Developers may design a new software product or feature without realizing the difficulties ahead, in which case it is better to modify the design rather than insist on a design that does not take into account any newly discovered constraints, requirements, or problems. As a result, there is no guarantee that the requirements the organization has in mind will actually work.","og_url":"https:\/\/www.cybermedian.com\/fa\/what-is-the-problems-of-waterfall-model\/","og_site_name":"\u0631\u0633\u0627\u0646\u0647 \u0633\u0627\u06cc\u0628\u0631\u06cc","article_published_time":"2022-01-25T10:30:49+00:00","article_modified_time":"2025-02-19T02:33:45+00:00","og_image":[{"url":"https:\/\/www.visual-paradigm.com\/servlet\/editor-content\/scrum\/scrum-vs-waterfall-vs-agile-vs-lean-vs-\/sites\/7\/2018\/12\/waterfall-approach.png","type":"","width":"","height":""}],"author":"vpadmin","twitter_card":"summary_large_image","twitter_image":"https:\/\/www.visual-paradigm.com\/servlet\/editor-content\/scrum\/scrum-vs-waterfall-vs-agile-vs-lean-vs-\/sites\/7\/2018\/12\/waterfall-approach.png","twitter_creator":"@vpadmin","twitter_misc":{"\u0646\u0648\u0634\u062a\u0647\u200c\u0634\u062f\u0647 \u0628\u062f\u0633\u062a":"vpadmin"},"schema":{"@context":"https:\/\/schema.org","@graph":[{"@type":"Article","@id":"https:\/\/www.cybermedian.com\/fa\/what-is-the-problems-of-waterfall-model\/#article","isPartOf":{"@id":"https:\/\/www.cybermedian.com\/fa\/what-is-the-problems-of-waterfall-model\/"},"author":{"name":"vpadmin","@id":"https:\/\/www.cybermedian.com\/fa\/#\/schema\/person\/0122cdf8fc3b73482dd8a30c8500f75a"},"headline":"\u0645\u0634\u06a9\u0644\u0627\u062a \u0645\u062f\u0644 \u0622\u0628\u0634\u0627\u0631\u06cc \u0686\u06cc\u0633\u062a\u061f","datePublished":"2022-01-25T10:30:49+00:00","dateModified":"2025-02-19T02:33:45+00:00","mainEntityOfPage":{"@id":"https:\/\/www.cybermedian.com\/fa\/what-is-the-problems-of-waterfall-model\/"},"wordCount":3,"commentCount":0,"image":{"@id":"https:\/\/www.cybermedian.com\/fa\/what-is-the-problems-of-waterfall-model\/#primaryimage"},"thumbnailUrl":"https:\/\/www.visual-paradigm.com\/servlet\/editor-content\/scrum\/scrum-vs-waterfall-vs-agile-vs-lean-vs-\/sites\/7\/2018\/12\/waterfall-approach.png","keywords":["cn-done","es-done","ja-done","tw-done"],"articleSection":["Software Engineering"],"inLanguage":"fa-IR","potentialAction":[{"@type":"CommentAction","name":"Comment","target":["https:\/\/www.cybermedian.com\/fa\/what-is-the-problems-of-waterfall-model\/#respond"]}]},{"@type":"WebPage","@id":"https:\/\/www.cybermedian.com\/fa\/what-is-the-problems-of-waterfall-model\/","url":"https:\/\/www.cybermedian.com\/fa\/what-is-the-problems-of-waterfall-model\/","name":"\u0645\u0634\u06a9\u0644\u0627\u062a \u0645\u062f\u0644 \u0622\u0628\u0634\u0627\u0631\u06cc \u0686\u06cc\u0633\u062a\u061f -
