Lean marketing uses agile principles of rapid iteration and frequent validation to provide marketing programs that are focused, competitive, and adaptable. Key aspects of lean marketing include using Scrum processes with sprints and daily standups, collaborative Kanban tools, testing ideas through small experiments rather than large campaigns, and basing budgets on acquisition and retention metrics rather than soft goals. The overall goal is to achieve more marketing results with less waste of time and money through an agile approach.
