5S / 5A
“5S action“ is a simple, visual and clearly defined method to obtain long-lasting clarity and structure at the workplace and to preserve it in five steps. As a result, this action reduces waste and ensures more effective work. The obtained standardized order can be seen as the foundation to increase workplace efficiency.

BPMN
BPMN (=Business Process Model and Notation) is a method to model processes graphically in a standardized way. The standard includes a guideline that regulates the look of components of the process illustration (notation). Furthermore, possible connections between those components are standardized (syntax) as well as their meaning (semantics).

Change Architecture
The “change architecture“ is a precisely elaborated and coherent “end-to-end” change concept – from the first announcement, to the accomplishment of critical phases, up to the successful completion. It has a consistent logic which explains how the planned procedure leads to the changes targeted.
