Quality can be worse in a long-time cycle project: - Engineers are motivated to slam their feature in, because if they miss the train the next one's not for 12 months. - You get one moment per year to connect with your customers & understand how well/not well your changes worked. This means either riskier things happen or that innovation slows to a crawl.

My 2 cents, speaking from some experience working on long time cycle projects and shorter cycle projects.
