Bot building system
None
None
Conceived about 6 years ago
We’ve been building bots before it was cool
Bot
IRC WoW bots Web Scrapers
Chatbots
Conversational Commerce
A bot pretends to be a human
Makes stuff happen
Emphasis on “Human” aspect
Wit.ai API.ai Motion.ai Microsoft Bot Framework Init.ai <Whatever>.ai
Can you <deliver> <my order> to <my work address> instead?
What to do when there’s no match?
Guess Bail out
AI + Human
Facebook M 70% required human
Leaky abstraction
Bots are Dead End of story
“Human”-like is a red herring
How vs What
Goal Scenario Guidance
Humanize later
Scenario
Workflow
Do X Do Y Do Z
Customer case: PeopleReady
Workforce matching
“Uber for Workers”
I’m a construction worker I’m free next Friday
I need 5 extra construction workers on site next Friday
Phone Decision Tree
“If you need X press 1”
IVR “Interactive Voice Response”
Step 1: Static Tree
Step 2-∞: Refinements Shortcuts A/B tests
Identify a person/role Reduce tree
Known pending request: top-level notification
Global shortcuts
Keywords, numbers, etc.
Bot-to-Bot IVR-to-IVR
Pass context
Session storage HTTP/SIP headers Forward DTMFs
Dumb Boring
Efficient Predictable Less frustrating
None
Workflow Builder Execution Services Operator Apps Reporting
Many competitors Not a winner-takes-all
Lessons Learned
1. Providers
Slack, Messenger, Telegram, Skype, Email, sms, HipChat, WeChat, LINE, etc
The more the better?
SMS Phone Email
No middle man apps Brand <=> Phone
2. Execution model
State Machine
State Machine as Data
Flow Tree => Data Structure Executor
State Machine as Code
Flow Tree => Data => Code
Separate Infrastructure Separate Deploys Separate Load
AWS Lambda
3. Steps are the key
if … else Choice 10-15
Smart Steps 100s
Phone Transfer
Transfer to X Backup number? Voicemail? Transcode?
Feature discovery
Higher quality Bots by default
Programmable steps
Flow => Step
Step = Logic + UI both programmable
Custom JS Step
4. Service Flows
Pick up the phone Identify a User Voice Choice …
Number Provisioning API Adapter Reporting Events Hide Secrets …
Service flows Global Events with ACL
5. Dogfooding
Everything is a bot
Admin tools Monitoring Reporting Billing
6. UI and Reporting Sell Platform retains
UI! So many capabilities!
“Can you set it up for us?”
Typical Customer: sets thing up once receives reports
7. Reporting!
SQL Server OLAP Direct access
Let customers play with the data
8. AWS Lambda
async (req, context) => { ... }
Node 4.3 (6!) Python Java
Use Large
1 request = 1 new process
Dynamo & Redis :) Mongo, SQL :(
Dynamo is amazing!
9. Voice
Voice is inherently hard!
Twilio Best API and DevTools Still hard :(
Larger customers need cheaper voice
TwiML Twilio SIP + Custom Voice Direct SIP-to-SIP
SIP + RTP
SIP Commands & Events Bi-directional
RTP - audio
Often Arcane practices
Huge Risk
Opens doors
10. Small things Big Impact
Haiti Earthquake SMS Fundraiser
Suicide Prevention Hotline
Washington DC city bot
Roadside assistance Match-making Marketing Customer support Sales
OneReach
