The correct answer is: Crisis decision-making
Rationale: Teams are not the best vehicle for crisis decision-making, because group decision-making takes longer, and decisions may protect the team at the expense of the right (possible tough) solution.
Teams are, however, great for decision-making where the hearing of different viewpoints is beneficial. They are also great for ideas generation (think of group brainstorming) and coordination (teams are often cross-functional).
You might have hesitated over 'Co-ordination of geographically dispersed workers', but it is important to realise that distance is now no obstacle to team working (think of virtual teams, connected by IT and communications links).
Pitfalls: Don't forget 'virtual' teams in your thinking.
