Configurable software, Good

This is where the hnal version the software is tested, through structural testing and functional/stress testing prior to releasing the LIMS instance for use in the production enviromnent. This environment will be strictly controlled and will only be used for validation and qualification activities. The environment, hardware, software, data and configuration should be an accurate representation of the production environment. Testing should be in accordance with good IT practices and formally documented. 

The key to the process is to understand the system that is being proposed. It is good practice for the auditor to spend time reviewing the User Requirement Specification and the system descriptions and understanding of what software categories exist for the proposed system. This should be followed up, with the postal audit checklist. This will also provide valuable information to enable the auditor to plan the audit. Available information should be used to customize the audit checklist to address the specific issues that are relevant to both the supplier and proposed project. Consider, for example, a system that includes hardware and software, where some of the software is custom, other parts are configurable and yet others are part of a standard package. The auditor will need to establish how each part of the system will be developed, and how the build phase will be controlled. There may even be more than one supplier. The auditor would need to split up the main elements and examine how each part of the system will be built. 

Once defined, the business process transactions can be configured within the development environment of the MRP II system. There are normally instances when it is easier to amend the business process to fit the standard functionahty of the MRP II product software than to make a customized bespoke modification. Any bespoke modiflcations, like the interfaces, must be fuhy documented in design specifications, test speciflcations, and test records. One important aspect to avoid during configuration is to set up the system to accept default user entries. There have been several recalls within the pharmaceutical industry because users failed to recognize that a default entry on their MRP II systems was incorrect. It is always a good idea to have positive user confirmation of key data entry or decision points. If defaults are stih required then make them... 

As consumers of ERP systems, manufacturers and their trading partners face the risk of being stranded when their systems do not interoperate. The lack of interoperability in manufacturing supply chains can create significant costs (Brunnermeier and Meutin 1999), tmd those costs tend to be hidden. More accurate cost structures must be developed for information goods, particulady for buy-configure-build software applications. Unlike off-the-shelf software applications, ERP systems are more like traditional assets, in the business sense, with capital costs and ongoing operational costs. 

Manufacturers should have basic good software development, testing, and configuration management processes in place. 

A good qualitative insight into the transitions involved in the color change of sensors can usually be obtained from density functional theory (DFT) and other theoretical methods that have proved to be a very accurate tool for theoretical studies in supramolecular chemistry.DFT appears to be a reasonably accurate theoretical method that is both widely available in various software packages and can be run on personal computers, that is, does not necessarily require Unix or Unix-like environments, servers, and so on. On the other hand, multireference configuration interaction methods typically offer accuracies of about 0.1 eV...
