Read the equation
The two inequalities require D_desire to lie in the closed interval from zero to one, including both endpoints. The adjacent component equation defines D_desire as emotional intensity E multiplied by perceived value V and identity alignment I. Constraining each of those three factors to [0,1] would be sufficient to keep their product in the stated range, but the image does not provide such input scales or a normalization rule. The inequality is therefore a declared range for the proposed score, rather than a result established by the multiplication alone.

Terms & definitions
| Term | Meaning in this source |
|---|---|
| D_desire | The desire component of the MADDIE framework. |
| E | Emotional intensity within the Desire box; distinct from the Enrollment symbol E elsewhere. |
| V | Perceived value within the Desire component. |
| I | Identity alignment within the Desire box; distinct from the Investment symbol I elsewhere. |
| ≤ | An inclusive bound, permitting equality at the endpoint. |
How it works
Read D_desire as the product E×V×I defined in the same component box.
Compare the resulting value with both endpoints: it must be at least zero and at most one to satisfy the displayed condition.
Check the input scaling before inferring that the product always satisfies this condition.
Assumptions & limits
The poster supplies no explicit measurement scales or normalization of E, V, and I that would ensure the declared bound.
