Shoal to present at SETE 2026
Shoal Group is pleased to announce that two presentations have been accepted for SETE 2026, the leading Systems Engineering Test and Evaluation Conference in Australia. Under the theme “Adding ‘superpowers’ to systems engineering”, Shoal’s presentations demonstrate Shoal’s own superpower – applying advanced systems thinking to complex, multi stakeholder challenges.
The first presentation is co-authored by Tommie Liddy, Turen Pty Ltd, and Matthew Wylie, Head of Engineering at Shoal. Titled ‘A usage first modelling methodology in SysML v2’, the presentation explores the strengths and limitations of usage-first modelling in SysML v2. Using a case example, they demonstrate how modelling, using primarily usage elements, can (and in some cases, cannot) efficiently express operational scenarios, system behaviour, system structure and connectivity. The study highlights contexts where usage-first modelling provides clarity and agility, such as during stakeholder engagement, mission analysis, and trade studies. Conversely, it identifies situations where this approach alone becomes insufficient, necessitating a transition to full usage-definition modelling. Based on their findings, Tommie and Matthew propose a set of criteria to guide practitioners in deciding when usage-first modelling is appropriate and how it can best be applied in SysML v2.
The second presentation is titled ‘A Whole-of-Systems Exploration of Australian Energy Decarbonisation’ and co-authored by Mark Unewisse PhD, Systems Engineering Advisor, Stephen Cook PhD, Senior Principal Systems Engineer, and Matthew Wylie. Together, they apply a holistic systems-of-systems (SoS) approach to consider energy decarbonisation in balance with a range of competing national development goals. In the Australian context, there has been strong public support for climate action, aligning with many other countries pursuing strategies to limit green-house gas emissions and mitigate the effects of climate change. In recent times, there has been increasing cognisance of the consequences of implementing these strategies. In this presentation, the team advocate that greenhouse gas (GHG) reduction efforts need to take a whole-of-systems perspective to ensure a balanced implementation that not only delivers substantial reduction in GHG emissions but also ensures that other key global imperatives are not sacrificed.
Together, these papers showcase Shoal’s strength in applying advanced systems engineering and modelling methods, from the technical detail of SysML v2 to whole-of-nation systems-of-systems analysis. They demonstrate how rigorous, model-based approaches can improve decision making in both engineered systems and major societal challenges.
SETE 2026 will be held in Sydney, from 27 to 30 April. It is the premier conference of the Systems Engineering Society of Australia (SESA) and the Southern Cross Chapter of the International Test and Evaluation Association (ITEA), presented together with the International Council on Systems Engineering (INCOSE) and Simulation Australasia.
