Development Roadmap
===================

To assist the development team and help TESP users where we see TESP
developing, the TESP development team has created a development roadmap.
The roadmap is expressed as a git graph where “main” is used to
represent completed work and each area of activity is shown as a named
branch in the graph. (Note that the names of the branches in this
roadmap do not necessarily correspond to the branches in the `TESP
Github repository <https://github.com/pnnl/tesp>`__.) As of summer of
2025, the TESP team is moving to planning on a quarterly basis with key
deliverables or milestones on this cadence. The deadline for any task is
shown by a merge back into the “main” branch prior to a
fiscal-year-and-quarter end-date (*e.g.* “Dec 31, 2025”). Note that
because this is a git graph and not a Gantt chart, we show only when the
activity is completed (the quarter it is due) and not when it began.

The activities for the upcoming quarters are most likely to be accurate
with the fidelity of the plan decreasing the further into the future of
the planned activities. Even for activities planned in the near future,
circumstances and changing priorities of the `Transactive Systems
Program <https://www.pnnl.gov/projects/transactive-systems-program>`__
as a whole may change planned activities even in the near future. Which
is to say, the published roadmap reflects the TESP’s development team’s
priorities as of the latest revision but nothing is ever set in stone.
