Holding space for awareness in business, nurturing team engagement, and boosting organizational performance.

With over two decades of experience in corporate companies, I've played a pivotal role in advancing businesses across the End-to-End Supply Chain in FMCG, Pharma, and Medical Devices. My passion lies in Integrated Business Planning (IBP) and driving large-scale cross-functional transformations. Throughout my corporate journey, I've focused on refining processes and systems. However, over time, I've come to realize the paramount importance of people.

Over the last years, I've delved deeply into personal and organizational development, leading to the creation of the holistic HELIBLICK Decision-Making framework. We help leaders to build sustainable organisational structures that will allow the teams to navigate business uncertainty with confidence and clarity.

“Learning is not compulsory.... neither is survival!” – W. Edwards Deming.

Learning and continuous improvement have been the thread in my more than thirty-five years of commitment to Procurement & Supply Chain Management. An area my heart is still beating for. As senior manager / CEO I have been fortunate to lead organizations, teams and individuals in various industries in different geographical and cultural settings. Due to this broad variation, I built-up and honed my ability to have an eye for the overall picture and yet to quickly zoom in to the essentials.

Processes and Tools are important for analysis, predicting, managing, monitoring and improving the business and helping it to achieve its goals. In the end, however, the teams and the individual contributors are the ones who determine the success and especially the durability and the sustainability. In the many changes I have initiated and led over the years, this has turned out to be “the golden nugget” of leadership / management.
