I’ve wondered for ages what the meaning of the graph is in this shot of a whiteboard, taken some months ago. I’m guessing “collab” is short for “collaboration” and is not actually C.O.L. Lab or somesuch acronym. The natural assumption is that the x-axis is time (inception, project, BAU run left to right in time). The y-axis baffles me. Productivity? Cost? A lapse in concentration by whoever drew it? Running into a wall?
