One aspect of development, which is often overlooked by developers is to create applications that are both easy to maintain and support.

Since software spends 90% of its lifetime in maintenance mode, it's very important that your application is easy to configure, support, and maintain.

Also, the Java application is no different than any other software, you must pay attention to these key properties of writing production-quality code, hence this tip also applies to any programming language which is used to create real-world software which is used by real users.

If you have worked in large organizations e.g. Investment banks like Barclays, UBS, Citibank, or big Insurance companies you will find how important is support and maintenance of production applications are.

There are several more software engineers working in support roles than programmers developing software. You have L1, L2, and L3 support and then a dedicated support team for every application.

This means support is really important.

But, when programmers develop an application, they focus on features and speed of development like how quickly a feature is ready for testing, etc, and to achieve these many programmers including myself in past often ignore things that matter a lot in production.
