Phase 2: Design & Implement
Design Question
-
How will you craft a simple purpose?
- The chatbot should state its purpose so that it’s clear what it can or can’t do or what tasks it can support. If there is a long list of capabilities, the message may be too long. The purpose should be stated clearly and concisely.
Examples
-
State the purpose at the beginning of the conversation: “I can help you with your application.”
-
Repeat the chatbot purpose when the user doesn’t input something for a while: “I can help with tasks like checking your application status or renewing your status.”
-
Put the purpose at the top of the window: “Interactive chatbot for filing applications and status checks. For a full list of capabilities, click here.”
-
Repeat the chatbot purpose when the chatbot detects a miscomprehension: “I’m not sure I can do that - I can help you file a new application or check the status of an existing application.”
Phase 3: Test & Evaluate
Self Check
- Does the chatbot clearly state its purpose?
Ask the User
-
What is the purpose of this chatbot?
- This question is objective; compare the user’s response to an ideal value. This question should be asked post-study.
