Mechanics
A concise choice for the practical way a system functions.
Example: The course explains the mechanics of the electoral system.
Mechanism
Best for the process or means by which something produces an effect.
Example: Researchers are studying the mechanism behind the reaction.
Internal processes

Operations
Fits the activities through which an organization or system functions day to day.
Example: She learned the operations of the distribution centre.
Processes

Example: He became familiar with the machinery of government.
Architecture
Best for the underlying structure of software, systems, or organizations.
Example: The document describes the architecture of the platform.
Infrastructure
Refers to the underlying systems and resources that support operation rather than the processes themselves.
Example: The outage exposed weaknesses in the service infrastructure.
Nuts and bolts
An informal phrase for the practical details of how something works.
Example: The workshop covers the nuts and bolts of grant applications.
Behind-the-scenes processes

Example: The documentary shows the behind-the-scenes processes of live television.
Internal structure
Fits the arrangement of parts within an organization or system.
Example: The merger changed the internal structure of the department.
System logic
Useful for software, rules, or decision systems where logic drives behavior.
Example: The developer explained the system logic behind the automated alerts.
Underlying processes
Emphasizes less visible processes that produce an observable result.
Example: The study focuses on the underlying processes involved in memory.
How it works
The plainest alternative when technical wording is unnecessary.
Example: The guide gives a simple explanation of how it works.
