• Front page has: http://www.omg.org/spec/RAAML/, I believe now everything should be https and not http. The above link does get redirected to https, so not a major issue.

• From the official page one and all subsequent pages (page 13 of PDF) the footer is incorrect. It still says: Risk Analysis and Assessment Modeling Langauge (RAAML), v1.0 should be ‘v1.2 Beta’. Also, ‘Language’ is spelled incorrectly.

• Multiple spelling errors were found:

• In section HomogeneousKofNCalculation, below the figure, it says: k ou tof n system reliability or availability, should be k out of n system reliability or availability

• Section 7.3.1 and 7.3.2 has Highway Driving Straight as Speed mentioned 3 times, should ‘at speed’.

• RAAML12-2 – Assumption image in SVG zip file looks incorrect.
Zip file compared to Image in documents ptc-26-04-1

• RAAML12-11 – ProcessModelFlaw is still mentioned in section 10.6.1, page 184 (page 196 of pdf).

ProcessModelFlaw is not marked as Abstract. It must be abstract consistent with the other RAAML library elements. In addition the name ProcessModelFlaw is causing confusion and should be called ControlFlaw to be consistent with the Undesired Control Action and Control Structure.

This is a duplicate of RAAML 12-11

This is an exact duplicate of 12-11 which has been resolved and pushed to voting.

Revise the STPA example documentation to include usages for STPA-sec and to reflect errors corrected in the latest specification.

*Add revised STPA example *

Add revised STPA example to the Risk Analysis and Assessment Modeling Language (RAAML) Examples (Informative) file.

The issue is that Vulnerability is not currently stereotyped as Vulnerability, and is not marked as Abstract, which puts it out of alignment with the other RAAML library elements. To resolve this, the ticket calls for stereotyping it as Vulnerability and marking it as abstract. This change should help ensure consistency with Factors and Limitations in the STPA Loss Scenario

*Partial resolution to make Vulnerability abstract for 1.2 *

Per the RAAML RTF 1.2 working meeting it was decided to partially resolve this issue by updating the Vulnerability to be abstract for 1.2 and defer the addition of the Vulnerability stereotype to 1.3. A new issue will be created for the Vulnerability stereotype addition.

The issue is that Weakness is not currently stereotyped as Weakness, and is not marked as Abstract, which puts it out of alignment with the other RAAML library elements. To resolve this, the ticket calls for stereotyping it as Weakness and marking it as abstract. This change should help ensure consistency with Factors and Limitations in the STPA Loss Scenario.

Add an example for how the elements relevant to security can be modeled by the end user for a security analysis.

Added Security Example

Add the attached example to demonstrate the application of SysML4Sec using RAAML.

ProcessModelFlaw is not marked as Abstract. It must be abstract consistent with the other RAAML library elements. In addition the name ProcessModelFlaw is causing confusion and should be called ControlFlaw to be consistent with the Undesired Control Action and Control Structure.

Update name to ControlFlaw and make abstract

Change name of ProcessModelFlaw to ControlFlaw and any relations and supporting documentation. Update the element to be marked as abstract.

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.

Modify Examples document to include Functional Hazard Assessment (FHA) method

Add FHA subsection to examples document. See the attached .docx files for content of these new sections.
The Functional Hazard Assessment (FHA), as described in the ARP 4761A, is a systematic, comprehensive evaluation of the functional decomposition of a system or platform, performed at early stages of the V development process. This assessment identifies and classifies the failure conditions associated with each function. The goal in conducting an FHA is to clearly identify each failure condition along with the rationale for its severity classification. The classification of these failure conditions establishes the safety objectives to be met.

Define and propose modifications to RAAML 1.2 to include Functional Hazard Assessment (FHA) method.

Minor changes in front matter (chapters 1 through 6), add a new section on FHA in chapter 9 (profile and library), add a new section on FHA in chapter 10 (Views), and addition of subsection to examples document. See the attached .docx files for content of these new sections.

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.

Fix typo to address this issue

In the examples document, there are multiple typos of ARP4761. This proposal addresses these issues.

Revise the associated RAAML .xmi files to represent the changes made in the specification to add the new FHA method

Revise .xmi files to include FHA method

Add FHA.xmi, Add FHALib.xmi, Revise GeneralRAAML.xmi, Revise GeneralRAAMLLib.xmi, Revise ISO26262Lib.xmi, Revise STPALib.xmi to include changes for FHA method
