- Provides common and consistent definitions for IIoT systems, their decompositions and design patterns, and a common vocabulary with which to discuss the specification of implementations and compare options. It also facilitates easy sharing experience and know-how in designing, implementing and operating IIoT systems across industrial sectors.
- Encourages re-use of common system building blocks. A widely accepted, open reference architecture provides guidance to technology vendors to build market-fitting system components and those that are interoperable and applicable to multiple industrial sectors.
- Provides the guiding concepts for the development of IIoT system, solution and application architectures. System implementers can take the open reference architecture as a starting point for design and use it as a framework to choose reusable commercially-available or open-source system-building blocks to reduce project effort, risk, costs and time-to-market.
Technology vendors can evaluate how their technology or solution offering fits with the consensus driven IIRA concepts and methodology and build market-fitting system components that are interoperable and applicable to multiple industrial sectors thereby enabling technology offerings addressing the broadest possible market.
System implementers can use the industry-consensus IIRA as a starting point for design to shorten their path in system development by deploying reusable, commercially available, or open source system building blocks to reduce project risk, associated costs, and time-to-market.
The IIC members and broader IIoT community will use the IIRA concepts to help realize an open and innovative ecosystem, which offers the opportunity to continuously evolve their design in a truly interoperable fashion thereby reducing their cost of design and operations and enabling plug and play with the totality of IIoT offerings.
