Steps, by experience

Beginner (under 1 year)

  1. Ask purchasing or your manufacturer for the lead time of every major part.
  2. Mark the parts with the longest lead times and the ones with only one supplier.
  3. Put the longest lead times into the roadmap as fixed dates.
  4. Ask engineering whether a second, interchangeable part exists for the riskiest items.
  5. Check lead times again every month, because they change.

Intermediate (1 to 4 years)

  1. Score each part for lead time, single-source risk and end-of-life risk.
  2. Order long-lead parts early where the risk justifies the cost.
  3. Design in second sources for the highest-risk parts.

Experienced (5+ years)

  1. Set a supply-risk policy across products, including buffer stock.
  2. Agree with finance how much to spend to reduce schedule risk.
  3. Review end-of-life notices and plan redesigns before parts disappear.

Who can do this

Owner: Product manager

Can be delegated to

  • Delivery Manager: Track lead times and order dates
  • Hardware / manufacturing engineer or Tech Lead or Architect: Find second sources for risky parts

Reviewed by: Hardware / manufacturing engineer, Tech Lead

Tool examples

Jira
Add each long-lead part as a dependency on the roadmap.
Google Docs
Keep a risk score for each part in the BOM sheet.

Definition of done

  • Lead time known for every major part
  • Highest-risk parts have a plan
  • Monthly check booked

Common pitfalls

  • Checking lead times once and never again
  • Relying on one supplier for a critical part
  • Ordering too late to save money

If you lead the team

What good looks like: Long lead-time and single-source parts are known early and have a plan.

Ask your PM

  • Which parts have the longest lead times or a single supplier?
  • What's our backup if a supplier fails?

Warning signs

  • Lead times are discovered when ordering.
  • One supplier can stop production.

Do these first
