Artifact Lifecycle Discovery
Artifact-centric modeling is a promising approach for modeling business
processes based on the so-called business artifacts - key entities driving the
company's operations and whose lifecycles define the overall business process.
While artifact-centric modeling shows significant advantages, the overwhelming
majority of existing process mining methods cannot be applied (directly) as
they are tailored to discover monolithic process models. This paper addresses
the problem by proposing a chain of methods that can be applied to discover
artifact lifecycle models in Guard-Stage-Milestone notation. We decompose the
problem in such a way that a wide range of existing (non-artifact-centric)
process discovery and analysis methods can be reused in a flexible manner. The
methods presented in this paper are implemented as software plug-ins for ProM,
a generic open-source framework and architecture for implementing process
mining tools
The perceived quality of process discovery tools
Process discovery has seen a rise in popularity in the last decade for both
researchers and businesses. Recent developments mainly focused on the power and
the functionalities of the discovery algorithm. While continuous improvement of
these functional aspects is very important, non-functional aspects such as
visualization and usability are often overlooked. However, these aspects are
considered valuable for end-users and play an important part in the experience
of these end-users when working with a process discovery tool. A questionnaire
has been sent out to give end-users the opportunity to voice their opinion on
available process discovery tools and about the state of process discovery as a
domain in general. The results of 66 respondents are presented and compared
with the answers of 63 respondents that were contacted through one particular
software vendor's employee and customer base (i.e., Celonis)
Model-driven Enterprise Systems Configuration
Enterprise Systems potentially lead to significant efficiency gains but require a well-conducted configuration process. A promising idea to manage and simplify the configuration process is based on the premise of using reference models for this task. Our paper continues along this idea and delivers a two-fold contribution: first, we present a generic process for the task of model-driven Enterprise Systems configuration including the steps of (a) Specification of configurable reference models, (b) Configuration of configurable reference models, (c) Transformation of configured reference models to regular build time models, (d) Deployment of the generated build time models, (e) Controlling of implementation models to provide input to the configuration, and (f) Consolidation of implementation models to provide input to reference model specification. We discuss inputs and outputs as well as the involvement of different roles and validation mechanisms. Second, we present an instantiation case of this generic process for Enterprise Systems configuration based on Configurable EPCs
