User Experience: In an increasingly large ecosystem, how can we ensure the simplicity and consistency of user experience, avoiding application bloat?

Okay, here is the translation:

Ha, that question hits the nail on the head! As someone constantly dealing with various apps, I totally relate. An app starts out nice and clean, but then it keeps adding features until it turns into this sprawling "octopus." Finding a commonly used function takes forever, and it hogs phone memory like crazy.

For something like LINE Yahoo (LY Corporation), which is already a huge ecosystem unto itself, maintaining simplicity and consistency while preventing app bloat requires understanding and tackling it from several angles. I'll try to explain it plainly:

1. Stick to the "Main Course": Core Functionality First and Foremost

It's like going to a restaurant – you're primarily there to eat. The restaurant can also sell drinks, snacks, or even have music, but its primary job is to make great food served quickly.

The same goes for an app:

• LINE's core is messaging. No matter how many payment, news, or shopping features it adds, the chat interface must be the most prominent and accessible thing when you open the app. I shouldn't have to swipe past three ads and close two pop-ups just to send a message.
• Yahoo's core is search and news. So the search bar and news feed should be its "front door," with other services playing a supporting role.

In short: Don't let flashy features block the main path users want to take. Sticking to what it does best is the first step to avoiding bloat.

2. Do the "Organizing": Put Features Where They Belong

When you have a lot of stuff at home, keeping it neat requires good organization. It's the same for apps. More features don't automatically mean bloat; it depends on where you put them.

• Create "Service Centers" or "Drawers": Like WeChat's "Services" section or the "9-grid Pattern" on Alipay's homepage. Tidy away less frequently used features (like paying bills, ridesharing, movie tickets) into a dedicated spot. Users know where to find them when needed, and they stay out of the way on the main interface.
• Contextual Triggers (Appearing When Needed): For example, if a friend and I are chatting in LINE about "going to see a movie this afternoon," the system could intelligently display a small "Book Movie Ticket" button above the keyboard. This feature "quietly" appears only when relevant and disappears after use, convenient without being intrusive.

An analogy: It's like a toolbox. You don't lay out all your screwdrivers, hammers, and wrenches on the table; you keep them in the box and take out only what you need.

3. Establish "Design Guidelines": Make Everything Feel Cohesive

Consistency is the soul of user experience. An ecosystem has many services, possibly built by different teams, but it must feel unified to the user.

• A Unified "Decor Style": All button styles, colors, font sizes, and iconography should follow one standard. This way, habits formed in Feature A carry over to Feature B, making the experience smooth with minimal learning effort.
• A Unified "Interaction Logic": Tapping "Back" should go back; swiping left-to-right should open the sidebar... these operations must be consistent. The worst is when one page works one way, but a different function uses a completely different logic, making users feel confused, like they're using several different apps.

Imagine: Walking into a chain hotel – whether in Beijing or Tokyo – the room layout, switch placement, and amenities are similar. It feels reassuring and familiar. Design guidelines are the "chain hotel standards" for the app.

4. Build with "Modular Design," Not a "Hotchpotch"

This is a slightly more technical concept, but easy to grasp.

• Build Apps Like Lego: Treat each major function (like Payments, Games, News) as an independent building block (module). The main app on the user's phone is just a "frame." Only when the user clicks on "Games" for the first time does the app download and load that specific "game module."
• The Benefit: For users who never play games, their app doesn't contain all that game-related code and resources. The app remains lightweight, starting faster and taking up less space.

Simply put: Buying a computer, you can choose components like graphics cards or memory. Apps should be like that too – core features are standard; higher-end features are optional add-ons that users "install" as needed, rather than getting a pre-loaded "maxed-out combo" upfront.

5. Put "Choice" Back in the User's Hands

Finally, and crucially, is respecting the user.

• Enable Customization: Let users edit the home screen, hiding infrequently used features and placing the ones they use most often front and center. This way, everyone can have an interface tailored for them, which feels clean and simple.
• Restrained Notifications: For new features, avoid shoving them at users with annoying badge notifications ("red dots") or pop-ups. Have a quiet place to tell users, "We've launched a new feature; check it out if you're interested."

To wrap up:

Maintaining simplicity and consistency in a vast ecosystem is like managing a major city.

1. Clear arterial roads (core functionalities) are needed for smooth flow.
2. Sensible functional zoning and organization (Service Centers) keep the city orderly.
3. Unified architectural styles and traffic rules (Design Guidelines) create harmony and cohesion.
4. Construction needs prefabricated building blocks (Modular Design), not chaotic ad-hoc building, making it more efficient and lightweight.
5. Finally, give citizens some autonomy (Customization) so they can live comfortably.

Doing these things means that even with many features, users will experience the product as efficient and effortless, rather than drowning in a sea of options.
