Uber may have made the wrong call in unifying SignUp and Login. Here is why.
Did Uber make a mistake unifying SignUp and Login? I think so.
Uber has data and experience within its teams that I can hardly fathom let alone compete against. Thus, take my opinions with a pinch of salt — but here they are anyway :-) !! Here is the awesomely laid out blog from Uber Engineering regarding this. For what its worth — I love going through the engineering blogs of various tech companies and if you are interested in technology and building your technical acumen, you should go through them a few times a month as well. Anyway, back to the article now.
Background of why Uber got to a point of taking a decision for this
When companies grow and start splitting into multiple lines of businesses (LOBs), various calls have to be made and bets revisited (says the armchair VC in me anyway, lol). This is because teams are more likely to over-index on the downside to current functionality, existing processes, used technology, and decisions that have been made — all of which they may or may not have been part of at the outset. When that happens, you don’t have the entire context of why any decisions made worked so well and may have also been taken with the long-term view in mind.
