My suggestion

CŨng có nơi dùng là "doanh nghiệp sản xuất tinh gọn".
WIKI: Lean enterprise is a practice focused on value creation for the end customer with minimal waste and processes. The term Lean Enterprise historically has been associated with Lean Manufacturing and Six Sigma (or Lean Six Sigma) due to lean principles being popularized by Toyota in the automobile manufacturing industry and subsequently the electronics and internet software industries.

Tuy nhiên lean enterprise rộng hơn lean manufacturing, không chỉ bao gồm về sản xuất mà còn về dịch vụ và quy trình:
As lean concepts took hold in manufacturing, a
broader realization began to occur. This realization
is that lean is not something to be “done to
manufacturing,” but it is a way of thinking that
applies beyond the production floor and can
apply to any and all processes, including the
administrative support to manufacturing, new
product design, sales & marketing processes,
finance & accounting, and corporate offices—
anywhere there are processes containing wasteful
work. Companies in the service sector also
began to recognize that any product that is the
result of a process can be viewed through a lean
lens. Thus the common term “lean production”
is considered too narrow to incorporate the
impact and scope of lean concepts. The term
“lean enterprise” more appropriately describes a
way of thinking about manufacturing, service,
and support processes that is now used increasingly
across a wide variety of companies and
product offerings.

Henry Ford defined the lean concept in one sentence: “We will not put into our establishment anything that is useless.”

Lean manufacturing is a system of techniques and activities for running a manufacturing or service operation. The techniques and activities differ according to the application at hand but they have the same underlying principle: the elimination of all non-value-adding activities and waste from the business.

Lean enterprise extends this concept through the entire value stream or supply chain: The leanest factory cannot achieve its full potential if it has to work with non-lean suppliers and subcontractors.
