NOTES:

Critical: System characteristics which create one of the following combinations of probability and magnitude (Occurrence/[Bodily Injury+System Damage]): (i) Remote AND [Life threatening or death OR Loss of system]; (ii) Occasional AND [Serious or greater OR Heavy or loss of system]; or (iii) Frequently AND [Mild or greater OR Light or greater loss of system]. Usually but always a rating of “Critical” indicates that development of the system should not continue unless the issue is resolved.

Major: System characteristics causing a combination of probability and magnitude (Occurrence/[Bodily Injury+System Damage]): (i) Improbable AND [Life threatening or death OR Loss of system]; (ii) Remote AND [Serious OR Heavy]; (iii) Occasional AND [Mild OR Light]; and (iv) Frequently AND [Negligible OR Negligible]. A “Major” rating indicates that the deficiency may not be sufficiently serious to halt the program, but resources should be allocated to alleviate or reduce the deficiency.

Minor: System characteristics which create one of these combinations of probability and magnitude (Occurrence/[Bodily Injury+System Damage]): (i) Improbable AND [Negligible to Serious

OR Negligible to Heavy]; (ii) Remote AND [Mild or Negligible OR Light or Negligible]; (iii) Occasional AND [Negligible OR Negligible]. A rating of “Minor” is used to indicate deficiencies that are not essential to program completion, but which would enhance system performance if resolved.

Definition

Critical I A system characteristic that, if not remedied, is considered serious enough to prevent the fielding of the system. This characteristic can be expected to result in death of the soldier, abortion of the mission, or loss of the system.

Major II A system characteristic which, if not remedied, could reasonably be expected to result in serious bodily injury or death to the soldier, reduced mission performance, extensive system damage, serious diminished capacity of the system to perform its intended mission, or a significant negative impact on the manpower, personnel, or training requirements of the system.

Characteristics which can be expected to result in death of the soldier, abortion of the mission, or loss of the system may be considered major if the frequency of occurrence is considered remote or improbable.

Minor III A system characteristic which, if not remedied, could reasonable be expected to result in serious bodily discomfort to the soldier, reduced operational effectiveness, system damage, or a negative impact on the manpower, personnel, or training requirements.

Negligible IV A system characteristic that, as the system is currently proposed for fielding, will not have any negative effect on soldier survivability.

This includes characteristics that improve SSv.

Not

Applicable

NA A characteristic that cannot reasonably be applied to this system.

Table 2 - Probability Criteria.

Description Level Code Probability Criteria

Frequent A Likely to occur frequently.

Probable B Will occur several times in the life of an item.

Occasional C Likely to occur sometime in the life of an item.

Remote D Unlikely but possible to occur in the life of an item.

Improbable E So unlikely, it can be assumed that the occurrence may not be experienced.
