Best engineering practices are a set of rules or guidelines used when engineering complex systems. In the field of real-time systems, particularly those deployed in remote or hostile environments, it is often challenging to debug software in the field. Software in this scenario often encounters significant errors in the hardware it runs on. For example, bits in memory (particularly flash memory) are often randomly corrupted and unrecoverable. Interactions between bad hardware and bad software pose significant challenges to debug, correct and obtain proper functionality without replacing physical modules.
