Dependency of our daily life on software systems is growing for the purpose of convenience, efficiency, and security. Most computer systems are used for long periods of time and are being constantly improved in service objectives and users’ requirements under evolving technologies and changing regulations/standards. These systems have become extremely complex. Dependability of these software systems cannot be achieved solely by using conventional technologies, such as software processes and/or Formal Methods. These systems require something more.
To achieve Dependability in such large and complex systems, this standard introduces the notion of Assuredness. Assuredness is the state for which the Stakeholders of a system have a consensus that confirms that a satisfactory degree of Evidence is provided to ensure that an implementation of an architecture has met the requirements specified to be Assured. Each Stakeholder can then be accountable to that consensus.
Such Assuredness does not necessarily ensure full Dependability of a system, but it may yield insights to improvements to the Dependability of a system. An Architect may use tools such as the DEOS (Dependability Engineering of Open Systems) Framework which adds in a runtime environment to capture information necessary to post-analyze system failures to help make the Architecture more Dependable in the future.
This standard should be used by an Architect wishing to develop an Assured and/or Dependable Architecture. Assured Architectures have the additional artifacts, processes, tools, evidence, and documentation to enable the stakeholders of an architecture to be confident that their architecture’s implementation complies with their stipulated requirements. The information in this standard can be used stand-alone or with an encompassing Architecture Development Method (ADM), such as the TOGAF® ADM.

Dr. Mario Tokoro (2nd photo) is the head of the DEOS project funded by Japan Science and Technology Agency (http://www.dependable-os.net/index-e.html). He established Sony Computer Science Laboratories, Inc. (http://www.sonycsl.co.jp/en/) in 1988 and led it to be one of the world-renowned fundamental research laboratories. He joined Sony Corporation in 1987 to become Corporate Senior Vice President, and then assumed to be CTO in 2000. He promoted networked consumer electronics by introducing architecture-based design and common software platform for consumer electronics products. He played the central role in the establishment of Consumer Electronics Linux Forum (http://www.celinuxforum.org/), CELF in short, which was absorbed in Linux Foundation in 2010 to form the CELF workgroup. Before joining Sony Corporation, he was Professor of Computer Science at Keio University, and held visiting positions at University of Waterloo, Carnegie-Mellon University, GMD, and University of Paris VI.
