Wrangling Your Spikes and Research Stories

We know we're supposed to be dividing our work into small, deliverable chunks and reflecting that on our boards. But what should we do with the occasional tasks that don't exactly have a tangible deliverable at the end of them (e.g. research, proof of concept)?  In this episode, we're helping you build a policy for when spikes and research stories come along so you can stop trying to retrofit abstract tasks into user stories and keep your board flowing with deliverable value.
