SUMMARY:Exploration of Workflow Management Systems Emerging Features from 
 Users' Perspectives
DESCRIPTION:Workshop\n\nExploration of Workflow Management Systems Emergin
 g Features from Users' Perspectives\n\nMitchell, Pottier, Jacobs, Ferreira
  da Silva, Rynge...\n\nThere has been a recent emergence of new workflow a
 pplications focused on data analytics and machine learning. This emergence
  has precipitated a change in the workflow management landscape, causing t
 he development of new data-oriented workflow management systems (WMSs) as 
 opposed to the earlier standard of task-oriented WMSs. In this paper, we s
 ummarize three general workflow use-cases and explore the unique requireme
 nts of each use-case in order to understand how WMSs from both workflow ma
 nagement models (task-driven workflow management models and data-driven wo
 rkflow management models) meet the requirements of each workflow use-case 
 from the user's perspective. We analyze the applicability of the two main 
 workflow models by carefully describing each model and by providing an exa
 mination of the different variations of WMSs that fall under the task-driv
 en model. To illustrate the strengths and weaknesses of each workflow mana
 gement model, we summarize the key features of four production-ready WMSs:
  Pegasus, Makeflow, Apache Airflow, and Pachyderm. Of these production-rea
 dy WMSs, three belong to the task-driven workflow management model (i.e., 
 Pegasus, Makeflow, Apache Airflow) and one belongs to the data-driven work
 flow management model (i.e., Pachyderm). To deepen our analysis of the fou
 r WMSs examined in this paper, we implement three real-world use-cases to 
 highlight the specifications and features of each WMS. The application of 
 these real-world use-cases demonstrates how each workflow management model
  operates with the different applications. We present our final assessment
  of each WMS after considering the following factors: usability, performan
 ce, ease of deployment, and relevance. The purpose of this work is to offe
 r insights from the user's perspective into the research challenges that W
 MSs currently face due to the evolving workflow landscape.\n\nTag: Worksho
