Mission Ready Software

 At Mission Ready Software we have been analyzing the root causes of hundreds of thousands of failures induced by software for almost 40 years.  No organization on earth has analyzed more software root causes than we have.  Shockingly, they shrink down to only  a few hundred unique common software defects.  This class covers the top 100 that are the most common AND easiest to spot early in development before the code is even started. Our methodology for predicting the most overlooked defects/edge cases is built on a robust foundation. We began by meticulously compiling a structured list of common software defects, or “edge cases,” that have historically impacted mission and safety-critical systems. This extensive research culminated in the “Common Defect Enumeration” (CDE), a publicly available resource.

Here’s how our process works for identifying the most common software defects

1. First identify the common defect enumerations don’t apply to your system.  For example, if your software doesn’t have machine learning then it can’t encounter machine learning failure modes.

2. Design & Testing Insights: Review the relevant common defect enumerations while looking at your system and software models such as the state diagrams, interfaces, critical sensors.  Don’t focus on individual “shall” statements but instead focus on what’s missing from the collection of shall statements.

3. Actionable Edge Case Software Testing Recommendations: Each of the Common Defect Enumerations can be tested in fault injection testing.  This class shows you how.

4. Requirements Enhancement: Your software specifications and design can be improved by adding or modifying a few controls and mitigations for the common defect, ensuring greater resilience and preventing future defects.
