Requirements authoring is a tedious process. An inevitable effect of complex and tedious work is the possibility of introducing errors along the way. This is where the requirements review process comes in.
Aerospace Requirements Guide and Checklist: 10 Essential Best Practices for Assuring Compliance with DO-178C
This guide describes ten requirements engineering (RE) best practices aerospace organizations can apply to help assure their avionic software complies with DO-178C. The accompanying checklist is meant to help those organizations embed these best practices, both within their RE process and in the minds of their engineers.
Requirement elicitation is more than simply asking “what are the most important features in product X?”. Stakeholders frequently have ideas, wants or needs floating in the back of their minds, but these may not be clear, even to themselves. So, it’s the job of requirements elicitor to draw these out of the stakeholders and help them articulate their vision, as well as their understanding of the end product.
It’s important to learn from our mistakes, but even more valuable to learn from the mistakes of others. In many cases, best practices develop from what industries or organizations learn from these mistakes. Without effective knowledge transfer, you risk the loss of important organizational knowledge and the associated competitive advantage.
Many safety-critical industries reuse requirements as a way of saving time, however, if this is done incorrectly or without proper steps taken to ensure the reused requirements are still accurate and relevant to the current project, critical errors can occur which cost more than it would to simply author the requirements from scratch.
Knowing which requirements document to use at the correct time can mean the difference between a successful project and one that has taken years to complete. For any project to be successful, good requirements documents are key. Below, we’ll go into detail about which requirements documents are most common, and how they can be used to maximize organization and productivity while writing requirements.
Both business rules and requirements are necessary for fully scoping a system, but what is the difference between the two? When nailing down your requirements doc, it’s important to not muddy the two terms. Let’s get started with some definitions so we can clearly see where business rules and requirements differ.
Writing project requirements, especially for complex or safety-critical products, is a tedious process. Errors are easily introduced at any stage of the process – even before pen meets paper to start writing the requirements document. Here are five ways you may not have thought of that can cause those errors.
