A '''process development execution system (PDES)''' is a system used by companies to perform development activities for high-tech manufacturing processes.

Software systems of this kind leverage diverse concepts from other software categories like [[product lifecycle management|PLM]], [[manufacturing execution systems|manufacturing execution system (MES)]], [[Enterprise content management|ECM]] but focus on tools to speed up the technology development rather than the production.

A PDES is similar to a [[manufacturing execution systems]] (MES) in several ways. The key distinguishing factor of a PDES is that it is tailored for steering the development of a manufacturing process, while MES is tailored for executing the volume production using the developed process. Therefore, the toolset and focus of a PDES is on lower volume but higher flexibility and experimentation freedom. The tools of an MES are more focused on less variance, higher volumes, tighter control and logistics. Both types of [[application software]] increase traceability, productivity, and [[Quality (business)|quality]] of the delivered result. For PDESs quality refers to the capability of the process to perform without failure under a wide range of conditions, i.e. the robustness of the developed manufacturing process. For MESs quality refers to the quality of the manufactured good/commodity. Additionally both software types share functions including equipment tracking, product genealogy, labour and item tracking, costing, [[electronic signature]] capture, [[Product defect|defect]] and resolution monitoring, [[executive dashboard]]s, and other various reporting solutions.

In contrast to [[Product Lifecycle Management|PLM]] systems, PDES typically address the collaboration and innovation challenges with a bottom-up approach. They start-out with the details of manufacturing technologies (like [[Product_lifecycle_managementProduct lifecycle management#Product_and_process_lifecycle_management_Product and process lifecycle management .28PPLM.29|PPLM]]), a single manufacturing step with all its physical aware parameterization and integrating steps into sequences, into devices, into systems, etc.

Other rather similar software categories are [[Laboratorylaboratory information management system|laboratory information management systems]]s (LIMS) and [[laboratory information system]] (LIS). PDESs offer a wider set of functionalities e.g. virtual manufacturing techniques, while they are typically not integrated with the equipment in the laboratory.

PDESs have many parts and can be deployed on various scales – from simple [[Work in Progress]] tracking, to a complex solution integrated throughout an enterprise development infrastructure. The latter connects with other enterprise systems like [[Enterprise resource planning|enterprise resource and planning system]]s (ERPs), manufacturing execution systems (MESs), [[product lifecycle management]] (PLM), [[SCADA|supervisory, control and data acquisition]] (SCADA) solutions and [[Automated planning and scheduling|scheduling and planning system]]s (both long-term and short-term tactical).

# check process flows using these rules. This rule check verifies the principle manufacturability of a newly designed manufacturing flow.

The processing rule check gives no indication about the functionality or even the structure of the produced good or device. In the area of [[semiconductor device fabrication]], the techniques of [[semiconductor process simulation]] / [[Technology CAD|TCAD]] can provide an idea about the produced structures. To support this ’virtual fabrication’, a PDES is able to manage simulation models for process steps. Usually the simulation results are seen as standalone data. To rectify this situation PDESs are able to manage the resulting files in combination with the process flow. This enables the engineer to easily compare the expected results with the simulated outcome. The knowledge gained from the comparison can again be used to improve the simulation model.

After virtual verification the device is produced in an experimental fabrication environment. A PDES allows a transfer of the process flow to the fabrication environment (for example in semiconductor: [[Fab (semiconductors)|FAB]]). This can be done by simply printing out a runcard for the operator or by interfacing to the [[Manufacturing Execution Systems]] (MES) of the facility. On the other hand a PDES is able to manage and document last minute changes to the flow like parameter adjustments during the fabrication.

Line 43:

Development activities within high tech industries are an increasingly collaborative effort. This leads to the need to exchange information between the partners or to transfer process intellectual property from a vendor to a customer. PDESs' support this transfer while being selective to protect the IPR of the company.
