Background And Purpose
Preliminary Metrics
TRL
<math> [TRL]_{\text{nx1}}= \begin{pmatrix} TRL_1 \\ TRL_2 \\ ... \\ TRL_n \end{pmatrix} </math>
IRL
<math> [IRL]_{\text{nxn}}= \begin{pmatrix} IRL_{11} & IRL_{12} & ... & IRL_{1n} \\ IRL_{21} & IRL_{22} & ... & IRL_{2n} \\ ... & ... & ... & ... \\ IRL_{n1} & IRL_{n2} & ... & IRL_{nn} \\ \end{pmatrix} </math>
System Readiness Metrics
Component SRL
<math> Component SRL_i=\frac{SRL_i}{m_i} </math>
Composite SRL
<math> Composite SRL=\frac{(\frac{SRL_1}{m_1})+(\frac{SRL_2}{m_2})+...+(\frac{SRL_i}{m_i})}{n} </math>
SRL
| Level | SRL Definition |
| 9 | System has achieved initial operational capability and can satisfy mission objectives |
| 8 | System interoperability should have been demonstrated in an operational environment |
| 7 | System threshold capability should have been demonstrated at operational performance level |
| 6 | System component integrability shouldhave been validated |
| 5 | System high-risk component technology development should have been defined and the vaseline has been allocated |
| 4 | System performance specifications and constraints should have been defined and the baseline has been allocated |
| 3 | System high-risk immature technologies have been indetified and prototyped |
| 2 | System materiel solution should have been considered |
| 1 | System alternative materiel solutions should have been considered |
