Markus Boll

Senior Advisor & Interim Manager - PMI & PMO Management & Business Transformation (ex Corp. Head of PMI)

Pfäffikon, Switzerland


I am a strategic projects director and an expert in program/project management, deeply committed to driving high-visibility business transformations, performance improvement initiatives, and growth strategies within the industrial (high-tech) manufacturing and energy sectors. I specialize in M&A post-merger integrations, enterprise-wide ERP transformations, and innovation-driven digital transformations. My educational background in Industrial Engineering from KIT, complemented by a recent Executive MBA from HSG, and robust top-management consulting experience from Siemens Management Consulting, uniquely equip me to tackle complex business challenges that demand a highly interdisciplinary and cross-functional approach. Alongside strategic, process, technology, and organizational considerations, I place a strong emphasis on leadership and the human aspects of change management, ensuring that the people involved are aligned and engaged. My experience leading international projects across Europe, MENA, Asia, and the Americas has honed my cultural sensitivity, enabling me to effectively navigate global settings and tailor my leadership style to diverse cultural nuances. This expertise enables me to deliver substantial business value and high-impact results along the core value streams of a company, consistently working across organizational boundaries. My career is marked by a narrative of transformational project leadership across Strategy, M&A, Business Development, Sales, Operations, Technology, and IT. I am proud of my track record of over 25 successfully executed projects, ranging from large corporates to nimble startups. I have supported more than 50 due diligences (focusing on commercial & operational aspects), led over 15 post-merger integrations (deal sizes ranging from €5 million at Oerlikon to €1 billion at Siemens), and played a pivotal role in the strategic formation of the Ionity eMobility joint venture. My approach not only provides strategic oversight but also involves a hands-on commitment to operational excellence and achieving tangible outcomes.
