A workload is a defined job that needs to get done, handed to agents instead of to a person with a tool.
Every workload has two parts:
When it comes up. The circumstance that creates the work: an event (a lead arrives, a competitor changes price), a schedule (every Monday, every month), or a standing need (the site must stay machine-readable).
What done looks like. The outcome in your terms, something you can inspect: the comparison is live and current, the lead has a next step, the report is in your inbox.
A workload is done and then kept done. The first pass builds it; after that, agents keep it true as circumstances change.
A workload is not a step. Research, drafting, and publishing are steps within a content marketing job. If you wouldn't ask for it on its own, it's a step.
A workload is made of workflows, the repeatable processes that need to run to do the job.
A Role is a set of workloads that together cover what one hire or one agency would do.
