In a more traditional workflow, you have to decide who is next in line, unless the workflow is linear and "single file" only. We believe this is suboptimal. Your only concern should be whether you are done.
Our gateflow is a bit different. A gateflow consist of many gates, each representing a set of work to be done. Each gate has a gate keeper who decides when the work is finished and then close the gate. When Gates are closed, new gates may open up.
