Reminds me of a software development firm I visited recently.

The difference being that they had not just a roadmap
but also a summary on the wall:
* of what was currently being coded, (and who was tasked)
* what was ticked off as finalized for the next release,
* what was being siderailed due to issues,
* and what the next release date looked like in view of current code.

Simply having a blurrrrry roadmap indicates
a desire to sell something with no real substance behind the plan,
something like the Turing phone comes to mind.


What KDE are doing with Plasma Mobile appears excellent,

see where they are going here:

This PM 1.0 appears to be a real effort.
