A layered structure:

The interactions between an applications program and its information system resources are typically hardcoded into application software. This is not appropriate, however, when applications software is used in a CIM environment with data stored centrally. Then some common utilities are needed to provide an interface between applications and resources, such as communications Networks, databases and presentation devices. These common utilities make up pne of a series of layers in a software configuration and lead to the overall design being termed a layered structure. The three levels are the applications at the higher level, the data mounted on computer stores at the lower level and common services utilities at the intermediate level. The repository is also at the intermediate level. The common services utilities can be structured to provide support to applications through a system enabler, an application enabler and the data repository.

The application enablers

Application enablers support families of applications with common application functions by managing application interactions. An application enabler is built on a system enabler. An application family is a group of closely related applications that provide similar business functions and have common requirements. A shop-floor application family may include process routing, alert monitoring and status display applications. These three applications may be run at the same plant Workstation; they may operate on the same personal computer, they may even be dependent on another application for their execution, e.g. job dispatch.

In house developed software:

Before 1980, most cell control and management software was written by the user using C programming language. In house development was necessary because satisfactory third party software options were not available. The cost of these programming projects was substantial because studies indicate that software development in C cost $30 to$40 per line of code. In addition, the complex and cryptic nature of code drove up the costs of modifications and updates to existing programs.

The in house developed programs were written to address the specific control needs of the cell, and the software interfaced with other in house developed software in other enterprise areas. In addition, the lack of available interface software or drivers for equipment in the cell was not a problem since all the code was generated as a part of program development. However, these advantages were offset by a major disadvantage in cost and the inability to change the software easily when the cell hardware or configuration changed.

Self Directed Work Teams:

The concept behind self directed work teams has been evolving for the last 50 years. The dramatic changes in the global market and the increase in the use of technology in manufacturing since the 1970s has accelerated the interest in team based management. Global market pressures require manufacturers to have rapid response to customer needs, frequent new product introductions, increased productivity at all levels in the organization, lower production cost, and higher quality. Achieving these order-winning criteria with the work force management policies of the 1950s and 1960s is not possible. As a result, manufacturers interested in achieving world-class status are ready to consider a change in management style and to embrace the concept of manufacturing teams.
