Chatbots in HR: Improving the Employee Experience

chatbotsinhr

After months of trial and error in building my chatbot prototypes, I finally finished my thesis for my master’s in Digital Management from Hyper Island, titled “Chatbots in HR: Improving the Employee Experience.”

What have I found?

  1. There is currently a lot of excitement and hype around chatbots that outstrips what chatbots can actually do right now
  2. Nevertheless, due to this recent surge of interest in chatbots, the developments in the industry are moving at a extremely rapid pace, with different chatbot products being built every day, in different industry sectors. Features and functions are being added and improved on at lightning pace
  3. Based on the testing of the chatbot prototype that I built for this thesis, there is a lot of potential in using chatbots in HR to improve the employee experience.
  4. Chatbots can free up time from the HR team, and in the long run, even help the HR function to move up the value chain
  5. If designed well, HR chatbots can create significant cost savings due to time saved in completing HR tasks (by employees) and answering queries (by HR team)
  6. In addition to providing friendly, instant information for employees, other areas of value-add for chatbots in improving the employee experience could lie in:
    • Helping employees to avoid embarrassment, or maintain their personal reputation, when they need to ask certain types of questions
    • Providing anonymity when employees want to read up on sensitive employee/company policies
  7. The most important issues that need to be resolved to make a customised chatbot for employees is the back-end integration with HR enterprise software as well as clear parameters over employee privacy and data collection. Some enterprise software vendors have partnered chatbot developers to create solutions for their software
  8. However, even without customisation, chatbots can still provide significant value in generic information services
  9. As use of technology increases in HR, HR leaders need to review the skillsets required in their HR team to enable the function to thrive in a new digital age

I built a bit of bot!

I want to order screenshot

After a frustrating afternoon, I finally made a personal breakthrough.

I built a bit of bot!

I tried building a chatbot from scratch on my own using DIY blog posts as guides, but it was too hard because I don’t have programming knowledge, and those instructions start with setting up a server, when I was raring to have a go at building the bot itself.

So after hours of trying today, I decided to take a different approach and take a shot at using a chatbot toolkit. I chose to use wit.ai as it was recommended by a friend, and also the fact that Facebook bought it.

Following instructions from the wit.ai starter guide, I managed to write a simple yes-no response. On top of that, I also “trained” the bot to respond to variations of yes/no, such as “yeah”, “yup”, “nope”; similar to how a person might respond over WhatsApp or FB Messenger. This is the most basic of basics, but looking at where I started just a few weeks ago, with my fears and concerns, this is really a leap forward.

So here it is, a screencast of my efforts today:

 

Chatbots: The Basics

Library

* I will be continually adding onto this blog post periodically

What is a Chatbot?

  • A chatbot is a service, powered by rules and sometimes artificial intelligence, that you interact with via a chat interface. (Schlicht, 2016)
  • Automated computer program that simulates online conversations with people to answer questions or perform tasks. (Knowledge@Wharton, 2016)
  • A chatbot system is a software program that interacts with users using natural language. Different terms have been used for a chatbot such as: machine conversation system, virtual agent, dialogue system, and chatterbot. The purpose of a chatbot system is to simulate a human conversation; the chatbot architecture integrates a language model and computational algorithms to emulate informal chat communication between a human user and a computer using natural language (Shawar & Atwell, 2007)

The opportunity for, and discussion around, Chatbots

  • People are using messenger apps, where chatbots reside, more than they are using social networks. (BI Intelligence, 2016)
  • Opportunity to reduce costs for companies. The chatbots envisioned by the tech industry combine artificial intelligence with voice recognition that relies on the way humans naturally speak. The goal is to create a situation where customers feel they are communicating with another human, rather than a piece of highly intelligent software, and in an environment that calls for little to no human operator intervention (Knowledge@Wharton, 2016). Indeed, research firm Gartner sees 33% of all customer service interactions as still needing a human intermediary by 2017,(Gartner.com, 2015) down from nearly 60% in 2014
  • In general, the aim of chatbot designers should be: to build tools that
    help people, facilitate their work, and their interaction with computers using natural
    language; but not to replace the human role totally, or imitate human conversation perfectly (Shawar & Atwell, 2007)
  • Bots are the beginning of micro apps on the backs of massive platforms which will lead to more focus and reach for startups and more delighted users (Batalion, 2015)
    • Spend less time in development, E.g. by building a microapp on FB Messenger allows you to build one experience (and do away with writing for different mobile phone sizes, or OS) and access FB user rich profiles instantly
    • Able to leverage richer UIs and multiple SaaS products to process input and focus more time on creating just enough of an experience to delight users
  • Attracts users to stay within the platform eco-system where the chatbot resides – messaging is now the new platform. (Newman, 2016; Bayerque, 2016; Raziano, 2016)
  • Increasing friction in getting consumers to download and use an app and quite costly as cost-per-install and paid acquisition marketing are increasing – the average global mobile user has = ~33 apps installed on his or her device and 12 apps used daily. 80% of the average global mobile user’s time is spent on 3 apps (Raziano, 2016)

Challenges surrounding chatbots

  • Hype: There is so much hype around the potential of chatbots, that the general public’s expectations of what chatbots can do will exceed the reality of what they can actually do (Hobson, 2016). The reality also is that not every bot needs to be sophisticated, and it will depend on the objective / outcome that the chatbot is built for. If it is meant as an informational service, there is very little point in building a bot to conduct a conversation with a user, when the bot is meant to be transaction-based
  • Developing a chatbot MVP (Minimum Viable Product): Software companies are used to developing a MVP, or a minimum standard version of the product that consumers would be willing to buy, to test in the market. However, for a good user experience, the product will likely need to have more accurate natural language processing and information before a MVP can be developed, which may mean that chatbots could require more capital than a traditional web or mobile app, where good frameworks are more commonly available (May, 2016)

What do consumers want in chatbots?

