System Readiness Levels

Background
System Readiness Levels (SRLs) are an analysis of key outputs of an equipment acquisition project structured in such a way as to provide an understanding of work required to mature the project. SRLs are the MoD's preferred method for undertaking IPT self analysis of key phases of an equipment acquisition programme (Initial Gate, Main Gate, Release to Service). This analysis is achieved using a matrix to capture these key outputs and understand how they should mature over time.

The MoD have identified a need to improve the application of techniques and assessments for system maturity measurements within avionics procurement programs when utilising the System Readiness Level (SRL) airworthiness metrics. The ASSC, with its links both within the MoD and Industry, have been tasked by the MoD to undertake this work.

Phase 1
A detailed technical investigation of the material and tools available to AIR IPTs was carried out. The material examined included:

Aircraft Maturity Model - A model containing guidance and process maps giving the IPT the means to track the maturity of the airworthiness compliance of the project.

ASEMS Audit Questions - Audit question set, tailored for avionics procurements, for use when undertaking audits of IPTs.

SRL Self Assessment Tool - An excel formatted tool containing a set of supporting questions for the IPT designed to identify evidence required to achieve levels of project maturity in each system discipline, including Airworthiness.

The SRL Tool was extensively amended to incorporate JSP 553 guidance, enhanced self assessment methodology, the utilisation of a document deliverable maturity matrix and a new In-Service assessment.

Phase 2
The aim of the next phase of the programme is to improve the awareness of airworthiness maturity assessments with SRLs. A series of one day training workshops aimed at safety and programme managers within AIR IPT's responsible for the procurement and upgrade of airworthy equipment will be held. The next workshop is planned for Yeovilton.
