Timeboxes are just as effective enabling constraints as WIP limits and SLAs when it comes to stabilizing flow.
They just rely on a different aspect of Little’s Law to do this.

What if I told you the reason you might believe that Littles’s Law doesn’t apply to processes in complex adaptive systems is:
1. Your concept of “Little’s Law” is too narrow.
2. You are measuring the quantities in Little’s Law incorrectly.

Indeed. The amount of time people waste mimicking what the SV companies do instead of figuring their own unique competitive advantage in their own market is astounding!
But we also have an entire industry of “thought leaders” who encourage this.

But nope! Mostly what we're witnessing is the compound interest of advantage.
If you run an engineering org, stop competing for the already pedigreed, and build an org that rewards curiosity, effort, hard work, teamwork, and caring, as well as brains.
