We develop the basic properties of $ w$-simple-minded systems in $ (-w)$-Calabi-Yau triangulated categories for $ w \geq 1$. We show that the theory of simple-minded systems exhibits striking parallels with that of cluster-tilting objects. The main result is a reduction technique for negative Calabi-Yau triangulated categories. Our construction provides an inductive technique for constructing simple-minded systems.
