Mobile Prototypes for Product Managers
Etay Gafni –
Goals – Educating your teams/boss
You’re going mobile
Big Market, Money and Buzz
But, Big risks, investments in new technology
Are you looking ahead or trying save/leverage past investments?
Keep in mind
Keep It Simple Stupid
Story – Writing in Space
Task: Design and develop a writing device
US: Spent millions for a pen
USSR: Used a pencil
Questions you should ask
Which operating systems?
Native or HTML5?
*Are you developing the right app? (for your customers)
Is there demand for this mobile app?
Did we prioritize and validate features with our customers?
How can we create detailed specs for our distributed development team?
How soon can we monetize it?
Will my competitor see my application before my customers?
Fake it until you make it
Get constant feedback from customers
Build the right app with clear specs
shorter time-to market
longer ‘shelf-life’ for the app
The dark side of prototyping
The prototype is the product
The prototype is NOT the product
Everyone is a designer/developer/product manager
Create -> Test on target audience -> Collect Feedback -> Analyze -> Improve
After Analyze -> Lock -> Spec -> Demo/Dev(branch)
Question: How does it differ from web prototyping?
A: Not really different, just keep in mind it is mobile.
Q: How long to you schedule?
A: Depends on scope. You have to ask the right questions.
The main steps
Create, Share, Analyze
Wireframes – basic interaction (paper, ppt)
VP Frame – sketch for Vice President
High Fidelity – designer based
Tool Kit: Paper
The good – fast, cheap, mobile 1/1 feedback
The bad – just low fidelity, hard to manage versions, hard to scale
The ugly – as good as your handwriting
PPT to Photoshop
The good: Fast, Cheap, You know how to use, audience can view
The bad: Focus on high fidelity, not mobile, hard to manage versions
The ugly: Everyone is a designer, can’t collect feedback
The good – real code, can publish
The bad – expensive, technical, is it right?
The ugly – too late, ready to sell

Q: For small companies with a big client, what kind of tools do you use?
A: PDF’s work sometimes, but difficult for online feedback.
Q: How do you collect feedback?
A: Focus groups can be good but hard for mobile. Distributed focus groups can be a solution.
Q: Is it qualitative?
A: I want to understand how they use it without forcing them to tell what they did.
Q: Do you prototype workflow?
A: Yes. You want to know that the functions work. Transitions can come later.

Control the distribution
Test on device and online
Don not try to fix in real-time
Parameters What can we learn
Clicks distribution Navigation
