Hi,
Yes, unless you have 50+ cases done with good partners I would recommend always taking a minute to prepare your conclusion. And even with 50+ cases it's not the bad idea to take some time.
While taking the minute, spend this time on:
- Checking what was the initial objective (you won't believe how many candidates are answering the wrong question
- Collecting the numbers throughout the case to support the recommendation
- Preparing the recommendation
The typical structure is the following:
- What was the objective
- Your recommendation
- Arguments why the recommendation is valid (2-4 arguments) with the supporting numbers
- Additional things you would like to explore. In the order of priority:
- Things you still need to explore / data you need to get in order to provide a valid recommendation (Very typical for McKinsey cases where the interviewer guides you and interrupts in the middle of the case to provide a conclusion
- Things you've slightly covered during the case but have not come to a particular measurable solution or were not the part of the original objective (e.g. alternative growth options or some questions on creativity)
- Risks
- Next steps
