The document describes different techniques for agile estimation including team estimation games, color coding of user stories, and dynamic team estimation. It provides examples of how to conduct estimating by placing story cards in order of size, discussing different aspects to consider, and adjusting estimates as a team. The goal is for teams to actively and visually collaborate to refine their estimates.

• Given: a ranked product backlog for a playground

– Place the first (highest ranked) story card in the middle
– Players take turns with two options per player:
Players take turns with two options per player:
• Place the top story card off the stack on its estimated size or
• Move a previously placed card to a new location
– During a turn:
i
• Other team members only ask clarifying questions
• They must not express their own opinions
– When the stack is empty, each player may take one more turn to
move a card
– Assign story point values to each group of cards using a
Assign story point values to each group of cards using a
system you prefer (fibonacci, power‐of‐2,…)

5. COLOR CODING IN PRACTICE
COLOR CODING IN PRACTICE
• Given: an estimated set of User Stories
• Rethink your estimation applying the color coding:
Rethink your estimation applying the color coding:
– What aspects of your stories are important for
estimation? Discuss this with your team
y
• Example: type of materials used, number of pieces, method of
construction, etc.
– Assign a different color to represent each of these
Assign a different color to represent each of these
important aspects, and tag each story card with its
appropriate colors.
– After coloring your stories, discuss your estimates once
again with the team. Do you think any of the estimates
should change?

6. DYNAMIC TEAM ESTIMATION
DYNAMIC TEAM ESTIMATION
• Given: a ranked product backlog for a playground
• Estimate the backlog items with fewer rules:
– Place the cards on the table based on estimated size
– Any team member may move any card at any time
– Many cards may be moving at the same time
– The team should discuss each move as a group
– Assign story point values to each group of cards using a
system you prefer (fibonacci, power‐of‐2,…)

21. Agile
Estimating
2.0
Cheat
Sheet
Team
Estimation
Game
1. Start
with
a
stack
of
ranked
story
cards.
The
team
will
arrange
the
cards
so
the
smallest
size
items
are
on
the
left
and
the
largest
items
on
the
right.
Items
with
the
same
or
similar
size
should
grouped
together
in
vertical
columns
(the
same
place
in
the
left-­‐right
direction).
2. Place
the
first
(highest
ranked)
story
card
in
the
middle
of
the
table
(or
in
the
middle
of
the
board
or
wall)
3. Team
members
take
turns
estimating
in
a
round-­‐robin
manner.
On
each
turn,
the
player
has
two
options,
as
shown
below.
With
both
options,
the
player
will
explain
to
the
team
the
reasons
for
his
or
her
estimate.
a. Take
the
top
story
card
off
the
stack
and
place
it
on
the
table
based
on
its
estimated
size
b. Move
a
previously
placed
card
to
a
new
location
if
you
think
it
should
be
estimated
differently
4. During
a
player’s
turn,
other
team
members
may
speak
only
to
ask
clarifying
questions;
they
must
not
express
their
own
opinions
during
another
player’s
turn.
5. After
the
last
story
card
has
been
estimated,
each
player
may
take
one
more
turn
to
move
a
card
if
he/she
wants
to.
6. Assign
story
point
values
to
each
group
of
cards.
Even
numbered
teams
use
the
pseudo-­‐fibonacci
sequence
(1,2,3,5,8,13,20,40,100),
and
odd
numbered
team
use
powers
of
2
(1,2,4,8,16,32,64,128)
a. You
may
not
have
stories
for
every
number
in
this
sequence.
b. Numbers
represent
the
relative
size/effort
estimated
for
each
story.
For
example,
3
story
points
is
approximately
50%
more
effort
than
2
story
points,
and
8
points
is
two
times
the
effort
of
4
points.
The
Team
Estimation
Game
was
originally
developed
by
Steve
Bockman:
http://stevebockman.com/blog
Using
color
to
visualize
your
backlog
• What
aspects
of
your
stories
are
important
for
estimation?
Discuss
this
with
your
team
o Example:
type
of
materials
used,
number
of
pieces,
method
of
construction,
etc.
• Assign
a
different
color
to
represent
each
of
these
important
aspects,
and
tag
each
story
card
with
its
appropriate
colors.
• After
coloring
your
stories,
discuss
your
estimates
once
again
with
the
team.
Do
you
think
any
of
the
estimates
should
change?

Dynamic
Team
Estimation
(aka
Agile
Estimation
2.0)
In
Dynamic
Team
Estimation,
we
remove
the
rule
that
team
members
take
turns
in
a
round-­‐robin
manner.
Instead,
any
team
member
may
move
a
card
at
any
time.
1. Start
with
a
stack
of
ranked
story
cards.
The
team
will
arrange
the
cards
so
the
smallest
size
items
are
on
the
left
and
the
largest
items
on
the
right.
Items
with
the
same
or
similar
size
should
grouped
together
in
vertical
columns
(the
same
place
in
the
left-­‐right
direction).
2. Place
the
first
(highest

story
card
in
the
middle
of
the
table
(or
in
the

the
board
or

3. Every

1. Take

2. Move
a

card
to
a

location
if
you
think
it
should
be

differently
4. Any
team
member
may
move
any
card
at
any
time.
Whenever
a
card
is
moved
or
placed,
the
player
should
explain
his
or
her
thoughts
to
the
other
team
members.
5. The
team
should
discuss
each
move
as
a
group.
6. After
all
cards
have
been
placed,
assign
story
point
values
to
each
group
of
cards.
Even
numbered
teams
use
the
pseudo-­‐fibonacci
sequence
(1,2,3,5,8,13,20,40,100),
and
odd

team
use

2
(1,2,4,8,16,32,64,128)
7. You
may
not
have
stories
for
every
number
in
this
sequence.
8. Numbers
represent
the
relative
size/effort
estimated
for
each
story.
For
example,
3
story
points
is
approximately
50%
more
effort
than
2
story
points,
and
8
points
is
two
times
the
effort
of
4
points.
