My professional life

With over 30 years of experience in IT, digital transformation, enterprise architecture and organizational change, my profession is acting as thought-leader and practitioner in the intersection of business, technology and people. My Mindset and philospohie is built on the conviction that sustainable business success arises from a context-sensitive interplay between technology and organization.
With the rapid evolution of digitalization and artificial intelligence, this balance becomes increasingly vital as technology and organizational design must continuously co-evolve to create real value.
In the near future, IT, digitalization, and artificial intelligence will become decisive factors for success in every organization. Regardless of the industry or size — whether a local carpenter, a village bakery, or a global bank — every company will, in essence, be a digital company. The ability to leverage technology intelligently will define competitiveness, resilience, and long-term sustainability.
My Core Competences
- Digital Transformation & Artificial Intelligence Enablement: I support clients leverage digitalization, emerging technologies (including AI) as part of broader organizational evolution; from digital readiness to embedding new work-models, data-driven decision-making and agile innovation.
- Portfolio and Product Management at Scale: My work emphasises generating value für customer and clients by setting focus in strategy execution. Means are optimizing prioritization, minimizing cost-of-delay, establishing lean-portfolio practices and product thinking to shift from projects to product and value-streams.
- Business & Systems Architecture: Business architecture is not merely a technical discipline. As business enabler I strive aligning business with technology and organization.
- Enterprise Agility & Lean Organisation: Transforming organizations into value-stream-oriented, empowered systems that move toward dynamic, decentralized decision-making and flow-based delivery is an essential success factor in fast moving and dynamic markets.
- Teaching, Community Leadership & Certification: with my engagement in higher education, community networks and professional bodies (for example founding member and part of the board of directors of the International Requirements Engineering Board IREB e.V.) I care for the future of the profession.
My Career Highlights
- (2018 – today) As founder, partner and executive director of Smart System Guild together with my colleagues we support clients in Switzerland and beyond adapting to complexity, change and digital disruption.
- At Digitec Galaxus AG (2015–2018), I was responsible as Head Business Development for the business and technology development including the organizational transformation from the executive level through the shop-floor.
- At Zühlke Engineering AG (2010–2014), I held senior executive roles as Director Business Development, Distinguished Engineer & Partner driving innovation, scaled agility, product/portfolio management and international consulting presence.
- Since 20 years I am engaged as lecturer and course designer at several Swiss universities (HWZ, HSLU, HSG) focusing on digital readiness, business agility, requirements engineering and digital campaign management.
Digital & AI-Focus
In recent years, my work has strengthened its focus on how AI and data-driven methods as integral part in digitalization and transformation. Examples of my engagement are:
- Reviewer of the IREB certification module “AI-supported Requirements Engineering.” It explains how Artificial Intelligence can enhance the elicitation, documentation, validation, and management of requirements. The guide emphasizes responsible and transparent use of AI, outlines key technologies, prompting techniques, and risks ensuring quality, compliance, and value in AI-enabled analysis processes.
- Development of the higher education “Transformation Process in Marketing Organizations” which explicitly covered AI tools (e.g., for prompt engineering) and automation of manual tasks to meet speed, autonomy and iteration in digital marketing contexts.
My Value Proposition
In respect of current and future application of digitalization and AI, I strive to establish strategic insights and architectural rigour and pragmatic execution. I help organizations:
- translate their digital and AI aspirations into concrete capability roadmaps and value streams.
- shift from project-centric to product-centric thinking and lean portfolio governance.
- design systems and organizations that respond rapidly to market changes and complexity.
- embed culture, leadership and new ways of working that sustain continuous improvement and innovation.
My Personal Style & Engagement
I am convinced that mastering digitalization and technology is an essential capability for every organization.
Yet true success emerges only when we bring people along on this journey: empowering to understand, shape, and thrive within the need of technological change.
I believe in developing organizations where people and technology are treated as equal partners, creating an environment that balances human potential with digital capability to achieve lasting impact and sustainable growth.

My private life




For sure I have a private life.
My kids are grown and left home since years. So I love to be sportive with Petra, biking on any type of bike, occasionally wind surfing, rock climbing or reading the latest novels by T.C. Boyle and Haruki Murakami. And yes, beside that I play a Gibson Les Paul anniversary edition and it might get loud if we turn on the amplifier playing old R&B in a hobby band.
