| ===Multi-Phase Data===
| | #REDIRECT [[RGA_Data_Types#.28Multi-Phase.29_Mixed_Data]] |
| Reliability data can be analyzed across multiple phases. This is useful when an overall reliability growth program is planned and involves multiple test phases.

| ====(Multi-Phase) Failure Times Data====
| |
| This data type can be used for tests that span multiple phases and the exact failure times are recorded. Figure CECETF shows an example of multi-phase failure times data, where the different events signify failures (F), test phases (PH) or analysis points (AP).

| ====(Multi-Phase) Grouped Failure Times Data====
| |
| This data type can be used for tests that span multiple phases and the exact failure times are unknown. Only the number of failures within a time interval are recorded, as shown in Figure CECErouped.

| ====(Multi-Phase) Mixed Data====
| |
| | |
| This data type can be used for tests that span multiple phases and it allows for configuration in groups, individual trial by trial, or a mixed combination of individual trials and configurations of more than one trial. An example of this data type can be seen in Figure Multi-phase mixed data.
