Lean
leadership could be the missing link between toolbox lean and a
sustainable continuously improving organization. More and more
enterprises realize that they have so far basically focused on the
visible parts of lean production systems. Although process optimization
with the various methods like kanban, 5S, SMED, FIFO and many more is
very effective to achieve short term improvements, after a few years,
the lean programs of many enterprises do not meet the expectations
anymore. The common approach can be explained by using the 4P Model. It
consists of 4 levels that are all necessary for a sustainable lean
implementation. The levels are: philosophy (long-term thinking), process
(eliminate waste), people and partner (respect, challenge and grow
them) and problem solving (CIP and learning). All these terms are well-
known. However, most enterprises merely focus on process. Eliminating
waste in all processes has been preponderantly adopted, whereas the
other 3Ps, the “invisible” parts of lean, are less easy to adopt but
equally important for the sustainable implementation. Lean leadership
addresses all 4Ps and provides a methodical system for the sustainable
implementation and continuous improvement of lean production systems. It
describes the cooperation of employees and leaders in their mutual
striving for perfection. By now, many authors have identified the need
for a lean leadership but only few holistic concepts exist. Especially
lower and middle management lacks some clear advices and rules for lean
leadership implementation. Therefore, some indicators for successful
lean leadership were deduced from literature, study results, and
practical experiences of lean implementation. The indicators were found
in advices given on successful lean implementations, but particularly in
mistakes and shortcomings. After reformulating the indicators into
requirements for leaders, they were assigned to the five principles
improvement culture, self-development, qualification, gemba, and hoshin
kanri. These requirements shall help executives in realizing lean
leadership.
