About DEC2H

Workshop Theme

Processes and business process models involve rules and decisions describing the premises and possible outcomes of specific situations. However, rules and decisions are often implicit in process flows, process activities or in the head of employees (tacit knowledge). To make them explicit, they must be discovered using state-of-art techniques. For knowledge-intensive processes, it is common that rules and decisions, as opposed to the process-flow, define the allowed behaviour of a process. For example, the major purpose of an insurance claim process is to ensure that the rules governing the claim are being followed and to arrive at a final decision.

In particular, Knowledge-intensive Processes (KiPs) rely on such rules and decisions to guide the workflows of all process stakeholders. Examples include checking creditworthiness in a financial process, claim acceptance in an insurance process, eligibility decisions in social security, etc. These are highly variable situations, and the processes supporting them are very flexible by nature. This variability and flexibility calls for explicit statement of the underlying rules and decisions when describing such processes.

While traditional imperative notations such as BPMN excel at describing “happy paths”, they are inadequate for modelling rules and decisions. This follows from the fact that imperative notations describe possible behaviour as alternative, restricted flows. Encompassing all possible variations makes imperative models cluttered and thus impractical in highly flexible scenarios. Against this background, a new declarative modelling paradigm has been proposed that aims to directly capture the business rules or constraints underlying the process. The approach has gained momentum, and in recent years several declarative notations have emerged, such as Declare, DCR Graphs, DMN, CMMN, GSM, eCRG, and DPIL.

In this workshop, we are interested in the application and challenges of decision- and rule-based modelling in all phases of the BPM lifecycle: identification, discovery, analysis, redesign, implementation and monitoring. Contributions may include completed work (research, case studies and tools), but also work-in-progress and position papers.

Purpose of the workshop

The purpose of the workshop is:

  • To examine the relationship between rules, decisions and processes, including models; not only to model the process, but also to model the rules and decisions.
  • To enhance rule and decision mining based on process data (e.g., event logs).
  • To examine decision goals, structures, and their connection with business processes, in order to find a good integration between rule- and decision-based modelling and flow-based modelling.
  • To examine standards (DMN, CMMN, BPMN) and their integration.
  • To study how different process models can be designed to fit a decision process, according to various optimization criteria, such as throughput time, use of resources, etc.
  • To study the integration between declarative models with traditional imperative models.
  • To show best practices in separating process, rule and decision concerns.

Paper submission

Submission guidelines

Prospective authors are invited to submit papers on any of the topics of the workshop. We are interested in research, work-in-progress, position, case-study and tool papers, either in long (not exceeding 12 pages) or short (not exceeding 6 pages) format. Only papers in English will be considered. Submitted papers must present original research contributions not concurrently submitted elsewhere.

Submissions must be prepared according to the Lecture Notes in Computer Science (LNCS) format specified by Springer (see instructions). The title page must contain a short abstract and a list of keywords, preferably using the list of topics given above. Papers must be submitted electronically via EasyChair: enter the main conference installation (BPM 2019) and select “(Workshop on DEClarative, DECision and Hybrid approaches to processes)” as the submission track.

At least one author of each accepted manuscript must register for the workshop and present the paper. Registration is subject to the terms, conditions and procedure of the main BPM 2019 conference to be found on its website.

Submission categories

At the moment of the submission, the portal will ask the authors to specify one of the following contribution categories:

Research paper
Papers reporting on the results of original research.
Work-in-progress / position paper
Papers reporting on significant intermediate results that would benefit from discussion in the community, though not complete yet. Position papers propose new ideas which have yet to be investigated (e.g., making a convincing case for a significant new hypothesis), or a new research agenda for a field relevant to the workshop.
Tool paper
Papers describing new software tools relevant to the workshop. Authors are encouraged to include significant technical details.

Papers reporting on the use of existing technologies in an organizational setting (case study papers) are also welcome. Depending on the maturity of the study, they could be submitted as research papers or work-in-progress papers.

Each manuscript will be reviewed by at least three program committee members guaranteeing that only papers presenting high quality work and innovative research in areas relevant to the workshop theme will be accepted. All accepted papers will appear in the workshop proceedings. The pre-prints will be made available before the workshop starts. The post-proceedings will be published by Springer in the Lecture Notes in Business Information Processing (LNBIP) series, in a single volume dedicated to the proceedings of all BPM 2019 workshops. During a time window after the conference the workshop participants will be granted the free download of the papers.

Special Issue

Depending on their quality, the authors of selected papers in DEC2H will be invited to submit revised and extended versions of their work for a special issue in the Journal on Data Semantics (JoDS), edited by Springer. The special issue is organised together with the chairs of the Workshop on Process Querying (PQ), held in conjunction with BPM 2019.

Marco Montali, Putting Decisions in Perspective(s)

Abstract

The advent of the OMG standardization effort on the Decision Model and Notation (DMN) has revived interest, both from academia and industry, in decision management and its relationship with business process management. From the technical point of view, many analysis tasks to check for correctness, refactor, and optimize decision models are now being studied by exploiting the specific modeling choices adopted by the standard. In particular, the S-FEEL DMN language provides an interesting trade-off between expressiveness and computational tractability. In this short paper, I argue that decisions have to be put in perspective, that is, understood and analyzed not in isolation, but in a concrete organizational context. I consequently show how even more challenging analysis tasks arise in this case. Specifically, using a simple but illustrative example, two concrete perspectives are considered: background, structural knowledge of the domain of interest, and (data-aware) business processes routing cases based on decisions. I report on how we successfully tackled decision analysis tasks in both settings, through a balanced combination of conceptual modeling, formal methods, and knowledge representation and reasoning.
