Michael Hannan Quotes & Sayings

How often have you heard people brag about what great multi-taskers they are? Perhaps you've made the same boast yourself. You might even have heard that members of "Gen Y" are natural multi-taskers, having lived their whole lives constantly switching their attention from texting to IMing to Facebooking to watching TV - all supposedly without missing a beat. We even see training classes designed to teach managers how best to multi-task their Gen Y staff, the implication being that asking someone to focus on a single task through to completion has now become ridiculously old-fashioned for, if not downright heretical to, the new world order.

Interestingly, Agile's scrum-team approach has its own way of aggregating some execution risk. For example, in a traditional "single task owner" approach, the risk of execution is not aggregated at all, leaving that task owner to add a lot of task-level buffer to self-insure and deliver on his commitment. In contrast, a 5-person scrum team aggregates the risk that any single individual will make slow progress, as the other four team members can often make up the deficit.

But why aggregate only up to the scrum-team level? Taking a lesson from the insurance industry, the more that risk can be aggregated, the easier it is to manage. Applied to projects, this will nearly always mean that it's better to aggregate risk at the project level. As a result, an Agile project can improve speed by avoiding sprint-level commitments. — Michael Hannan
