Already existing

• Project vision

• Personas • Context of Use

Preconditions

Goalto decide which functions to put into the application (and which functions to leave out)

Hypothesis Writing

requirements (Anforderungen) and deliverables (Leistungen)

Projects have been framed by

Traditionally

In many cases the deliverables are agreed upon before the work begins, and are noted in a contract or statement of work.

Hypothesis Writing

Instead of deliverables … create an outcome (Ergebnis), to change something in the world

Lean UX

Don’t focus on detailed deliverables!

You are looking to produce changes that improve the product in the here and now – essentially to mould the outcome for the better.

We believemaking the Login Button biggerinfrequent visitors will have an easier time finding the button and will log in at an increased rate

Scheme

Hypothesis Writing



KP Ludwig John

Hypothesis Writing

Start with assumptions instead of requirements Create and test Hypotheses

Measure to see whether we've achieved our desired outcomes

Process


KP Ludwig John

Hypothesis Writing

• basically a statement of something that we think is true.

• They are designed to generate common understanding around an idea that enables everyone to get started.

• It is fully understood that assumptions may not be correct and may be changed during the project as a better understanding develops within the team.

Process

What is an assumption?




KP Ludwig John

Hypothesis Writing

• Which tasks users want to perform? • Which goals do they want to achieve by using the application

• Which functionality do users need for that?

Questions to answer


KP Ludwig John

Hypothesis Writing

Elements of the process

• Who is the user? (Personas) • When and how is our product used? (Context of use)

• What outcome do users want to achieve? • What feature will they need in order to do so?

• How should our product look and behave?


KP Ludwig John

Hypothesis Writing

• What outcome do users want to achieve? • What feature will they need in order to do so?

• What are our measurements for success?might be • better information • higher number of participants • drop of failure rate • cheaper • better quality • more contacts

etc. (depending on the project)

Hypothesis Writing

PracticeGather your team membersBring some Pens and Post-Its

List your assumptions

Pin your Personas on the wall

What outcome do users want to achieve?

then come together in the group to collect and organize your findings in themesUse Post-Its

Basis for UX-Tests

Constant reference for the project development teamthroughout the entire decision making process

Criteria

Description of Functions focussed and in detail

Clearly related to the needs and goals of one or more of your Personas

Determination of measurement(Is this assumption true or nor)


KP Ludwig John

Create a Minimal Viable ProductEvaluate

Prioritize!Decide, which of your assumptions are the most risky ones

Next

Test your Hypothesis

Design a simple experimentto test these Hypothesis first

Prioritize!Decide, which of your assumptions are the most risky ones

TASK

Suggest a simple experimentto test these Hypothesis first

How can you simulate the functionalityof your Hypothesis, simple, fast and focussed!
