Our parent organization, KT recently published this white paper that speaks directly to all decision-making leaders.

In every organization, decisions must be made and actions taken. Usually the realm of decision making is the responsibility of leaders. They must select the actions, determine how they will be carried out, and be accountable for the implementation of the decision and for the subsequent results.
Gut feelings and years of experience may be sufficient for most day-to-day decisions, but major decisions that move an organization forward come with a real element of risk. Leaders need a structured process that is based on an informed analysis and participation from key stakeholders to arrive at a balanced decision that everyone can support.
