Hassan Faculty of Commerce, Kafr El Sheikh University, Egypt Sustainable business transformation is usually described as a technology problem, a leadership problem, or a human-resource problem. In practice, it is all three. This paper develops a cross-country analytical model that links workforce capability, responsible digital leadership, and sustainable operating capacity into a single diagnostic framework. A curated public-indicator extract was prepared from World Bank World Development Indicators, Worldwide Governance Indicators, and labour-market indicator definitions, covering 41 economies with recent values for internet use, R&D intensity, advanced workforce capacity, female senior management, renewable-energy reliance, carbon pressure, governance effectiveness, and digital s kills. The proposed Workforce Sustainable Technology Leadership Index (WSTLI) is used to compare countries, identify capability gaps, cluster transformation profiles, and simulate the effect of combined upskilling, leadership governance, and green technology interventions. The analysis shows that digital readiness alone is insufficient; several economies with high connectivity still show weak sustainability operating capacity, while others with stronger renewable-energy profiles lack the digital-HR capability needed to convert sustainability into scalable business practice. The paper provides a practical measurement architecture for HR leaders, executives, and policy-oriented business analysts who need to align workforce strategy with technology-enabled sustainability. 2026 29 37 4365 https://creativecommons.org/licenses/by/4.0/ 10.54216/JSDGT.060204 https://americaspg.com/journal/38/article/4365 https://americaspg.com/storage/articles/manuscripts/01M0RTEWKD52NYSG2F7FBVY72E.pdf
