# Theory behind the PARA method [[Tiago Forte]] has shared some details about the theory behind the [[PARA method]]: 1. Kanban: pieces of work move linearly through discrete stages 2. Work-in-process limits: each stage has limited slots that can be filled 3. LIFO: most recently accessed info is kept most accessible, because it will likely be needed the soonest 4. Info hierarchies: the most important info should be visually distinguishable, and therefore most accessible 5. "Small world" property: smaller agglomerations of info are healthier than a single homogeneous network 6. Stocks vs. flows: projects are discrete stocks, whereas areas are continuous flows of info 7. Flat hierarchies: no more than 2 layers allowed, preventing silos 1. Aka the [[LIFT principle]]
