program centered process

tab_80

Hi!
Sorry if this is the wrong messageboard..

I'm looking for benefits and drawbacks about using a coding focused(centered) process. I would like a link to a paper about this, if there is any.

Like, instead of writing a lot of documents before starting to code, you just write down the requirements and then start coding a prototype, you learn from that and make it better..

I guess this saves time if the program is quite small, but the bigger (or more comlex) the program, the more you need to plan it.. I want to know more though

Thanks!
