Queue time, review time and four fixes: cutting supplier qualification cycle time without skipping checks

Qualifying 200 new suppliers a year at six to eight weeks each is a problem practitioners regularly discuss on Reddit. We listen to these discussions to share what is being talked about and to add to the conversation. This piece gives UK quality and procurement teams a way to find where those weeks go and four fixes to remove them, none of which skips a check.

Supplier qualification cycle time is the number of calendar days between a complete supplier request and the approval decision. It has two parts: queue time and review time.

Where the weeks go in supplier qualification cycle time

Most of the elapsed time in a long qualification is not spent assessing anything. One practitioner view in the discussions behind this piece is that most of the six to eight weeks is queue time between teams. The records can confirm or refute that for any company.

Queue time: the wait between teams

Queue time is the time a qualification waits for someone to start work on it. A pack sits in the quality manager's inbox during a customer audit. Legal picks it up only after procurement has finished. A reminder goes unanswered for a week. Time spent waiting for the supplier to return information is a separate wait with a different owner, so track it as its own bucket.

Review time: the work that needs a judgement

Review time is the time someone spends actively assessing the supplier. It covers reading a questionnaire, checking a certificate and deciding whether the supplier can meet the specification. These tasks usually take hours, not weeks. They are also the part that protects the business, so the aim is to keep review time and shrink everything around it.

Finding the split in your own records

Record four timestamps for each team involved: the date the pack was received, assigned, started and completed. Queue time is started minus assigned. Review time is completed minus started. Flow efficiency is review time divided by total cycle time.

The illustrative figures below show why the split matters. Two hundred suppliers at six to eight weeks each is 1,200 to 1,600 supplier-weeks of elapsed time a year. If review accounts for one week of a seven-week average, flow efficiency is about 14 per cent and six of the seven weeks are queue. Without a tracking system, pull 20 recent suppliers from email and the tracker and rebuild the dates by hand.

Four fixes ranked by the weeks they remove

The order below follows impact in the scenario above, where queue time is the largest share. Parallel review attacks queue time directly. The other three reduce the amount of work that enters the queue. Confirm the order against your own timestamps before committing effort.

Where the weeks go The fix What it saves
Reviews pass from quality to procurement to legal one after another Open every review on the same day with one deadline and one person chasing Several sequential waits collapse into one
Suppliers resubmit evidence that an accredited body has already assessed Accept a valid, in-scope certificate in place of a repeat questionnaire section Whole review steps drop out for certified suppliers
Low-risk suppliers join the same queue as everyone else Apply a written fast track rule with fixed conditions Low-risk suppliers clear in days, not weeks
Reviewers debate terms that do not change the approval decision Put audit rights, change notification and insurance renewal into the contract Reviews cover only what decides approve or reject

Removing queue time between teams with parallel review windows

A sequential process adds every team's wait together. If quality, procurement, finance and legal each take five working days to pick up and finish a pack, the supplier waits up to 20 working days. Opening all four reviews on the same day with one shared deadline brings that to five.

A parallel review window needs two things. Every reviewer receives the full pack on the same day and knows the closing date. One named person, usually a supplier quality coordinator or a buyer, owns the chasing. That person sends one reminder at the midpoint and escalates on the deadline, so reviewers receive a single prompt and not four.

A shared record makes this easier, because nobody has to ask where a pack is. Ideagen's page on managing supplier qualification and performance in one workflow shows how one workflow cuts the chasing between teams.

Accepting valid existing certificates: what to check

A supplier holding a current ISO 9001 certificate has already been audited by an independent body. Asking the same questions again adds time and little evidence. Accept the certificate in place of the matching questionnaire section only when it passes these checks:

  • The certification body is accredited, by UKAS in the UK or by an accreditation body that is a signatory to the IAF multilateral recognition arrangement
  • The scope covers the product or service being bought
  • The site address matches the site that will supply you
  • The standard and version are the ones you require, such as ISO 9001:2015
  • The expiry date is in the future and the certificate has not been suspended or withdrawn
  • The certification body's own directory confirms the certificate is live

A certificate that fails any check goes back into the normal review. The shortcut applies only to the sections the certificate genuinely covers.

A fast track rule and a contract clause: two ways to take items out of the queue

A fast track rule is a written set of conditions under which a supplier skips the full review and receives a minimum check set. Typical conditions are spend below a stated threshold, no access to company systems or personal data and no effect on product or service quality. How a company defines low risk sits outside this piece. The rule works only if procurement can apply it without circulating the pack, and if a sample of fast-tracked suppliers is rechecked each year.

Some items never change the approve or reject decision. Right to audit, notification of changes to process or sub-suppliers, insurance renewal, record retention and corrective action response times belong in the contract, not in the review. Where a supplier will process personal data, UK GDPR requires a written contract with processor terms, so those terms are contract items by default. Anything that decides whether the supplier can meet the specification stays in the review.

What to look for in third-party supplier qualification management for UK companies

Third-party supplier qualification management is the process of assessing and approving a supplier before the first order. For cycle time, the system should timestamp every handoff so queue time and review time can be reported by team and by supplier. It should assign reviews in parallel with a shared due date and send automatic reminders from one source.

It should also hold certificates with scope, site and expiry dates, and alert before they lapse. Rule-based routing should send suppliers that meet the fast track conditions down the short path. A contract terms checklist keeps non-decision items out of the review. Reports should show where cases wait, not just how many were approved.

Measure the wait, protect the checks

Supplier qualification cycle time falls when queue time falls, and queue time falls when reviews run together, evidence already held by an accredited body is accepted, low-risk suppliers follow a short path and contract terms leave the review. Every review that decides approval stays in place. The first step is to timestamp the next 20 suppliers and see how much of the cycle is waiting.
