I have come to believe that, when weighting design factors that influence overall product development and maintenance cost, nowadays most people will choose an exponential curve over a logarithmic curve. Because when you're just getting started, you're just looking at what's immediately in front of you. Logarithmic curves go up quickly in the beginning. Exponential curves are nice and easy in the beginning. The fact that one levels off and the other keeps turning ever more sharply upwards doesn't matter. Thinking ahead like that, considering second-order effects, etc., is neither Lean nor Agile, and invites accusations of engaging in Analysis Paralysis.
