When building the mobile interface for their existing products, Product Owners are faced with quite a few perplexing questions, especially related to the user experience on mobile. A report from ZDNet says UX is one of the most critical concerns for enterprises looking to develop mobile apps while another study points out that users prefer usability and good user experience over brand names.

Before we start discussing about Mobile UX, let us first understand what User Experience is. User Experience is not only about visual design. It is actually much broader — it involves the scientific research of users and can answer important questions about the audience for both new and existing products. These include:

• Who are your real users and what do these real users care about?

• How do they actually interact with your existing product?

• How will users interact with a new version or new feature?

While there are several UX design best practices from the desktop world that can be brought to mobile, this piece focuses on mobile specific issues.

The foremost thing to remember when building a mobile interface for your product is that while mobile UX design has similarities with web and software design, simply stripping down your desktop or web experience is not going to do it. While drilling down is fine on the Web, mobile users tend to act more linearly a mobile application. To design a good app, you need to start from grounds up, identifying the customer experience you want, and enhancing it with the right features of your existing product. Great mobile apps are uniquely mobile, they couldn’t be done the same way anywhere else.

When choosing whether to design for brand or device, put your preference on device. Your users have been using the device much before they start using your application. Developing custom interfaces will confuse users, slow down adoption, and put a significant obstacle in the way of engagement. Instead, take the principles of the OS-native interface kit, and subtly style your interface elements without altering the underlying functions.

A classic example is the Password Engine iPhone app. iPhone users are used to certain ways to access settings or placement of the Back button. By not following them, the app increases the learning curve for users.

Mobile apps will always be subjected to interruption, whether by an incoming call or the user’s station arriving. Design your applications such that it is easy for users to pick up from where they left off – save states, break larger tasks down into smaller chunks, and put context throughout. Usually users on mobile will on the move, and hence subjected to lots of distractions. Organize content in a way so that it is easy for consumers to browse through. Take the example of the Gmail iPhone app.

All the fields and Call to Action (CTA) are vertically aligned on the left side and thus the user’s eye needs to move in one consistent direction.

While the iPhone app from eFileCabinet forces the user’s eye to scan all around the screen. It has less CTA’s and hence a lot of the real estate on phone screen that could have been used.

Mobile devices generate a lot of information about the user apart from the traditional data generated from a web solution. This includes things like movement, location, sensor data etc. Think about using this data intelligently to pleasantly surprise the user. Customer satisfaction is great but customer delight is even better.

Yelp has recently updated its Nearby feature that now offers suggestions based on user’s location, previous Yelp check-ins and reviews, and Yelp friends as well as other data like the time of day and even the weather. This is a great update because it allows Yelp recommendations to be truly contextual. On a cold morning, it can recommend a good coffee shop while on a sunny day it can point to ice-cream parlours near you.

And finally, understand the limitations of mobile devices – constrained hardware resources, screen size and network bandwidth. Consuming too much power or designing buttons for cursors rather than fingers and thumb will lead users to delete your application. Prioritize and present core features from other channels that have especial relevance in a mobile environment and enable mobile users to navigate to the most important content and functionality in as few taps or key presses as possible.

Measuring UX performance

Like any product feature, you need to constantly measure UX and keep improving. A couple of ways to measure UX are:

1. Data

Identify some of the key KPIs for your app. Example of some of the common ones are:

Adoption: Track data such as DAU or 7 day actives
Retention: Analyze the users who are coming back
Engagement: Number of visits or time spent are good indicators of engagement
Task Success: Use the funnel analysis to figure out dropouts

2. Usability Test

Observe users using the product. Ideally, you would compare these usability tests to ones done on your prior product. Does the new design achieve the intended goals, such as being more intuitive and driving users towards specific actions?

Resources

A great resource to start learning about the UX principles for mobile is the iOS Human Interface Guidelines. Another great resource for learning the basics of iOS UX and UI is Tapworthy: Designing Great iPhone Apps: Josh Clark. Android too has a few Design Guidelines, and it is always good to have a look at them when developing apps for Android.

