Overview
In support of our manufacturing operations in both Newburn, Andover and the Czech Republic, we aim to work in collaboration with suppliers to achieve just-in-time delivery capability, high quality and lowest total cost of materials.

Supplier Selection and Approval
Suppliers are selected through analysis of their financial, commercial and technical capabilities. Suppliers will be required to provide documented evidence of their current quality and delivery performance measurements, manufacturing capabilities, plant lists, available capacity and annual financial reports. Supplier approval is accomplished by verifying the supplier's conformance to our specifications and reviewing the product and production processes through quality analysis. Quality and process audits may be conducted at the supplier’s facility. The supplier may also be asked to submit system and product data to verify process control.

Stannah Production Planning
A Sales and Operation Planning cycle (SOP) is used to forecast production requirements for the coming 12 months. This is communicated to key suppliers monthly, to allow medium to long term planning of capacity and material requirements.

Materials Supply
We work closely with key suppliers to provide visibility of our demand and the resulting just-in-time supply of materials. As materials are stocked at, or close to, their point of use within the manufacturing operation, our preference is for suppliers to deliver directly to the relevant production area(s). We aim to minimise the amount of non-value adding paperwork that is generated - we prefer periodic invoicing to one invoice per delivery. In return, suppliers can expect payment in full and on-time.

Component Quality Planning
A "Part Approval" process is used to control the introduction of new (or changed) components. This process is designed to ensure that only components with proven process capability are introduced into Stannah Manufacturing. Sample Approval documentation relating to production representative components must be signed off by Stannah before purchase order commitment will be raised. Further details can be obtained from the Quality Department.

PPAP
A 'Production Part Approval Process' (PPAP) is used to intoduce new or changed componenets to ensure that only parts with proven process capability are introduced into Stannah manufacturing. The process includes both Design and Process Failure Mode Effect Anaylsis (DFMEA and PFMEA) which involves Stannah suppliers. Each component must have PPAP approval from our Quality Department before being used for volume production. Further information can be obtained from the Quality Department.

Supplier Performance Measurement
Adherence to cost, quality and delivery standards is regularly reviewed with key suppliers. A vendor scorecard is used with major suppliers to provide a composite measure of performance across delivery and quality conformance, commercial management and involvement with Product Development.
Additionally, a reverse scorecard allows Suppliers to feedback on Stannah’s performance. Scorecard results are used as the focal point of periodic business reviews between Stannah and the respective supplier, and to initiate improvement activities where necessary.

Non-conforming materials
Suppliers will be informed promptly regarding non-conforming materials and will be required to supply either credit or free of charge replacements. Additionally, an issue form detailing the non-conformance will be raised. We expect suppliers to respond to these issue forms within 4 weeks of receipt. The response must detail containment actions, root cause analysis and longer term preventative actions to prevent recurrence. Such actions may be subject to audit by Stannah personnel and materials may be subject to re-qualification through the 'Part Approval' process.
