Risk & Decisions · How-to
Run a Trade Study and Record the Decision
Compare alternatives against weighted criteria, test the result's sensitivity, and record the choice on a Decision.
- Open Risk & Decisions → Trade Studies and click + New Trade Study. Choose or create the Decision it supports.
- Add alternatives with + New (creates an Asset) or + Existing….
- Add criteria, or choose ✦ AI ▾ → Suggest Criteria from Requirements and MOEs… and pick the ones to keep. Set each criterion's Weight, Improvement Direction, Units and Scoring Method.
- On the Decision Matrix tab, enter a value for each alternative and criterion, or click Pull Values from Model. The weighted scores and the Ranking chart update as you type.
- Optionally compare against a datum on the Pugh Matrix tab (Fill from Scores sets it from the decision matrix).
- On the Sensitivity tab, check the Weight Sweep, Tornado and Rank Reversal Points. Robust means no weight change within range alters the leader.
- Click Record Decision…, choose the alternative, and write or draft (✦ AI ▾ → Draft Decision Rationale…) the rationale. The Decision gets its choice, justification, date, decider and Status = Decided as one undo step.
- Download the study with Export ▾ (Excel workbook or Word summary).
