I need to create a nice pretty cartoon meme for this, but until that happens, this is an accurate comparrison between consumer-grade, enterprise-grade and telco-grade software. Recent AI developments have granted me with the wonderful ability to just magic an accompanying cartoon meme for this into existence. What a time to be alive!
Consumer Grade Software
Supplied as a download from the Internet, on a CD-ROM / DVD or a USB flash drive. Run the installer program, follow the on-screen install wizard instructions, et voila! Your software is installed and ready to use.
Enterprise Grade Software
The vendor sends an engineer on site with the software, who manually installs and configures the software on your behalf as there is no installation wizard and no installation instructions.
Telco Grade Software
The vendor sends three developers on site for a month who finish writing the software directly on your production infastructure. The software is custom written to only ever work in your environment and cannot be replicated without inviting the software developers back on site again.
