Lean is subset of IE with increased focus on flow and special focus on pull.
Lean is a sub-brand of industrial engineering. Like motion study, time study, method study, lean is also method or sub-brand of industrial engineering.
Lean focuses on temporary storage or delay step in process flow chart. To eliminate delays, lean modifies engineering in other steps. SMED is a modification of operation step. Pokayoke is a modification of Inspection step. Layout changes are modification of mechanical handling steps. Lean also modifies production planning procedures.

Lean & IE
Lean Thinkers have to use Industrial Engineering Tools - especially process charts. [VSM] analysis is at a high level, without many details. To uncover every instance of every type of muda requires a detailed analysis using a portfolio of tools drawn from industrial engineering ... The most important of these are process mapping (to identify and categorize each step together with the time, distance and effort involved)... Womack and Jones, 1996.

LEAN MANAGEMENT
How to plan, organize, resource, direct and control lean systems?
Combine Quality and Productivity Functions.
The traditional quality function should be combined with a productivity (or "lean") function to create an "improvement function" able to eliminate muda of all sorts. - Womack and Jones.
