  3. 1. Motivation 2. Visual Design 3. iOS Development 4. Team

    Dynamics
  4. What is Bathchat? Product iOS app for iPhone 4 and

    greater (iOS 7.1) Value Proposition Bathchat facilitates non-committal multimedia communication while bathing via an iPhone app, for software designers and developers. Market Segment People who both use and inform design trends
  5. Why Make Bathchat? WhatsApp/Messenger/SMS want to be your only form

    of communication. Snapchat is a niche medium. Baths are an underutilized niche within the Snapchat niche.
  6. Visual Design Trevor Phillippi

  7. Objectives for Visual Design Since Bathchat itself is a fun

    and immersive product, we wanted the visuals of the product to reflect this. We selected Lato to be used for the typeface since it evokes a sort of playful and inviting feeling The light colors further communicate the approachableness of the product.
  8. Style Guide

  9. xCode Autolayout How do you solve the problem of multiple

    devices/screen widths that could be running Bathchat? xCode Autolayout was introduced specifically to solve this problem.
  10. Contraints By opt+dragging in xCode, you can create a “constraint”

    A “constraint” defines a layout value of a UI element in relation to another element. This can include UI elements as well as screen boundaries.
  11. iOS Development Derek Schultz

  12. iOS Software Design Practices • MVC • Delegation • Singleton

    • Polymorphism
  13. Core Services • UIKit • CoreLocation • CoreGraphics • Parse

    • FacebookSDK
  14. Model–View–Controller • Models: Parse • Views: Storyboard • Controllers ◦

    Login ◦ OutOfBath ◦ Inbox ◦ ViewImage ◦ SendPhoto ◦ etc

    of impulse Challenges Faced Our fourth member left RPI
  23. Exhibit A • Messenger • Slack • Snapchat • Drive

    • FaceTime • Trevor hates SMS.

  27. Fred Brooks, 1986 “No Silver Bullet—Essence and Accident in Software

    Engineering,” 1986 Photo: http://commons.wikimedia.org/wiki/File:Frederick_Brooks_IMG_2261.jpg, 2012 There is no single development […] which by itself promises even one order of magnitude improvement within a decade in productivity, in reliability, in simplicity.
  28. Mills Baker, 2014 “Greg Jorgensen: 'Why Don't Software Methodologies Work?',”

    2014 Photo: https://flic.kr/p/buizyF, 2012 The natural conceptual integrity that results from a really well-selected group of colleagues who "just click" with each other cannot be over-valued; it […] makes methodology a lot less important. So while we're Agile, we try to be much more than that
  29. Common Vision + Crunch Time == Bathchat

  30. Lesson Learned: Pitching We had trouble explaining Bathchat to our

    friends. Sometimes your pitch needs to start with the pain point and then introduce the solution. A pitch is not simply the value prop. Better: Messaging someone is such a commitment. What if the act of sending a message was ephemeral? vs. Worse: Bathchat conversations are non-committal. This is unique and fun.
  31. Lesson Learned: Move Fast Jan 23 — first class of

    Software Design & Documentation Feb 2 — “Hey let's make Bathchat.” Feb 19 — Facebook acquires WhatsApp for $19b Apr 24 — Bathchat beta woo! Apr 28 — Facebook ships Messenger 5.0, uh-oh May 1 — Snapchat ships Chat, godammit May 1 — “Ok now Snapchat is better than our MVP.”
