Lean Enterprise is based on the premise that anywhere work is being done which of these is also occurring?

The foundational premise of Lean Enterprise, derived from the Toyota Production System, is that any process or work activity contains waste (Muda). Lean philosophy posits that waste is any step or action that consumes resources but does not add value from the customer's perspective. The primary goal of Lean is to systematically identify and eliminate this inherent waste through continuous improvement, thereby maximizing value and optimizing workflow. Therefore, wherever work is being done, it is assumed that waste is also being generated.

A. While work involves spending money, this is a general business fact, not the specific operational premise that drives Lean methodology's focus on process improvement.
C. This is the desired outcome or goal of a process, not the assumed reality. Lean operates on the premise that much of the work being done is non-value-added (waste).
D. This is the objective and activity of applying Lean principles. The premise is that waste exists to be eliminated, not that it is already being eliminated.

D. T. (2003). Lean thinking: Banish waste and create wealth in your corporation. Simon and Schuster. In Chapter 1

the authors define Lean thinking starting with specifying value

which inherently separates value-added activities from non-value-added activities (waste). The premise is that waste exists in all processes (p. 15).

" which involves defining value from the customer's perspective to recognize what is waste. The second principle

"Map the Value Stream

" is used to "identify and document all the activities... both value-added and non-value-added (waste)." This confirms the premise that waste is present to be identified.

reinforcing that the presence of waste is the fundamental premise. https://doi.org/10.1108/01443570410558049
