Thank you for the thoughtful response. While at first I stumble over your
not answering my question, patience lead me to more carefully consider your
The SW approach is significantly different than I am used to in a ‘dumb
steal’ (DS) engineering environment. It would be a huge step for just my
company of 200 users to be swayed be one individual to change their
fundamental practices; but I am open to great challenges.
The differences in the two engineering types (SW & DS) are not that great
and the tools and artifacts are only abstractly equivalent. Still, my
fundamental functional challenge is the size of the repository. Each time
a repository transaction occurs, work would stop due to the large size (100
GB). So I wonder if there is some way to segment or fragment a repository
so an artifact that needs to be worked can be pulled with only its minimum
set of related artifacts.
