The documented problem

In April 2016 Toyota announced that parts shortages caused by the severe earthquakes on Japan’s island of Kyushu would suspend production on almost all of its vehicle assembly lines in Japan, in stages between April 18 and 23. Most lines restarted between April 25 and 28. After the Noto Peninsula earthquake on January 1, 2024, Toyota said many of its local suppliers and their affiliates had been affected, and that it would run its Japanese vehicle plants on parts in stock outside the affected areas.

Toyota’s 2026 Sustainability Data Book lists production halts from supply chain disruption caused by abnormal weather among its climate-related risks. It describes building a database from suppliers’ highly confidential information and training with suppliers regularly, so that supply chain information is visible before a disaster strikes. These are Toyota’s own accounts of its supply chain and its preparations. The OneShot workflow below keeps watch over each supplier site and carries a likely disruption through to the category manager’s decision.

The OneShot solution

Supplier site risk watch that ends in a recorded decision

Keep every active supplier site under current watch, so that a likely disruption reaches the category manager with the supplier’s own answer and checked backup options before parts run short.

  1. 01

    Map each site

    Load each active supplier and every production site from the supplier records, with the parts each site makes and any approved alternates. The OneShot agent resolves each site address to a precise location, confirms the supplier’s legal entity identifier and pulls its latest company filings. Mismatches between the records and the filings go to the category manager.

  2. 02

    Screen the company and its owners

    Check the supplier against sanctions lists for companies and each named owner against sanctions lists for individuals. Look up environmental compliance violations at the site, court cases naming the supplier and product recalls of what it makes. A name match is a lead to confirm, not a finding.

  3. 03

    Watch the ground at each site

    On the agreed schedule, check each site against disaster declarations, active wildfires, recent earthquakes and severe weather alerts. An event near a site opens a watch item with the event, its distance from the site and the parts at stake.

  4. 04

    Flag likely disruption

    The agent’s prediction tool scores each open item for the chance of a supply interruption, using the event, the site’s screening history, whether the parts are single-sourced and the stock cover on hand. Research on current reports fills in what the alerts leave out. Only items above the threshold the category manager sets become flags.

  5. 05

    Contact the supplier

    Email the supplier’s named contact for the site’s status, the expected effect on shipments and a recovery date, and call when the email goes unanswered by the agreed deadline. Record the answer, who gave it and when; a supplier that does not answer stays unconfirmed.

  6. 06

    Check backups and record the decision

    Find alternative suppliers for the parts at risk, profile them and screen each against sanctions lists. The agent’s optimization tool proposes how volume could shift across approved alternates within their stated capacity. Give the category manager the flag, the supplier’s answer and the options, then record the decision and the date to recheck.

What counts as complete

Every active supplier site has a current screen and hazard check, and every flag has the supplier’s answer or a recorded non-response, the backup options and the category manager’s decision.

Decisions and exceptions

  • A sanctions or name match goes to compliance for confirmation before anyone acts on it.
  • A new backup supplier enters the normal qualification process; the agent does not place orders or move volume.
  • A supplier that does not answer is not treated as either an outage or an all-clear.

What to measure

  • Sites with a current check
  • Time from event to flag
  • Supplier response time
  • Flags closed with a recorded decision

Establish the baseline and review period before launch. Compare completed cases, unresolved work and reviewer corrections against the same scope.

The agent’s tool basket

OneShot gives its agents the tools to analyze records, communicate, research and act on authorized business data. The platform carries the workflow from the first action through to the recorded result.

  • Supplier site and part records

    Read active suppliers, each production site address, the parts it supplies, stock cover and approved alternates; record the category manager’s decision and recheck date.
