Standards Body

IEEE 1633 Leadership

Our Founder is the chair of the 2026 IEEE 1633 working group — the governing standard for software reliability engineering.

SAE 1025 FMEA

Section 7

Section 7 of SAE 1025 FMEA based on our 6D CDE Software FMEA approach which is only in Requs AI Software.

World's largest database of software failures analyzed by root cause

CDE Taxonomy inventor

From the CDE,we created the Common Defect Enumeration, the primary taxonomy currently adopted and cited across DOW technical frameworks. Requs AI Software FMEA is the only FMEA tool that takes advantage of the CDE.

02 — Requs Ai Software FMEA

The only true software FMEA tool on the market. The others use hardware centric or ineffective approaches.

Because the SAE 1025 FMEA standards and Common Defect Enumeration originated from our research and data, Requs AI Software FMEA doesn't just align with these requirements — it is the physical manifestation of them.

When your team uses Requs AI Software FMEA, they're utilizing the exact logic expected in these standards.

Other FMEA software
Our solution
Compliant with industry standards
Don't support section 7 or the IEEE 1633 clauses
Software FMEA can be tailored for SAE 1025 FMEA section 7, IEEE 1633, AIAG & VDA, IEC 60812.
Software centric failure modes
Built on a few overused oversimplified failure modes
Focuses in the things that have historically go wrong.
Integrated systems viewpoint
They don't consider that software can fail to handle system failures or cause cascading failure events.
Software doesn't fail in a vacuum so it shouldn't be modeled with that assumption. We use the 6 Dimensional viewpoint.
Fast
They don't do these.
Requs Ai Software FMEA does the three most time consuming parts of the SFMEA. 1) identifying what can go wrong 2) assessing likelihood 3) identifying potential correction actions.
Integration with MBSE
They import for elements for hardware FMECA
Import state models from MBSE
Customizable to your application type and industry
Not supported
Requs Ai Blueprint is an industry specific customization of Requs Ai Software FMEA.
Why Requs AI Software FMEA

Built for efficiency and compliance.

01 — REPORTING

Automated Reporting

Stop manually formatting compliance reports. Requs AI tools are architected to generate the specific deliverables required by international and industry standards

02 — WORKFLOW

Built-in Best Practices

Your software development lifecycle is pre-aligned with industry standards the moment you begin using our tools.

03 — INTEGRATED MULTIFUNCTIONAL TEAM

Collaboration

Supports import/export for multiple team members. Supports integrated safety and RAM assessment.

03 — Requs Ai Software avoids the popular but ineffective approaches

CSCI/hardware centric, "shall" statement, and detailed viewpoints aren't recommended in the IEEE 1633 2026

§1Hardware centric focus

CSCIs are analyzed against a few overhyped failure modes

Focus

Very few failures originate in the entire CSCI.

Better approach

Analyze the things that have historically gone wrong across the system, interfaces and design models.

§2"Shall" statement focus

Individual shall statements are analyzed in isolation

Focus

A small minority of failures originate in a single shall statement.

Better approach

Analyze the requirements as a collective whole.

§3Detailed

Lines of code or code functions are analyzed

Focus

Exhaustively expensive. Only about one third of the failures can be found with this viewpoint.

Better approach

Analyze the design models, interfaces and specifications before the code is written.

Frequently Asked Questions

Common questions

Q1

Is APIS IQ-FMEA suitable for software FMEA?

Answer

APIS IQ-FMEA is optimized for the AIAG-VDA automotive approach, which centers on physical products and manufacturing processes. Software failure modes need a software-specific method — that is what Requs AI Software FMEA is built for.

Q2

What makes a software FMEA different?

Answer

Software does not fail from wear-out; it fails from defects, unhandled edge cases and unexpected inputs. A software FMEA must identify those modes, which is why Requs AI Software FMEA uses the Common Defect Enumeration of real software failure patterns.

Q3

Does Requs AI Software FMEA follow a standard?

Answer

Yes — it is designed around the software FMEA approach in IEEE 1633, the recommended practice co-written and chaired by our founder.