Based on a survey of 1,000 consumers in the UK in May 2016, the top perceived benefits of chatbots (MyClever Agency, 2016) was getting instant response and quick answers to simple questions. Interestingly, friendliness and approachability was not an important benefit for consumers, which indicates that customers want bots to enable efficient and accessible transactions.

Barriers to chatbot adoption by consumers

Supporting that view is consumers’ feedback on barriers to chatbot usage, and their biggest concern was that chatbots would not understand their questions. Chatbots that were incapable of friendly ‘chat’ was not a barrier at all for respondents.

Types of Chatbots

  • Rule-based 
    • Only responds to very specific commands. If you say the wrong thing, it doesn’t know what you mean. Only as smart as you program it to be  (Schlicht, 2016)
  • Machine-learning
    • Understands language, not just commands. Gets continuously smarter as it learns from the conversations it has with people (Schlicht, 2016)

Who’s trying to attract/facilitate Chatbot developers? 

  • Google with Allo (Fulay and Adan, 2016), incorporating
    • Smart Reply – respond to messages without typing a single word. Learns over time and will show suggestions that are in the user’s style
    • Google Assistant – help to find information and complete tasks, e.g. book a dinner reservation, flight status
  • Facebook with bots for Messenger (Marcus, 2016Facebook Developers, 2016)
    • Send / Receive API – ability to send and receive text, images, and rich bubbles with Call To Actions (CTAs)
    • Generic Message Templates – structured messages with CTAs, horizontal scroll, urls, and postbacks.
    • Natural Language Assistanceusing the wit.ai Bot Engine to create conversational bots that can automatically chat with users
    • Tools to enable discovery of bots – plugins for websites, usernames and Messenger Codes, prominent search surface in Messenger, ability for Facebook News Feed ads to enable the opening of threads on Messenger, a new customer matching feature will allow messages that are usually sent through SMS to be sent on Messenger
  • Microsoft with Microsoft Bot Framework, a set of tools to help developers build artificial intelligence bots (Knowledge@Wharton, 2016), comprising (Foley, 2016):
  • Kore Bots Platform, that includes (Kore, 2016)
    • A Natural Language Processing engine 
    • Enterprise Administration and Security
    • Kore Bot Store – pre-loaded with more than 130+ ready-to-use enterprise and personal bots that perform thousands of tasks. Enterprises can also select, customize and create an approved collection of bots for their organization’s own private enterprise bot store.

History and development of Chatbots

  • Eliza, the first chatterbot ever coded, was then invented in 1966 by Joseph Weizenbaum. Eliza, using only 200 lines of code, imitated the language of a therapist. He intended ELIZA to be a  parody of human conversation, yet suddenly users were confiding their deepest thoughts in Eliza
  • What was made clear from these early inventions was that humans have a desire to communicate with technology in the same manner that we communicate with each other, but we simply lacked the technological knowledge for it to become a reality at that time

Applications of Chatbots

Questions to ask when considering developing a Chatbot  (Knowledge@Wharton, 2016; Jalali, 2016

  • Strategic
    • How do they impact the customer experience/interaction?
    • How do they fit with the positioning of the brand?
    • How relevant is it to the business?
    • Have we evaluated the resources that need to be allocated?
    • What will the success metrics look like?
  • User Acquisition
    • How will users discover the bot?
  • User Experience / Functionality
    • How well do they work?
    • What will the UX interface be like?
    • How frequent will your bot updates be?
    • How will you create a “Minimum Viable Onboarding (MVO)”, i.e. show users how to interact with the bot and understand what the bot is good at, to set expectations on how “human” the bot will be?

Tips for Building Chatbots (Schlicht, 2016)

  1. Decide what problem your chatbot is going to solve
  2. Choose which platform your bot will live on (Facebook, Slack, etc)
  3. Set up a server to run your bot from
  4. Choose which service you will use to build your bot

Jumping in feet first into bots

Coding

This blog was created as a requirement for my part time masters course in digital media management at Hyper Island Singapore .

Now that I’m embarking on my final project, I’m re-purposing this blog to document my learnings and observations on my project, which revolves around the research question “How might I better understand, and test, the potential of chatbots and its application in the HR function?”

Why chatbots? Well, why not?

Initially I had a lot of hesitation on embarking on this (I still do), because I have no technical knowledge, but I’m fortunate to have friends who do have that background, and have pointed to resources and toolkits that will help me build a prototype, should I need to.

In the working world, where it may sometimes be difficult to launch projects that you are uncertain about, this is the best platform to try something new and unknown. After all, it affects only me, if I fail. And even if I fail, what is the worst that can happen? A delayed project submission? Not getting my masters? (although I’m going to try my best to not let that happen).

The experience I gain would be far more valuable than a piece of paper. So, wish me luck and success on this journey.
