Nexa Bill of Information

The biggest gains to be achieved in next generation Product Lifecycle Management (PLM) implementations will be seen by companies that adopt a Bill of Information (BOI) approach which enables the real-time management and reporting from the entire compilation of information at any point along a product’s lifecycle – from concept through retirement.

Product companies use the term Bill of Materials (BOM) to describe the components that once assembled, represent a finished product. However, the BOM does not describe how the idea became a product which generated revenue.

With Nexa, Essig PLM uses the tern Bill of Information.  Like our DNA, the Nexa BOI serves as a comprehensive “blue print” for all of the information about the product, its relationships, and dependencies including the Bill of Materials (BOM) definition.

The Nexa BOI captures the entire data set required for design, testing, manufacture, delivery, sale, and support of a product throughout its lifecycle. Having all of this information available allows very tailored and specific pieces of information to be presented to various users, groups, departments and suppliers for example.

The Nexa BOI will enhance your competitive edge by:

  • Streamlining product data and processes
  • Reducing development cycle times
  • Improving the quality and reliability of the release to manufacturing and time to market

The Comprehensive Bill of Information

Companies that adopt a Bill of Information (BOI) approach with their Product Lifecycle Management (PLM) implementations will achieve the biggest gains. The BOI enables the real-time management and reporting from the entire collection of information at any point along a product’s lifecycle – from concept through retirement.

Essig PLM, Inc.’s white paper, The Comprehensive Bill of Information, provides insight into the fundamental concepts that make up a BOI, which serves as the “blueprint” that describes your finished product. To fully define your company’s intellectual property it is essential to capture, document and retain the BOI.

Nexa PLM Enterprise Integration exploits the full benefits of PLM, enabling the exchange of application-independent bills of material with your other critical enterprise applications such as MRP, ERP, and CRM systems. The fully integrated product environment that is facilitated by Nexa eliminates redundant pockets of information and re-keying errors between systems. Essig PLM has successfully delivered enterprise integration solutions to applications such as SAP®, Oracle® Manufacturing, SSA Baan™, J.D. Edwards OneWorld, and others, or can provide the tools or work with you to integrate Nexa with your own homegrown or legacy systems.
