Successfully lead challenging transformations with clarity, trust, and renewed momentum
In transformation initiatives, the focus is strongly on strategy, structure, and efficiency. However, the critical role of culture, leadership, collaboration, and communication for success is often underestimated – for mergers, reorganizations, restructurings, as well as for the introduction of AI and new technologies.
When change stalls, it quickly becomes noticeable – in results, in dynamics, and in collaboration. This is precisely where stumbling blocks arise that slow down projects:
- Results fall short of plan
- Teams come under pressure, resistance and conflicts increase
- Customers sense uncertainty
- Frustration spreads and key employees leave the company
I work with you to get your initiatives moving (again) and implement them successfully by jointly:
- Clearly align change and plan with a holistic view
- Empower leaders to guide teams confidently through change
- Strengthen teams in collaboration and impact
- Make tensions and conflicts visible and resolve them constructively
- Develop solutions for specific challenges – even where none are visible today
I work with you both during difficult phases of transformations, and when you want to successfully prepare and professionally implement changes within your transformation initiative from the outset.
"I’ve known and worked with Iris for many years, and she is someone I trust deeply. She brings rare professional maturity, calm authority, and credibility to complex change such as M&A and integration environments.

Iris is not only a strategic thinker - she is someone who genuinely helps leaders and organisations move forward in demanding situations, laying the foundation for successful integration."
“Iris is a safe harbor. With her senior guidance she helped me as a CEO navigate the integration process when we got into a tough situation and helped us find a better way forward.“
“As Azets Ireland, we have had a very positive experience working with Iris during the integration phase of forming the business in 2025. She is an expert in her field, and has a calm assured manner, which creates trust in all of those she engages with. For those reasons, I have no hesitation in recommending her.”
Iris’ extensive experience of acquisitions gives her words and suggestions a great deal of credibility. Iris is a great team player, welcoming different points of view and challenging our ideas with other teams to find the right balance. She managed the project and the team with great flexibility, while instilling the rigor and pace needed to bring the project to a successful conclusion.
I am Iris Martens - Change Expert, Organizational Development Practitioner, and Systemic Coach
with over 25 years of consulting experience - including > 10 years in Mergers & Acquisitions (M&A).
After 28 years of consulting at Accenture – most recently as People Integration Lead for Accenture Acquisitions – I know what transformation means in reality: strategically, organizationally, and humanly.
Today, I combine this experience with a systemic attitude and perspective. I look at numbers, roles, and processes, as well as dynamics, tensions, and unspoken issues. I support organizations in remaining capable of action – or becoming so again – even in complex phases.
Services
Change always begins with and within people. An organization can only successfully transform if structures support the new direction, leadership creates clarity, and teams collaborate effectively and take responsibility.
I work on all three levels – organization, leadership, and team – combining a strategic perspective with concrete collaboration. This creates clarity, trust, and progress – at all levels of the organization. Change is not just planned, but lived and measurably effective.

Organization in Change
Purposefully align structures, processes, and roles. Create identity. Bridge cultural and value differences. Clearly establish communication – so that change is measurably effective.

Team Development
Clarify collaboration and make teams more effective. Build trust and resolve conflicts – so that teams achieve their goals efficiently.

Leadership Development and Coaching
Empower leaders to foster team collaboration and performance and to navigate transformations confidently.
Services intertwine where change becomes complex
In transformation phases and M&A contexts, organizational, team, and leadership development cannot be separated. They influence each other – and only unfold their full impact in interaction.