Conclusions

The mobile user experience encompasses the user’s perceptions and feelings before, during and after their interaction with your mobile presence. Creating mobile user experiences that delights a user forces us to rethink a lot of what we have taken for granted so far with desktop design. Mobile user experience is still a developing field, and opportunities for improvement continue to emerge. But dissecting the mobile user experience into its key components, and placing the user’s expectations at the centre, gives us a conceptual framework for building and evaluating good mobile experiences.

Marketplaces are difficult businesses to run. Like all multi-sided platform businesses, they suffer from the classic chicken and egg problem: the technology has no value unless buyers and sellers are present and you can’t get the buyers on board unless you have sellers and you can’t bring in sellers without having buyers. Hence, building a marketplace is a lot like building two separate companies simultaneously, each dependent on the other.

There are three factors that determine success for a marketplace business:

LIQUIDITY OR CRITICAL MASS

The lifeline of a marketplace (and any platform business for that matter) is liquidity. Liquidity is a state where there are a minimum number of producers and consumers on the marketplace and there is a high expectation of transactions taking place. This is similar to the critical mass of users that is needed on a social network for users to find value in the network. Critical mass is a state where there is enough volume of supply and demand, for transactions to start sparking.

The first and most important metric to watch out for is the percentage of listings that lead to transactions within a certain time period. This serves as a proxy for the efficiency of the marketplace. Merely increasing the number of buyer and seller sign-ups doesn’t serve a purpose unless this metric starts rising. The time period would depend on the category. AirBnB listings would find transactions sooner than listings on a buy-and-sell real estate marketplace. This could also depend on ticket sizes within the same category. Fiverr and oDesk are both services marketplaces but the turnover on Fiverr is most likely higher, owing to the much smaller ticket sizes.

To get to liquidity, the marketplace also needs to solve the chicken and egg problem and get both buyers and sellers on board. Marketplaces leverage a variety of tactics for circumventing this problem including building single user utility, stealing traction and piggybacking other platforms.

MATCHING: CURATION OF PRODUCTS/SERVICE

Users visit a marketplace with a highly transactional intent and want to find what they’re looking for at the earliest. In this aspect, transaction businesses are remarkably different from engagement businesses. A user visiting AirBnB or Yelp has a specific intent in mind. Hence, the quality of the search algorithm and the intuitiveness of the navigation are critical to delivering value. In contrast, a user visiting Pinterest often wants to spend some time and consume content on the platform. Hence, the infinite scroll!

The efficiency of discovery and matching is critical to a marketplace’s success. Percentage of searches that lead to listing profile visits within the first page of results is one such metric. When listings are served instead, as a feed, the clickthrough per session can serve as a proxy as well. The best metric to track matching efficiency varies with the business model of the marketplace as well as the category.

TRUST: CURATION OF PARTICIPANTS

Building trust is central to marketplaces where transactions carry risk. AirBnB is an example of a player in a high-risk category, that succeeded because of its ability to curate its participants. AirBnB allows hosts and travelers to review each other and has one of the highest review rates among marketplaces. It also takes additional measures to build trust, including having photographers certify a host’s listing.

This was one of the factors that helped AirBnB challenge CraigsListbecause CraigsList never built a strong curation system for participants.

Focus on the trust metric is very important to move from appealing to an early adopter audience to appealing to a mainstream audience. While early adopters use new marketplaces because of the novelty, opening up to a larger market requires the trust and reputation management systems to be alive and kicking.

WHAT’S NOT AS IMPORTANT:

User interface and design are less important with transactional businesses as compared to engagement businesses.

On a marketplace, the ability to search and transact/interact should be as intuitive as possible. Beyond that, the look-and-feel and design are purely hygiene factors. Unlike social networks, marketplaces are transactional and users typically don’t have long visit lengths engaging with the product. Hence, UI is not as important a criterion as the other three mentioned above.

In summary, if you’re building a marketplace:

1. Focus on liquidity, not just user growth

2. At critical mass and beyond, closely track matching efficiency

3. When moving from an early adopter to a mainstream audience, ensure that the trust systems are in place and functioning well.
