May I ask if you didn't have enough experience how/why were you allowed to make such decisions? Is this common in some companies that anyone can make fundamental decisions regardless of number of years in service or experience with the technology?
Sure! The issue is best described as the Peter principle. They guy who hired me didn't know enough to hire the right person. He was beyond his capacity and then it was me. That's the Peter principle. At some point in our career this might happen to allot us. We get promoted into a position we're not capable of.
