Requirements and hypotheses
2:45 with Tomer SharonPeople in the real world have real needs. Let’s see how these needs are manifested in businesses and organizations who develop new products.
Whitney Hess, "What’s Your Problem?"
Stephen Corey, "Professed attitudes and actual behavior"
Ron Cutler, "Why are the British so bad at washing their hands?"
Josh Seiden, "Replacing Requirements with Hypotheses"
Eric Ries, "The Lean Startup"
Brad Feld, "Problem Solving Versus Empathy"
Indi Young, "Practical Empathy"
People in the real world have real needs.
0:00
Let's see how these needs are manifested
in businesses and
0:03
organizations who develop new products.
0:06
This section is inspired by and based on
the work of
0:10
Josh Seiden who highlights the difference
between requirements and hypothesis.
0:14
In many organizations, both big and small.
0:19
Product development and business owners
introduce needs as requirements.
0:22
Sometimes a lengthy spec document is
produced to detail those requirements.
0:28
These requirements are an excellent tool
to use in production mode based on
0:33
known and agreed upon standards.
0:38
An example for requirement is develop a
smart shopping cart for
0:41
grocery stores that will help people scan
and pay for
0:45
their product as they walk through the
aisles.
0:49
A requirement is a way of framing a need
by a product or
0:53
business practitioner to manage the work
of a team.
0:56
Requirements are perceived as necessities
although they are based on
1:00
thinking done by a person who does not
always have access to users' needs,
1:05
behavior or problems.
1:09
Hypotheses are a better way to reframe
requirements.
1:12
They are much more effective for
developing new products under
1:17
conditions of extreme uncertainty as Eric
Reese has noted.
1:20
A hypothesis is a proposed explanation of
the way things work
1:24
that includes both an assumption and a
test.
1:30
What happens if we frame the requirement I
just gave as an example of a hypothesis?
1:33
[SOUND] Let's see.
1:39
We believe that moms who visit grocery
stores with their kids will pay for
1:40
a device that makes their shopping
experience faster and more fun for
1:44
their kids.
1:49
We will know this is true when 1) moms use
our prototype efficiently, and
1:50
2) kids are having fun during grocery
shopping.
1:56
It's easy to see how an hypothesis
includes both an assumption and a test.
2:00
It is also clear that the hypothesis does
not specify the solution.
2:06
It leaves room for the team's creativity
to solve a user problem or
2:11
meet a real need it describes.
2:15
This hypotheses can be easily tested.
2:18
Test results will give the team a very
clear answer whether or
2:21
not the hypotheses is validated are not.
2:25
When you try to understand whether your
target audience has a certain problem,
2:30
it is extremely beneficial to develop
assumptions then test them.
2:34
This validated learning is key to
developing empathy with your
2:39
future potential customers.
