Intranet can be grouped into different general categories:

	Internal communication : Creating an involved and effective communication system by making information accessible to organizational members.
	Collaborative/cooperative work : Exploiting web technology to create team oriented work environments that are more productive, higher quality and enjoyable. The virtual private network or the intranet extranet development ensures ease in the flow of communication within an organization or between all branches of an organization.
	Knowledge management : The intranet solution help in facilitating an environment where knowledge is shared and exploited by any group or division in an organization (e.g., best practices database, knowledge net). This involves the process of capturing and leveraging a company's intellectual capital, the most valuable asset of contemporary companies.
	Process redesign : Transforming and disintermediating inefficient practices and processes inside the organization, from supply chain management to internal procurement to expense reports and daily report management of mission critical processes. This would help making paperless office management and office integration more effective.
	Collaboration, best practice and expertise sharing : Structured databases for sharing and transferring individual knowledge to all employees.
