"Whats the easiest way to get something out so that we can test and measure assumptions." I was focusing less in my comment on time-to-market and more on risk aversion to code ownership. But, to address your concern, doing things the right way up front can often cost less time and money than doing it the wrong way and working around the brokenness. This can be truth for both initial time to market as well as the more obvious long-term maintenance costs. At the end of the day it's a calculated judgement call, and I've seen senior engineers get it wrong as well as juniors.
