Successful Self-Service Strategy

When it comes to customer service, simplicity is critical. Companies can improve customer experiences primarily by limiting the amount of effort it takes for customers to find answers to their questions and accomplish their tasks. Here lies the appeal of Web self-service, which for many consumers has become the preferred communication channel.

Instantly available, 24/7 online customer self-service portals are gaining ground over conventional agent-assisted support, marking a significant shift in consumer attitudes toward the technology. And, contrary to popular belief, interest in Web self-service technologies is not just coming from younger consumers. The technology is changing the behavior of consumers of all generations. In fact, a recent study by Forrester Research found that 72% of consumers, regardless of age, prefer self-service to picking up the phone or sending an email when it comes to resolving support issues. This certainly is welcome news for organizations looking to cut customer service costs and maximize revenue.

There are several elements to consider for successful self-service strategy.

The success of Web self-service depends on the quality and quantity of the information available and the ease with which it can be accessed. Online customers are extremely impatient and information-hungry, so the material available to customers through self-service needs to be succinct and direct, even in response to queries that are not.

The self-service option has to be easy to find on the Web site. To call more attention to the portal, organizations can prominently place a link to the self-service portal on the homepage and other common support pages that feature company, product, and services information. And, since a self-service portal is an extension of a company's Web site, it should have the same look and feel as the rest of the site.

Once on the portal, 80/20 rule applies which means that you assume that 80% of site visitors are looking for about 20% of the content, so that 20% should be easy to find.

As for the content itself, it should be clear, to the point, and easy to understand. This can be achieved by including graphic elements, such as diagrams, charts, and bullet points. When doing so, make sure the graphics are optimized for the Web. If they're not, the Web site could take too long to load, which might cause some customers to abandon it for a more costly agent-assisted channel. Consider keeping content to an eighth-grade reading level, so the average 13- or 14-year-old can make sense of it.

Ensuring accessibility also means that the site should support a variety of Internet browsers, operating systems, assistive technologies for the blind, and, of course, mobile platforms. The latter is becoming more important, especially when one considers that almost a third of all Web traffic today comes from mobile devices.

To make a self-service section even more effective, it can be combined with an automated guidance system that enables site visitors to enter questions and then takes them to specific responses without forcing them to scan an entire database for the answer they need.

One such system is marketed by WalkMe, a San Francisco start-up that enables Web site owners to enhance their online self-service options with interactive on-screen step-by-step instructions displayed as pop-up balloons. The balloons can be programmed to appear automatically when the site visitor rolls his cursor over certain items or when he clicks on a help button.

Customers who can't find answers on their own in a self-help knowledge base might be inclined to call a customer service line, but they are more likely to type their question into a Google search bar, and companies have no control over the results that the Google search returns. This presents a number of problems for a company. Not only has the visitor left your site, but he can find information that you may not want him to see.

Virtual agents are another option companies can use to help customers find what they're looking for. IntelliResponse's Virtual Agent technology simplifies its Web self-service options. The software helps site visitors to find the single right answer to their questions. To keep information current and relevant, it strips outdated FAQ entries, learns over time how to group and respond to questions, and captures data about customer service queries to find precisely what customers need so your organization can fine-tune how it presents information on its Web site.

Companies can also use Web chat to help customers through the self-service maze. It's a tool that's already widely accepted by consumers and businesses alike. LiveWebAssist chat enables agents to push prepared content such as photos, graphics, or Web link, to customers on the site with a single click.

Along with chat and virtual agents, companies can use assisted browsing, or cobrowsing, to move self-service interactions along. This functionality lets the agent—or possibly the virtual agent—temporarily take control of a customer's computer screen. Not only does this improve the self-service experience, but, when interactions move to the contact center through either phone or chat, co-browsing can reduce the average handling time.

It is important to measure response time. Perhaps the most effective measure is the number of customer questions that are submitted and get a response. This can apply to those questions where the customer finds the answer on her own as well as those that are answered through a social community or by a representative of the company. Consider these elements:
  • the number of issues resolved per month through social communities. This includes the number of new questions posed to and answered by the community, the percentage of issues resolved by members of the community rather than company employees, and the number of "this article helped me" votes received.
  • the number of issues resolved every month through FAQs and company knowledge bases. This includes the number of page views that both receive per month.
  • the average cost to resolve issues through channels that involve a company employee. These include phone, email, and chat.
And then, as with any customer service channel, it's important to collect user feedback about the self-help experience. As with any other customer service channel, this can be done through customer surveys, Web analytics and search logs, customer interviews and focus groups, usability testing, and collaborative design processes.

