PLE in Action: From Systems Engineering Methods to Scalable Reuse

Oliver Bleisinger leads Model-Based Systems Engineering at :em engineering methods AG, supporting industrial customers in applying Systems Engineering methods to complex development environments. With experience across more than 45 Systems Engineering projects, his work focuses on connecting MBSE, Product Line Engineering, and practical engineering processes to create measurable business value. Oliver also brings a strong research background in AI-supported Systems Engineering, with more than 70 publications and conference contributions across industrial and research forums.

Johannes Krautkremer specializes in Requirements Engineering, Model-Based Systems Engineering, configuration management, and variant management. His background spans the full engineering lifecycle, from system design and implementation to verification and manufacturing across automotive, defense, and medical device environments.​

At :em AG, Johannes supports international customers in implementing Product Line Engineering and Systems Engineering practices across complex product portfolios, helping teams connect methodology with scalable engineering execution.

Kristina Avdejuk is an MBSE consultant with expertise in Systems Engineering, modular product architecture, and product development. She supports customers in introducing and scaling Model-Based Systems Engineering by shaping SE processes, enabling development teams, and applying MBSE methods in complex industrial environments.​

Her work connects Systems Engineering with portfolio, product line, and sustainability perspectives, helping organizations demonstrate the value of modularization and Product Line Engineering through practical use cases.

Rachna Harsh is a Manager in Solutions Engineering at PTC, based in Germany, with expertise in Systems Engineering and Product Line Engineering. She works with organizations to translate complex requirements into scalable engineering solutions that improve reuse, standardization, and efficiency across product portfolios.​

At the roadshow, Rachna will share practical perspectives on how systems thinking, model-based methods, and PLE can help engineering teams manage complexity, accelerate innovation, and move from methodology to sustainable execution.

Shivani Hegde is a Solutions Consultant at PTC with over five years of experience in Product Line Engineering. She works closely with customers to support the adoption of systematic variant management approaches, helping organizations manage complexity and improve product development efficiency.​

At the roadshow, Shivani will bring practical insight into how PLE can support reuse, variability management, and more scalable engineering practices across complex product development environments.

Norbert Siman is a Senior Solution Consultant at PTC, working with leading global companies to design and implement ALM solutions using Codebeamer. He brings strong domain expertise in regulated industries, particularly MedTech, and supports customers in areas such as requirements management, risk processes, and compliance-driven development. In addition to customer engagements, he contributes to technical enablement and solution best practices across the organization.
