Any construction worker will tell you a 20-oz framing hammer, the perfect size and weight for driving structural nails into solid wood framing, is not the right hammer for finish work.

Understand your requirements. You may not need a scaled agile framework if your four-person team is just getting an initial project built. And while lean design principles are great for just about everyone including software products, hardware products, or services, building a heavy process around lean can wait until you’ve got the volume and resources to justify the investment.
The right tool for the right job. Take the time to understand the job you’re doing, select the right tool, and add more as you go.
