Derivative's Software Delivery Process? How are you so fast?

I’m always amazed at how quickly the folks at Derivative ship features. I’ve worked in Software, namely as an embedded engineer and now an iOS developer for the last 15 years, and I’ve never seen the velocity that Derivative seem to have.

Have you ever shared your delivery process anywhere? Things like team structure, roles, ceremonys, agile workflow? I’d love to know the typical flow from say an epic or story through to development/test, and done.

Keep up the great work!

All the best,