For self-service to be done right, it should be in the interest of the customer. You do not want customers to use self-service because they are forced to. You want them to use it because it serves their needs.

Is Your Web Site Optimized for Mobile Devices?

Many people are highly dependent of their mobile devices for every day interactions, including mobile commerce. Our society is becoming highly mobile and connected. In the latest Shop.org and Forrester Research Mobile Commerce Survey, it's estimated that U.S. smartphone commerce will grow to $31 billion by 2016.

Those organizations that can best serve mobile customers will have an advantage in the competition. With a surge in mobile traffic comes the added potential to connect with and sell to customers through mobile commerce. Having a concrete mobile infrastructure plan and strategy is no longer an option, as it had been in recent years, but rather a must to compete in any customer-facing situation.

But despite this upward trajectory, retailers and other consumer-oriented companies still express some hesitancy about investing in multi-device environments. There is still some apprehension by companies, when it comes to moving forward with mobile planning. Companies still struggle to maintain uniformity across multiple device experiences when there are various screen sizes, operating systems, hardware specifications, and loading speeds to consider. One fear is that of the unknown, but security, data management, and simply proving a use case and subsequent return on investment are concerns as well.

The key issue in smartphone shopping continues to be the form factor, which can make navigation more difficult for customers. In addition to slower page load times on smartphones, some customers are concerned about the security of the transaction or simply complain that the experience just is not the same.

A successful mobile experience, like many other customer experiences, is about fulfilling customers' needs. First-time users of a mobile site or app tend to be less satisfied with their mobile experiences than frequent users because of their lack of familiarity with layouts, navigation, and functionality according to the survey of the mobile users. Knowing the different kinds of mobile devices customers use is critical. It is pertinent to develop a strategy that encompasses all types of customer scenarios.

Before embarking on any one mobile strategy, it is important to learn how your company's customers most likely would use their mobile devices. In addition to enabling customers to interact how they wish, any company looking to optimize its mobile presence must naturally consider the effects on the business as well, and how mobile usage will impact other lines of business and cross-channel marketing efforts.

In addition to justifying a use case and ROI for mobile, companies that wish to get into the mobile side of business must be aware of its limitations. Under ideal circumstances, companies want to engage with their customers and cultivate a one-to-one relationship while taking into consideration CANSPAM and privacy regulations. It is very important to adjust taxonomy and information architecture for the mobile experience. A lot of searches are made using mobile devices, so search also has to be optimized.

Optimizing your mobile site or developing a native application is no simple task. There are security considerations, as well as device-specific functions, to consider. Don't take a cookie-cutter approach. Some companies make the mistake of simply cloning online information without considering that consumer behavior on the mobile phone is dramatically different. Justify mobile ROI with consumer insight.

Consider security. Create a military-grade security infrastructure, while maintaining user-friendly design. Hire the best user interaction designer to design the security setup interaction.

Utilize mobile wisely. Once someone has discovered your brand through search, referral, or a marketing message, and they download the app, this may indicate a loyal customer. The app can be a great way to maximize and monetize that loyal relationship because it's in a controlled environment.

Optimize Web Experience Management


Leading enterprises strive to acheeve higher levels of customer engagement through online channels, and this means they must easily, quickly and cost effectively provide fresh, personal, relevant content anytime, anywhere, on any device, through a consistent and dynamic user experience.

Traditional web content management system (CMS) solutions are no longer sufficient, and a richer and broader range of capabilities that enable web experience management - managing and optimizing the site visitor experience across the web, mobile apps, social networks and more - must now be leveraged in this new era of engagement.

The Need for Web Experience Management

Over the last few years, the Internet has undergone a tremendous amount of fundamental change in its landscape - socia1, personal and mobile.

1. Social - The Web is becoming increasingly more social and much less anonymous. The power of sharing can enhance or destroy brands in seconds.

