Process Capability. Supplier shall produce a Process Capability Study which analyzes the information and data for the variable characteristics of all processes in a mutually agreed upon format. Supplier shall adjust processes as indicated by the Process Capability Study results to achieve targeted quality goals. Supplier shall develop X/R charts or comparable information to evaluate the capabilities of the processes. All critical dimensions or features of parts called out in Dot Hill's drawings shall meet a Cpk index of 1.33 (industry standard measurement).
Process Capability. For all process characteristics, Supplier shall perform process planning (work plans, test plans, operating supplies, tooling, machinery, etc.). For functional and process critical characteristics Supplier shall review the suitability of the manufacturing facilities and shall document the results. Documented test results and process data must be made available to Control4 electronically. Product quality is monitored with periodic audits. “Special characteristics,” identified and agreed on between Control4 and Supplier shall, if applicable, be monitored electronically by statistic process control. Special characteristics and process capabilities shall be determined and documented. If not agreed otherwise, the following values shall be maintained. Type Term Capability Machine capability MFU Cmk > 1,33 Short-term process capability PFU Ppk > 1, Long-term process capability PFU Cpk > 1,33 If the value above cannot be met, Supplier shall perform and document a 100% inspection prior to shipping, until the root cause has been determined and fixed. In the case of process disruptions and quality deviations, Supplier shall analyze the causes, shall initiate improvement measures and review their effectiveness.

Process Capability. (i) Supplier shall use statistical methods (e.g. SPC) to control the critical process parameters for its Process Capability: Cpk > 1.33
Process Capability. 9.1. For all process characteristics, Supplier shall perform process planning (work plans, test plans, operating supplies, tooling, machinery, etc.).
Process Capability. Infortrend shall produce a Process Capability Study which analyzes the information and data for the variable characteristics of all processes in a mutually agreed upon format. Infortrend shall adjust processes as Infortrend determines necessary based on the Process Capability Study results to achieve targeted quality goals. Infortrend shall develop X/R charts or comparable information to evaluate the capabilities of the processes. All critical dimensions or features of parts called out in Dot Hill's drawings shall meet a Cpk index of 1.33 (industry standard measurement).
Process Capability. Supplier will demonstrate, through reasonable documentation of validation, a process capability (CpK) of 1.33 or greater on any Purchaser-identified critical characteristics, dimensions or attributes, as applicable and set forth in the Exhibits to this Agreement.
Process Capability. The SUPPLIER has to verify its production processes with the use of capability studies (machine capability Cm, Cmk, preliminary process capability Pp, Ppk, long term process capability Cp, Cpk) and R&R-Studies on the adopted inspection systems (repeatability and reproducibility). If the SUPPLIER realizes deviations from the agreed specification, it has to optimize its process, while containing the deviation with 100%-checks on product before delivery.
Process Capability. Before the production release the supplier shall prove the capability of all processes and machines (Cpk (Ppk) ≥ 1.33 and Cmk ≥ 1.67 resp. individual part / component specific must be reached). If these requirements can not be met for certain processes, appropriate measures to ensure the quality of each part of the product have to be implemented (e.g. 100 % product testing).
Process Capability. The supplier is responsible that the manufacturing process is conducted under controlled conditions. With regards to the principal of error prevention the supplier has to conduct a risk analyze for the manufacturing process (e.g. PFMEA). He is managing the potential sources of defects. Mainly these potential sources are: Set Up Process. Management of tool defects. Management of disruption within the manufacturing process Quality check before delivery. Incoming goods check after outsourced processes (e.g. heat treatment). The supplier evaluates his process with regards to systematic influences and disturbances that could result in systematic variances. The supplier is responsible for implement measures to optimize the process. The procedure to manage that kind of variances is described in the VDA Book 4. (Alternative the AIAG guideline SPC) If the supplier is aware that the requirements are not fulfilled, he is responsible to find the right measures to ship only o.k. goods.
Process Capability. The SUPPLIER has to verify its production processes with the use of capability studies (machine capability Cm, Cmk, preliminary process capability Pp, Ppk, long term process capability Cp, Cpk) and R&R-Studies on the adopted inspection systems (repeatability and reproducibility). If the SUPPLIER realizes deviations from the agreed specification, it has to optimize its process, while containing the deviation with 100%-checks on product before delivery. Machine Capability Cm, Cmk The Cm index describes machine capability; it is the number of times the spread of the machine fits into the tolerance width. The higher the value of Cm, the better the machine. The Cmk index is used to study the position of the machine’s capability in relation to the tolerance limits, which describes the capability corrected for position. It is not much use having a high Cm index if the machine setting is way off center in relation to the middle of the tolerance range. A high Cmk index means, then, that it is a good machine with a small spread in relation to the tolerance width, and also that it is well centered within that width. Cmk Index shall usually be ≥ 2,00 and shall be calculated considering a control chart with typically 50 consecutively produced parts per cavity. Different Cmk target or data collection process can be required by RÖCHLING based on OEM specification. Preliminary Process Capability (Process Performance) Pp, Ppk Process Performance Index basically tries to verify if the sample generated from the process is capable to meet Customer CTQs (requirements). It differs from Process Capability (Cp, Cpk) in that Process Performance only applies to a specific batch of material. Samples from the batch may need to be quite large to be representative of the variation in the batch. An example of this is for a short pre-production run or a run@rate. Ppk Index shall usually be ≥ 1,67 and shall be calculated considering a control chart with 125 produced parts per cavity organized in subgroups of 5 parts each. Different Cmk target or data collection process can be required by RÖCHLING based on OEM specification. If the Index target is not met, products shall undergo a 100% inspection.
