Procurement 101: Supplier Evaluation – How it works and why it’s important

What is Supplier Evaluation?

Supplier evaluation is the systematic assessment of a supplier’s performance and capabilities. It is a crucial process for businesses to ensure they are working with partners who can meet their needs and expectations. Evaluating suppliers thoroughly allows companies to identify the best partners, while weeding out poor performers. This leads to reduced costs, improved quality, and better customer satisfaction.  

The importance of supplier evaluation cannot be understated. It provides the evidence needed to make sound sourcing decisions. Companies rely heavily on suppliers for raw materials, components, logistics, and other services vital to their operations. Choosing the wrong partners can result in compromised quality, missed deliveries, higher prices, and risks to the supply chain. Robust evaluation minimizes these hazards. It also uncovers opportunities for improving supplier relationships and leveraging their capabilities for competitive advantage. The time invested in assessment today saves money and headaches down the road.

When to Evaluate

The main times a supplier should be formally evaluated include:

• Initial Selection – When first selecting suppliers, request information and assess their capabilities against your requirements. Set evaluation criteria and review proposals from potential suppliers to determine the best fit.
• Routine Monitoring – Monitor supplier performance at regular intervals as part of ongoing supplier management. Gather performance data and conduct evaluations to identify improvement opportunities.
• Contract Renewal – Re-evaluate suppliers when contracts are up for renewal. Review their performance over the contract period and determine if they still meet requirements. Renegotiate terms or consider other suppliers.
• New Product/Service – When outsourcing a new product or service, existing suppliers should be re-evaluated along with any new supplier candidates. Ensure they can meet the new requirements.

What to Evaluate

When evaluating suppliers, there are several key factors to consider:

Pricing

• How do the supplier’s prices compare to competitors? Are volume discounts available?
• Is the pricing structure fair and reasonable? Are there hidden fees?
• Does the pricing align with the value delivered?

Quality

• Does the supplier consistently meet quality specifications?
• Do they have quality control procedures in place?
• Can they provide testing reports or quality certifications?
• What is their track record with quality and defects?

Delivery

• Can the supplier deliver on-time, with the right quantities and to the right locations?
• Do they have the capacity to meet demand fluctuations or surges?
• What is their policy on managing backorders or stock-outs?

Customer Service

• How responsive is the supplier to inquiries, issues, and requests?
• Do they provide training or support as needed?
• Will they customize products or services to meet your needs?

Financial Stability

• Does the supplier have solid financials and good credit standing?  
• Are they able to sustain and invest in the business relationship?
• What contingencies exist if they go out of business?

Capabilities

• Does the supplier have the technical expertise to understand your needs?
• Can they deliver ongoing innovation and process improvements?  
• Do they have resources dedicated to your business?
• Are they keeping pace with changes in the market or industry?

Evaluating these key factors will provide a comprehensive view of supplier performance and enable informed decisions when managing suppliers.

Methods of Evaluation

Organizations use a variety of methods to evaluate suppliers and their performance. Some key methods include:

Scorecards

Scorecards are a systematic way of assessing suppliers on a range of criteria using a numeric rating system. They allow companies to benchmark supplier performance over time. Key metrics on a supplier scorecard may include quality, delivery, cost, customer service, and management factors.

Site Visits

Visiting a supplier’s production facilities first-hand offers valuable insights into their operations, capabilities, processes, and culture. Site visits allow for direct observation, interviews with staff, and review of practices. They can help verify if suppliers meet required standards and specifications.

Surveys

Surveys with quantitative and qualitative measures can provide feedback from various stakeholders on how they perceive suppliers. Customer surveys can assess their satisfaction with supplier performance. Internal user surveys can judge the supplier relationship experience. Supplier surveys allow self-assessment.

Product Testing

Obtaining samples of a supplier’s products or services and directly testing or inspecting them reveals if they meet requirements. This can include functionality, quality assurance, safety compliance, sensory evaluation, and more. Destructive testing puts products under stress to test limits.  

Questionnaires

Supplier questionnaires cover a wide span of topics to collect standardized data on capabilities, processes, certifications, costs, management, and risks. They provide snapshots of suppliers for comparison and analysis. Questionnaires work well for assessing potential new suppliers.

