I am torn on this a bit.
I like the point system because in the past I have found it useful
for:
a) tracking
b) building teams
c) creating a no blame culture
The reason I am torn is because the points you made on
accountability ring true. Why move away from a unit of measure that
promotes accountability.
The point system helps in tracking when introducing XP to more
traditional forms of development. i.e. as long as the team
completes this many story points every iteration, we will be done by
this date
It helps when building teams sometimes because it hides that fact
that some programmers are more productive then others. Perhaps
another thread could be spun off on this topic alone.
"Do we ever want to hide accountability"
As consultants, we are sometimes brought in to "enable" others to do
what we do. Write code effectively. However, the people we train
sometimes are very green and junior. They have no OO experience,
are new to the technology, and are new to Agile. If we put up
numbers reflecting that one of our guys could lead story and do it
in a day, yet if two of your folks pair on it it would take 5 that
is not conducive to team building.
I guess it depends. If you are on a project of relatively equal
preformers, actuals may work well. If you have a team with wide
deltas in developer productivity however, and your primary objective
is mentoring and coaching, a relative measure may make people better
(but it will be less accountable).
Apologies I am still rambling and torn. Gotta think about this more.
