Supply Chain Management (This procedure covers management and review of our supply chain) SES-SCM-Rev01 No of Pages 3 Overview Management of Specialised Electrical Services Ltd.’s supply chain is crucial to ensuring that SES can deliver a high-quality service. The SCM document provides centralised control to ensure the supplier, manufacturer, wholesaler provide our company with the excellence we demand to ensure Specialised Electrical Services final product is of the highest possible quality for our clients. Supply Chain Engagement Initial selection and quality assurance of our supply chain will be undertaken through our Supplier Questionnaire (SQ) as per procedure SES-SS-Rev01 Subcontractor selection. • The criteria analysed from the Supplier Questionnaire is third party accreditation (ISO 9001, 14001, 45001, 27001). • We also look at records such as insurance details, quality, environmental and health & safety (HSEQ) performance / records as well as the size / financial security and sustainability of the company (Dun & Bradstreet), further checks are typically undertaken by taking up references and where deemed necessary face to face meetings and site visits at both the suppliers head office and their work sites. The minimum levels of performance are to be determined by the nature and risk and size of activity. • Approval of the supplier via the Supplier Questionnaire will be undertaken internally and where necessary technical or subject matter experts are involved to provide controlled governance and hold points (i.e. where further consideration of HSEQ and / or design matters are required). After approval the supplier is placed at “Approved Status” on the Approved Vendor List (Held on our internal systems). Remaining at “Approved Status” on the AVL requires annual update of insurances and third party accreditation certificates. • A 360 review will take place annually between the sub-contractor and Specialised Electrical Services to ensure of assurance and conformance. Document Reference SES-SCM-Rev01 Page 1 of 3 Supply Chain Review Ongoing monitoring and verification of a supplier’s quality is equally important as the initial selection, the processes and tools that Specialised Electrical Services use to ensure this is undertaken are as follows: • Supply Chain feedback system: This is a “in-house” system which is linked to other company data. The system requests and collates feedback from our supply chain and operational teams regarding performance against a number of predetermined measures. The feedback and associated comments from the reviews are automatically displayed on the supplier’s page for all staff to see. This ensures we can take into consideration previous performance of a supplier when considering the award of future work. • Feedback is also communicated to and discussed by the Supply Chain and Procurement Teams and the HSEQ Teams. Where necessary unfavourable feedback reports are investigated and closed out. The feedback can provide excellent topics for discussion at review meetings with the supply chain and help identify focus areas for continuous improvement. • Non-Conformances: these are recorded as per procedure SES-NC-Rev01 Non Conformance where the supplier has failed to comply with a requirement, specification, standard or procedure. Audit This procedure defines an auditable process to ensure that the audit procedure is being followed.
