deal hours first
This is where ideal hours came to the rescue. They were far more able
to wrap their heads around ideal hours i.e. if you lock the developers
and testers in a room with zero interruptions, how long would it take.
I figured that once they got their initial stories estimated in ideal
hours down, switching to Story points will be easy as they would have
established a scale of reference to compare against. This approach
worked really well. They're now into their 3rd Sprint and now that they
have an existing scale, whether the number is in ideal hours or story
points or dog points for that matter, it really doesn't matter any
more. If you're new to agile estimating, and you're having trouble
coming to terms with Story Points try this first and then make the
switch later.
