Data picking list

Force field analysis
The force field analysis is a useful tool to identify both, factors which bind forces and inhibit or block changes as well as those which release forces and thus promote change throughout change processes.
Problem decision program chart
The problem decision program chart organizes thoughts on existing or planned processes and illustrates the connections graphically, quickly, and clearly. To be able to do so, the process is broken down into substeps. Each problem that can arise within a substep is listed along with a possible solution.
Spaghetti diagram / movement map
