The Synergistic Impact of Integrated Agile and deveops on Software Delivery Performance: An Evidence-Based Synthesis of Velocity, Quality, and Organizational Scaling

الملخص

The domain of software project management is confronting escalating challenges in adapting to rapidly evolving market demands while ensuring the delivery of high-quality products. In this context, Agile and DevOps methodologies have emerged as pivotal frameworks for accelerating software development and enhancing product quality through fostered collaboration and the seamless integration of development and operations processes. This study provides a rigorous, evidence-based synthesis of the demonstrable impact of integrated Agile and DevOps practices on quantifiable software delivery performance metrics. Adopting a Systematic Literature Review (SLR) protocol, this paper rigorously aggregates and synthesizes empirical studies to validate the causal links between methodology adoption and high-performance outcomes across the four dimensions of the DORA (DevOps Research and Assessment) framework. The findings confirm that the synergy between Agile and DevOps leads to the simultaneous optimization of development velocity (high Deployment Frequency and reduced Lead Time for Changes) and system stability (low Change Failure Rate and reduced Mean Time to Recovery).Furthermore, the analysis reveals that successful, large-scale adoption is critically dependent on addressing cultural constraints, fostering psychological safety, integrating security via DevSecOps, and strategically choosing scaling frameworks such as SAFe or LeSS. The core conclusion is that technical rigor alone is insufficient; sustained elite performance requires a holistic transformation that balances technological advancement with profound organizational and cultural change.
