This page describes how to define and map the user journeys of your Google Chat app. A user journey is a set of actions and interactions between a user and a Chat app that helps the user achieve a goal. Define these journeys before building the Chat app to identify the following:
- When to provide error messages.
- When to suggest slash commands to help users use the Chat app.
- Where the user flow might be simplified.
Create a flowchart of all user journeys
Flowcharts are useful tools for both visualizing and thinking through all user Chat app interactions. If your Chat app works with other Google services, or services outside of Google, be sure to include these interactions too. Ideally, your flowchart depicts every possible interaction, or for more complicated workflows, a flowchart for every user journey.
The following flowchart shows the user journey for a Chat app that helps people manage their Google Calendar from Chat:
The preceding diagram shows the following steps of a user wanting to use a Chat app to check their Calendar:
A user adds the Chat app to a space.
The Chat app sends a welcome message that prompts the user to authorize access.
- If the user refuses to authorize access, the previous welcome message is resent.
- If the user agrees to authorize access, they click Sign in.
The user is asked to sign in from a dialog message.
- If the user is unable to sign in, an error message is sent asking the user to try signing in again.
- If the user is able to successfully sign in, an onboarding message is sent that describes how to use the Chat app.
The user types the
/checkCalendar
slash command to get today's schedule from Calendar.- If the Chat app is unable to retrieve the user's calendar, an error message is sent.
- If successful, the Chat app sends today's schedule in a card message.
Write user stories to guide your user journeys
A user story represents a user goal, and is written so that the user, task, and purpose of the story is clear. User stories are meant to be open-ended because there's usually more than one way to satisfy the requirements that they describe. User stories help you set paths for users to follow as they work with Chat app.
User stories have the following format: As a user, I want to do a task, so I can achieve a goal. In the previous example, the user story is: As a cross-functional worker, I want to check my calendar so I can collaborate on projects with others.
Most Chat apps have multiple user stories. For example, another user story for the example Chat app is: As a manager, I want to schedule a weekly meeting that includes all my direct reports, so we can collaborate on projects. For each user story, identify the users' journey for your Chat app and create a flowchart to identify all potential interactions with your Chat app.
Include a legend
To help others read your user journeys, include a legend that describes which shape represents which type of interaction. For example, identify a unique shape for user decision points, user input, successful and unsuccessful results from your Chat app, and any messages from the Chat app.
Account for all error scenarios
To ensure users never get stuck while working with your Chat app, include error scenarios in your user journey map. Define how the error occurs, write an actionable error message, and identify how the user might respond to the error in order to achieve their goal. For example, "Wrong username or password. Try signing in again."
Identify the messages your Chat app sends to users
Each interaction should end with a message from your
Chat app to the user, even if it's only a message
confirming that the Chat app successfully completed the
user's request. For example, "Welcome to the scheduling app. I can schedule,
reschedule, or remove events from your calendar. Take a look at today's schedule
by typing /checkCalendar
."
