First of all thank you very much MT for the work that hugely benefit managers, or rather employees, accross the world. 

I had this question about the podcast - effective decisions - part2.

Here we talked about one action and sticking to it. Do we have any guidelines on how long we normally stick to the chosen alternative before we change course?

In a rapidly changing world, it could be that on one extreme, we assess our situation every single day and change course or take new alternative. This would be very inefficient. On the other extreme we stick to one chosen alternative for the next 5 years before reassessing our situation.

thanks again.
