Last year, I got task, I spent more then 10 days time I got as deadline. I tried to learn how things suppose to do as per technology documentation., but my study did not completed, and time passed, then finally I complete the task with putting my efforts by my own way. and complete the task.
But delayed task never be considered to top management.
Now I am wise. I got again a new task, which I never did before. Interesting I got week end. So what I will tomorrow do, just start, and finish the task. Some how I will manage the form and then its transaction. And show the client. Over the week end, I will finished what need to complete.
I will complete my poc. So complete things end to end.
This method called prototyping. Beware, when some time client see almost completed thing, He start to think it is already completed. why you need more time.
So Use it wisely.
