A typical response to a risky process is to do it as rarely as possible. Thus there is a temptation to do as few releases as possible. The result is “mega-releases” launched only a few times a year. However, by batching up so many changes at once, we actually create more risk. How can we be sure thousands of changes, released simultaneously, will all work on the first try? We can’t. Therefore we become even more recalcitrant toward and fearful of making changes. Soon change becomes nearly impossible and innovation comes to a halt.
