A Conceptual KPI-Driven Decision and Optimization Framework for IT Service Delivery, Portfolio Performance, and Adoption

Effective management of enterprise IT services requires a structured, data-driven approach to monitor performance, optimize operations, and support strategic decision-making. This study presents a conceptual KPI-driven Decision and Optimization Framework designed to enhance IT service delivery, portfolio performance, and user adoption across complex enterprise environments. The framework integrates key performance indicators (KPIs) at multiple organizational levels including service, application, and portfolio domains to provide actionable insights for operational, tactical, and strategic decision-making. By linking performance metrics with decision workflows, the model enables organizations to identify service inefficiencies, prioritize investments, and align IT initiatives with business objectives. The framework is structured around a layered approach that incorporates real-time monitoring, predictive analytics, and decision-support mechanisms. Service-level KPIs track availability, response times, incident resolution, and user satisfaction, supporting continuous operational improvement. Portfolio-level metrics evaluate resource utilization, cost efficiency, risk exposure, and alignment with strategic priorities, facilitating informed investment and optimization decisions. Adoption metrics measure usage trends, engagement levels, and feature utilization, providing visibility into organizational acceptance and the effectiveness of change management initiatives. By embedding KPI-driven insights into structured decision-making processes, the framework enables dynamic optimization of IT operations, balancing performance, risk, and cost considerations. The model also supports scenario analysis, forecasting, and what-if simulations, allowing IT leaders to evaluate potential interventions and resource allocations before implementation. Furthermore, the framework emphasizes continuous feedback loops, integrating lessons learned, incident reviews, and evolving user behavior to refine KPIs and decision criteria over time. This conceptual framework contributes to the literature on IT service management, portfolio optimization, and digital transformation by providing a structured, data-centric methodology for measuring, monitoring, and enhancing IT performance. It offers practical guidance for enterprise architects, IT leaders, and operations managers seeking to maximize service quality, portfolio value, and adoption outcomes in complex and rapidly evolving IT environments.