2. Personal - While the Internet is continuously expanding in terms of ubiquity, at the same time it's becoming much more local and much more personal in terms of user experience.

3. Mobile The growth of mobile access to the Internet is rapidly expanding to the point where access from tablets and phones will soon exceed that from desktops and laptops.

The very way we communicate with customers is changing, and when fundamental change like this occurs, those who recognize the change and move quickly to adapt will benefit the most.

A New Era of Engagement

Each of these trends reinforces the others and fuels further adoption and innovation. It is these technologies, the behaviors and capabilities they foster that have brought us to a new era which Forrester calls the "era of engagement."

Driving these trends are people - our friends, leads, customers, critics, and fans. This is our audience and the other half of the conversation, and in today's age of engagement, they want to participate and expect us to engage them on their terms, on their schedule, in the context of their location, in their language and optimized for their device. To effectively tackle this challenge of serving a mass audience with limited resources, enterprises require strategy and effective tools to help get the job done.

Web experience management (WEM) provides us with the tools to take on this otherwise daunting task. The capabilities of WEM allow you to create, manage and deliver dynamic targeted and consistent content across various online channels including your website, social media, marketing campaign sites, mobile applications, etc. It takes a lot more than a traditional Web CMS to meet these new demands.

Key Principles of Web Experience Management

To effectively implement WEM, enterprises must start with their business strategy and goals which should drive their messaging and engagement strategy and which in turn should drive their content strategy. In other words, the strengths, weaknesses, threats and opportunities that businesses face should be considered first and foremost.

Too often organizations fail to do this by jumping straight into a technology selection without due consideration of the business drivers. Around this foundation, we wrap the fundamentals of basic Web content management. It is important to remember that content is still king. Business users and marketers need easy to use, yet powerful, content authoring and publishing capabilities.

They need rich content models that allow them to create engaging visitor experiences, to easily create new content assets, to quickly find and re-purpose existing content, and to preview content and the site visitor experience for all online channels.

Upon this foundation, an effective WEM solution provides a comprehensive collection of capabilities that allow organizations to create, manage and deliver dynamic, targeted and consistent content and visitor experiences across multiple touch points -corporate website, dedicated marketing campaign sites, mobile applications, social media sites, etc.

While WEM requirements are going to vary from organization to organization, some of the most critical features needed by essentially all enterprises include content targeting and personalization, mobile device support, faceted search and navigation, multi-channel publishing, integrated Web analytics, and campaign management.

Realities of Online Self-Service


Forrester Research says that business leaders must dramatically revitalize the self-service experience offered on customer facing websites just to keep pace with evolving consumer expectations. There are key realities of modern online service that expose the gap between customer expectations and website performance, and how you can take steps to close that gap starting now.

1. Customers have grown tired of your old online help tools.

Customer satisfaction with today's most common web self-service features is abysmal and is getting worse. In 2011, only 51% of consumers who used online help sections or FAQs for self-service were satisfied, down from 56% in 2009. As more companies rectify this by deploying next generation self-service solutions and virtual agents, fewer customers will tolerate antiquated self-service help tools online.

2. Customers now expect a superior experience online, not just a good one.

Exceptionally positive online experiences are now setting the bar for what customers expect when they visit virtually any website in search of answers and information. According to Forrester, 70% of online consumers expect businesses to try harder to provide superior online customer service.

3. Consumers arc impatient and protective of their time.

Consumers cite "valuing my time" as the most important thing a company can do to deliver a good online customer experience. Yet most websites are complex, hard to navigate and filled with content that provides multiple possible answers rather than a single, swift path to resolution.

4, Customer service has gone mobile.

Mobile phones are now ubiquitous. Nearly 88% of US adults own them, and 27% of US adults are already considered "super-connected" consumers, using their phones for information. research and commerce. What is more, digital tablet sales are predicted to outpace sales of PCs by 2015. Convenience and ease-of-use are the hallmarks of these mobile form factors. Websites that offer experiences contrary to these attributes will only raise the ire of today's increasingly impatient and unforgiving mobile consumer.

5. Social media is increasingly embraced as a customer service tool.

Back in 2009, just 1% of consumers used Twitter for customer service. This number jumped to 19% in 2011. Delivering a consistent service experience across multiple channels is critical, especially today, as consumers are not shy about using social media sites to publicly complain and vent frustration about any interactions with companies that fail to satisfy.

