There are other aspects to production-worthiness I don’t have space to address, and within many industries there are domain-specific standards you need to meet, too. The following are examples:
Defensive programming against malicious code, network activity, and other security concerns
Protection of users’ data from hardware and systems failure, software bugs, and security breaches
Deployment and scale-out performance of software put under great load
…and so forth
Consult a senior programmer for advice: beyond writing code that works—all the time, every time—what else does it take for your code to pass muster?
