Decision Analysis

Definition

Decision Analysis is a technique used to evaluate options and support informed decision-making by comparing alternatives against defined criteria. It brings objectivity and transparency to decisions that might otherwise be driven by intuition or organizational hierarchy. Common approaches include weighted scoring, cost-benefit analysis, risk comparison, and decision matrices.

Inputs

• Clearly defined decision to be made and its scope
• List of viable options or alternatives
• Evaluation criteria agreed with stakeholders
• Stakeholder input on relative importance of criteria (weights)

Outputs

• A scored comparison of options against weighted criteria
• A recommended option with documented rationale
• Inputs to business cases, solution design, and executive decision-making
• An auditable record of how the decision was reached

When to Use

• Choosing between solution options with competing trade-offs
• Vendor or technology platform selection
• Prioritizing initiatives or features under resource constraints
• Any decision that must be defensible to leadership or regulators

When Not to Use

• When there is only one viable option
• When decisions are trivial, low-impact, or already agreed by stakeholders
• When time does not permit structured evaluation and a simpler judgment call is appropriate
