13. Supply Chain Management

The key role for our procurement activities is to create a sustained competitive edge for Instalcom by managing the acquisition of all externally supplied resources upon which the business depends both now and in the future. The Senior Leadership Team believes that applying best – practice methods to the process of selecting and managing our suppliers is a major contributor to our long – term business success. This will be seen in better solutions for our clients, faster deployment of innovation, low total costs, lower risk and enhanced contribution to our goals. The procurement team are responsible for ensuring best value is achieved for Instalcom, this applies to goods and services associated with operational or overhead spend. To ensure we consistently achieve best value: we operate an approved supplier list, agree T&C’s and pricing, work with internal stakeholders to review and monitor supplier performance, carry out audits on suppliers, continually review potential new products and sources of supply. We work across many different departments and recognise that each have their own exacting needs and demands from the supply chain, we provide specialist support, advice and expertise to project managers.

Our supply chain management team are MCIPS qualified and utilise accepted best practice to drive innovation and achieve a differentiation from our supply base. As part of a £150m+ organisation we also aggregate our spend portfolio group-wide in order to leverage the market more effectively, this ensures we are maximising our utilisation of optimum suppliers and delivering best value throughout the project cycle. All projects are allocated a procurement lead prior to design commencement (or pre-commencement where the client has already undertaken the design) this individual’s responsibility is to develop the project procurement strategy and ensure we achieve the best commercial and technological results for the project. Key projects are allocated procurement resource who will be site based as appropriate to ensure a consistent approach Instalcom’s procurement procedures are cascaded from group level and utilise best practice from across industry to ensure we achieve differentiation from our supply chain, as well as effectively protecting the interests of ourselves and our clients. The procurement team are actively involved with the construction planning process to ensure timely deliveries of key materials (especially those sitting on the critical path). At the initial programme development stage the procurement lead is responsible for the issuing of manufacturers lead-in times to the project planner, these are then incorporated into the baseline construction programme. At all stages through the project this document is utilised as the key tool to ensure the procurement and expediting of materials is undertaken as timely and efficiently as possible. These key dates will also include any commissioning/erection periods as required.
