Strength Deployment Inventory
Reduce Friction, Improve Collaboration
The Strength Deployment Inventory (SDI) helps people understand the motives behind behavior so they can navigate differences productively and work better together under pressure.
When Motives are Misread
FRICTION COMPOUNDS
People routinely make judgments about the motive behind others’ behavior. But when those assumptions are wrong, tension escalates, collaboration suffers, and work becomes harder than it should be.
This is one of the most common—and least recognized—sources of workplace friction and execution breakdown.
The SDI helps people understand the motives behind behavior so they can interpret interactions more accurately and respond more effectively—especially in high-pressure moments when results are on the line.
