Minimum Viable Product vs. Minimum Delightful Product:

For consumer products, SMB apps, software tools, hardware, retail, and other categories “viable” isn’t compelling. Using a merely viable product is like visiting someone in an intensive care unit. They’re alive, but not fun to spend time with.

And:

Unfortunately, all too often MVP becomes VCP (very crappy product). Ironically this comes from losing sight of a very core agile concept: when something is done it’s done. Put differently, if a feature is built it should work without problems. The feature may not include all the functionality you can imagine, but what it does include has to work well.
