The document summarizes a school board work session on process improvement and Lean methodology. It provides an overview of Lean, which aims to minimize waste and non-value-added work. Lean relies on 5 key principles: defining value from the customer perspective, understanding existing processes, standardizing efficient processes, producing only to meet demand, and continuously seeking improvement. The document identifies 7 types of waste that Lean helps reduce, such as overproduction, waiting, defects, and underutilized staff. It gives examples and symptoms of each waste type. The goal of Lean is to accelerate process improvement through engaging staff and data-driven problem solving.
