Issues Descriptions

Add FHA section to Examples document

  • Key: RAAML12-5
  • Status: open  
  • Source: Boeing ( Mr. David Duran)
  • Summary:

    RAAML contains the ISO 26262 method to support the analysis and requirement specification aspects of Functional Safety. However, ISO 26262 focuses on the automotive industry. To also cover the aerospace sector, the Functional Hazard Assessment (FHA) method according to ARP 4761A should be brought as a method to RAAML and should be properly linked to Core, General, FMEA and ISO 26262 packages.

    The examples document should reflect this change.

ARP 4751 doesn't exist

  • Key: RAAML12-1
  • Status: open  
  • Source: RTX ( Mr. Andrew Muxen)
  • Summary:

    I suspect that this is a typo. I don't think that ARP4751 exists BUT ARP4761 exists. Review and make sure we are referencing the correct standard.

Add Functional Hazard Assessment (FHA) method to RAAML

Add a Causality association class which extends simple Causality association

  • Key: RAAML11-29
  • Status: open  
  • Source: Ford Motor Company ( Mr. Kyle Post)
  • Summary:

    Sometimes the transition from one situation to another situation needs additional properties which cannot be captured by a simple association. The common solution for that is to use an association class to express causality allowing for additional properties to be added to the transition. This pattern is already used in the STPA method. The proposal is to create a general pattern so other methods can access this capability. This would include creating an association class on the common core Situation.

Generalization relation from Situation to SysML Block is not loaded in EA

  • Key: RAAML11-16
  • Status: open  
  • Source: msg Plaut Austria ( Florian Wagner)
  • Summary:

    In Enterprise Architect 15.2 the CoreRAAML.xmi is not loaded completely. The generalization relation from Situation to SysML Block is not loaded. It seems to me that the xmi export has tool-specific content.

STPA is not properly implemented

  • Key: RAAML11-15
  • Status: open  
  • Source: Blue Origin LLC ( Charles F Radley)
  • Summary:

    RAAML claims to implement STPA, but some important elements are missing.

    For example,

    In Step-1 of the STPA process (in the 2018 Leveson/Thomas STPA Handbook – Figure 2.3) it calls out the need to derive “Safety Constraints” from the Losses. I can find no reference to Safety Constraints in the RAAML.

    Furthermore the RAAML does not provide any linkage from Losses to Hazards, which is expected in the Handbook.
