After witnessing the collateral damage of many software reuse projects (anyone remember "components"?), I came up with a different ruleset, useful for "compromising" with "software architects":

First, translate the data.

Second, divine a common format and share the data.

Third, create the libraries for this common format, to be reused amongst projects.

I have never reached #3 in my professional career. Sure, we wrote the libraries. But other teams, projects have never adopted before whole effort became moot.

So I kept my projects in tact and moving forward, while letting mgmt think they're doing something useful.
