Dissatisfaction × Vision × First steps must beat Resistance — and because it multiplies, any zero kills it.
Developed by David Gleicher and popularised by Richard Beckhard and Reuben Harris.
Three things have to be present for change to happen, and they multiply rather than add. If any one of them is zero, the whole thing is zero, no matter how large the others are.
D × V × F > R
D — dissatisfaction with how things are now. Without it, nobody moves; comfort is a powerful anaesthetic.
V — a vision of what is possible. Dissatisfaction with no vision produces complaining, not change.
F — concrete first steps. Dissatisfaction and vision with no idea what to do on Monday produces frustration.
R — resistance, the cost of changing: effort, risk, loss of status, loss of the familiar.
Because the left side multiplies, you cannot compensate. A brilliant vision and a detailed plan achieve nothing in a business where everyone is quite comfortable. Overwhelming dissatisfaction with no plan produces churn and exits.
It also tells you where to intervene: find the zero rather than pushing on whichever factor you find easiest.
