Lean Design Concepts

Lean Design conceptsJoel EdenPhilly Lean Experiment Meetup, March, 2016

-Lean concepts-Lean human centered design-Lean Experiments

-Lean Coffee / affinity diagramming tonight for meetup topics

Experimental learning

Lean Startup, Lean UX, Agile UX, Agile (as intended)

-Outcomes over outputs (agile is a mechanism of delivery, whereas lean is a mechanism of learning)

-Innovation Accounting (metric is validated learning, as opposed to agile velocity)

-We’re not creating software, were creating value

-Continuous learning

Lean (Startup) Build, Measure, Learn loop

But…

Goal is validated learning (loop around), as fast as possible.

Need to go backwards to plan experiments

1. What is my most important hypothesis?

2. What would I need to see happen to (in)validate it?

3. What’s the fastest, cheapest, least thing I can make or do to test it (learn)?

That’s what MVP means!!!!!

3. What’s the fastest, cheapest, least thing I can make or do to test it (learn)?

Instead of “MVP”:Ash Maurya’s Offer: Unique Value Proposition, Demo of UVP, Exchange of Value

Lean Canvas (1 page alternative to biz plan)(Business Model Canvas Ash Maurya’s Lean Canvas My tweak)

Hypothesis Map (like a user story map, but experiment perspective)

*Separate Problem hypotheses + Solution hypotheses.Fits well with agile (outcome vs output focused).

Goal Directed Design (human centered design)

Goal Directed Design has valid, rigorous design research and interaction design methods…BUT, it’s a bit waterfallish, linear, ~dogmatic.

Personas Scenarios IxFrameworks, IxDesign

Human Centered Design “poured into” Lean loop…

= Non-linear, lean human centered design (“pull” design efforts through as hypotheses require, not as dogma)

Now, there’s no difference between design and research…it’s all just experiments. Any act of “making” (what looks like “design”) is in the act of learning, so it’s both research and design, intertwingled.

Defining experiments from hypotheses

Highest priority item gets tested(place smaller bets, on smaller batches)

Turn assumptions falsifiable hypotheses

Experiments – Problem vs Solution hypothesesSeparate Problem and Solution assumptions and hypotheses.-Problem/Need hierarchy: Exists, Aware, Band aid, Will pay for you to solveWe should only be exploring solutions for validated problems.-Rather than research vs design, everything is an experiment (even production).-A prototype is a question rendered as an artifact.

Example hypothesis types Example useful experiment methods

Problem/need discovery and validation

Ethnographic/observational interviews, diary study, experience sampling

Problem/need frequency Diary study, experience sampling, analytics

Problem/need priority/severity Ranking (during interviews, surveys), analytics

Prob: Personas, scenarios (& customer journey maps for current experiences)

Observational interviews, diary studies, persona clustering analysis

Solution: Terminology, Info org Card sorting, tree test, lostness test

Solution vision and concrete options Test narrative scenarios, storyboards, IxDesign

Solution: Interaction + Visual design Usability testing (observe in context, don’t need lab) using paper or digital prototypes, icon studies

*Value (problem, solution hypotheses) and in what order do we try them?

Value, cost of delay, real option theory

Goal of this meetup: speed this up (keeping validity)

From 1-2 week sprints, to an hour, to 5 minutes?

-Experiment patterns (problem, solution, metrics)?-Reuse of design research data?-Machine learning / genetic algorithms?-???

Lean Coffee method

• List out topics, questions, etc, 1 per post it

• We’ll vote on ones we want to talk about tonight

• Also use all of these ideas to discover what we want to cover in future meetups…so list out anything you can think of you want to see/do
