Reflection

The final product is quite different from what I initially planed to have. I think one of the reasons is that during the process of documenting and analyzing my design, I realized what features are more important in demonstrating the bot's functionality and usability. Those are ones that deserve more effort. 

When integrating the bot with Slack App, there were options in using some builtin interactive interfaces provided by Slack. It was not that useful as it turned out none of the options fit well with my need. I think when designing a product with zero UI, it is important to think about what end points it is designed for. Different platform provides APIs differently, and that could impact on users' experience with the bot.

Improvement 

• Making the response more natural and attractive, such as providing images and/or suggestions
  
• Allow customers to order via slack 
  
• Providing more control for employees on editing categories / orders
