Recently, on my first software job (freelance) I messed this up. I had very little opportunity for contact with the client and they were slow and unreliable with providing feedback. I could tell we would go over schedule if I didn’t produce a lot more work with each feedback cycle and I desperately wanted to do a good job so I let myself get weighed down with imagining things that they might think I was stupid for not including in each version.
I am still unsure of how I should have approached this, but I know I messed up because at the end it was just way too much effort to fix bugs and add features, but I didn’t have the time to refactor. If anyone has advice, I would be grateful.
