From my 10 years of experience working with SSIS these are some factors to consider while working on SSIS projects:

  1. Plan your SSIS project: Before starting your SSIS project, take the time to plan out your data flows, package dependencies, and overall project architecture. This will help ensure that your project is well-designed and scalable.
  2. Make use of control flow tasks: Control flow tasks are the backbone of SSIS, and they allow you to perform a variety of operations, such as executing SQL statements, sending email notifications, and executing packages. Make use of control flow tasks to build a flexible and reusable data flow.
  3. Use variables: Variables are a key component of SSIS, and they allow you to store and manage values throughout your package. Use variables to store values that can be used by multiple tasks or components, such as connection strings, file paths, and parameters.
  4. Make use of data flow transformations: Data flow transformations are used to manipulate and transform data as it is being transferred from one location to another. Common transformations include sorting, merging, and splitting data.
  5. Use data flow components wisely: There are a number of data flow components available in SSIS, and it is important to use them wisely. For example, use a lookup component instead of a join to improve performance and reduce resource usage.
  6. Make use of event handlers: Event handlers are a powerful feature in SSIS that allow you to handle specific events that occur during the execution of your package. Use event handlers to send notifications, write log messages, and perform custom actions in response to specific events.
  7. Monitor and troubleshoot errors: SSIS packages can sometimes fail, and it is important to have a plan in place for monitoring and troubleshooting errors. Use the SSIS logs, event handlers, and breakpoints to identify and resolve errors in your packages.
  8. Make use of the SSIS catalog: The SSIS catalog is a centralized repository that is used to store, manage, and execute SSIS packages. Use the SSIS catalog to organize your packages, manage security, and monitor execution.
  9. Make use of parameters: Parameters are a way to pass values into your packages, and they can be used to make your packages more flexible and reusable. Use parameters to pass values such as connection strings, file paths, and other dynamic values into your packages.
  10. Test and validate your packages: Before deploying your packages to a production environment, it is important to thoroughly test and validate them. Use the debugging features, event handlers, and logging capabilities of SSIS to ensure that your packages are working as expected.