6. Dissatisfaction online = hijacked revenues.

One of the most appealing benefits of delivering a positive experience in the web channel is the opportunity for organizations to provide information that supports and encourages purchase decisions. Online, the shift from a customer service conversation to a purchase consideration conversation can be a very natural and systematic progression. This progression is thwarted, however, the moment a self-service experience fails to satisfy.

The impact of the self-service experience on revenues should not be underestimated. Fully 45% of US online consumers agree with the statement: "I am very likely to abandon my online purchase if I cannot find a quick answer to my questions."

These trends underline the urgent need to revitalize the online service experience offered by most companies. Online self-service is in need of resuscitation. Useful web self-service and virtual agent technologies that can deliver an enhanced customer experience are currently underutilized.

Where To Go from Here?

What should your organization do as the first step toward improving the online customer experience?

Begin with an honest and objective assessment of the self-service experience your website offers today. Looking at your customer facing website, ask yourself these three questions...

1. Is there a single, highlly visible starting point for self-service activity?

Today's consumers are task oriented when they go online. Your customers want their self-service journey to begin immediately and move swiftly to completion. Looking at your home page or most highly trafficked customer service page, ask yourself if the average customer would be able to identify the clear starting point for any customer service-related task in a matter of seconds. Any required navigation or clicking through to new pages is viewed as time waste and is out of alignment with their expectation.

2. Is issue resolution generally a multi-step or a single-step, activity?

When looking for information online, customers want a single accurate answer that is accessible in one step. Any content page that offers more than one alternative answer or path to an answer, requires your customer to take additional steps for sorling, scanning content and/or comparing answers. On your website, when results are served, is the customer presented with a single answer, or multiple results to sift through?

3. How will you measure how your site is performing?

A quantitative assessment of your self-service performance is the first thing you will need to establish for any improvement to the self-service experience. A free online self-service assessment tool, created by Forrester and InielliResponse, is vendor-agnostic methodology you can use for scoring your site's performance and charring a path for improvement.

Website Usability

Web usability is an approach to make a web site easy to use for a user, without the requirement that any specialized training is undertaken or any special manual is read. Users should be able to intuitively determine the actions they need or can perform on the web page s, e.g., press a button to perform some action.

Some broad goals of usability could be: present the information to the user in a clear and concise way, give the correct choices to the users in an obvious way, remove any ambiguity regarding the consequences of an action (e.g. clicking on delete/remove/purchase), place important items in an appropriate area on a web page or a web application.

When you designed your web site, you want to promote it everywhere with big bold letters saying, "Hello everybody! Come and look at my web site! It is just great!" When you submit your web site to forums for web site reviews, you may write, "What do you think of my web site?"

This is the big mistake to ask someone to look at your web site. There is never a single answer. To understand if your web site meets its usability requirements, ask people to try it out. They should be able to answer the following questions: what is the purpose of this web site? what can I do here? what needs does it fulfill?

The 5 seconds test tool is one way to explore immediate impressions of the web site users. You can experiment by asking them what the site is about, to see if the site’s purpose is communicated clearly.

The biggest mistake is to believe that web site appearance matters the most. How it looks is only one part of the process. How it performs is another. What it can give back to site visitors and how effectively it conveys that information will matter even more.

Writing content for web users is an important task. The main goal of this task is the ease with which the web site content is read and understood by your users. When your content is highly readable, your audience is able to quickly digest the information you share with them.

Keep the web site content as concise as possible. Users have very short attention spans and they are not going to read articles thoroughly and in their entirety. So, get to the point as quickly as possible. Place your most important content high on the page. Think of a newspaper: the top story is always prominently displayed above the fold. Use headings to break up long text. Use bulleted lists where possible.

Format the text in such a way that it is easy to read it and just to scan a web page.Keep colors and typefaces consistent. Visitors should never click on an internal link in your site and wonder if they've left your web site. Choose your colors and fonts carefully and use them consistently throughout the site.

Keep page layout consistent. Use a Web site template to enforce a uniform page structure. Visitors should be able to predict the location of important page elements after visiting just one page in your site.

