In every PMA we all make decisions about what to write exactly. However, we are never 100% sure that we make the best decision and usually the feedforward and the marks can prove us right or wrong. In a recent PMA though I made up my mind to use a specific model to apply a change. When I made the decision I was pretty sure that it was appropriate and suitable for my case. Nevertheless, when I asked the tutor about it, it proved that I made the wrong decision. Luckily, there was still plenty of time to fix this 'mistake'.
Having that incident in mind, I was wondering what happens when companies face a similar case (not for PMAs of course!). If they make a decision which that particular time seemed to be the right one, but after a while they realize that was actully wrong, what happens next? Some situations are reversible but others not... And is there always enough time to make things right again?
