ASQF Certified Professional for IoT
ASQF · Working Group Member · 2017–2019
The ASQF Certified Professional for IoT (CPIoT) is a training scheme with certificate, developed by an ASQF working group, that focuses on quality engineering for the Internet of Things. It covers quality characteristics and standards, IoT architecture, processes and methods, testing and the life cycle of IoT solutions, and includes a glossary.
ISTQB Test Automation Engineer Syllabus
ISTQB · Initiator and Author · 2013–2016
The ISTQB Certified Tester Advanced Level syllabus Test Automation Engineer defines the learning objectives for engineers who design, develop and maintain test automation solutions, including the generic test automation architecture, deployment, reporting and metrics, and the transition from manual to automated testing. It is the basis of the corresponding international certification.

VHPready
VHPready Forum · Co-Initiator · 2014–2016
VHPready (Virtual Heat and Power Ready) is an open industry standard for communication with, and control of, decentralised power generation plants, consumers and energy storage systems from the central control system of a virtual power plant. It builds on the established protocols IEC 60870-5-104 and IEC 61850-7-420. Originally developed by Vattenfall, it has been maintained by the Industrieforum VHPready e.V. since 2014.
TTCN-3 Certificate
German Testing Board (GTB) · Author · 2006–2010
The TTCN-3 Certificate is a certification scheme for testers working with TTCN-3. Its curriculum defines the learning objectives, from the basics and language features of TTCN-3 to test execution, test design and development, extension packages and tool support.
UML Testing Profile (UTP)
OMG · Initiator · 2001–2006
UTP is a standardised UML-based language for designing, visualising, specifying, analysing, constructing and documenting test artefacts, in particular for model-based testing. Version 1.0 was adopted in 2005; the current line is UTP 2.
Testing and Test Control Notation (TTCN-3)
ETSI · Rapporteur · 1998–2014
TTCN-3 is a standardised language for specifying and executing tests of reactive and communicating systems, for example protocol, service, module and API tests. It is published by ETSI as the multi-part standard ES 201 873.
Rapporteur for:
- ES 201 873-1: TTCN-3 Core Language
- ES 201 873-3: TTCN-3 Graphical presentation Format (GFT)
- ES 201 873-5: TTCN-3 Runtime Interface (TRI)
- ES 201 873-6: TTCN-3 Control Interface (TCI)
- ES 201 873-9: Using XML schema with TTCN-3
Contributions to:
Message Sequence Chart (MSC)
ITU-T · Associate Rapporteur · 1998–2004
MSC is a graphical and textual language for describing how system components and their environment interact by exchanging messages. MSCs are used for requirements specification, test case specification and documentation of real-time and telecommunication systems, often together with SDL.
ATM Test Suites
ATM Forum · Working Group Member · 1995–1998
The ATM Forum test specifications are abstract test suites for conformance and interoperability testing of Asynchronous Transfer Mode (ATM) equipment, for example for the ATM layer, the ATM Adaptation Layer 5 and SSCOP. They follow the ISO/IEC 9646 conformance testing methodology and are written in TTCN. The specifications are now hosted by the Broadband Forum.