Design a clear and simple navigation system. a good navigation system should answer three questions: Where am I? Where have I been? Where can I go?

The navigation system should be in the same place on every page and have the same format. Visitors will get confused and frustrated if links appear and disappear unpredictably. Don't make your visitors guess where a link is going to take them. Visitors should be able to anticipate a link's destination by reading the text in the link or on the navigation button. Users don't have time or patience to guess.

Large or complex sites should always have a text-based site map in addition to text links. Every page should contain a text link to the site map. Lost visitors will use it to find their way, while search engines spiders will have reliable access to all your pages.

Include a home page link inside your main navigation system. Visitors may enter your site via an internal page, but hopefully they will want to head for the home page. Link the site logo to the home page. Most sites include their logo somewhere at the top of every page - generally in the top, left-hand corner. Visitors expect this logo to be a link to your site's home page. They'll often go there before looking for the home link in the navigation system.

Include a site search box. A robust site search feature helps visitors quickly locate the information they want. Make the search box prominent and be sure that it searches all of your site, and only your site.

Check your page display at in a number of different screen resolutions to make sure that your most important content is visible when the page loads.

Include a form for users' feedback on your site.

A good brand creates or reinforces a user's impression of the site. When your site is strongly branded, that means that visitors will think of you first when they go shopping for your product or service.

Conduct usability testing. Usability testing helps you to replicate the experience of the average web site user and correct problems before real users find them.

Methods and Techniques for Information Architecture Design

Yesterday, I described information architecture design patterns for web sites and best practices for this design. Today, I am going to describe methods and techniques for information architecture design.

There are a few different approaches commonly used for information architecture design.

Card Sorting

Card sorting is a low cost, simple way to figure out how best to group and organize your content based on user input. Card sorting works by writing each content set or page on an index card, and then letting users sort them into groups based on how they think the content should be categorized.

There are several types of card sorting methodologies. The basic method starts out with cards in random order and users sort them in the way they think they should be grouped. In reverse card sorting, the cards are pre-sorted into groups, and users are then given the task of rearranging them as they see fit. Open card sorting lets users name the groups they’ve created for the cards, while closed card sorting will have group names in which the participant places the cards into.

Various methods can be used to analyze the data. The purpose of the analysis is to extract patterns from the population of test subjects, so that a common set of categories and relationships emerges. This common set is then incorporated into the design of the site, either for navigation or for other purposes.

There are a number of tools available to perform card sorting activities with survey participants via the internet. The perceived advantage of remote card sorting is that it allows a larger group of participants to be reached at a lower cost. The software can also assist in the process of analyzing card sort results. The advantages of a remote card sort must be traded off against the lack of personal interaction between card sort participants and the card sort administrator, which may produce valuable insights.

Wireframes and Prototypes

Basic wireframes can do a lot more than just give an outline of the design layout of a site. It also informs us how content will be arranged, at least on a basic level. Putting content into wireframes and prototypes gives us a good sense of how the content is arranged in relation to other content and how well our information architecture achieves our goals.

When you are wireframing, and especially when you are prototyping, you should be working with content that at least resembles what the final content of the site will be.

Site Maps and Outlines

Site maps are quick and easy ways to visually denote how different pages and content relate to one another. It is an imperative step that "mocks up" how content will be arranged.

These content outlines show how all the pages on your site are grouped, what order they appear in, and the relationships between parent and child pages. This is often a simple document to prepare, and may be created after a round or two of card sorting.

For existing sites or content that must be placed in a web site, a content inventory is usually the prelude to this phase.

Information Architecture Design Styles

There are two basic styles of information architecture: top-down and bottom-up. The thing that many designers must realize is that it is useful to look at a site from both angles to devise the most effective IA. Rather than just looking at your projects from a top-down or bottom-up approach, look at it from both ends to see if there are any gaps in how things are organized.

Top-Down Architecture

Top-down architecture starts with a broad overview and understanding of the website’s strategy and goals, and creates a basic structure first. From there, content relationships are refined as the site architecture grows deeper, but it is all viewed from the overall high-level purpose of the site.

Bottom-Up Architecture

The bottom-up architecture model looks at the detailed relationships between content first. With this kind of architecture, you might start out with user personas and how those users will be going through the site. From there, you figure out how to tie it all together, rather than looking at how it all relates first.

