What is Dual-Track Agile (Discovery and Delivery)?
Dual-track agile is a way of working that runs two continuous, parallel tracks: discovery, which validates what is worth building, and delivery, which builds and ships it. The tracks feed each other, with discovery producing validated backlog items that delivery turns into working software.

In more depth
Popularised by Marty Cagan and credited to Jeff Patton, dual-track agile is not two separate teams but one team splitting its attention between learning and building. Discovery de-risks ideas through research, prototyping and testing before they enter delivery, so engineering time is spent on validated work. The tracks are continuous and overlapping rather than sequential phases, which avoids a quiet return to waterfall.
Why it matters
When teams build every idea straight into delivery, they waste expensive engineering effort on features that were never validated. Dual-track agile keeps a steady stream of tested, worthwhile items flowing into delivery, reducing waste and risk, while ensuring discovery never becomes an ivory-tower exercise disconnected from what actually ships.
A product example
While engineers deliver last sprint's validated stories, the product manager and designer run discovery on the next problem, prototyping and testing three concepts with users. Only the concept that tests well enters the delivery track, so build effort is never spent on unproven ideas.
