Redundant final revision states
Explanation:
A search will be performed for revision states with the attribute “no further revision required”, which have further revision states with the same attribute that predate them.
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, there are seven revision states anchored at four different failures. Failure BF1 has three, F1 has two and both BF2 and F2 have one each.
- This Quality Rule identifies any revision state which has the attribute “No further revision required” (e.g. via the context menu), whereby another revision state with the same attribute precedes it. If this is the case, the attribute from the preceding revision state loses any meaning.
- Every status (“completed”, “rejected” etc.) will be considered in this search.
- By viewing the image above, it is possible to see that six revision states have this attribute set. Of these six, there are three that have revision states with an earlier date that also have the attribute set.
Search result: 
This example delivers 3 hits: at BF1 Revision state 06.02.2018 – No further revision required, Revision state 19.06.2018 – No further revision required and at F1 Revision state 19.06.2018 – No further revision required.
