hypothesis driven development
TRANSCRIPT
@AndrewPirkolanot a consultant
problems we’ll tackle today
perfection
the past
why is perfection bad?
balance
ideas
errors
bring me solutions,not problems
perfection trap
kodak
was kodak a fluke?
the six sigma experiment errors
ideas
why is perfection bad?too much perfection (six sigma) can cause us to miss big opportunities (kodak) and avoid new ideas (unsolved problems)
why is the past bad?
first impressions
confirmation bias
it’s the way we’ve always done things
why is the past bad?it stops us from seeing other possibilities
how might we find more opportunities and new possibilities?

it's a healthy thing now and then to hang a question mark on the things you have long taken for granted
assumptionsbacklogs are things to do
we learn so that we can execute
we need to predict (effort, ROI, etc.), to prioritize
assumptions as questionswhat if our backlog was things to learn?
what if learning and executing were the same?
what if we prioritize learning based on the value we think it leads to?
how might we…
smart people
use questions
bring me problems, not solutions
what got us here,won’t get us…
…somewhere else
how might we find more opportunities and new possibilities?explore questions rather than doing what we know
how might we make a question backlog?
closed questions
as a call center support techniciani want search fields for name and zip codeso that I can quickly get the caller's account info
can we more quickly get account infofor call center support techsby asking clients for a name and zip code?
avoid known answers
can we add a new workflow state by adding it to the state table and creating a workflow in the transitions table?
can we allow users to edit statesby creating an admin utility?
answerable questions
as an Engineeri want code coverage of 80%so that our product quality will be improved
can we Improve product qualityby increasing code coverage to 80%?
can we reduce reported issues by 50%by increasing code coverage to 80%?

how might we write better questions
open & close to craft better questions
it is difficult to talk to bob.
why is it difficult to talk to bob?
is it difficult to talk to bob?
why is it difficult to talk to bob, for me?
open & close to craft better questions
we want better quality.
do we want better quality?
why do we want better quality?
can we reduce late night calls, by regression testing every release candidate?
how might we manage a question backlog?
prioritize & time-box
who wants to learn this >
who best to do this?

yes = proof (working software)
no ≠ failure

how might we manage a question backlog?like today, but with less certainty and with more learning
lao tzuwe mold clay into a pot, but it is the emptiness inside that makes it useful
has this ever worked?
my life as a vb6 engineercontrol triplets for pick listscan we make this better by using a control?
lots of code to bind UI controls to data fieldscan we link controls to data fields by adding properties to controls?
copy paste code to call stored procedurescan we automate server code by generalizing the logic?
copy paste modules for new featurescan we automate workflows by using modules & classes?
how might we try the idea safely?
can we validate these ideasby testing them in a safe place?inspect for learningretrostraininginnovatriumsleadership teamstry an experiment
