THE THEORY OF AFFORDANCES
You’ve seen these concepts before…
• Software Architects
• Object Designers
• User Experience Experts
• Kanban Experts
• Agile Coaches
• “Systems Thinkers”
6
7
Goal: Design an object that makes it feel natural and easy
to do the right thing.
What is an affordance?
8
An affordance is any perceivable element, such as an object or idea,
that directs a person’s thinking toward a specific set of actions.

The Urinal Fly
“It improves the aim. If a
man sees a fly, he aims at
it. Fly-in-urinal research
found that etchings reduce
spillage by 80%. It gives a
guy something to think
about.
That’s a perfect example of
process control.”

Qualities vs. Functionality
Example: Blend a Drink
• Functions
– Prepare the blender
– Blend
– Clean the blender
• Qualities
– Countertop-ability
– Clean-ability
– Transportability

Functions and Users’ Tasks” Proceedings of IDETC/CIE 2005 18

Gas Engine Motorcycle Throttle
Portable… but noisy.
Application to Software Process
• Example Process Functions
– Write software, test software, release software
• Example Process Qualities
– Plan-ability
– Predictability
– Changeability
– Quality
– Performance
– Reliability
– Estimate-ability
– Harmony

Observations: Arguments about tasking Team over-committing Resist giving up tasks

Values: Baseline for Evaluating Behavior

As a team we valued Predictability Adaptability Respect Open Communication

Reflecting on our practices… “Milestone Owners” Nudge: Attitude of lone responsibility No backlog Nudge: Anxiety over future tasks
Alter Affordances
34
Created a backlog Abolished “Owners” New burndown chart – show progress against commitments
Team Values: Evaluating Behaviors
“Qualities your team values”
• Examples:
– courage
– predictability
– sustainability
– improvability
– measurability
35
– scalability
– responsibility
– feedback
– face-to-face
communication
Examples of Good Affordances
• Iterative planning, light documentation
– Nudge: changeability
• Pair programming
– Nudge: knowledge sharing, performance,
quality
36
Examples of Bad Affordances
• Large planning buffers
– Nudge: procrastination
• Developer Branches
– Nudge: solitary development

LET’S PRACTICE!
What is an affordance?
39
An affordance is any perceivable element, such as an object or idea,
that directs a person’s thinking toward a specific set of actions.

Goals for this Workshop
1. Unlock your mind so you can identify
affordances in your team’s process
2. Practice affordance-driven improvement
in a retrospective simulation
3. Map typical team behaviors to common
agile practices
40
Ground Rules
• When your team is ready to move on, have somebody wear the party hat
• Manage your time, watch the clock!
• Raise your hand if you have a question
• Have fun!
41
Workshop Agenda
1. Establish context, agree on team values
2. Evaluate behaviors
3. Identify affordances nudging your team
4. Propose changes to your team’s
practices
5. Finish posters and share findings
6. Wrap-up

43
Qualities your “team” values
Summary of practices nudge your team’s
behavior
Action items – how to change behavior?
Establishing Context – 2 min
• Task: Introduce yourselves to one another – Briefly share some interesting facts about
yourself and your role(s) at work
• Context: – You are now a team, working together to build a
new awesome piece of software.
– You’ve gathered together for a team retrospective….
44
Agree on Team Qualities – 5 min
• Task: Agree on the 3 – 5 core qualities
you value most as a team.
– Annotate worksheet and add to poster
• Goal: You are going to focus on these
through the workshop and use them to
evaluate behaviors and determine what
improvements to pursue first.

Evaluate Behaviors – 10 min
• Task: Decide whether your team’s
behaviors (Blue Cards) are positive,
neutral, or negative relative to your
values.
• Goal: Learn to observe and analyze team
behaviors in your work environment.
51
52
Evaluate Behaviors – 10 min
• Task: Decide whether your team’s
behaviors (Blue Cards) are positive,
neutral, or negative relative to your
values.

behaviors in your work environment.

55
Identify Affordances – 15 min
• Task: Map practices to negative behaviors.
What affordances nudged your team?
– Try the “5 Whys” technique
– If there is no practice in your deck that you think leads to this bad behavior, use one of the wildcards
• Goal: Have a handful of patterns like this on your poster
<Practice> nudges <Behavior> because ____

Propose Key Changes – 10 min
• Task: Create 2 or 3 action items for your team
and document why you think they will get rid of
the negative behavior
• Goal: Add or remove affordances to your team’s
process. Turn the undesired behaviors into
desired ones.
Practice P(Bad Behavior) Practice P’ (Ø / Good Behavior)
60
Example…
Free dinner nudges developers to stay
late…
Change the Free Dinner affordance
Free breakfast – nudge developers to come
to work early, not waiting for a signal to
mark the end of the day
61
Propose Key Changes – 10 min
• Task: Create 2 or 3 action items for your team
and document why you think they will get rid of
the negative behavior
• Goal: Add or remove affordances to your team’s
process. Turn the undesired behaviors into
desired ones.

Action items – how to change behavior?
Share your findings! – 15 min
• Task: Share your poster!
• Goal: Tell a story so that others can learn
from your thinking process
• Reflection
– Any surprises in your practice/behavior map?
– What can you take back to your team?

WRAP-UP
Goals for this Workshop
1. Unlock your mind so you can identify
affordances in your team’s process
2. Practice affordance-driven improvement
in a retrospective simulation
3. Map typical team behaviors to common
agile practices
66
Practices vs. Affordances?
We simplified things a little for the
simulation…
The world is not this simple.
Affordances can be subtle, tricky to identify.
67
Tools for Retrospectives
• Identify valued team qualities
• “Like to Like” game
– Create your own behaviors and practices card
decks
• Affordance Awareness
– It’s not your fault!
