Quality in the Resources - Quality - Time - Scope   Message List  
Reply | Forward Message #25338 of 43457 |
Hello,
 
I'm looking for studies about the "quality".
 
I read in the Henrik Kniberg book that for him, quality is not negociable. I have the same opinion. I also heard some very interesting opinions regarding that at Scrum Gathering when some attendees adressed their concerns about that, telling that in some case, you have to release something even in poor quality, to avoid loosing a lot of money (market shares, competition, contracts, ...). This was in the (excellent) Martin Pichler presentation if I remember well.
 
I'm facing a case where the customer don't care about the quality because for him, this is a waste of time. They have firm deadline, not extensible resources and can't reduce scope. They are willing to rewrite completely the application few months after the release if they really have too. This is definitely not a problem of development cost at all (they can loose millions by not releasing the day of the deadline).
 
I would like to read some articles about the quality subject in this context. The fact that reducing the quality do not reduce time, but that writing good tested code actually reduce risks (and time).
 
Thank you a lot in advance.
 
Pierre
 
PS: the customer don't use Scrum, and won't. This is a general question.
