in order to correctly work on the consultant thinking approach in a case, you should address structuring, communication and brainstorming. You can work separately on the three areas as follows:
#1 Structuring: Optimize your frameworks
In order to optimize your framework, you should personalize it proceeding as follows:
- Create some basic structures for your frameworks. Case in point should work well for that, although it presents too many frameworks, many of which not very useful. Still, it’s a good starting point.
- Start practicing cases (ideally, you should get to 50+) in person, online, or reading MBA handbooks. Every time you find a new approach to solve the case that is not present in your structure, write it down and add it to your framework keeping a MECE approach.
- Eliminate or consolidate the sections in your frameworks that you do not find useful to solve cases.
- Find commonalities between frameworks, so that you do not have to remember 7-8 structures completely different, but just few differences between frameworks.
- Once received the initial information from the interviewer, present the framework adapting it to the specific goals of the client, mentioning why you would like to explore a particular area and the connection of that area with the goals previously communicated by the interviewer.

#2 Communication: Present correctly your approach
If you do not communicate correctly your approach, even if it is perfect you will not score high for the interviewer.
The easiest thing you may do to communicate correctly a framework is to proceed as follows:
- Repeat the objective (“So you asked me to identify [OBJECTIVE], right?”)
- Present level 1 of the structure, numbering the main elements (“I believe we may do 3 things: Number 1 we may work on [FIRST TOPIC], Number 2 on [SECOND TOPIC], Number 3 on [THIRD TOPIC]”)
- Present level 2 of the structure, still keeping a structure based on numbers (“Let me go deeper in the first area. Here I believe we may follow 5 different steps. Step 1, I would like to [DETAILED DESCRIPTION OF THE FIRST STEP], Step 2…etc.”
Moreover, when presenting your approach, you should be able to be data-driven and to prioritize the critical areas based on that (so called 80-20 or Pareto approach).

#3 Brainstorming: Develop creative thinking whenever you are unable to find a proper framework
This is something you can do in case you are unable to find the right structure for a particular question. In order to brainstorm in a structure way, you can proceed in a way similar to what shown in #2, but taking more time in 1) Repeat the Objective and applying brainstorming in 3) Present your full structure. More specifically:
- Recap all the information you received until that moment. This will give you time without sounding you don’t know where to go.
- Identify 2-3 key elements that would constitute the fundamental areas of your structure (eg external vs internal, long term vs short term, etc.)
- After having defined the key areas, then start brainstorming for each of them.
