My senior executive productivity for big projects is super charged with 3 interconnected Omni apps. OmniPlan to plan, map, monitor and update. OmniOutliner to track and identify progress accross multiple metrics. OmniFocus to drive daily focus and effort. In this combination, for me, these Omni apps genrate consistent results and deliver a clear return on my investment in time and money. Thank you The Omni Group.
