My job is giving advice to clients. A client recently approached us and asked what to do with product X. There were 3 options - I advised option 2.
Working on another similar case with a different client I reran the options. Option 2 will have cost the original client 90K more than option 1 would have done.
I feel awful for the client and if I’m honest for myself. I don’t know why I missed it the first time. I have just reported my monumental fuck up to my boss. What happens now? To the client and to me?
