...practical and simple,
Problems that cannot be solved
Constantly solving the same problem
Repeated complaints from customers (external/internal)
Constantly discussing problems without using data and formal structure
Areas of poor performance
My trainings are practical and tailored to the client's everyday challenges. They focus on the most useful tools, which I teach through "activity-based learning", i.e. effective interaction between the trainer and the participants, where 30% of the training time is spent on practical exercises.
I teach "theory" only to the extent that it is needed by practitioners in their improvement projects, and I translate the necessary statistical concepts and calculations in a user-friendly manner.
... then SIGMA Value is the solution.
My name is Tomasz Leśniewicz and I run SIGMA Value - a boutique training and consulting practice whose mission is to provide knowledge on effective problem solving and quality improvement using data, Six Sigma tools and critical thinking.
I am also an advisor helping organizations to plan and implement projects aimed at improving products and services and reducing costs.
The biggest challenge facing the Six Sigma training community is the proliferation of unqualified and incompetent consultants and trainers without practical business experience.
Many of them teach tools without context that are ultimately not used. Moreover, they present very complex statistical concepts (mostly with factual errors), which are needed only in 1% of situations.
In contrast, SIGMA Value training focuses on creating value by providing everything the client needs to make problem solving more effective. Practical and simple. Action-oriented.
