Unfinished actions

Explanation:

A search will be made for actions which are either “untouched”, “in progress”, or “under consideration”.

Example:


Abbreviations
  • ASIL = Automotive safety integrity level

  • 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

  • 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


Example A: 004_setting-1

004_SE_setting-1

  • In the above structure, with the following setting 004_setting-1 selected when the document was created, are nine preventive actions (PA; Hot-click icon preventive action) and two detection actions (DA; Hot-click icon detection action) anchored at various failures.  PA1 occurs three times.
  • 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.
  • One of the failures (with actions assigned) is not yet in a failure net. These actions will also be considered in the search.

The results depend on the document setting “Initial state must have a deadline”! The document setting “Initial state must have responsible” does not play a role in this search!

Seven PA’s and one DA, with states: “untouched”, “under consideration” or “in progress” are found in this search. At BF1: PA1 and PA2 (initial state) and PA5, PA9 and PA1 (revision state). At F1: PA10 and at F3: DA8.


Example B: 004-setting-2

004_SE_setting-2

  • The structure list looks different with the following setting inactive: 004-setting-2.
  • This significantly affects the hits found in this Quality Rule.

Search results: Search results

With the above setting inactive, only five actions are considered in this search. From these three are hits: Preventive actions PA5PA9 and PA1.
