    Study Notes

    Mobile App Development Lifecycle

    •  The lifecycle comprises five major phases: Inception, Design, Development, Stabilization/Testing, and Deployment.

    Inception (Strategy)

    • Define and refine the app idea
    • Assess competitive advantages by analyzing similar applications and highlighting unique aspects.
    • Evaluate infrastructure integration needs for enterprise applications.
    • Define the value proposition for users and determine how the app will be used.
    • Determine the mobile form factor and how mobile technologies (location, camera, etc.) can add value.
    • Define actors (roles) and use cases (actions/intents).

    Inception (Analysis & Planning)

    • Define clear objectives relating to the specific purpose and marketing campaign for the mobile application.
    • Clearly state the desired outcomes.
    • Specify the exact scope of the mobile application, focused on achieving objectives.
    • Identify the target audience and their requirements, including their needs and expectations.
    • Determine effective strategies to connect with the target audience.
    • Outline on-the-go features demanded by the target audience and how well they can be satisfied.
    • Ensure the app's functionality and user interface align with user expectations.

    Design (UX)

    • User Experience (UX) design is typically done with wireframes or mockups, independent of UI (User Interface) design.
    • UX designers need to consider interface guidelines for different platforms to ensure a consistent user experience.
    • Platforms like Apple (Human Interface Guidelines) and Android offer specific design guidelines.
    • The hardware of mobile devices (physical buttons, screen sizes, etc.) impacts UX decisions.
    • App design should accommodate different form factors (e.g., smaller phones vs larger tablets).

    Design (UI)

    • UI design follows UX, creating the visual design elements like colours, graphics, etc.
    • Strong UI design is essential for popular apps, contributing to a professional appearance.
    • Cross-platform design consistency is key, while a well-designed app on one platform will look different on others.

    Development

    • Development begins early in the lifecycle, following the conceptual/inspiration phase.
    • A working prototype (not just an animation) should be developed to validate functionality, assumptions, and define the scope of work.

    Stabilization/Testing

    • Stabilization is the bug-fixing process, considering functionality, usability, and performance.
    • Early stabilization is crucial to avoid costly fixes later.
    • The app typically goes through stages like Prototype, Alpha, Beta, and Release Candidate.
    • Feedback is crucial throughout the stabilization process.

    Distribution

    • Post-stabilization, the application is published.
    • Various distribution options exist, depending on the platform (e.g., iOS, Android).
    • iOS includes ad-hoc (limited devices) or in-house deployments as well as the Apple App Store.
    • Android has a more open approach with flexibility in app store options, unlike iOS.
    • Certificates play a key role in authenticating apps and developers on both platforms.

    Performance Tracking and Enhancement

    • Application success is measured through factors like download numbers, user engagement time with the app, revenue generated from app use.
    • Continuous evolution is crucial, incorporating feedback and addressing customer needs to make enhancements to the application.
