Tizen is an open and flexible operating system built from the ground up to address the needs of all stakeholders of the mobile and connected device ecosystem, including device manufacturers, mobile operators, application developers and independent software vendors (ISVs). Tizen is developed by a community of developers, under open source governance, and is open to all members who wish to participate.
The Tizen operating system comes in multiple profiles to serve different industry requirements. The current Tizen profiles are Tizen IVI (in-vehicle infotainment), Tizen Mobile, Tizen TV, and Tizen Wearable. In addition to that, as of Tizen 3.0, all profiles are built on top of a common, shared infrastructure called Tizen Common.
With Tizen, a device manufacturer can begin with one of these profiles and modify it to serve their own needs, or use the Tizen Common base to develop a new profile to meet the memory, processing and power requirements of any device and quickly bring it to market.
Mobile operators can work with device partners to customize the operating system and user experience to meet the needs of specific customer segments or demographics.
For application developers and ISVs, Tizen offers the power of native application development with the flexibility of unparalleled HTML5 support. Tizen also offers the potential for application developers to extend their reach to new “smart devices” running Tizen, including wearables, consumer electronics (TVs, gaming consoles, DVRs, etc.), cars and appliances.
The Tizen project resides within the Linux Foundation  and is governed by a Technical Steering Group. The Technical Steering Group is the primary decision-making body for the open source project, with a focus on platform development and delivery, along with the formation of working groups to support device verticals.
The Tizen Association  has been formed to guide the industry role of Tizen, including gathering of requirements, identification and facilitation of service models, and overall industry marketing and education.
