Comparison of the merged process logs analyzed with the heuristics miner and a manu-
ally designed BPMN process model
Whereas the BPMN model provides more details about the participating roles due
to its notation, the process segment of the mined To-do's offers information about
how often the operations were considered in the logs (and thus in the To-do's of the
process participants) and provides a more precise insight into the actual operations
(e.g. several process participants explicitly mentioned the conduction of the prelimi-
nary unit, operations that were performed to fix the participants of the course, and
operations among lecturers before a course unit was conducted).

Process design is one of the main phases of the business process life cycle. There are
basically two different approaches of process design that can be distinguished. First,
business process (re-)engineering refers to the systematic process exploration based
on methods such as interviews and the subsequent modeling of as-is processes, fol-
lowed by an optimization of these processes (to-be processes). Much work has been
spent on questions such as process modeling notations [17]. Only few approaches
tackle process redesign [4]. Although there are known common practices to elicit
process models, like questionnaires and workshops, no systematic approach for
process exploration and design based on activities and tasks representing practical
processes of work of single persons sorted in treated chronological order (To-Do's)
has been presented yet. We utilize existing process mining algorithms [18] for our
work not only to mine instances of the whole process but also operations that are
performed by a single agent of the process (process view logs).
