What is the focus of Lean Thinking?

The central focus of Lean Thinking is to maximize customer value by minimizing waste. A primary form of waste in knowledge work is delay. Therefore, Lean places a significant emphasis on achieving a continuous and smooth flow of value, which is accomplished by identifying and reducing or eliminating delays in the value stream. SAFe Principle #6, "Make value flow without interruptions," directly addresses this by focusing on reducing batch sizes, managing queue lengths, and limiting Work in Process (WIP). These practices are all aimed at minimizing delays to accelerate value delivery.

A. Respect for people and culture is a foundational pillar of the SAFe House of Lean, but the primary focus is on value flow.
B. Objective measures are important for feedback but are a supporting practice, not the central focus of Lean thinking itself.
D. Moving to an iterative process is a method to achieve Lean-Agile goals, but the core focus remains on eliminating waste, specifically delays.
