  ObsMode is a yearly process which aims at preparing capabilities for future
ALMA Observing cycles. The process has been running for a number of years tied
to each ALMA observing cycle, with various leaderships. This document
specifically summarizes the ObsMode2020 process (April- October 2020) with a
new scheme led by the Joint ALMA Observatory. In the ObsMode2020 process, seven
capabilities are identified as high priority items, for which it was originally
aimed to be ready for Cycle 9. However, because of the observatory shutdown due
to the covid-19 pandemic, we were forced to delay the test plan by one year.
While no new data sets were obtained during the observatory shutdown,
verifications using the existing data allowed us to offer the 7m-array
polarization capability (in ACA standalone mode, single field) for Cycle 8
starting from October, 2021. In addition, subsystem readiness and policy-side
preparations for the phased array observing mode were improved for Cycle 8.
Other high priority items were decided to be carried over to the ObsMode2021
process.
