1. What can and cannot be done with Excel FT diagrams can be created using Excel (or other Office tools). However, FT diagrams created in Excel cannot perform safety analyses such as cut set analysis or quantitative evaluations. They also cannot provide explanations for safety evaluations of models at the system level. 2. What cannot be done without specialized tools Cut set analysis, common cause failures, dependent failures, and systematic failures are difficult to express without specialized tools. The Enterprise version allows for revision management during collaborative work. It can also integrate with external tools like DOORS to manage changes during collaboration. 3. Differentiating between Excel and FTA+ For FT diagrams that are not complex and do not have common cause failures, Excel is suitable as it can be created relatively easily without additional costs. For models that are ASIL C or higher, or those that involve common cause failures that cannot be intuitively identified, FaultTree+ with its robust analysis features is more appropriate. When considering tools for ISO 26262 compliance, it is essential to ensure that cut set analysis can be performed.

The hardware architecture required by ISO26262 PART 5 is often quantitatively evaluated using metrics from SN29500; however, a limitation of SN29500 is that it does not correspond to mission profiles. However, ISO26262 PART 11 describes how to apply mission profiles to SN29500. Additionally, a calculation method based on the above approach has been published as a guideline by JASPAR. The document is titled: "Hardware Failure Rate Guidelines Ver.1.0." Our company participates as an editorial member of the JASPAR Functional Safety Working Group and provides a package that includes software for easily performing calculations based on the mission profiles described in the guidelines, along with the SN29500 Reliability Handbook, as a support tool compliant with ISO26262 2nd Edition. This package supports failure rate calculations for both SN29500 and IEC61709.

This document introduces Weibull analysis. In Weibull analysis, the number of failures is used as input to determine the unreliability. Once the unreliability is known, the failure rate and reliability can also be determined. (Refer to the relationship between failure rate and reliability) To express the bias in the occurrence of failures, Weibull distribution is used in failure analysis. By using Weibull distribution, it has become possible to express the bias in the occurrence of failures, including the probability density of failure occurrences.

This document introduces the relationship between failure rate, reliability, unreliability, and failure probability density, among other reliability information. There is a close relationship between reliability, unreliability, failure probability density, and failure rate (which can be viewed from different perspectives as needed); knowing one allows you to understand the other metrics. When managing failures using CMMS/EAM, it is possible to aggregate the number of failures over time. If the number of failures over time is known, the time dependence of failure rate, reliability, and unreliability can be understood. Weibull analysis is a method of failure analysis that leverages this characteristic.
