Interview with Johannes Lenßen, Senior Manager in the System Landscape Transformation practice
The System Landscape Transformation (SLT) practice team guides large organizations through complex transformation programs, from the initial concept to final implementation. But what does the work actually look like in this environment? And how does a career develop in a field focused on the interrelationships between data, processes, and system landscapes? We spoke about this with Johannes Lenßen. He has been part of the SLT team at cbs for ten years and currently serves as a Senior Manager.
Johannes, how did you originally get into the SLT field?
I studied industrial engineering and subsequently started working at a small IT consultancy. That’s where I gained my first experience with SAP, databases, SQL, and analytics.
However, I hadn’t had any exposure to data migrations back then. Even so, my profile was a great fit for the SLT field. Many of the things that engaged me back then — analyzing data, understanding interrelationships, solving technical problems — still play a major role in my work today. I was particularly drawn to the combination of project-based work, technical depth, and large-scale transformation initiatives. That is exactly why I joined cbs.
You are a Senior Manager today. How has your role evolved over the years?
I started as a consultant and took on project responsibility early on. Over the years, additional tasks were added — ranging from architecture and design issues to team leadership and mentoring. At the same time, I still work closely with the projects today. The exciting thing is that the role is constantly evolving.
What makes working in the SLT field special for you?
For me, it is primarily the combination of variety and a holistic approach. No two projects are alike. Whether it’s an S/4HANA transformation, a carve-out, a harmonization effort, or a cloud project, every starting situation brings its own unique challenges. Naturally, our focus in these projects is on data, processes, and applications. However, it is important not to think in terms of isolated SAP functionalities, but rather to keep dependencies, interfaces, interrelationships between systems, and the entire system landscape in view.
Over time, you develop a very broad understanding of transformations. You learn how data, processes, technology, infrastructure, and organizational changes interact. It is precisely this mix of technical depth, diverse projects, and a focus on the big picture that makes the work so exciting for me.
Who do you work with on projects like these?
The range is broad. On the client side, you work with business departments, IT teams, project managers, and management stakeholders. Internally, you coordinate with colleagues from various specialist areas. This allows you to gain insight into many different perspectives and broaden your horizons well beyond specific subject areas.
What skills are particularly important for success in this environment?
Analytical thinking and a strong grasp of logic are essential. Many issues in the SLT environment resemble complex puzzles: you analyze interrelationships, develop solutions, and verify that everything fits together seamlessly.
However, communication, personal accountability, and a willingness to take active responsibility are just as important. To drive projects forward successfully, you need to address issues transparently, share information, and collaborate effectively with a wide range of people.
You now support colleagues in their own professional development. What does that look like in practice?
Mentoring is a key part of my role. For instance, when colleagues take on their first project management responsibilities, I support them from the background as a sounding board. We regularly discuss challenges, client requirements, or project situations and jointly consider the best next steps. At the same time, it is important that the colleagues themselves remain visible and take ownership. My goal is not to take tasks off their hands, but to foster their development. Incidentally, this is exactly the kind of culture I have experienced at cbs for many years. People are given opportunities to take on responsibility and grow through their tasks. At the same time, there are always experienced colleagues on hand to provide support whenever it is needed.
You have been part of the SLT team for ten years now. What is it about your work that still excites you today?
Even after ten years, no two days are alike. The work remains diverse and varied because projects, clients, and challenges are constantly changing. At the same time, cbs has always given me the opportunity to grow professionally and take on new areas of responsibility.
For me, this is an environment that fosters long-term growth. Professional development isn’t just talked about — it is actively encouraged. If you show interest, want to take on responsibility, and are open to new topics, you get the chance to shape your own career path.
What advice would you give someone considering a move to the SLT team?
If you want to understand how companies and SAP landscapes really work, the SLT area is the perfect place for you. You should be eager to delve into complex issues and look beyond your own immediate area of expertise. Doing so opens up a unique consulting environment with plenty of opportunities for professional growth.
