The document discusses the design patterns for embedded systems, emphasizing the augmentation of human roles through consultative tools that create custom models for specific issues. It highlights the importance of real-time data analysis facilitated by expert analysts, ensuring integrity and trust in the models used for decision-making. Decisions are made in a composite context, considering past similar decisions, while maintaining careful control over the system's functionality and data integrity.

1. Systems Design Patterns for Embedded DA

2. Ground Principle
Humans not replaced, but augmented

3. Purpose of Tool
Consultative DA Embedded DA
“Knobs for Nerds”
Create custom models
to meet particular issues
in the situation
!
“Lean Models”
Train against common
simple templates and
deploy
Bad idea to reuse

6. Workflow
Consultative DA Embedded DA
Facilitated through an
expert analyst
Real-time mediated by
system
Send out requests for data,
carefully review the data
received and plug into model for
analysis.
Distributed work across
roles and geographies.
System turns into a
storehouse of useful
information.

Quote: The executive team was able to trust our process
because we could show them our numbers in real-time, and the
assumptions behind them.

11. Composite Context
Consultative DA Embedded DA
Decisions are one-off
or unique.
Decisions are made
in the context of a
stream of similar
decisions.

e.g. Other similar
project decisions, or
a portfolio of related
decisions
