Question: How important a role are product-service systems playing in CLAAS’s product portfolio now?
Korthals: That depends on what you mean by a product-service system. If you mean supplementary services such as predictive maintenance as part of the after sales service or features such as software updates over the air, it is an area of growing importance for us and represents a major challenge.
Question: What new requirements arise from this with regard to product development?
Korthals: In particular, we have to take solution-neutral customer requirements as a basis for integrating software development, balancing processes and methods from the very beginning. Which is why model-based systems engineering (MBSE) is a very important topic for us. In addition, seemingly mundane topics such as the quality of master data, which we have been working on ever since the advent of PDM, are enjoying something of a renaissance. Even the topic of the end-to-end use of 3D, which is not in itself new, is taking on a new dimension. Suddenly, we find ourselves collaborating with game vendors like GIANTS, who use our 3D models for their farm simulators and in return provide us with rendered models for our sales activities. The coronavirus pandemic in particular has increased demand for virtual sales meetings and training sessions with customers, for example, where we use animated renderings to show them how to get into the cab.
Question: What does this mean for your digitalization strategy? Where are the key fields of activity?
Korthals: There are a number of pillars to our digitalization strategy: modeling and connecting with MBSE, visualization, i.e. the issue of digital continuity with a focus on 3D, and validation using simulations, which is an aspect that should not be overlooked in the wider discussion about digital transformation. In other words, the basic topics remain the same as they were ten years ago. What has changed is the way in which these topics and, indeed, the data models are interlinked. I can map these connections using MBSE, but I also need the link to the tasks in project management or to the configuration for production. Which brings us on to the issue of traceability.
Question: Is traceability driven more by the complexity of product development or the legal burden of proof?
Korthals: Traceability remains important in the context of functional safety, but with regard to the product service systems already mentioned or to autonomous systems, mastery of the technical, process-related and organizational complexity is becoming increasingly important. You can’t negate the complexity. Instead, you have to make it manageable. For this, we need MBSE and configuration management throughout the lifecycle in order to make the interrelationships easier to understand.
