How to do a "quality case" and review the case propoerly?

I've done many cases but I feel that my performance haven't improved continuously, and I am facing a “bottleneck”. I know that it is important to review cases properly and purposely improve weakness spots, but I don't have enough understanding of how to do these steps.

Could you provide some advice on how to review a case properly, in order to achieve stable improvement? Thanks!

Some people provide that advice, but it can actually be a quite naive approach. You will only become more effective in the method you are already using… which may not be the best method… in other words, you may not get better.

One thing is to go through the cases and identify where you are doing mistakes / facing trouble - and then prepare working sessions focusing on that specific issue (or figuring out how to improve it). Another one is to use those cases to improve without knowing how to improve.

Sometimes I suggest my candidates/coachees to review cases… but only after I explained them a different way of doing things, a different method, or made them experience a mentality shift. In that specific situation, they know what to look for and how to improve, so using cases they already know is a very efficient way to get concentrated practice on a specific topic (i.e., faster that on new cases). Very different from looking into old cases and randomly hoping to improve.

I am afraid I am not giving you the answer you may be looking for, but you are asking the wrong question. To know how to “review” a case, you'd have to know how to perform great in a case in the first place. 

So the real question is: how do you improve what needs to be improved? After you know the answer, you can use old cases to practice.

Hi there,

That’s a bit tricky, since as Pedro said you can effectively review cases only if you know what you did wrong. This is normally quite clear in some areas (eg, math or graph insights), but very difficult in others without external feedback (eg communication, logic of the structure).

In short, the ideal approach would be:

  1. Write down cases for which you notice possible improvements
  2. Identify if there is a pattern between improvements
  3. Redo the parts of the cases where you did mistakes and verify if you are now fixing the mistake

The more you practice with experience peers/coaches that can help to identify 1, the more progress you can make with this.

Best,

Francesco

Hi there,

This is truly tough as humans are notoriously bad at self-assessment. Furthermore, casing with others is a bit of a blind leading the blind scenario.

I'd honestly recommend coaching if you're facing a plateau/wal//bottleneck.

That said, if you really want to go it alone, find other candidates who are really good. Observe what they do, then reflect on your performance through that lens.