Different websites require different types of information architecture. What works best will vary based on things like how often content is updated, how much content there is, and how visitors use the site.

Information Architecture for Websites

Without a clear understanding of how information architecture (IA) should be set up, we can end up creating web sites that are more confusing than they need to be or make web site content virtually inaccessible. Here are some popular IA design patterns, best practices, design techniques, and case examples.

Information Architecture Design Patterns

There are a number of different IA design patterns for effective organization of web site content. Understanding these IA models will help you pick the most appropriate starting point for a site’s information structure. Let us talk about five of the most common web site IA patterns.

Single Page


The first pattern is the single page model. Single page sites are best suited for projects that have a very narrow focus and a limited amount of information. These could be for a single product site, such as a website for an iPhone app, or a simple personal contact info site.

Flat Structure


This information structure puts all the pages on the same level. Every page is just as important as every other page. This is commonly seen on brochure style sites, where there are only a handful of pages. For larger sites with a lot more pages, the navigation flow and content findability gets unwieldy.

Index Page


A main page with subpages is probably the most commonly seen web site IA pattern. This consists of a main page (we know this more commonly as a "home page" or "front page"), which serves as a jump-off point for all the other pages. The sub-pages have equal importance within the hierarchy.

Strict Hierarchy Pattern


Some websites use a strict hierarchy of pages for their information design. On these sites, there will be an index page that links to sub-pages. Each sub-page (parent page) has its own subpages (child pages). In this pattern, child pages are only linked from its parent page.

Co-Existing Hierarchies Pattern


As an alternative to the strict hierarchy, there is also the option of co-existing hierarchies. There are still parent and child pages, but in this case, child pages may be accessible from multiple parent pages/higher-level pages. This works well if there’s a lot of overlapping information on your site.

Best Practices for Information Architecture Design

There are a number of things you need to remember when designing the information architecture of your site. Most importantly, you need to keep the user experience at the forefront when making choices about how best to present and organize the content on your site.

Don’t Design Based on Your Own Preferences

You are not your user. As a designer, you have to remember that site visitors won’t have the same preferences as you. Think about who a "site user" really is and what they would want from the site.

Research User Needs

Researching what your users need and want is one of the most important steps in creating an effective information architecture. There are a number of ways to research user needs. You could get feedback through interviews, surveys, user side testing, and other usability testing methods prior to the site launch to see if users are able to navigate your site efficiently.

Once you know what your users actually need, rather than just your perception of what they need, you will be able to tailor your information architecture to best meet those needs.

Have a Clear Purpose

Every site should have a clear purpose, whether that’s to sell a product, inform people about a subject, provide entertainment, etc. Without a clear purpose, it is virtually impossible to create any kind of effective IA.

The way the information on a site is organized should be directly correlated to what the site’s purpose is. On a site where the end goal is to get visitors to purchase something, the content should be set up in such a way that it funnels visitors toward that goal. On a site that is meant to inform, the IA should lead people through the content in a way that one page builds on the last one.

You may have sub-goals within a site, requiring you to have subsets of content with different goals. That is fine, as long as you understand how each piece of content fits in relation to the goals of a site.

Use Personas

Creating personas, a hypothetical narrative of your various web site users, is another great way to figure out how best to structure the site’s content.

In its very basic form, developing personas is simply figuring out the different types of visitors to your site and then creating "real" people that fit into each of those categories. Then throughout the design process, use the people you have profiled as your basis for designing and testing the site’s IA.

Keep Site Goals in Mind

It is important that you keep the site’s goals in mind while you’re structuring content. Pick the right IA pattern for those goals. Use goals to justify why the information structure should be the way you designed it.

Be Consistent

Consistency is central to exemplary information architectures. If eight of your nine informational pages are listed in a section, why wouldn’t you also include the ninth page there? Users expect consistency.

The same goes for how information is structured on each page. Pick a pattern and stick to it. If you deviate from that pattern, make sure you have a very good reason to do so; and make the deviation is consistent in similar cases. Inconsistencies have a tendency to confuse visitors.

Tomorrow, I am going to describe methods and techniques for information architecture design.
