  8. 8. What is the need? Copyright © Harbinger Systems 8 Mobile apps have become one of the key enablers for any product or service Time to Market is Important - First mover advantage - Catch up with leaders - Grab the seasonal demand Device and platform diversity continues with greater intensity Controlling Cost is Essential - Make smart decisions and spend judiciously - Avoid overruns and recurring costs Increased user expectations have set a new bar Delivering and Maintaining High Quality is Crucial!

  11. 11. Conceptualization Converting your ideas into tangible forms 1. Know your users • Don’t go overboard in supporting platforms/devices • Decide right user experience (UX) 2. Rapidly build application mock-ups with workflows • Finalize application workflows and interfaces early • Honor platform specific UI guidelines • Use rapid wireframing tools like Balsamiq, MockFlow 3. Plan data exchange • Decide roles of server and mobile app • Plan on protocols (REST or SOAP, JSON or XML) 4. Go for Layered approach instead of Monolithic • User interaction: Native UI controls, 3rd party libs, HTML5 • Business logic: Core app logic using classes and controllers • Data Access Layer: Network services and databases Get clarity on how the app would work and understand issues and bottlenecks in early stages to save rework Copyright © Harbinger Systems 11 20%
  12. 12. Development Convert the tangible artifacts into executables 5. Think smarter • Consider the limitations of platforms/devices/networks and follow related guidelines while you design • Build and use common Libraries for app families • Use frameworks like PhoneGap, RhoMobile, Corona 2D for multi-platform apps 6. Don’t hesitate to use Design Patterns • MVC and Template patterns will save effort duplication • Factory method provides better decoupling 7. Don’t compromise on code quality • Use static analysis tools like StaticAnalyzer (XCode), Jupiter (for Eclipse) • Version control add-ons like AgileReview, Crucible (by JIRA) 8. Be Test Ready • Use Unit test frameworks like SenTesting Kit, JUnit • Implement ‘One Click’ build automations (JMeter, Jenkins) These tips will make the code maintainable, detect bugs in minimum cycles and automate tasks - all of which will save considerable time Copyright © Harbinger Systems 12 40%
  13. 13. Testing Ensure that the app is usable and secured 9. Automate • Wherever possible automate the testing, prefer cross- platform solutions. • UI testing using Instruments, FoneMonkey • Data validation testing using TestLodge and TestRail • Implement ‘On Field’ crash reporting service (Custom, JIRA) 10. Test Rapidly and Aggressively • Automation helps in rapid functional testing • Use combinatorial testing methods to increase efficiency of testing on variety of network types, form factors, resources 11. Don’t forget Security • For Android use Package Play, Manifest Explorer, Intent Sniffer and Intent Fuzzer These testing techniques ensure superior quality in a short span of time and reduce the need for bug patches.

  14. 14. Submission Make your app available through publishers 12. Ensure your app does not have these • Compilation warnings • Duplication of native features and controls • Incorrect user notifications • Over usage of native memory • Redirections to web pages • Improper app description in addition to many other common rejection reasons 13. Understand the review process • Honor the Human Interface Guidelines – Display, gesture, orientation, consistency, aesthetic integrity and feedback • Carefully complete the submission documentation • Produce artifacts needed by reviewer Being prepared will significantly improve the chances for one shot approval Copyright © Harbinger Systems 14 15%
  15. 15. Following these best practices, you can achieve nearly 30% reduction in development time and cost without compromising on the quality Simple App : $4,000 – $10,000  $2800 – $7000 Copyright © Harbinger Systems 15 Connecting the dots Ideation Conceptualization Development Testing Submission Distribution Next version
