Eisenhower knew that any plan crafted before battle would be obsolete at first contact with the enemy. In his work, Kavazovic wants to be this realistic too. “Translating this into tech: no long-term plan or product vision survives contact with the user in the product-design sense. That’s why agile methodology is specifically designed to create user experiences that work,” he says. “It’s absolutely suboptimal to design a particular product all the way down to years’ worth of features, make that the blueprint, and build it out.” Inevitably, sticking to a rigid long-term plan without a mechanism to iterate on user feedback would result in features users don’t want, costly re-dos and potentially total product failure.
