  Lean Six Sigma (LSS) is a comprehensive and powerful strategy for processes
improvement and products. There is a cornucopia of tools for its implementation
and 37 among them were selected to carry out an evaluation based on three
factors, namely: Frequency of use of the tool, difficulty in implementing,
importance and impact of the tool in the implementation of LSS. An online
survey was conducted with Portuguese consultants and it included questions on
the profile, and the companies they worked, as well as the degree of impact of
the tools used. Consultants were asked to choose ten tools, ranking them in
order of importance. The frequencies with which each tool had been cited were
counted. A procedure was then developed to identify the know-how of consultants
to establish a ranking of LSS tools. It was created an ordering list of tools,
which emphasized in: Honshin Kanri, VOC, VSM. The results presented are
particularly relevant when is considered the importance of understanding the
requirements for a successful implementation of Lean Six Sigma management
system in the organizations.
