Expressing Control and Responsibility in English

Control, Manage, Handle, Coordinate, Orchestrate: What's the Difference?

1. TO COORDINATE

Definition: [transitive] To organize an activity so that the people or things involved work well together and achieve a good result.

In IT, coordinate often refers to making different components, processes, services, or people work together correctly.

Examples

• transaction-type="JTA" indicates that transactions are coordinated by the container.
• The framework coordinates communication between the different services.
• The transaction manager coordinates the operations performed by multiple resources.
• The development team coordinated the deployment of the new application.
• The operating system coordinates access to shared resources.

Common patterns

• to coordinate an activity
• to coordinate the work of different teams
• to coordinate communication between components
• to coordinate the execution of several tasks

2. TO CONTROL

Definition: [transitive] To have power over something or someone, or to determine how something behaves, operates, or is done.

In IT, control often means determining or restricting the behavior, operation, appearance, or access of a system or component.

Examples

• An HTML page can use more than one CSS style sheet. For example, some authors use one CSS file to control the presentation (such as fonts and colors) and a second to control the layout.
• The administrator can control which users have access to the application.
• The operating system controls how processes use system resources.
• The programmer can control the behavior of a component through its configuration.
• The application uses a flag to control whether a particular feature is enabled.
• Access control mechanisms determine who can read or modify a file.

Common patterns

• to control access to a resource
• to control the behavior of a component
• to control how something works
• to control the flow of execution
• to control the appearance of a web page

3. TO HANDLE

Definition: [transitive] To deal with a situation, task, problem, or person; or to process, manage, or respond to something.

In IT, handle is particularly common when describing how a component deals with input, events, errors, requests, or specific tasks.

Examples

• An exception handler is responsible for handling exceptions that occur during program execution.
• The server handles incoming HTTP requests.
• The application handles user input and validates the submitted data.
• The event listener handles the click event when the user presses a button.
• The database driver handles communication between the application and the database.
• The method handles errors that may occur while reading a file.
• The framework handles dependency injection automatically.
• This class handles authentication and authorization for incoming requests.

Common patterns

• to handle an exception
• to handle an error
• to handle a request
• to handle user input
• to handle an event
• to handle communication between components
• to handle a particular situation

Other common meanings outside IT

• She handles difficult situations very well. — She deals with them effectively.
• He handles customer complaints. — He deals with customer complaints.
• This box is difficult to handle. — It is difficult to lift, carry, or move.

4. TO MANAGE

Definition: [transitive] To take responsibility for, direct, organize, or control something or someone; to ensure that a task, system, or activity operates as intended.

In IT, manage often implies responsibility for the operation, organization, configuration, or lifecycle of a resource or process.

Examples

• To collaborate on a Git project, you need to know how to manage your remote repositories.
• JavaBeans can manage the flow of data between application clients and server-side components.
• Database management systems (DBMSs) provide utilities that help database administrators manage databases.
• Integrated development environments (IDEs) help developers manage the entire development cycle within a single application.
• Development tools provide the ability to manage Java EE components through a graphical interface.
• How a Java component manages its state can have implications for its performance.
• The Twitter account of the President of the European Parliament is managed by a media team.
• CDI changes how class dependencies are managed. Without CDI, dependencies may be managed programmatically by creating instances with the new keyword and passing them to other objects. With CDI, the container manages the creation and injection of dependencies into injection points marked with the @Inject annotation.

Examples outside IT

• He was asked to manage a new department.
• Managing a football team is harder than you think.
• The company had been very badly managed.

Common patterns

• to manage a database
• to manage resources
• to manage dependencies
• to manage a project
• to manage a team
• to manage the lifecycle of an object
• to manage memory
• to manage user accounts

5. TO ORCHESTRATE /ˈɔːrkɪstreɪt/

Definition: [transitive] To carefully plan, organize, and coordinate a complex activity or series of actions so that its different parts work together.

In IT, orchestrate often describes coordinating multiple components, services, tasks, or operations according to a defined workflow.

Unlike coordinate, which emphasizes making different parts work together, orchestrate often suggests directing a more complex sequence of actions.

Examples

• The central API responsible for orchestrating entity operations is the javax.persistence.EntityManager.
• Kubernetes orchestrates containers across a cluster of machines.
• The workflow engine orchestrates the execution of multiple tasks.
• The application orchestrates calls to several microservices to complete a user request.
• The orchestration layer coordinates the different services involved in processing a transaction.
• The system automatically orchestrates the deployment of applications across multiple servers.

Common patterns

• to orchestrate a workflow
• to orchestrate a series of operations
• to orchestrate multiple services
• to orchestrate container deployment
• to orchestrate communication between components
• to orchestrate a complex process

Note: In general English, orchestrate can also mean to arrange an event or situation carefully, sometimes secretly. In technical English, however, it usually refers to the coordination of complex systems or processes.

6. Understanding the differences

These verbs overlap, and technical authors do not always use them consistently. Nevertheless, the following distinctions are useful when learning English through IT books.

Coordinate

Make different parts work together.

The transaction manager coordinates the participating resources.

Control

Determine or restrict behavior.

The configuration controls the application's behavior.

Handle

Deal with or process a particular input, task, or situation.

The method handles the exception.

Manage

Take responsibility for the operation or organization of something.

The container manages object creation and dependencies.

Orchestrate

Direct a complex workflow or sequence of coordinated actions.

The workflow engine orchestrates the execution of multiple tasks.

7. A quick comparison

Verb	Main idea	Typical IT objects
Coordinate	Make things work together	Teams, transactions, components
Control	Determine behavior or access	Execution, access, layout, resources
Handle	Deal with or process something	Events, errors, requests, input
Manage	Take responsibility for something	Resources, databases, state, dependencies
Orchestrate	Direct a complex sequence of actions	Workflows, services, containers, deployments

8. A useful learning tip

Pay attention to the nouns that commonly follow each verb. Learning these combinations, called collocations, will help you understand technical documentation and write more naturally.

For example:

• Handle an exception, an event, a request, an error.
• Manage resources, dependencies, state, a database.
• Control access, behavior, execution, the layout.
• Coordinate activities, transactions, communication, teams.
• Orchestrate workflows, services, operations, deployments.

These are common tendencies, not strict rules. For example, a framework can handle, manage, or control a process depending on what the author wants to emphasize.
