System Readiness Level

System Readiness Level

System Readiness Level (SRL) is an application of ideas originally proposed by Brian J. Sauser as an improvement to Technology Readiness Level (TRL).

The concept of system readiness level refers to the ability to deploy a technological solution as it evolves from initial ideation to its eventual obsolescence. It is a combination of:

1. Technology Readiness Level (TRL)

   TRL measures the success of a scientific principle being repeatedly and reliably applied in a manner that is explained by its theory of operation

2. Integration Readiness Level (IRL)

   IRL measures the adherence of a component to a fault-tolerant black-box model inside a system which relies on it for continued operation

3. Manufacturing Readiness Level (MRL)

   MRL measures the speed at which a component can be produced in quantity to a required standard

While the SRL of a product can be quantitatively arrived at, for the purposes of this site a qualitative score is used. The qualitative score is inspired by examples developed by Sean Ross, and involve two ratings: one on the developmental stage of the technology and the other on the status of interfaces of the technology.

• Developmental Stage Rating

  • "Early Technology"

    This rating indicates that the technology is not mature and proven, and supply beyond single quantities will be an issue.

  • "Reference Design"

    This indicates that a gold-standard for the technology exists against which experts in the field can test new implementations for adherence with design principles. The technology is likely fit for use in its intended application but supply is only available in small quantities.

  • "Mid-level Technology"

    This rating indicates that the a supply of the technology in reasonable quantities is available and the technology has been identified as fit for use in a scenario beyond its original application.

  • "Advanced Technology"

    This rating indicates that the technology exists abundantly for now, but its theory of operation is based on older ideas and may be nearing obsolescence.

• Status of Interfaces

  • "Many Lagging Interfaces"

    This rating indicates that the samples of the technology are not testable and while the technology may be fit for a small number of applications, much work is needed to use it in novel environments.

  • "Some Lagging Interfaces"

    This rating indicates that specialized technicians are likely required for installation and trained operators will be needed to oversee frequent maintenance procedures.

  • "Adequate Interfaces"

    This rating indicates that the technology can be considered functionally equivalent to any other solution with a similar "black box" model when used in a system that does not inadvertently rely on "fringe-benefits" of one or more of its components

  • "Fail-safe Interfaces"

    This rating indicates that redundant or alternate technologies exist that can replace the component in the field, albeit possibly in a limited and short-term capacity.
