## Who this is for

Anyone about to specify, buy or run a traceability system, whether or not they
have an ERP already.

## What you will be able to do

Split any inventory workflow into receiving, processing and dispatching, and say
for each stage what carries identity, what measures quantity, and what supplies
context.

## Lessons

1. [Identity](https://iotready.com/academy/traceability-foundations/identity.md) (12 min): What the thing is, read by a machine rather than typed by a person.
2. [Quantity](https://iotready.com/academy/traceability-foundations/quantity.md) (15 min): How much there is, measured by a device instead of estimated by a person.
3. [Context](https://iotready.com/academy/traceability-foundations/context.md) (18 min): Where in the workflow the capture happened, and what it should be matched against.
