In its search for process optimization, Novy contacted Ordina for a thorough audit. We analyze the information flows for production monitoring within the company by means of an S95 audit. The purpose of the audit is threefold: to produce an overall picture; to identify the risks, difficulties and areas for improvement; and develop proposals for solutions, ranging from quick wins to larger projects. An S95 audit uses the terminology and models from the international ANSI ISA-95 standard. For example, these demarcate the boundaries between ERP, MES and WMS functionality. S95 helps in the design and synchronization of these systems and makes the information on stocks and orders more up-to-date and reliable.
