Class 6 Identifying and Validating Assumptions

Lean is about Learning
Be wary here.
Build the smallest
possible thing you can
to answer a question.

From Google Ventures Design Sprint http://www.gv.com/lib/the-gv-research-sprint-a-4-day-process-for-answering-important-startup-questions

By using Lean Startup, we identify
assumptions before we base our whole
product strategy on them.
Why is it better?

So, what is an
assumption, anyway?

Types of
Assumptions
Problem
Solution
Implementation

Types of
Assumptions
Problem:
Is there a problem?
Solution:
Is this the right way to solve it?
Implementation:
Can you build & sell it before running out of money?

Business concept by Laura Klein. Illustration by Kate
Rutter

“People who have pets are upset by
cost.”
Problem
Illustration by Kate Rutter

“People need a marketplace for pet jobs.”
Solution

“Pets can work!”
Implementation

Do people have trouble
accessing files across
multiple devices?
What’s The Problem?

People Have Multiple Devices
People Want to Access the
Same Files Across Those
Devices
This Is Hard to Do
Problem Assumptions

Are people willing to download
multiple applications and trust storing
files in the cloud?
What’s The Solution?

People Will Download
DropBox on Multiple Devices
People Will Trust the Service
with Important Data
People Understand How
DropBox Folders Work
Solution Assumptions

Can we sync files across
multiple devices quickly and
accurately enough?
What’s The Implementation?

We Can Build a Product that
Syncs Files Across Multiple
Operating Systems
The Product Will Sync
Quickly and Accurately
Implementation Assumptions

For Product to succeed, it is
necessary that

Building is NEVER your
Riskiest Assumption

Ok, Almost Never

Targets Change

A hypothesis statement
should contain:
1. What you believe
2. How you will know if you were right

Problem Hypothesis Example:
We believe people like customer type
have a need for (or problem doing)
need/action/behavior.
We will know we have validated this
when we see
quantitative/measurable outcome or
qualitative/observable outcome. *
*This text was almost entirely stolen from Janice Fraser.

Solution Hypothesis Example:
We believe people like customer
type will solve their problem by
solution behavior.
when we see
qualitative/observable outcome.

Implementation Hypothesis
Example:
We believe our company can provide
solution by implementation method.
when we see
qualitative/observable outcome.

Now You Try It
Write Down:
1. What you believe
2. How you will know if you were right
