Not concise enough

Hi,

You should be structuring instead of talking:

• Immediately make a new structure if you know what the structure should be (e.g. if the problem is in sales and you know that for sales issue you should look at Sales Strategy / Coverage / Motivation / Skills & process
• Take a minute and come up with a new structure based on common sense 
• Ask the interviewer: "Could you pls tell me more about the process?"And build a structure based on the process.

Good Luck!

In ideal world, your answer has 3 bullet point and each of tham has another 3 sub-points.

Often its hard, but try to practice shifting the answer into the 3 simple points. 

If you are not certain about the answer (which is not so rare in cases) - answer with conditions. I.e. In case something is lower than XXX, the right approach is YYY. To confirm XXX, we would need to find out more about ZZZ...
