as the company scales, the probability of things breaking increases. it can range from a communication breakdown to pure sloppiness depending on the situation. but always remember that it’s never ever the individual’s fault.
there are only two possibilities:
a. you hired the wrong person in which case you’ve to fix your recruiting process
b. her manager didn’t do a good job in defining the framework and helping her to succeed
as you can see, this is a recursive function that comes right to you if something goes wrong and you also have the same parameters.
