Definition
The process of installing a Salesforce package (from AppExchange or a URL) into an org, which deploys the package's metadata components and makes its functionality available to users based on configured permissions.
In plain English
“Package Installation is the process of installing a Salesforce package (from AppExchange or a URL) into an org. The installation deploys all the package's metadata components and makes its functionality available to users, with permissions configured during the installation flow.”
Worked example
Brackenwood Capital decides to use a popular AppExchange compliance package. The admin clicks the package's AppExchange listing → Get It Now → Install in Production. The Package Installation flow asks her to choose user-permission level (Install for All Users, Install for Admins Only, or Install for Specific Profiles), shows the components being deployed (12 custom objects, 30 fields, 8 Apex classes, 4 Lightning pages), and runs the install. The package's components appear in the org with the publisher's namespace prefix; users with the right permission set see new tabs and functionality. Package Installation is the front-end of every AppExchange consumption.
Why Package Installation matters
Package Installation is the process of installing a Salesforce package (from AppExchange or a URL) into an org, which deploys the package's metadata components and makes its functionality available to users based on configured permissions. The installation flow typically includes selecting which user profiles get access, accepting terms, and confirming the deployment. After installation, the package's components appear in the target org and users can start using them.
Installation is a careful operation because installed packages add to the target org's metadata and may have implications for performance, storage, and existing customizations. Mature orgs test package installations in sandboxes before production, evaluate dependencies, and plan the rollout to users. AppExchange-listed packages have gone through Salesforce security review, which provides some confidence in code quality, but customers still need to validate the package fits their needs.
How organizations use Package Installation
Tests every AppExchange package installation in a sandbox first, validating functionality and impact before production deployment.
Plans package installations as proper deployments with rollback plans, even for packages from trusted vendors.
Treats package selection as an architecture decision, evaluating multiple options before installing.
