Here is my take on the problem statements which were of particular interest to me. For ease of scanning, these have been structured as follows:
Improving the user friendliness of the UI and feature discovery
The foremost problem faced by users of Paytm is the usability. Paytm offers a very wide range of verticals, making the platform difficult for customers to use and navigate. This points to an issue in the late activation stage of a user.
Avg. revenue per user
The pain point faced by most users is that they have a hard time finding what they are looking for due to the broad nature of Paytm's offerings. It is therefore important to improve the navigation on app. The goal of the navigation system is to smoothen the user experience and lead users to discover the entire range of Paytm features. This improvement can lead to further improvement in revenues due to increased use of monetized features accompanied by customer data collection through searches.
What Do You Want to Do Today screen
It is a new feature for Paytm customers that asks them what they want to do today and then directly takes them to the relevant section of the product.
The feature pops up as in interface upon opening the application
It contains a list of all the verticals in Paytm along with a short explanation as subtext for each option.
All the verticals can be accessed directly through the interface without having to navigate the different sections of the app.
Discord, despite making a late entrance in the instant messaging social media market, carved a distinct space for itself
Discord creates uniqueness by providing means for users to engage with each other in fun ways without being obvious about it.
The open source bots and community servers lend a sense of closeness to users
Discord makes its product exciting by adding their much fabled Easter eggs
Discord also provides users unprecedented amounts of control to the users (from colour of display names to high pass filters during calls) which cannot be matched by any of its competitors
How Khan academy keeps its students engaged
Online course platforms have a hard time retaining customers for its courses. But Khan academy has managed to achieve that through a variety of means
The first tool used by Khan academy to ensure retention is the UI. Each topic is divided into steps and a wonderfully animated progress bar keeps motivating you to keep learning.
Gamification has been extensively employed in the platform.
Each video watched or quiz taken gets you points, resulting in no action that can be considered 'rewardless' by a user.
The range of badges offered are highly customised for each type of achievement and creatively designed. This makes the user experience much more delight than a standard badge that everyone can get easily.
The badges are displayed on the user profile triggering another reward trigger of social influence and status achievement.
