Modeling process flow using diagrams

Modeling process flow using diagrams

In the practice of process improvement, tools such as the flowchart, the value-stream map (VSM), and a variety of ad hoc variants of such diagrams are commonly used. The purpose of this paper is to present a clear, precise, and consistent framework for the use of such flow diagrams in process improvement projects. The paper finds that traditional diagrams, such as the flowchart, the VSM, and OR...

Tracing the Process of Process Modeling with Modeling Phase Diagrams

The quality of a business process model is presumably highly dependent upon the modeling process that was followed to create it. Still, there is a lack of concepts to investigate this connection empirically. This paper introduces the formal concept of a phase diagram through which the modeling process can be analyzed, and a corresponding implementation to study a modeler’s sequence of actions. ...

Modeling Control Flow with Activity Diagrams

The Unified Modeling Language (UML) 1 is a visual, object-oriented, and multipurpose modeling language. While primarily designed for modeling software systems, it can also be used for business process modeling. Since the early 70s, a large variety of languages for data and software modeling like entity-relationship diagrams [2], message sequence charts [5, 10], state-charts [9], etc. have been ...

Representing Control Constructs in Object-Flow Process Diagrams

Compositions of command statements, branching, iteration and recursion are primarily used in high-level programming languages to devise algorithms and obtain structured control flow. These structuring building blocks may also be instrumental for describing real-life systems in analysis and design methodologies at any complexity level. While composition and branching are incorporated into most p...
