Package Development model in Salesforce


Salesforce, being a robust platform for building custom applications, offers various methodologies for developing and distributing applications. One such prominent approach is the Package Development Model, which streamlines the process of packaging and distributing customizations across Salesforce environments. 

In this blog, we'll delve into the fundamentals of the Package Development Model in Salesforce, its benefits, and best practices for effective package development.

Understanding the Package Development Model:

The Package Development Model in Salesforce revolves around the concept of creating modular packages containing customizations such as metadata, Apex code, Lightning components, and more.

These packages can be easily installed in different Salesforce environments, allowing developers to distribute their solutions efficiently. 

There are two primary types of packages under this model: Managed Packages and Unmanaged Packages.

Managed Packages:

Managed Packages are fully version-controlled and provide a structured way to distribute applications. They encapsulate customizations in a controlled environment, ensuring seamless upgrades and dependency management. Managed Packages offer features like namespaces for unique identification, upgradability, and security controls.

Unmanaged Packages:

Unmanaged Packages, on the other hand, are more flexible and suitable for simpler deployments or sharing code snippets. Unlike Managed Packages, Unmanaged Packages do not enforce versioning or dependency management, making them less suitable for complex applications. 

However, they are convenient for sharing configurations and customizations among different orgs.

Benefits of the Package Development Model:

  • Modularity and Reusability: Packages allow developers to modularize their customizations, promoting code reuse and maintainability across projects.
  • Version Control and Upgradability: Managed Packages offer version control capabilities, enabling developers to release updates and patches efficiently while ensuring backward compatibility.
  • Dependency Management: Managed Packages streamline dependency management by encapsulating customizations and their dependencies, reducing the risk of conflicts during deployments.
  • Security and IP Protection: Managed Packages provide namespace protection, safeguarding intellectual property and preventing conflicts with other applications.
  • Efficient Distribution: The Package Development Model simplifies the distribution of customizations, enabling developers to share their solutions with customers, partners, or the broader Salesforce community seamlessly.

Best Practices for Package Development:

  • Granular Packaging: Break down customizations into smaller, modular packages to promote reusability and maintainability.
  • Versioning: Adhere to a consistent versioning strategy for Managed Packages to ensure smooth upgrades and compatibility.
  • Dependency Management: Clearly define dependencies between components within the package and external dependencies to avoid deployment issues.
  • Testing and Quality Assurance: Thoroughly test packages in sandbox environments before releasing them to production to identify and address any issues.
  • Documentation: Provide comprehensive documentation for packages, including installation instructions, release notes, and any prerequisites.
  • Security Considerations: Implement proper security measures, such as using Shield Platform Encryption or configuring appropriate sharing settings, to protect sensitive data in packages.


In a nutshell, the package development model is focused on packages be they managed or unmanaged.

The Package Development Model in Salesforce offers a structured approach to building, distributing, and managing customizations across Salesforce environments. 

By leveraging Managed and Unmanaged Packages, developers can streamline the deployment process, promote code reuse, and ensure scalability and maintainability of their applications. 

Embracing best practices in package development is essential for delivering high-quality solutions that meet the needs of stakeholders while adhering to security and compliance requirements.

In essence, mastering the Package Development Model empowers Salesforce developers to unleash the full potential of the platform and deliver innovative solutions that drive business success.
