Introduction &amp; Overview<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">What is Root Cause Analysis (RCA)?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Root Cause Analysis (RCA)<\/strong> is a systematic process used to identify the fundamental cause(s) of faults, problems, or incidents within systems. Rather than addressing symptoms, RCA focuses on tracing issues to their origin, enabling teams to implement long-term fixes rather than short-term patches.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In the <strong>DevSecOps<\/strong> ecosystem\u2014where Development, Security, and Operations are tightly integrated\u2014RCA plays a pivotal role in minimizing recurring incidents, improving system reliability, and ensuring compliance and security by addressing vulnerabilities at their core.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">History or Background<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Origin<\/strong>: RCA has roots in quality control practices such as <strong>Total Quality Management (TQM)<\/strong> and <strong>Six Sigma<\/strong>.<\/li>\n\n\n\n<li><strong>Evolution<\/strong>:\n<ul class=\"wp-block-list\">\n<li>1940s: Emerged in industrial manufacturing and aviation safety.<\/li>\n\n\n\n<li>1980s\u20132000s: Adopted in IT operations and software incident management.<\/li>\n\n\n\n<li>2010s onward: RCA became vital in <strong>DevOps<\/strong>, <strong>SRE<\/strong>, and <strong>DevSecOps<\/strong> practices for identifying causes of breaches, failures, or misconfigurations.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Why is it Relevant in DevSecOps?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In DevSecOps, frequent releases, automated pipelines, and shared responsibility mean <strong>failures can propagate quickly<\/strong>.
