 +===== Notes =====
 +
 +Questions that face anyone who models processes in BPMN: to what level should the process be decomposed? Is it worth to depict how the task is performed?
 +
 +Although there may be exceptions (see [[#exceptions|below]]), it's generally not worthy because results in overcomplicated diagrams. Detailed instructions are valuable indeed but usually it's better to place them to the task description instead. Add step-by-step instructions, checklists, references to the operations manual etc. Focus on the coordination of tasks performed by different roles on the diagram level.
 +
 +Advanced BPMN modeling tools let user add description to a task and publish diagram accompanied by descriptions and other attributes as a document and/or hypertext. As an example, here is how it looks in [[en:tool:bizagi_modeler]] ({{:en:rule:micromanagement-bizagi.bpm|source file}}):
 +
 +{{:en:rule:micromanagement-bizagi.png?nolink|}}
 +===== Exceptions =====
 +
 +It may make sence to depict the task logic if it's non-linear, e.g. if it contains gateways:
