All models are wrong, some models are useful

That’s what makes it a model. The map is not the territory, and a model is nothing but a stripped-down approximation of what might be happening. By definition, the model for your problem, your organization, your opportunity–it’s not actually the thing being studied, it’s a simplified version of it.

At higher magnification, your model is wrong. It has to be in order for it to be a model.

And yet we need models.

We need a model because if the elegant, pure, refined model doesn’t work, it’s harder to understand why your messy, real-world situation is going to work.

Not all logical and structurally sound models turn into successes in the real world, but better to begin with something that makes sense.
