前言

我在上周的DX分享介绍中，提到过DX的核心就是面向package（包包）的开发模式。同学要像更快的上手DX，就一定要掌握 Package Development Model 。

今天为各位开始学DX的同学带来的就是Trailhead 中
Package Development Model 这个module 的导读。希望能帮助大家快速掌握这一DX的核心概念。

包开发的好处：

• Improving team development and collaboration.
• Modular development process with specification of dependencies among packages.
• Versioning to help with change management
• Facilitating automated testing and continuous integration.
• Making the release cycle more efficient and agile.
• Improved version control system (VCS) synchronization through change-tracking of Setup features
• More fine-grained visibility and clarity into the change management of your production org

这章主要需要理解包开发是如果提供灵活性的，相对于原来的基于Org的开发模式。
