1 Introduction

This page will include a description of Business process management notation (BPMN) software and associated Business process management systems.

A Business process modeling lifecycle includes the ability to design, model, execute and monitor business processes. "Business" refers to any kind of environment where humans and machines have to coordinate in some kind of goal-oriented workflow.

2 The BPM development lifecycle

2.1 Overview of the development process

There is a lot of marketing waffle about how easy it is to implement BPMN models. Certainly, using a PBMN software combo can save a lot of time, but the processseems to be neither straight forward nor simple as of December 2012. There is no simple way from a BPMN model to an executable application.

The basic workflow (lifecycle) looks like this:

1) Modeling and simulation'

  • Design / model a process

2) Data configuration, interface configuration and/or integration

This step is technically speaking the most difficult and implies configuring / implementing a lot of various types of "parameters" through various interfaces. E.g. create the user interface or specify the integration with other services. This can be done in many different ways and is vendor specific. Often, it requires programming or at least scripting, but in most current modern system, one can get away with forms generators, data definitions and connectors to other services.

  • Each type of data that participants can input/output has to be modelled in some way. Data can flow from one task to another or just be made available.
  • User interface forms have to be defined for the execution engine that will drive the collaboration
  • A way to manage documents produced must be found (e.g. a WebDav document repository)
  • Interaction with other services must be defined, e.g. email, social software, other enterprise services
  • Business rules can be defined (e.g. when a person has the right to obtain a higher salary for writing wiki contributions)
  • Applications and various middleware can be programmed.
  • Generate the server application(s)

3) Execute and manage

  • Add processes
  • Manage

4) Monitor

  • Track activities and produce reports

Each of these steps require different competences and may be performed by people with very different profiles. E.g. Bonitasoft, in their introductory tutorials, presents a table that distinguishes between the business analyst, the process engineer, the application developer, and the (process) adminstrator and/or end user. In addition, a systems engineer may be needed.

Bonitasoft's vision of BPMN-related skills (slightly modified by DKS)
Profile Subject area Tasks
Business analyst Process design Model a process, define actors, check the model, and more, to create a process diagram (BPMN) for collaboration
Process engineer Process definition Add variables, define conditions on transitions, add connectors, and more, to make a process diagram executable
Application developer Application development Customize web forms, configure page flow, customize look 'n' feel, and more, to customize process web applications
Administrator Process administration Manage processes, cases, steps, users, etc.
End User Use processes and process data Use the system, use monitoring and reporting tools. Also can include process administration.

2.2 Tools

The following figure explains how different Activiti components (a popular BPMN suite) combine to form a complete solution for BPM in the full context of software development. The blue components are part of the Activiti scope. The gray components are out of scope. (Activiti Components, retrieved 14:30, 19 December 2012 (CET))

Activity components (dec 2012)

That kind of picture doesn't really tell what a designer has to do in order to have a working model. It involves a lot of XML parametrization and could even include Java programming. In other words, going from a BPMN drawing to something that is executable is a long route that requires good understanding of data modeling, web services, UI design and so forth.

Most vendors modeling tools include most of the functionality that is needed to create forms and to use connectors. It is not yet clear to us in what ways standards are used, i.e. if exported BPMN 2.0 includes such information at least to some extent...

Let's have a look at the functionality a BPMN design tools may have:

  • A PBMN modeler / drawing tool (all tools have that)
  • ....
  • ....

(soon....)

Let's have a look at a few examples:

2.2.1 Pure modeling tools

There exist various kinds of pure modeling tools:

  • Some only allow to create drawings and to export information files (e.g. a graphic of drawing or a PDF summary of the model)
  • Others may include some type of verification, a bit of configuration, plus export facilities (either in some kind of standard format like BPEL or in some vendor-specific format interacting with their BPMS).

A typical example of simple modeler (a BPMN-compliant drawing tool) is ARIS Express:

Aris Express 2.4

A typical example of a modeler that allows to export a model to a BPMS is the Bizagi Process modeler:

2.2.2 Design tools

Design tools allow to

  • draw BPMN diagrams
  • verify and simulate
  • configure the model in order to make it more executable. Usually this produces some kind of proprietary code that works with a given BPMS.

Typically, such tools require the designer to "annotate" various elements of the model and more ...

3 List of software

There exist several free tools. The commercial versions of the (commercial) free diagramming tools often include an execution engine. Most often is difficult to find out what version of BPMN is supported (BPMN 1.2 or BPMN 2) and what kinds of standards are used for run-time models. Globally speaking, most vendor documentation lacks a simple technical description explaining how a business process model can be implemented. In promotional videos, the tricky steps (defining data models, user interfaces, connectors, etc.) are barely touched...

This list is by no means complete, see also the links sections below for better resources.

3.1 Free modelers

See rather the suites below. Most vendors provide both a modeller and an execution engine plus other middleware.

Only simple drawing

Such tools usually are plugins for diagramming software

  • Oryx, (Signavio) a project to create BPMN 2.0 diagrams, EPCs or Petri nets online. Free for academics.
  • OMII-BPEL, Modelling, monitoring, executing scientific workflows with BPEL. (We did not manage to install this, didn't find any installation instructions either ....)
  • BPMN 1.1 stencils for Visio and OmniGraffle by Frank Puhlmann and Alexander Großkopf.
Libraries that can be embedded
Verified drawing

Such tools are special-purpose BPMN tools that make more or less sure that a drawing is correct.

  • ARIS Express. Closed source freeware for BPMN 2/EPC from Software AG. (Java-based, tested under Ubuntu 10 and Win 7, works - Daniel K. Schneider June 2010/Dec 2012.
Additional functionality like verification, simulation and BPM formats output
  • FreeModeler.com. Free online modeling tool (design, validation, documentation and simulation).
  • Sketchpad BPMN is a tool for drawing and editing BPMN (Business Process Modeling Notation) diagrams. Sketchpad process models are serialized and stored as XPDL 2.1 files. Sketchpad was originally developed by Global 360 as Process Modeler Analyst Edition. (not tested)
  • ADONIS:Community Edition. BPMN 2.0 modeling, verification, simulation, stepper, XPDL export (Windows only, needs SQL server).

3.2 Totally or somewhat free suites

Activiti
  • Activiti BPM Suite, a workflow and Business Process Management (BPM) Platform (authoring tool and execution engine) targeted at business people, developers and system admins. This suite draws from prior experience with jBPMN (see below) and includes several tools, including a modeler and an execution engine.
  • Activity designer (implemented as Eclipse plugin)
  • Activity BPMN 2 process engine implemented in Java. It can run in a Java application
  • See also the commercial alfresco product, the principal sponsor of Activiti.
ARIS

  • The Bonita execution engine
  • Documentation requires to register
Jadex
  • Jadex process. LGPL licence. “The Jadex Processes project provides modelling and execution facilities for workflows.

This is part of a larger project. Jadex is a Belief Desire Intention (BDI) reasoning engine that allows for programming intelligent software agents in XML and Java.
