Der Plan ber\u00fccksichtigt auch m\u00f6gliche Hindernisse wie Personalengp\u00e4sse oder Budgetbeschr\u00e4nkungen, die den Projektfortschritt beeintr\u00e4chtigen k\u00f6nnten.<\/p>\n

In dieser Phase wird h\u00e4ufig die Software Development Requirement Specification (SRS) verwendet, um die Projektanforderungen genauer zu definieren.<\/p>\n

#3 \u2013 Design & Architecture<\/strong>\u00a0<\/span><\/em><\/h3>\n

\n

During this phase of product creation, product architects and developers work together to bring the concept into reality. After researching solutions for anticipated issues and risks previously identified in stage 2\u2019s SRS document, several design approaches are documented within a Design Document Specification (DDS). This DDS will provide developers with an essential source during production\u2019s stage 4 as they code based on its content.<\/p>\n

#4 \u2013 Coding & Implementation<\/strong>\u00a0<\/em><\/span><\/h3>\n

\n

In der Implementierungsphase setzen die Entwickler das Design durch Programmierung in ein konkretes Produkt um. Daf\u00fcr m\u00fcssen die Teams mit Programmiersprachen und Frameworks vertraut sein, um sicherzustellen, dass der geschriebene Quellcode alle Projektanforderungen erf\u00fcllt. Dies ist m\u00f6glicherweise die zeitaufw\u00e4ndigste Phase des Softwareentwicklungszyklus (SDLC), daher kann diese Phase ausgelagert werden.
