It’s something to do a Google search for “design time at run time” (in qoutes) you’ll get:
…. design time. At run time …. …. design time — at run time….
…. design time, at run time…. …. design time; at run time …..
Where all of these results (the vast majority) aren’t talking about design time at run time. They are not joining design time to/with run time, but are separating or contrasting the two.
Searching for “Development at Run time” yields similarly coupled-for-contrast results.
“Live Development” comes close to meaning “Design time at Run time”. Live development requires that run time must be capable of design, or at least “Development at Run time”.
Search for “Collaborative Development’ and what a different story. If you have a BS detector, it will peg with over 9 million Google search results – brimming with BS. Some companies think that revision control constitutes development collaboration.
True run time for “Live Development” will also be “Collaborative Design time”.
