Yes and no, decision is not the only problem. Some people tend to default to ask for someone's help everytime they get blocked. Or managers drop a quick "ask Bob, he already did something similar", which might be ok on the short term because Bob might indeed give you the answer, but Alice didn't spend the time struggling and learning to be independent in the process, and Bob gets buried in random requests that prevent him from shipping his own stuff.

It's not a clear cut thing, definitely helping each other is useful, but like everything there's a balance, and striking it is bot straightforward
