Way to do Logging

Either you an IT professional or a college student, we all are very excited with projects, that have taken our full time, concentration and effort. Whenever the project has to go live on Production or to be showcased in final assessment in last month of respective semester, we often have to face a question by competitors/evaluators, as

Is your application ready to go into production/to be showcased?

And we know the answers to the same can range from

• All stories are closed
• The whole application was tested end to end
• It satisfies our current needs
• Its scalable and maintainable
• It was proved to work 24/7 without crashing

Even though these assumptions be totally true but they are not enough.

But somewhere inside our mind, we know that

• eventually the application may crash
• a server may go down
• users may complain about a bug that “randomly” appears
• It may stop in middle of the final assessment
• The worst, client could realize that some data is missing and you as a developer don’t had a clue that at which step data got missing.
