I've seen lots of great messages about sharing existing templates, principles and ideas on here, and wanted to contribute one of the topics I talk with internal folks on kick off calls and ask if other folks have principles / presentations / handouts they're able to share.
Deciding if something, should or shouldn't be eSourcing comes down to three principles we're all most likely already using every day
Can we clearly specify it?
Is there competition in the marketplace?
Is it attractive to suppliers?
If the answers are yes, then no matter if it's consulting, website development, or boxes with bar codes, we can eSource it.
Building and publishing a project is a team effort, here are the Five Essentials for Successful eSourcing that I've developed
Correct Points of Contact with the supplier.
Clearly written Requirements / Scope or Schedule of Work
Clearly written questions for suppliers
Correctly completed eSourcing template
It's not rocket science, but it's in a handy, easy to use and digest format.