Key Performance Indicators

When evaluating suppliers, there are 5 key performance indicators to consider:

Quality

• Product quality – Does the product meet specifications and quality requirements? Is the quality consistent?
• Process quality – Does the supplier have quality control procedures in place? What is their defect rate?
• Quality certifications – Do they hold any ISO or industry-specific quality certifications?

Delivery

• On-time delivery – How often do they deliver orders on time, in full?
• Flexibility – Can they handle rush orders or fluctuations in demand?
• Lead times – How long are their average lead times from order to delivery?

Cost

• Pricing – How do their prices compare to market rates? Do they offer discounts?
• Total cost – Consider not just unit price, but total cost of acquisition.
• Open book pricing – Will they share cost breakdowns if requested?

Responsiveness

• Communication – How quickly and thoroughly do they respond to inquiries and issues?
• Customer service – How knowledgeable and helpful is their customer service team?
• Agility – How quickly can they respond to changing needs or priorities?

Compliance

• Regulatory – Do they comply with all relevant regulations and standards?
• Contracts – Do they adhere to contact terms and conditions?
• Ethical practices – Do they reflect your organization’s values?
• Reporting – Do they provide all required compliance documentation?

Weighing Criteria

When evaluating suppliers, it’s important to prioritize criteria based on your company’s specific needs and goals. A weighted scoring system can help quantify criteria and make comparisons between suppliers more objective.

• Identify the 5-10 most important criteria to evaluate (quality, cost, lead times, service, etc.). Rank or weight them based on priority.
• Develop a scoring system for each criterion. For example, use a scale of 1-5 or 1-10. Make sure the scale has clear definitions.
• Multiply the score by the weight to get the weighted score.
• Add up weighted scores to get the total for each supplier. Higher scores indicate better fit and performance.
• Focus comparisons on suppliers with top scores. Go with the one aligned closest to your weighted criteria.
• Re-evaluate criteria weights periodically to realign with evolving needs. Adjust scoring as needed.

By weighting and quantifying supplier criteria, you gain data-driven insights into which suppliers best fit your business priorities. A systematic process also provides objectivity. Just be sure to focus on key factors so the system doesn’t get too complex.

Conducting Assessments

Carefully managing the evaluation process helps ensure fair, objective, and constructive supplier reviews. Here are some best practices:

• Form a review team – Assign a cross-functional team representing key departments to evaluate each supplier. This provides balanced input.
• Gather data – The team should use performance reports, scorecards, surveys, and other sources to collect feedback on the supplier’s criteria.
• Normalize scores – Weighting criteria and standardizing scoring normalizes results across suppliers. This minimizes individual reviewer bias.
• Provide feedback – Review results with each supplier in a discussion. Highlight strengths, improvement areas, and performance goals.
• Track actions – Follow up on issues, measure progress over time, and document supplier responses. This closes the loop.
• Focus on facts – Reviews should be data-driven, not based on opinions or hearsay. Quantify and document assessment factors.
• Emphasize two-way communication – Encourage supplier participation to understand their challenges and perspectives. Make it a continuous improvement process.

Conducting methodical, fair, and collaborative assessments ensures an objective supplier evaluation program that builds partnerships.

Managing Performance

Once evaluations are complete, it’s important to have a plan for addressing any issues or opportunities identified. Here are some best practices:

• Corrective Actions – If a supplier scores poorly in certain areas, corrective actions should be put in place. This may involve requiring the supplier to undergo additional training, improve quality control processes, increase staffing, or make other changes to resolve the deficiencies uncovered in the evaluation. Agree on an improvement plan with clear timelines.
• Improvement Plans – Even well-performing suppliers can benefit from improvement plans to encourage continuous enhancement. Collaboratively develop a plan to boost capabilities in areas like responsiveness, reporting, sustainability practices, or other metrics. Offer support and resources to aid the supplier in leveling up.
• Incentives – Offering incentives to top-performing suppliers can further motivate them to go above and beyond. Consider providing bonuses, increased business, preferential commercial terms, public recognition, or access to new opportunities as rewards for exceeding expectations.
• Recognition – Positive reinforcement goes a long way. Be sure to recognize and reward excellent suppliers. Feature top partners in company publications, invite them to events, ask them to speak at conferences, or find other ways to recognize suppliers who demonstrate exemplary performance.

Proactively managing supplier performance helps strengthen the relationships and results. Ongoing monitoring and dialogue ensures both parties are aligned on priorities and working collaboratively towards shared objectives.
