DO-178C Checklists

Understanding and Using Checklists for Successful DO-178C Program Audits

Have you read the DO-178C standard? How about all the Supplements? Is it clear what you must actually do to comply with DO-178C, what data must be reviewed, how to overlay the Supplements, and what you will be asked during DO-178C audits? Probably not. Are you concerned about this? Probably so. That's why you need checklists.

Checklists are an essential tool to mitigate risks in a DO-178C program . They do this by guiding the teams through all the critical questions that may be asked during certification auditing. This helps ensure the project teams are prepared for their own internal audits and therefore ready for the external auditors.

This "course", which is really a downloadable set of educational and self-explanatory checklists, provides an overview and visual description of how and when checklists are used to drive the reviews that occur throughout the DO-178C process. The downloadable checklists set includes 21 spreadsheets covering over 1000 questions that must be asked and answered to demonstrate compliance in a DO-178C program. The checklists are each explained so applicants can understand how and when to use them, including how to use the Supplements in the context of your DO-178C program. Plus, they are easily tailored by development assurance level (DAL).

This set of checklists also includes an extensive checklist for DO-330, which describes the full requirements and guides you through the process of "Tool Qualification."
