  • Feature Comparison Among Workflow Engines (Part 1)

    Feature Comparison Among

    Workflow Engines



    In this post I compare workflow engines base on factors which are important in every process-driven application.

    Factors that I considered are as below :

    1.Support of workflow architectures : State Machine, Sequential, Flowchart

    2.Event-driven built-in framework for alerts
            (with this feature we can have event raised by reaching a threshold like getting out of stocks in repository and
              associate workflow with events.)

    3.Security handling of pause, Hold, ... states

    5.Parallel activities (fork / join)

    6.Work tracking and logging (Activity and Event)

    7.Building custom activities

    8.Graphical workflow designer

    9.Runtime workflow alteration
            (Like changing an IF condition based on runtime)

    10.Database they support natively

    11.Interoperability and Integration with other systems
            (Like share point, Biztalk server, WCF, MSMQ)

    12.Other systematic prerequisites
            (Like specific version of .net framework)

    13.Performance under heavy load

    14.Central exception handling

    15.Developer company future support
            (For releasing service packs and new features)

    16.Staff training complexity

    17.Interaction Languages
            (Is there any intermediary language for communication with workflow?)

    18.Design workflow in Code, Designer and ...

    In the blow table I will compare four famous products in workflow industry .
