Search:
Action groups without valuation
Explanation:
A search will be made for action groups that have not been rejected and for which neither their O or D rating has been defined.
Note 1: In IQ FMEA, it is not the actions but the action groups that count for the evaluation, since there may be several actions with the same type in one action group.
Note 2: An action group is considered rejected if all the actions contained within this group are rejected.
Example:
Abbreviations
- ASIL = Automotive safety integrity level
- BF = Base failure of a base function
- BFn = Base function of a base structure element
- BSE = Base structure element
- Cl Prc = Classification for process characteristic
- Cl Prd = Classification for product characteristic
- Cl Req = Classification for requirement
- CM = Control method
- DA = Detection action
- DC = Diagnostic coverage
- DSCF = Dangerous safety critical failure
- Er Det = Error detection
- Er Resp = Error response
- F = Failure
- FIT = Failure in time
- Fn = Function
- FSM = Functional safety management
- IE = Inspection equipment
- LF = Latent fault
- LFM = Latent fault metric
- OC = Operating condition
- PA = Preventive action
- PE = Process element
- PFH = Probability of failure per Hour
- PMHF = Probabilistic metric for random hardware failures
- PrcC = Process characteristic
- PrdC = Product characteristic
- QM = Quality method
- QR = Quality rule
- Req = Requirement
- RMR = Risk Matrix Ranking
- RP = Reaction plan
- SE = Structure element
- SE ErDet = Structure element for error detections
- SE ErResp = Structure element for error responses
- SFF = Safe failure fraction
- SG = Safety Goal
- SIL = Safety integrity level
- SM = Organisational-SE for “safety mechanisms”
- SPF = Single point fault
- SPFM = Single point fault metric
- TF = Top failure of a top function
- TFn = Top function at root element
- TS = Test sample
- In the above structure, eight preventive actions (PA; Hot-Click-Symbol:
) and seven detection
actions (DA; Hot-Click-Symbol:
) are anchored at various failures, partly with, partly without
deadlines and/or responsibles.
- In the IQ-Software, each action (when linked with a failure) is assigned a standard deadline status. You can define the default status in the document settings. Deadlines can be assigned five possible states. In this example, all five states are used.
- The total of 15 actions are divided into six action groups. Of these six action groups, three groups have neither an O or a D rating. Furthermore, one of these groups has been “rejected”.
Search result: 
Applying the filter to the above structure will lead to finding two action groups that have neither an O or a D rating and are not “rejected”.
These are the action groups found in the revision state at failure BF1 and the initial state at failure BF5.
The action group at BF2 is not part of the result because its complete status is “rejected”.
