<p>Technology development is a resource-intensive activity incorporating substantial investments in money, manpower, time, and research facilities. However, if developed technologies fail to commercialize, these efforts risk becoming futile. To address this concern, the present study proposes an integrated technology impact assessment (TIA) framework using a comprehensive set of key performance indicators (KPIs) and associated sub-KPIs. Further, the present study illustrates the usage of the integrated framework in the field of environmental technology. An extensive literature review identified ten thematic KPIs encompassing research and development, market prospects, environment, economic, societal, regulatory considerations, etc., and 36 sub-KPIs, leading to 51 critical considerations for measuring the impact of technology outcomes. The framework was illustrated through a case application within a public-sector research organization, where an expert panel identified 23 organization-relevant considerations from the master list. Further, the selected technology was rated on a 5-point Likert scale, and the aggregated inputs were processed using Grey Relational Analysis (GRA) to derive a composite Technology Impact Index. This methodology offers a replicable model for systematic technology assessment, enabling decision-makers to align developmental efforts with broader sectoral and societal goals.</p> Graphical abstract <p>Framework for technology impact assessment</p>
