By purpose
Writing a ringi for equipment purchases
Go beyond saying that equipment is old. Explain its effect on current work, the quantity needed, and what this purchase would not cover.
Explain why a purchase or replacement is needed
Describe verified problems such as fault symptoms, missing functionality or an insufficient number of units. Age alone does not explain the business impact; usage context helps. If the cause is unknown, do not claim that replacement will necessarily solve it.
Align item, quantity, unit price and total
- Separate required specifications from the reasons for choosing them.
- Check that quantity multiplied by unit price matches the total.
- Separate known costs for equipment, accessories, installation, delivery and disposal.
- State tax treatment and whether an amount is a formal quotation or an estimate.
Compare urgency and alternatives
Explain the business reason for the desired timing. Replacing broken equipment has a different urgency from buying for a future improvement. Keep desired dates separate from unconfirmed delivery dates.
Consider repairs, spare equipment, sharing with another department or purchasing only the minimum quantity first. Retain the basis and unknowns for safety or continuity concerns. Avoid wording that expands the request into replacing equipment that is not in scope.
A Japanese example to adapt
This is a fictional proposal to consider a purchase. Verify amounts, specifications and dates against your own documents.
