Dual-track development

Dual-track developmentDual-track development: a discovery track and a delivery track running in parallel, with validated ideas flowing down and production learning flowing back upDiscovery trackLearn fast: is it valuable, usable,feasible, viable?Delivery trackBuild well: predictable, highqualityFrame problemoutcome, risksPrototype, spikefeasibility earlyTest with usersevals, partnersKilled or changedmost ideas end hereSprint nbuild, test, releaseSprint n+1build, test, releaseProduction learningexperiments, SLOs, supportsignalsvalidated idea, ready to buildlearning feeds the next round of discovery

Dual-track development is one team doing two kinds of work at once. Discovery retires value, usability, feasibility and viability risk before delivery invests in production quality, and what ships feeds evidence back into discovery.
