Before the Agile manifesto, before Scrum/XP/Lean became popular, I had my own way of delivering software which basically was: meet with users/stakeholders, talk about what they need, build a first version in 2 to 4 weeks, release, test, adjust, repeat. For me it makes so much sense agile that I don't get why some devs don't understand the beauty and simplicity of it.
