DO-178B Traceability   

RelyTRACE . . . Trace Right.
 

Traceability is a key aspect of most modern professions. For high quality and safety-critical engineering development efforts particularly, sfotware traceability is a cornerstone not just for achieving success, but to proving it as well.
RelyTRACE is a highly flexible requirement traceability software application. Its flexibility allows it to adapt to virtually any existing document and development structure without having to modify existing documents to work with RelyTRACE. Furthermore, RelyTRACE allows for any type of hierarchical relationship without imposing any limits on the number of levels it can contain.

For each uniquely different format of tagging, there will be a RelyTRACE parser to correctly extract the traceability tags. RelyTRACE includes several existing parsers for the most popular tagging mechanisms used in the software development lifecycle. If the existing parsers are insufficient for a given document, then a new parser can be developed with relative ease. For customization of your parser contact us or send an email to RelyTRACE<at>highrely-dot-com.
RelyTRACE provides you with a customizable product that severs any type of DO-178B Traceability or DO-254 Traceability Projects:
 
RelyTRACE uses an object oriented approach to traceability, where the user defines the traceability components and the traceability relationship between those components. A typical traceability component structure is depicted in the following diagram. Note that each box represents a traceability component so is thus an object. While the following figure is a typical traceability representation, RelyTRACE enables the user to easily define a different structure, and thus add or remove components in an object-oriented fashion.
 
Reverse Engineering

The aforementioned simplistic approach to traceability indeed has merit, and it is a first step in the right direction. But is it complete? No. Does it satisfy modern engineering standards such as SEI CMM/I, DO-178B Traceability, DO-254 Traceability, IEC-61508, or FDA 510(k) standards? Absolutely not. What are the shortcomings with this simplified approach to traceability?

  • There is no traceability to the implementation components, necessary during the review of such components
  • There is no traceability between increasing levels of requirement granularity, necessary to corroborate the requirements decomposition process
  • There is no traceability to design data, necessary to review and maintain such data
  • There is no ability to isolate extraneous implementation components, such as unused code

To remedy these shortcomings, modern standards require traceability which is more detailed, more complete, and which traces not only forwards but backwards as well.RelyTRACE is unique in that it satisfies such traceability requirements, while allowing the user the flexibility to define the traceability structure and the tagging mechanisms with which to implement that traceability.
