FW: Team A TO DO List.

OOPS 

 

Had older Understanding doc

Here is fixed copy with right success criteria in right order with right
wording

This does not effect the underlying parts though so any work you did is
still valid.

Subject: Team A TO DO List.

 

Team A

 

We are assigned with guideline 1.1

 

We need to be sure that we have at least one techniques/test doc for part of
one solution for each situation in each success criterion.    I have listed
the relevant section from our Understanding Doc below.  

 

I have marked one in each with yellow highlight and [Candidate]

The others are marked in Blue and [Alternate]

 

As you can see there are many techniques that are repeated in different
success criterion.  I have marked them {DUPLICATES}.  We only need to do
them once.

 

 

I have also marked the 'common failures'.    This goes beyond our "one way
to succeed" but if we think they are important we should do them too.  But
do them LAST .

 

We have 23   - most of them pretty straightforward.     3 of the 23 are
'common failures'. 

 

Please let me know which ones each of you can work on.  Post your choices to
the  TEAM-A list so we can all see and chose other ones.
