  In the age of Large Programs and Big Data a key component in project planning
for ground-based astronomical observatories is understanding how to balance
users demands and telescope capabilities. In particular, future planning for
operations requires us to asses the impact of a complex set of parameters, such
as right ascension, instrument, and sky condition pressures over coming
semesters. Increased understanding of these parameters can provide: improved
scientific output, better management of user expectations, more accurate
advertised/allocated time under a Call for Proposals, and improved scheduling
for instrumental commissioning and engineering work. We present ongoing efforts
by staff at the James Clerk Maxwell Telescope (JCMT) to build a tool to provide
automated completion forecasting of Large Programs undertaken at this
telescope, which make up 50% of the observing time available at the JCMT.
