Humans have been baking bread for thousands of years. At this very moment I could find 100 sources of information, free and for sale about the specifics of baking bread. I could get these in the context of baking at home, baking for a group, or baking for commerce.
Contrast that with the poster's problem of implementing an architecture for an identity access management system. (I have experience with this).
There is no way to relate the tasks involved in baking for profit to designing and building a working technical system that likely is highly unique to the technologies and circumstances of his environment.
I quite sure IBM could set out to design and build 500 profitable bakeries with their own people and be successful on upwards of 90% of cases. Those people setting out to build 500 different <insert your favorite complex computer system here> would fail upwards 50%.
I'm not saying running a bakery is easy, but I am saying running a bakery is less stressful than implementing a functioning computer system.
