3At regular intervals, the team reflects on how
to become more effective, then tunes and adjusts
its behavior accordingly. agilemanifesto.org/pr

4Is that a postmortem?
5Project Retrospectives
- A retrospective is an opportunity for the
participants to learn how to improve. The focus
is on learningnot fault-finding. - Norm Kerth
6Agile Retrospectives
- How to mine the experience of your software
development team continually throughout the life
of the project.
7Reflect and find a better way
- Here is Edward Bear, coming downstairs now,
bump, bump, bump, bump, on the back of his head,
behind Christopher Robin. It is, as far as he
knows, the only way of coming downstairs, but
sometimes he feels that there is another way, if
only he could stop bumping for a moment and
think of it. - A. A. Milne
- Winnie the Pooh
8Why a retrospective? To learn from the past
- We want to believe that learning from experience
is automatic, but it requires profound skills. - Experience provides data, not knowledge.
9Why a retrospective? To plan the future
- People want to improve themselves but usually
they dont know what to work on. - When they get good feedback on specific goals,
that releases the natural internal inclination to
improve. James Fallows
10Why a retrospective?To reach closure
- Research shows that when organizations go through
changes, people have feelings and thoughts but no
place to express them in the normal course of
business. Thus, their experience is carried
forward as a heaviness that slows them down and
keeps them from moving into the new setting with
enthusiasm.

Learned, Coast Guard Uniform Lessons Learned - Learning in the Thick of It, M. Darling,

12What a retrospective isnt
- No naming, no blaming. But praise is always
welcome! - Kerths Prime Directive
- Regardless of what we discover, we must
understand and truly believe that everyone did
the best job he/she could, given what was known
at the time, his/her skills and abilities, the
resources available, and the situation at hand.
13Why take so much time?
- Memories are short and selective Challenger
experiment - We tend to focus on recent events, especially if
they are painful - Technical people see technical problems, while
many (or most) of the problems we face are people
problems. - External facilitation is required
14Appropriate times for a retrospective
- At the end of project
- While the project is still running
- At milestones
- Heartbeat
- Custom response to a surprise
15What are the driving questions?
- What worked well that we dont want to forget?
- What should we do differently?
- What did we learn?
- What still puzzles us?
16Agile vs. End of Project
- On an agile project, each iteration should
involve a few small experiments - The retrospective questions should focus on the
experiments, e.g. What worked well about moving
the time of our stand-up? - Agile retrospectives are about getting ready for
the next iteration, not about solving all the
problems the team has. You may not be able to
solve a given problem, but you can always set up
a small experiment.
17Who should attend?
- Represent many viewpoints
- Development
- Marketing
- Customer Support
- QA
- Managers
- May split into specialist groups
- e.g. Testers, Developers, to tackle special topics
18What happensDuring the meeting
- Readying
- Look at the past
- Prepare for the future
19Ground Rules
- Examples
- Try not to interrupt (use a talking stick)
- Speak from your own perspective and not speak for
anyone else - No jokes at the expense of anyone in the room

comfortable talking openly and honestly - Everything is optional
- Secret ballot
- 4 No problem
- 1 No way
- Establish ground rules
21Example Exercises

25What happensDuring the meeting
- Readying
- Look at the past
- Prepare for the future
- Determine actions to take for the next iteration
or release or project - Identify the next experiment
- For agile projects, each iteration should
identify a few small changes and ask the driving
questions about those changes at the next
retrospective
26How is knowledge shared?
- Web postings.
- Team meetings, staff meetings, tech forums.
- Training courses.
- Interaction during checkups and retrospectives.
- Process feedback and knowledge sharing operates
continuously. - Minstrels and story-tellers!

30How to sell retrospectives
- The purpose of a retrospective is learning
- To avoid recurring mistakes
- To identify and share successful practices
- To prepare for the next iteration and future
projects - Everyone says they want to learn, but few take
the time to do so. - Fearless Change patterns for introducing new
ideas, Mary Lynn Manns Linda Rising,
Addison-Wesley, 2005.

33Retrospectivesa closing thoughtfrom Norm Kerth
(and Edward Bear)
- we bump our heads in project after project, day
after day. If we would only take a moment to
stop and think of alternative ways to proceed,
Im sure we could find better ways to do our
work. Norm Kerth
