Project Development, Day 3
Agile Software Development
Daily Stand-Up Meeting
We go around the room and report:
- What did you do yesterday?
- What do you plan to do today?
- What is in your way?
Everyone reported on the progress they made
Obstacles: Lack of documentation in code. Need for input
Several pairs noticed the lack of an on-site customer. When
developers have questions, being able to get answers soon
can save a lot of uncertainty and wasted work.
Everyone: pair off, check out a clean copy of the project
svn checkout https://student.cs.uni.edu/svn/810188-May10
... grab a story, and write a test.
Things I noticed:
- The coach let teams remain in the same pairs today,
working to complete yesterday's stories.
- We are bogging down on these stories. Why? I think
this is a result of at least two things unrelated
to XP proper:
- a lack of domain knowledge
- a lack of basic design knowledge and experience
The customer can help with the domain knowledge. The
coach can help with design knowledge (for example, how to
decompose a method that filters a collection of account
entries into a linear search loop and a for-all loop).
For some of you, there is also a lack of Ruby knowledge
that will lessen over time.
- Handling error cases is a big part of writing real systems!
They are not the core of the system, or even a huge part
of the code. But we often bump into "What happens if the
user tries to create an invalid XXXXX?"
Keep in mind that each team member should be doing a couple of
units of work on the system out of class every day. We can move
and shift hours around for pairing, so use your time alone to
to study some of the Ruby you need, or some OO design.
- Homework. None.
- Reading. Just a quick note -- read
It's not a promise, it's a guess
- Programming. Keep learning Ruby, especially any language
features you encountered today but didn't understand well. You
may also work on the team project but only with a partner.
We will continue to do pair programming for all team code.
