The high-tech equipment industry is adopting approaches like Model-Based Systems Engineering (MBSE) and Scaled Agile Framework (SAFe) to improve their practices. Instantiations of these approaches do not necessarily align across disciplines. Given the importance of software aspects in systems, the interplay between software and other engineering disciplines should be carefully addressed.

With software permeating our world, modern software systems grow both in size (e.g., lines of code, number of software artefacts) and complexity. Logs produced by software systems during execution are regularly the first and only information used by software engineers to comprehend the behaviour of these complex systems and to repair software faults.

Performance is a key system level property. Performance, too, is affected by the myriad of decisions and choices in the development and configuration of both hardware and software components. This tutorial focuses on measuring and modeling system performance. We will discuss computer hardware architectures and execution architectures, the sofware design concepts for the dynamic behavior of the system.

When designing a system, one would like to have early information on how well a system design addresses stakeholder needs and concerns. Design Space Exploration (DSE) involves exploring the design space for system design candidates, including variants of specific system design aspects. For this, quantitative information on various system aspects is desired.

In this report, we summarize a selection of articles from the state-of-the-art in the domain of environmental sustainability and circularity (ESC). In particular, we focus on (1) frameworks connecting business goals and system architect’s technical decisions and (2) design principles for product design.

Digital services - applications that often span the entire computing continuum - have become an essential part of our daily lives, but they can have a significant energy cost, raising sustainability concerns. The computing continuum features multiple distributed layers (edge, fog, and cloud) with specific computing infrastructure and scheduling decisions at each layer, which impact the overall quality of service and energy consumption of digital services.

The complexity of delivering business value is increasing technically and socially. The increasing complexity triggers the need for an increase in systems competence in several roles within the technical domain. One of the core disciplines to focus on this competence is systems engineering, which gets increasing attention within the Dutch ecosystem to enhance individuals and organizations further in this competence.
