-cost business it might make sense to structure along those buckets, especially when you want to understand impact of top-line change (revenue) on bottom-line (profits).

Hope that helps - if so, please give it a thumbs-up with the upvote button!

Hello!

It´s not a good approach to have a pre-defined framework for splitting the costs, let it be fixed vs. variable or direct vs. indirect.

The important thing is to be able to think on your feet and decide which is the best structure per each case (this depends on the industry, the goals... in a nutshell, needs to be shapped according to the prompt).

Hope it helps!

Cheers,

Clara

Hi Anonymous,

direct or indirect could also be fine although a bit unusual. So far that your structure is MECE and you can identify all the relevant costs, it doesn’t really matter if you use fix vs variable or direct vs indirect (or even analyse the value chain). The important thing is that you keep a first level of the structure, and then start to brainstorm for each bucket after laying down your approach instead of brainstorming immediately different costs.

Hope this helps,
Francesco
