OHIO is an acronym that stands for "Only Handle It Once", and it's a popular productivity strategy for managing email and tasks.
The idea is simple: when you touch something, like a task, an email, a note, then you deal with it right away instead of postponing the decision. If you open an email, either reply, delete, file, or schedule it.
You open an email, read it, then close it. Later you open it again, read it again, and still do nothing. Before you know it, you have touched the same message five times and still feel behind.
The OHIO (only handle it once) principle was popularized by financial executive Robert Pozen in his book Extreme Productivity. The Ohio Method is built upon the time management philosophies developed by early pioneers such as Ivy Lee and Alan Lakein.
When you encounter an email or task, immediately choose one:
- Reply: If it takes less than 2-3 minutes, do it now
- Delete: If it's not important, remove it immediately
- File: If you need it for reference, archive it
- Schedule: If it takes longer, add it to your calendar/task list
Important Modification - OHIO 2.0: Only proceed with OHIO if the task will take a short time, approximately less than three minutes. This is to make sure you don't get sidetracked too much from your real priorities.
Tackling your low-priority items immediately when you receive them prevents a backlog from developing, which wastes time and increases anxiety.
Most people check their inboxes several times per day, looking at the same list of unanswered emails, without doing anything about it. This is a waste of precious mental energy.
It enables someone with a heavy email load to process email 3-5 times per week and have better response times than a person who checks it 10x as much.

- Items needing research
- Anything taking more than 3 minutes
