When you start constructing a plan, just typing in task after task, the Gantt chart shows all of the bars mashed up against the left edge of the chart, because you haven't entered any data to tell it that all those tasks couldn't be accomplished simultaneously. The only reason they would be scheduled at some other time is if they had prerequisite dependencies from some other task, or one or more of the assigned resources couldn't be allocated to the task at T=0. Those new tasks you added which don't have any resource assignments or dependencies could have started immediately at T=0, so that's when OmniPlan schedules them. This paragraph is the key to everything here. Resource availability is not taken into consideration, so resources may end up overutilized.' This means the task is placed at the very earliest time possible, taking into consideration start and end constraints, and dependencies on other tasks. Help: 'By default, new tasks are scheduled as early as constraints allow. They don't show any dependencies in the Gantt chart. I initially assigned a resource to them (me), but removed that and it makes no difference with the issue (see next). I created a task group (1.3.1.2.13) and three tasks within it. I'm sure this is a standard 'RTM' question I'm new to OP.
