We have a Work Queue that describes Product Initiative relevant work, is ordered by urgency, and that shifts up as completed work is removed from near the top. We must now allocate staff without overwhelming or under-utilizing any individual.
Therefore: Allocate staff to roughly two month's worth of work at the head of the Work Queue. Seek their commitment to work together as needed to understand the real and Implied Requirements, develop suitable specifications, complete or extend a design, assemble tests and implement all aspects of the deliverable.
Expect individuals to apply themselves to their most urgent assigned work. Allow some latitude to compensate for impossible to forecast dependencies between projects and individuals, Expect the work of any given item to be performed with the usual rise and fall of concentration revolving around a burst of decision making that marks the center of a Development Episode.
