The agile mindset shares significant common ground with other progressive approaches to product development. There aren't clear boundaries between agile, lean, and design thinking mindsets. Their overlaps are normal and expected. It's beneficial to mix and match these approaches and accept the natural fuzziness between them. Lean thinking similarly emphasizes eliminating waste, focusing on customer value, and making decisions based on evidence. Design thinking complements agile through its focus on empathy, problem framing, and creative solution generation.

All these mindsets aim to break down boundaries and walls between team members and functions. These approaches all emphasize working side-by-side in cross-functional teams rather than working in isolation and "throwing things over the wall." For those uncomfortable with highly communicative and collaborative environments, organizations that adopt these mindsets might not be the right fit. The boundaries between these mindsets intentionally blur, allowing teams to draw from multiple approaches depending on their specific challenges.
