The increasing adoption of process-aware information systems (PAISs) has resulted in large process model collections involving different process participants. We present the Clavii BPM platform, which enables end users to participate not only in process model execution, but model creation as well. Clavii o ers a modern user interface with a strong focus on ease of use, unifying di erent aspects of the BPM lifecycle in one tool, i.e., process model editor and process engine. As a result, end users are supported in managing and executing process models.
Process-aware information systems (PAISs) provide support for business
processes at the operational level [
Usually, the creation of business process models is fragmented. To be more precise, process models are created with di erent tools compared to the ones used for model execution. Enabling end users to participate in the entire BPM Copyright c 2015 for this paper by its authors.

The Clavii BPM platform addresses these challenges by supporting users with numerous functions integrated in an intuitive and uniform user interface.
Figure 1 gives an overview of the Clavii BPM platform. Clavii enables users to create (Step 1 ), change (Step 2 ), and abstract process models (Step 3 ) intuitively. Created process models can be shared across registered users (Step 4 ) in order to document (Step 5 ), change, and execute them collaboratively. Users are enabled to execute process models at any time (Step 6 ). Finally, a dashboard allows monitoring executed processes (Step 7 ).

Section 2 introduces the application scenario we use for the demonstration. Section 3 presents the Clavii BPM platform. Section 4 then describes how the application scenario can be supported with the Clavii BPM platform. Finally, Section 5 concludes the paper. 2
{ R1: It should be possible to create BPMN 2.0 process models. { R2: Visual appearance of process models should be adaptable for each user (role) according to his BPM knowledge. In particular, this necessitates process model abstractions; e.g., hiding service tasks from end users. 4 { R3: In order to involve multiple users, process models should be shareable. { R4: Process models need to be enriched with a sophisticated, yet intuitive data ow perspective to support process execution. { R5: Service tasks in process models should be connectable with executable program code. Additionally, user task forms should be generated automatically. { R6: Created process models should be executable at any time, i.e., while designing, modeling, monitoring, or evolving them. Furthermore, modeling should obey the correctness-by-construction principle. In order to support process model execution at any lifecycle stage, process models lacking execution-relevant information, like gateway decisions (cf. Step 5 ), should still be executable.
{ R7: Process instances should be monitored in a respective dashboard. 3
We revisit the scenario and requirements from Section 2 in the context of Clavii.
{ R1: Clavii allows creating an arbitrary number of process models by o ering
an intuitive web interface [
Further notations may be added to the Clavii framework [
In case information provided by a process model is missing for proper execution (e.g., conditional gateways lack correct decisions). Users can provide them during run-time. Additionally, the run-time perspective is seamlessly integrated into Clavii's process modeling environment, allowing for the execution of process models without switching away from the modeling context of the Clavii Web Interface (cf. Figure 4). { R7: Process instances can be monitored as well. To this end, the instance is enriched with additional information, like execution times of tasks (cf. 1 in Figure 4).
These aspects are illustrated by a screencast on the project's website: www.clavii.com/screencast. 5
In the demo, we present the Clavii BPM platform and its key functions as proof-of-concept to allow for the collaborative creation and execution of process models. A modern web-based user interface o ers an intuitive way to manage process models.
The Clavii BPM platform is implemented as a web-based application platform. This allows users to simultaneously change and execute process models. Furthermore, user experiments are planned in order to systematically analyze whether the evolution of large process models can be improved by using the Clavii BPM platform. Overall, we believe that the Clavii BPM platform o ers promising perspectives for small and medium businesses lacking BPM expertise.
