I want to blame an improper understanding of agile and lean and 
iterative here, but I won't. On the other hand, I do think that a 
widespread kneejerk rejection of waterfall has also led, in many cases, 
to people rejecting formal requirements analysis and intensive BA work. 
Maybe they've read enough about agile to think that they'll find out 
everything they need to find out when it's time to build Slice 3, and 
it's OK to find out about Slice 3 requirements then, not upfront.

My philosophy - perhaps old-school - is based on these observations over 
the years:

1) In the vast majority of projects of all sizes, the large majority of 
requirements were known and identifiable at the beginning;

2) Corollary to #1: the large majority of requirements do not change 
over the lifetime of a project, of any size. They may be identified 
late, or not at all (before release), but they were always knowable;

3) An impression of changing requirements is almost always due to 
imprecise stakeholder/BA/architect/designer interactions and 
conversations. If you get one answer in April and a different one in 
October, it's either down to who you are asking or what your questions 
are, or both. The actual final "real" requirement probably never changed.

As I say, these are my observations. YMMV. In my case I do substantially 
more requirements analysis up front than maybe other folks do. It has 
served me well. I also do a lot of prototyping and wire-framing and 
proofs-of-concept/technology, all of which in some developer camps seem 
to have been relegated.

Testing is a different art. There is a lot of truth to the saying that a 
good tester is a mediocre coder, and vice versa. At a minimum, if a 
single person does have the expertise to do both, they need to be 
schizophrenic.

Although I've not read anything about it, I've occasionally thought that 
by generally accepted testing principles, that a person who writes unit 
tests (just like any other tests) cannot, and should not, be the 
developer. And yet it's the developer who invariably writes unit tests 
for his own code. Food for thought.

See my thoughts about prototypes, wireframes, Pocs/PoTs above. Using 
those methods I've saved a lot of time over the years. All of them show 
the end-user a good impression of *their* final interface. Which is what 
matters.
