Correct requirements and perfect design are
like unicorns... a myth.
Machu Picchu by Simon Schwyter
Requirements are not things or documents,
but conversation starters.

Dogfooding is most rewarding when it’s…
disgusting.
@irjastraus
Dogfood #1
Wait, human,
they will...
resolve?!
When business requirement...
...is not clear even to its creator. What will
automagically
do?
Invalid people,
you say?
What are
duplicates?
„Show me the data”.
Are there any unused features?
Are there any unnecessary features?
„If users might fail to recover, there is a
missing feature”.
Are there any
missing features?
complicated features?
„If the team doesn’t understand the idea
the first time, it’s worth challenging.”
Are there any
foggy features?
risks?

Dogfood #2
„Dude, where’s
my data?”
Idea was awesome...
...but hidden from users
And when they finally found it...
...promises were made...
...and feedback came as a surprise.
„User experience is like a joke – if you
need to explain it, means it’s not that
good.”
Is the product
self-explanatory?
easy to use?
„If it’s easy to slip away, there should be
an emergency exit.”
Is the product
too easy to use?
overcomplicated?
„When action is expensive, the system
should provide a clear status visibility.”
Is the product
giving useful feedback?
