Yun Consultancy contributes to the category definition and structuring of the coordination-layer sustainability implementation architecture: the Sustainability Implementation Infrastructure Layer (SIIL), 2026.
Together with sector deployment frameworks such as the Tourism Sustainability Systems Framework (TSSF) and implementation interface environments such as SiApp, this architecture stack supports the transition from sustainability commitments toward coordinated operational rollout across sectors and institutions.
The SIIL diagnostic classification instrument methodology provides the first cross-sector method for locating coordination-layer implementation conditions within sustainability transition environments.
