MOSS 2007 Development Decision Matrix
Chris Johnson posted a great article on the options for conducting UI application development in MOSS 2007. Many of us conducting MOSS development have been through this exercise in deciding about how to conduct development. See his article here:
Here is his decision matrix for my own selfish ease of use.
|Single Site||Some Sites||Many Sites|
|Per site functionality||Smart Part||Smart Part or Web Part||Web Part|
|Single instance application||Smart Part||N/A||N/A|
|Site extension functionality||Web Part||Web Part||_Layouts application|
Thanks Chris for putting it into words for us.
