While not one of the eight steps of application development, using projects is an efficient way to organize your definitions as you develop and configure your application. A project keeps track of all definition types as a simple list of definition names; the definitions are not stored in the project. Development definitions exist outside of the project in your PeopleSoft database.
You are not required to use projects in PeopleSoft Application Designer; and you can create and edit individual definitions without associating them with a project. However, using projects can help you:
Organize related definitions.
Understand relationships among definitions.
Coordinate the work of several developers.
Streamline upgrade tasks.
Search for fields or records.
Access related definitions easily.
