This guide proposes characteristics to help assess the maturity of a resource via the operational definition of the Technology Readiness Level (TRL) indicators: TRL, 7, 8 and 9.
EC definition: "System prototype demonstration in an operational environment"
Resource has passed through the development and is an advanced stage of pre-production: the software is stable, reliable and has been deployed in an operational environment
Functionality as required by the target users is documented, understood, validated with target sample users and accepted by them. Internal documentation exists regarding preliminary validation tests.
An assessment has been made of the required load of the system once the transition into production is complete and a plan has been made to serve this load. This assessment has been documented.
An SLA is optional.
EC description: "System complete and qualified"
There are users who are making real use of the resource and rely on it for their work.
Resource documentation for end-users exists and is made available.
Evidence that the Resource is being delivered in a way consistent with user expectations
Provision is made for user support, with the response to an incident and problem management
EC description: "Actual system proven in an operational environment"
All requirements of TRL 8 are met.
Customer feedback is gathered and documented. The Resource has been in a production state and relied upon by users for at least 1 year and evidence is provided to show this.
There are quantitative outputs as a direct result of resource usage.
