In spite of good coverage of sustainability and sustainable development both in scientific journals and other publications, humanity is on a steady unsustainable track consuming more than is produced. Understanding of change needs, does not seem to convert into sufficient change action. Sustainability issues are often complex, interdependent and hard to comprehend, indicating that sustainable development, in addition to change willingness, requires a holistic perspective. Seeing and understanding systems - systems thinking - is important. This implies that sense-making of systems and of sustainable development is important as a prerequisite for change. Possibilities of realising synergies between quality management and sustainable development are often discussed but do often not seem to be fully realised. This paper tests two system models from Quality Management in the context of sustainability in cement manufacturing and building material production. The indicative results suggest that the proposed system models are able to describe and identify improvement opportunities that could be used to create interest for change.
