Purposedifferent | When a project, incident, or change process is only remembered in fragments, Timeline brings the sequence back into a readable form. It makes turning points, precursors, and after-effects recognizable over the course of time. | When there is uncertainty about the real course of a process, the method brings observation to the place where work happens. It combines perception, follow-up questions, and process knowledge so decisions rest on actual workflows instead of assumptions. | With many similar objects of differing economic significance, the method prioritizes effort by effect. It separates what needs regular steering from what rarely needs attention. | When many tasks compete for the same capacity, it orders work by economic impact. It makes time lost, benefit, and effort comparable together. |
