A CMS (Content Management System) is a software application used to create, manage, and modify digital content.

Content Management System (CMS) is a software application or set of related programs used to create and manage digital content. It is typically used for enterprise content management (ECM) and web content management (WCM). CMSs are often used to run websites containing blogs, news, and shopping. Many corporate and marketing websites use CMSs. CMSs typically aim to avoid the need for hand coding but may support it for specific elements or entire pages. Product Management in a CMS involves managing the product lifecycle from conception to launch, including product planning, development, testing, marketing, and maintenance. Product Managers are responsible for understanding customer needs and developing products that meet those needs. They must also ensure that the product meets all legal requirements and is competitively priced. Product Managers must also be able to effectively communicate with stakeholders such as customers, developers, marketers, salespeople, and other departments within the organization.
