The Human Side of Modularity: Communicating Complexity with Clarity | Pedro Campos at PTH Conf 2025

In today’s fast-evolving technological landscape, modularity has become the cornerstone of innovation—not only in software but across a wide spectrum of engineering disciplines, including hardware. Modularity allows teams to break down complex systems into manageable, interchangeable parts, fostering agility, scalability, and collaboration. But modularity alone isn’t enough. The true power of modular development lies in engineers’ ability to communicate effectively across multiple levels of complexity—bridging the gap between high-level concepts and intricate technical details.

This talk explores how mastering communication at different layers of complexity is not just a “nice-to-have” skill but a crucial competency for modern engineers. Whether you’re working within a modular software team or in hardware divisions such as automotive, success hinges on tailoring your message to diverse audiences—from fellow engineers and project managers to stakeholders with varying degrees of technical knowledge and attention spans. Navigating this spectrum of engagement requires adaptability, empathy, and clarity.

Drawing on real-world examples from Bosch’s approach to product development, with a particular focus on modularity in one of its Business Units, I will share insights into how modular structures shape not only the architecture of products but also the dynamics of team communication. The talk highlights practical strategies to help engineers refine their communication skills, enabling them to convey complex ideas clearly and efficiently, no matter the audience or context.

Ultimately, this presentation will inspire engineers to embrace communication as an integral part of modular development—a skill that unlocks collaboration, innovation, and greater impact. Modularity isn’t just about systems; it’s about people. And in a world where technology grows ever more complex, the ability to translate complexity into understanding will define the engineers and organizations that thrive.
