Book Notes from 'Scrum - The Art of Doing Twice the Work in Half the Time' By Jeff Sutherland
Time and Time Again
- What makes Scrum so
revolutionary.
- You get more stuff done -
faster and cheaper - twice the work in half the time.
- Eelco - redid his house in 6
weeks
- Decided to make the
contractors use Scrum
- They had weekly projects
they had to move to Done
- They had a board full of
sticky notes listing out the tasks to be completed.
- It made them think and
communicate about the project in a different way than they had before.
- The main thing the stand ups
did -
- Removed dependencies
- Any construction project a
lot of time is spent waiting for one part of the job to be done before
the next can begin.
- Daily Stand up meeting was to
get all those people in a room where they could quickly figure out how to
work together as a team.
- Think about your job
- How much of your job is
wasted while you're waiting for someone else to finish their work.
- For information to be
delivered
- You're doing to many things
at once.
Takeaway
- Time is Finite - Treat it
that way: break your work down into what can be accomplished.
- Demo or Die: at the end of
the sprint have something that’s done - something that can be used.
- Throw Away Your Business
Card:
- Everyone Knows Everything:
communication saturation accelerates work.
- One Meeting a Day: fifteen
minute stand up. See what can be done to increase speed.
Waste Is A Crime
- The heart of Scrum is Rhythm.
- We're pattern seekers, driven
to seek out rhythm in all aspects of our lives.
- What scrum does is create a
different kind of pattern.
- It accepts that we're
habit-driven creatures, seekers of rhythm - somewhat predictable
- 'What if I can take human
patterns and make them positive instead of negative.
- Waste that infects our work,
the cancer that eats our productivity, our organizations, our lives
- When I go into a company I
find that 85% of the effort is wasted
- Only a sixth of the work
done actually produces something of value.
- Taiichi Ohno - Toyota
- Waste is a crime against
society more than business loss.
- Three types of waste
- Muri : waste through
unreasonableness
- Mura : waste through
inconsistency
- Muda : waste through
outcomes
- Demings PDCA cycle
- Plan, Do, Check, Act
- Plan - avoid Muri
- Do - avoid Mura
- Check - avoid Muda
- Act - the will and
motivation and determination to do all that.
One Thing At A Time
- People brag about their
ability to multi-task
- The ability to juggle seems
so attractive.
- The people that multi-task
the most just can't focus
- How painful multitasking is
to your brain, how much it slows you down even when you think it speeds
you up.
- Simply doing tasks one at a
time, instead of switching from one
context to another - half the amount of time it takes
Half Done Isn't Done At All
- Scrum takes a lot of its
thinking from the Japanese manufacturing model
- The United States - this
model is interpreted as Lean Manufacturing
- The idea is to eliminate as
much waste as possible
- Doing half of something is
essentially, doing nothing
- Scrum is a rhythm to the
work.
- Done implies a complete and
deliverable product that can be used by a customer.
- If you are tying up a huge
amount of value in things that aren't delivering value - you wont have
those resources to do other things.
- Jobs that arent done and
products that arent being used are two aspects of the same thing:
- Invested effort with no
positive outcome.
Do It Right the First Time
- Dr. James Womack - Lean
Enterprise Institute at MIT
- Studied manufacturing
- Toyota - when a problem
shows up on the floor - every worker has the ability to stop the whole
line
- When that happens - everyone
swarms to solve the problem.
- Not to yell at the guy -
but to solve the problem.
- There is a reason that
toyota became the number one car manufacturer.
- They did it right the first
time.
- The process is continuously
improved - the right moment to fix a problem is when its observed - not
after the fact
- Do things right the first
time.
- Fix problems as soon as you
notice them - if you don’t you will pay for it.
