History

At the end of 1890, Frederick W Taylor
became the first to study work management
scientifically and distribute the results.
His work led to the formalization of time
and motion studies and the setting of
common standards.
Frank Gilbreth then added the concept of
breaking work down into elementary time
blocks.
It was around this time that the first notions
of eliminating waste and studying movement
began to emerge.
In 1910, Henry Ford invented the assembly
line for his standardized Ford Model T.
Alfred P. Sloan improved on Ford’s system
when he introduced the concept of assembly
line diversity at GM.
After the Second World War, Taiichi Ohno
and Shingeo Shingo created the “Just In
Time”, “Waste Reduction” and “Pull System”
concepts for Toyota, which, together with
other flow management techniques, resulted
in the Toyota Production System (TPS).
The TPS has been evolved and improved ever
since.
In 1990, James Womack summarized these
concepts to create Lean Manufacturing at a
time when Japanese expertise was spreading
to the West and the success achieved by
companies applying these principles and
techniques became undeniable.
The Lean Manufacturing house can only grow
if its foundations are built first.
Without using a highly flexible and modular
system that allows muda to be eliminated and
Kaizen attitudes to be introduced into the
plant, it is impossible to proceed to the later

The 7 mudas
Lean Manufacturing identifies
7 areas of waste or «muda».
steps of Lean Manufacturing, which are work
standardization, sequencing (Heijunka) JIT and
JIDOKA. The systematic use of LeanTek ® acts
as a catalyst for the policy of waste reduction
and as a tool for implementing the Kaizen
attitudes of continuous improvement.
