This allows us to focus on the role that process models play in process science, rather than worrying about notation. Although process mining can be used in a variety of applications domains, we often assume a BPM context for clarity. , in healthcare logistics, luggage handling systems, software analysis, smart maintenance, website analytics, and customer journey analysis). What are process models used for? • insight: while making a model, the modeler is triggered to view the process from various angles; • discussion: the stakeholders use models to structure discussions; • documentation: processes are documented for instructing people or certification purposes (cf.
The market capitalization of Facebook in November 2015 was approximately US $300 billion while having approximately 1500 million monthly active users.

These numbers illustrate the economic value of data and the success of young companies based on new business models.
Do they change over time? • What do the cases that take longer than 3 months have in common? Where are the bottlenecks causing these delays? • Which cases deviate from the reference process? Do these deviations also cause delays? Obviously, these questions cannot be answered using spreadsheets because the process perspective is completely absent in spreadsheets. Processes cannot be captured in numerical data and operations like summation. Process models and concepts such as cases, events, activities, timestamps, and resources need to be treated as first-class citizens during analysis.
