The Problem With the v Model in Software Development

In the traditional V model of software development, you go through a series of stages. The first stage is to design an architecture and then break that down into smaller components until eventually you arrive at the unit level. At each level, you basically validate the design that happened on that same level as you were going down. It's interesting that it's so different from what some people practice as agile development or things like that. But we have this field of tension here where like, these are both legitimate concerns.
