This blog post is part of a blog post serie about humantask assignment. You can find the starting point of this series by following the next link.
If you look at the example in Humantask Assignment: not the same lane participant as previous task (four-eyes principle) you see two sequential humantasks. If these humantasks are both connected with the same task form there might be another method available to model the four-eyes principle. Namely: assigning participants sequentially to the same humantask. This means that there will be only one humantask in the process model.
