There are about 700 application users with an average of 300 concurrent users, and four MESs systems that exchange data with the SAP R/3. Each manufacturing site installed a different MBS system based on the topology described in the Site MES Application example above. The ERP application passes GMP relevant data (including production orders, bills of materials, materials allocation in the warehouse, materials consumption data, and materials status) back and forth with the MES systems. 

QTS software validation specifications lack details such as the hardware platforms the software should run on (model number, CPU [central processing unit], RAM [random access memory], hard drive size, free hard drive space, etc.), the software operating system, software database specifications (such as number of records accommodated, number of fields, whether those fields are character or numeric or date or alphabetical fields), the number of concurrent users allowed, the development platform used to write the application, network information, report contents and other information needed to perform testing properly. 

Knowing what software is used within a company is one thing. Knowing what the software license encompasses is a different story. It is not uncommon for an organisation who uses software to be unaware of issues such as the number of users allowed (named users or concurrent users), the license expiration date, product warranties, (period of) software support, consultancy (tariffs), delivery of upgrades (like Y2k-compliant versions) and so on. A contract management system should track the software (and likewise hardware) contracts. 

Systems can often be designed and scaled to meet the requirements of individual organisations. To mitigate the risk of poor system performance healthcare organisations should take appropriate measmes at design time to estimate the numbers of concurrent users. Hosting organisations can use this information to predict the specification and architecture of systan components required to meet performance requirements. 

In many implementations healthcare organisations choose to roll out a system in stages gradually increasing the numbers of concurrent users as different locations...

With licenses organized bythe concurrent user model, only active user accounts are counted, which are concurrently working with the CDS. By this model, the same licenses could first be used by a site in, for example, Japan and later on in the United States due to the time shift. 

A product development system requires a system executive that controls the execution of application programs a database management system, user interfaces, support utilities, networking capabilities and distributed computing. The executive system must support multiple and concurrent users, who may operate either in batch mode or interactively. 

The database system should not impose constraints on a preferred sequence of activities in the design process. Concurrent users must have access to the system simultaneously independently of their activities. This is one of the foundations of simultaneous engineering [8].
