ProcPy - the Python Message Based Modeler
-----------------------------------------

-   Easy to use

-   Pure Python

-   Define your workflows simply by graphics editor

-   Overview by graphic representation

-   Forecast: how much resources (tie and effort) will have to be used

-   Simple interaction model by E-mail


1. What is ProcPy
-----------------

a) ProcPy - the Modeler
=======================

ProcPy is a Modeler --- that means, it is able to describe
Business Processes. This is easy to be done, by drawing a simple
graphics: the Process Image.

[picture 1]

Use a common graphics editor for doing so. In this Tutorial
we use as an example the famous editor yEd. But any other
editor which gives output from graphml/gml can be used.

1. Installation
---------------

Install Python 2.7 from www.python.org.
Add C:\Python27 to the path (Systemeinstellungen -\> Umgebungsvariablen)
Copy the files in C:\Python27\Scripts to C:\Python27
Create directory C:\Python27\Lib\procpy
Copy the content of the procpy.zip into C:\Python27\Lib\procpy
Copy the files scripts\o* to C:\Python27
Install JAVA 7
Put yed.jar from www.ift-intern.de/ift-intern-tools/11\_yed/yed.jar onto your Desktop.


2. Create your own Business Process
-----------------------------------

-   Use rectangle blocks and arrows between them

-   Edit block label by setting variables:

    $EFFORT = <number>   $TIME = <number>

Also ordinary python code can be used.

-   Labeling of the arrows for branch choosig can be used additionally:

    a)  as an ordinary python condition statement (e.g.: \$TEMP \> 40)

    b)  as a percentage statement (e.g.: 20 %)

-   Be aware that you have one unique block which is no target of any
    other block. This block will be the starting block of the Business
    Procoess Model

Store that .gml-File in a certain directory.

=============================================================

3. The ProcPy Evaluator
-----------------------

Check your Business Process Model by a forecast --- with the ProcPy
Evaluator:

-   Start a console and go to the folder with your .gml-file

-   Under Windows: set PYTHONPATH=.

-   Start it in the directory where you have the .gml-File of your
    process

-   Run: oap g <business_process_file>.gml

The <business_process_file>.gml then will be transformed to a
ProcPy-Python module <business_process_file>.py

The ProcPy Evaluator shows a sketch of the Business Process Model.

You can run forecasts and speed up the velocity.

If you change the .gml-file on the fly, the process sketch in the
evaluator will also change on the fly. Hence, you can work with yEd and
ProcPy Evaluator in parallel.

=============================================================

4. Implement the Business Process Model
---------------------------------------

By the use of the ProcPy Evaluator your Business Process Model in
.gml-Format is converted to a ProcPy-Python-Module with the ending .py
(It can be also manually transformed into a Procpy-Python-Module with:
oap y <file>.gml )

Start a Business-Process with:

    oap <file> run

Continue it with:

    oap <file>.<nr> continue   where <nr> is the number of the continued process

Automatic continuation:

oap x
