In working with complexity and looking for resilient organisations the team is often emphasised. Team situational awareness is stronger than a single leader having awareness for example. 'None of us is as smart as all of us' (Ken Blanchard). With that in mind I was struck by the unofficial saying of the UK submarine service 'Either we all come back, or none of us do.' It turns out that submarine services have thought quite a lot about the team work they need to meet that exacting life or death standard.
