Design a persona's process once. When someone submits a form, is imported or replies to outreach, the whole plan is cloned for them with dates and owners.
A journey is an ordered pipeline of tasks with owners and due dates. Attach it to a persona and every matching contact gets their own copy.
Rules at brand level: a form is submitted, a stage changes, a task completes. Then send an email, create a task, set a field or notify someone.
Planbook boards hold every plan; My Tasks shows each person their day. Comments, @mentions and attachments live on the task.
Templates cover onboarding, nurture and follow-up. Edit one, or start from a blank rule.
Then let every lead run through it.
