Comparing User Experiences: Web, App and Mobile

How can you measure the user experience across the various channels your customers use to interact with you?

With the establishment of mobile web and native mobile apps, your website isn't the only customer touch point anymore. Mike Austin, Director of e-Commerce at RoomsToGo said it best:

"Our customers expect the same experience throughout all our channels no matter if it is the website, mobile site or the real physical store!"

How can you measure the user experience across the various channels your customers use to interact with you? Let's see what we can do to make the user experience quantifiable so we can make informed data-driven decisions.

If we look at the different channel types, they have all two things in common - a user and actions that the user executes. To make this more visual I put the graphic below together. It depicts a common visit of a user with what their common User Actions might look like across each of the channels (Mobile App, Mobile Web & Desktop Web). Although the screens look different the expectations are always the same.

Visit Journey with User Actions for Mobile App, Mobile Web and Desktop Web: All visitors have the same expectations when booking a vacation, regardless of the channel they choose to use

Why You Should Look at User Actions?
User actions are the important element as it exists on the web as well as on the mobile app. It is therefore something we can compare between the different channels. In the above graphic the second user action is "Search for... " The user expects that the time it takes from the touch/click on the search button till the result list is displayed is similar. This timing is now our first indicator for the User Experience; the User Action Duration. We can now compare the user action duration over all the different channels and can work on getting the experience to the industry best practice "3 second promise".

In addition to the User Action Duration, errors have a huge impact on the user experience. No matter if it is a client-side error like a Crash or JavaScript Error, an error occurring in your datacenter like a "Null Pointer Exception" or a Third Party Service not being available, the impact on the user and your business is huge. Some developers try to disguise the errors by presenting "funny" error screens but the negative impact is still there.

The 404 Error Message delivered from might be funny to look at, but the potential impact on your users is nothing to laugh about! See more funny examples at

Looking at the user action duration and the number of errors, we now have two good metrics to quantify the user experience for each user action. But we still have more to investigate to get the overall user experience.

What Additional Information Do We Get by Looking at a Visit?
The collection of experiences across all user actions is what ultimately defines whether the user experience was satisfied, tolerated or frustrated. If we look at a "visit" as a collection of all user actions in the order the user executed them, we can get four very important data points: the first action, the last action, did the visit bounce and if the visit converted. These all help us to identify the User Experience Index. The screenshot below shows us an example of a single visit with every User Action completed. The user started the app, searched for a vacation, tried to book the trip and then the app crashed.

SYS-CON Events announced today that IBM Cloud Data Services has been named “Bronze Sponsor” of SYS-CON's 17th Cloud Expo, which will take place on November 3–5, 2015, at the Santa Clara Convention Center in Santa Clara, CA. IBM Cloud Data Services offers a portfolio of integrated, best-of-breed cloud data services for developers focused on mobile computing and analytics use cases.
Today’s connected world is moving from devices towards things, what this means is that by using increasingly low cost sensors embedded in devices we can create many new use cases. These span across use cases in cities, vehicles, home, offices, factories, retail environments, worksites, health, logistics, and health. These use cases rely on ubiquitous connectivity and generate massive amounts of data at scale. These technologies enable new business opportunities, ways to optimize and automate, along with new ways to engage with users.
The buzz continues for cloud, data analytics and the Internet of Things (IoT) and their collective impact across all industries. But a new conversation is emerging - how do companies use industry disruption and technology enablers to lead in markets undergoing change, uncertainty and ambiguity? Organizations of all sizes need to evolve and transform, often under massive pressure, as industry lines blur and merge and traditional business models are assaulted and turned upside down. In this new data-driven world, marketplaces reign supreme while interoperability, APIs and applications deliver un...
The Internet of Things (IoT) is growing rapidly by extending current technologies, products and networks. By 2020, Cisco estimates there will be 50 billion connected devices. Gartner has forecast revenues of over $300 billion, just to IoT suppliers. Now is the time to figure out how you’ll make money – not just create innovative products. With hundreds of new products and companies jumping into the IoT fray every month, there’s no shortage of innovation. Despite this, McKinsey/VisionMobile data shows "less than 10 percent of IoT developers are making enough to support a reasonably sized team....
Too often with compelling new technologies market participants become overly enamored with that attractiveness of the technology and neglect underlying business drivers. This tendency, what some call the “newest shiny object syndrome,” is understandable given that virtually all of us are heavily engaged in technology. But it is also mistaken. Without concrete business cases driving its deployment, IoT, like many other technologies before it, will fade into obscurity.
SYS-CON Events announced today that Sandy Carter, IBM General Manager Cloud Ecosystem and Developers, and a Social Business Evangelist, will keynote at the 17th International Cloud Expo®, which will take place on November 3–5, 2015, at the Santa Clara Convention Center in Santa Clara, CA.

The IoT market is on track to hit $7.1 trillion in 2020. The reality is that only a handful of companies are ready for this massive demand. There are a lot of barriers, paint points, traps, and hidden roadblocks. How can we deal with these issues and challenges? The paradigm has changed. Old-style ad-hoc trial-and-error ways will certainly lead you to the dead end. What is mandatory is an overarching and adaptive approach to effectively handle the rapid changes and exponential growth.
There will be 20 billion IoT devices connected to the Internet soon. What if we could control these devices with our voice, mind, or gestures? What if we could teach these devices how to talk to each other? What if these devices could learn how to interact with us (and each other) to make our lives better? What if Jarvis was real? How can I gain these super powers? In his session at 17th Cloud Expo, Chris Matthieu, co-founder and CTO of Octoblu, will show you!
Developing software for the Internet of Things (IoT) comes with its own set of challenges. Security, privacy, and unified standards are a few key issues. In addition, each IoT product is comprised of at least three separate application components: the software embedded in the device, the backend big-data service, and the mobile application for the end user's controls. Each component is developed by a different team, using different technologies and practices, and deployed to a different stack/target - this makes the integration of these separate pipelines and the coordination of software upd...
Mobile messaging has been a popular communication channel for more than 20 years. Finnish engineer Matti Makkonen invented the idea for SMS (Short Message Service) in 1984, making his vision a reality on December 3, 1992 by sending the first message ("Happy Christmas") from a PC to a cell phone. Since then, the technology has evolved immensely, from both a technology standpoint, and in our everyday uses for it. Originally used for person-to-person (P2P) communication, i.e., Sally sends a text message to Betty – mobile messaging now offers tremendous value to businesses for customer and empl...
