Extensibility strategy checklist

Define your extensibility strategy

Done?	Task
✓	Make sure that you only extend the solution when it empowers users or adds value to the business.
✓	Don't try to copy the same results as the legacy solution or the system you're replacing.
✓	Understand the platform capabilities and use them to simplify and optimize the process. Use the out-of-the-box features as much as possible.
✓	Check if there are any independent software development (ISV) organizations that can meet your needs before you decide to extend the solution. The AppSource marketplace has ISV-managed solutions that might replace the need for a custom solution.

Done?	Task
✓	Test how the extensions affect the user experience, responsiveness, performance, and cross-device behavior.
✓	Make sure that the extensions follow the security, privacy, and compliance requirements.
✓	Make sure that the extensions can handle high volume and peak seasons.
✓	Use ALM automated processes to build and deploy the extensions efficiently and quickly.
✓	Use only the documented supported techniques for code and customizations. Don't use deprecated features and techniques.
