once.<\/li>\n<li><strong>Ambiguous problem ownership:<\/strong> issues may appear as \u201cnetwork\u201d but originate in application, OS, or cloud service behavior (and vice

without sacrificing quality.<\/li>\n<li><strong>Legacy complexity:<\/strong> inherited configs, inconsistent naming, undocumented circuits, and drift.<\/li>\n<\/ul>\n\n\n\n<h3

inconsistent tooling.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Common reasons for underperformance<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Weak fundamentals leading to

plans.<\/li>\n<li>Avoidance of automation and repeated manual work that increases error rates.<\/li>\n<li>Lack of stakeholder management (missed expectations on delivery timelines or risk
