Katzenbach Executive Consulting started its operational activities on 01.08.2013 and is now celebrating its 10th anniversary.



Ten years of intensive and successful cooperation with more than 50 clients, additionally more than ten advisory-engagements with SME´s and start-up´s in more than ten countries on three continents. 


In all these engagements, the focus was concentrated on the customer’s success rather than on achieving maximum sales. Perhaps that is the foundation for a never expected commercial success.


I was able to get in contact with many people with diverse cultural backgrounds and with different attitudes to think and act. This was awesome and inspiring. 


Projects outside my homefield of automation and transportation industries were exciting. These broadened the horizon and provided completely new insides and experiences. This expanded my field of view. 


The individual projects enable also my opportunity to reflect on my many years of management experience in order to expand my knowledge for future work and consultancy services.


As a result of these activities, three key areas have emerged where people are the focus and the foundation for projects and initiatives success.:

  • Human Change Management
  • Intercultural Cooperation
  • Knowledge Management

This leads me to develop methodical toolboxes for consulting and trainings. Meanwhile these toolboxes are approved and used successfully on the client side.

More you can find on this webside under Seminars and Coaching.


All the knowledge and experiences could also be developed in the interaction with science and teaching. Both areas, consulting and science, complements each other very well and create mutual added value. Very valuable in this area is my active participation with the Scientivic Community for Productdevelopment.


I am looking forward to the next years of dedicated and successful cooperation with my customers and partners.


best regards yours Alfred Katzenbach

Implementations on DIN Spec 91383 (JTIAP V2): results of the fourth survey

  • In March 2019, the fourth worldwide survey on the current activities concerning the implementation of the JT Industrial Application Package Version 2 (DIN Spec 91383)  was carried out. Here are the results in summary:

  • CAD ISV´s:

    • Autotdesk will deploy JTIAP V2 fully for their authoring-tools and integrate it in their ATF-translator
    • DS will support ISO 14306 ed1 as well as  JTIAP V2 by partner solutions
    • PTC uses Siemens JT toolkit for their JT compatible products 
    • Siemens products that create and utilize JT are compatible with JTIAP V2


    • Eleven out of fifteen system-integrators have a complete solution available today
    • Two have parts of the solution available and are engaged in further development
    • Two are waiting for customer request

  • To sum up: 
  • We have reached in a short periode of time an outstandig maturity
  • On the user side we have more than 250 Mio JT files in the databases done by more than 100.000 Users 
  • We have the direct support from nearly all ISV´s
  • We have integration solutions from nearly all relevant systemintegrators
  • So the deployment project of JTIAP V2 and DIN Spec 91383 has completed it´s mission and can be closed. All further activities will be done by prostep ivip JT Workflow and Implementor Forum
