|---|---|---|---|---|
Purposedifferent | VMGS arranges vision, mission, goals, and strategies into a clear guiding logic. Direction, purpose, and priorities are connected so teams can decide more coherently. | For a risk that can only be managed through multiple layers of protection, the method examines the effectiveness of each barrier. It shows where safeguards are missing, too weak, or fail under real conditions. | For a deviation after a change, the method isolates the influence of the altered condition. It narrows down which differences are relevant and which are just accompanying noise. | For an event with a complicated course, the method breaks down the contributing factors along the timeline. It shows how conditions, decisions, and reactions together produce a course of events. |
