Role of DevOps in the Lifecycle of Software Development in the context of Bangladesh

Abstract

DevOps (Development and Operations team) is a foundational approach in the recent software engineering scene, integrating it to improve collaboration, automation, and continuous delivery. Its adoption varies across countries with different organizational cultures, resources, and technological infrastructures. In Bangladesh, where the software industry is expanding rapidly along with new technologies, DevOps integration plays a key role. However, there is limited empirical research examining DevOps' role in the Software Development Lifecycle (SDLC). This study addresses this gap by conducting a unified, multi-dimensional investigation across three domains: Critical Success Factors (CSFs), DevOps Capability Maturity (CMMI), and Security integration within DevOps practices (DevSecOps). Data were collected from around 79 professionals, using structured questionnaires derived from global frameworks and models. CSF analysis used a Multiple Linear Regression (MLR) statistical model to quantify the relative association of 19 CSFs with perceived project success, revealing from the exploratory sample that automation-related practices and intra-organizational collaboration showed the largest estimated effect sizes. The maturity assessment used reliability analysis, correlation analysis, and K-means (K = 3) clustering, showing variation across CMMI capabilities: Monitoring and Continuous Development showed higher maturity. Security integration was evaluated using non-parametric methods, including Spearman Rank Correlation, permutation tests, and FDR correction, which demonstrated that security is most effectively integrated at build and pipeline stages. These emphasize the interrelationship between automation, culture, maturity, and security as determinants of DevOps effectiveness in Bangladesh. The study proposes a refined CSF model, a maturity model, and security practices evaluation. The models are tailored according to Bangladesh’s software firm needs.
