Which set comprises the five LEAN principles?

• A. Specify Value; Value Stream; Flow; Pull; Perfection
• B. Specify Value; Value Stream; Flow; Push; Perfection
• C. Specify Value; Value Stream; JIT; Pull; Perfection
• D. Value; Stream; Flow; Pull; Perfection

Answer: (A)

Lean thinking starts by defining value from the customer’s perspective, then identifying every step that contributes to delivering that value, then creating flow so the work moves smoothly, followed by a pull system driven by actual demand, and finally aiming for continuous improvement toward perfection. The set that lists these five elements exactly as Specify Value; Value Stream; Flow; Pull; Perfection matches this sequence and captures the full framework, making it the best choice. Substituting Push for Pull conflicts the demand-driven nature of lean; treating JIT as a principle inserts a tactic rather than a principle; and omitting the explicit first two steps (Specify Value and Value Stream) leaves out how value is defined and traced through the process.
