The process metrics for aerospace software.
| Category | Metric | Definition |
| Metrics of the software history process | NM | The number of modified modules, which is the number of revisions to the software module before the version is released | NDP | New developer proportion, which is the proportion of new personnel participating in the revision’s development | LA | Lines added, that is, the total number of lines of increased code | LD | Lines deleted, that is, the total number of lines deleted code | LM | Lines modified, that is, the total number of lines modified code |
| Metrics of the demand analysis stage in software management | PND | Proportion of new demand | PCD | Proportion of continuing demand | NCD | Number of changes in demand | PDA | Proportion of demand analysts newly joining the project |
| Metrics of the demand design stage in software management | DCR1 | Demand change rate | IDR | The inherit design ratio | PSD1 | Proportion of software designers newly joining the project |
| Metrics of the demand coding stage in software management | DCR2 | Demand change rate | ISD | The inherit ratio of software module | PSD2 | Proportion of new software developers entering the project |
