Supplier Surveys

Also called: Supplier Questionnaires, Supplier Assessments
Supplier surveys are structured questionnaires sent to suppliers to gather self-reported information about their quality system, capabilities, certifications and processes, commonly used to support initial qualification decisions or periodic monitoring. Unlike a supplier evaluation, which is typically scored by the purchasing organization based on observed performance, a supplier survey collects information directly from the supplier, which the organization then reviews and verifies as needed.

What is Supplier Surveys?

A supplier survey is a questionnaire sent to a supplier asking them to provide information about their own quality system, manufacturing capabilities, certifications, and compliance status. It complements supplier evaluation by capturing information directly from the source rather than relying solely on the purchasing organization's own observed performance data.

Surveys are commonly used during initial supplier qualification, gathering foundational information such as certifications held, quality system scope, and key processes, before a purchasing organization decides whether to approve the supplier. They can also be used periodically to confirm that previously reported information, such as certification status, remains current.

Because survey responses are self-reported, organizations may verify certain claims, such as certifications, through independent confirmation or audits, particularly for suppliers providing critical components or services.

Why is Supplier Surveys important?

Supplier surveys give purchasing organizations a structured, consistent way to gather the same core information across all suppliers, making it easier to compare capabilities and identify gaps before a relationship begins.

Because surveys are typically completed by the supplier rather than observed by the purchasing organization, they are efficient to distribute at scale, particularly for lower-risk suppliers where a full on-site audit may not be warranted.

Periodic re-surveying helps ensure that previously reported supplier information, such as certifications or key personnel, has not changed in ways that affect the relationship, without requiring a full re-audit each time.

How does Supplier Surveys work?

A typical supplier survey process includes:

  1. Survey design. Define the questions relevant to qualifying or monitoring a supplier.
  2. Distribution. Send the survey to the supplier, often through a supplier web portal.
  3. Response collection. Gather the supplier's completed responses and any supporting documentation.
  4. Review. Assess responses against the organization's qualification or monitoring criteria.
  5. Verification. Confirm key claims, such as certifications, where warranted by risk.
  6. Follow-up. Request clarification or additional information as needed before finalizing a decision.

Supplier Survey vs. Supplier Evaluation

Comparison Supplier Survey Supplier Evaluation
Source of data Self-reported by the supplier Scored by the purchasing organization
Typical use Initial screening and periodic information updates Ongoing performance scoring and monitoring
Relationship Often an input into the broader evaluation May incorporate survey data alongside performance metrics

Real-world examples of Supplier Surveys

A medical device manufacturer sends a supplier survey to a prospective component supplier, asking about their ISO 13485 certification status, key manufacturing processes and quality system scope before proceeding to a formal audit.

An automotive supplier periodically re-surveys its approved suppliers to confirm certifications remain current and to capture any changes in ownership, location or key processes since the last review.

A contract manufacturer uses a supplier survey to quickly screen a large pool of potential vendors, reserving a full on-site evaluation only for those whose survey responses indicate strong potential fit.

Regulations and standards related to Supplier Surveys

ISO 9001 Clause 8.4 requires organizations to apply criteria for the evaluation and selection of external providers, and supplier surveys are a common practical method used to gather the information needed to apply those criteria, though the standard does not mandate surveys by name.

Organizations in more heavily regulated industries, such as medical devices and aerospace, often use supplier surveys as an initial screening step, reserving formal audits or more detailed qualification activities for suppliers providing higher-risk or safety-critical items.

Common mistakes with Supplier Surveys

Common mistakes include accepting self-reported survey information at face value without any independent verification, particularly for certifications critical to a supplier's approval status.

Other problems include never re-surveying approved suppliers, allowing outdated information such as expired certifications to go unnoticed, and using generic surveys that do not capture the specific criteria relevant to what a given supplier provides.

Frequently asked questions

A supplier survey collects self-reported information directly from the supplier, such as certifications and capabilities. A supplier evaluation is typically the purchasing organization's own scored assessment, which may use survey responses as one input alongside observed performance data.
It depends on risk. For critical suppliers or claims, such as certifications supporting regulated products, organizations often verify survey responses through independent confirmation or an audit rather than relying on self-reported information alone.
Supplier surveys are commonly used during initial supplier qualification and periodically afterward to confirm that previously reported information, such as certifications, remains current.
For lower-risk suppliers, a survey alone may be sufficient for qualification. For higher-risk or safety-critical suppliers, organizations typically use surveys as an initial screening step, followed by a more thorough audit before final approval.
There is no universal interval, but many organizations re-survey suppliers periodically, such as annually, or when a known change occurs, such as a certification renewal cycle or a change in ownership or location.
No. ISO 9001 requires organizations to apply criteria for supplier evaluation and selection, but it does not mandate surveys specifically. Surveys are a common, practical tool organizations use to gather the information needed to meet that requirement.
