How much of your work is waiting for others to do something?
Work is global, interconnected, relational, shared. It’s true today and it will be even more true in the future.
Yet waiting never corresponds to adding value. So, if a good part of your work depends on others doing something, you have a huge problem that you need to address.
On the other hand, many use others as an excuse when they fail to deliver, when they are unsure on what to do, when they fear their work might be wrong, when they have something more important to take care of. This also needs to be addressed, but it’s easier (not simpler though).
