4.2 Statistical Process Control(SPC): Using the statistical technology（control chart）for analyzing the stability of the process or output data，proper measure to reach and keep the statistical control status to improve the process ability.
统计过程控制：使用统计技术（如控制图）去分析一个过程或输出数据的稳定性，采取适当的措施去达到和保持统计控制状态并改进过程能力。建筑管理
4.3 Control of chart：The classical and effective tools to be ud for reaching SPC control.
控制图：达到统计控制的典型和有效工具。
4.4 Ability of control: The ability of process under the SPC can be confirmed, the data must be random, independent, and normally distributed.
控制能力：只有过程在统计控制状态下才能被用于SPC控制，数据必须是随机，独立的和符合正态分布的。
5.0 PROCEDURE（程序）

5.1 Parametric choice：Quality engineer, Design engineer or manufacture engineer together to confirm the way of collect data, information of each batch, frequency and which control of chart we need.
参数选择：质量工程师，客户工程师和制造工程师确定数据收集方法，分组信息，频率和所要使用的控制图。
SPC control need follow the customer 2Ddrawing key dimension or process key point information to t up. (Follow CP, BOO, 2D drawing info to make SPC control standard).
SPC控制需要按照客户图纸重要尺寸的管控或生产过程中重点需要管控的内容对过程进行控制。
5.2 SPC chart choice: For the continuous data and normal distribution, usually u the X bar-R, X bar-
S, I-MR. For the attribute data, usually u the failure rate P-chart.
SPC图形选择：对于计量型数据并且满足正态分布，通常采用的是：均值变差图(X bar-R)，均值标准差图(X bar-S）和单值极差图I-MR。对于计数型数据，通常采用不合格品率的P图。

5.3 Confirm the control limit and alarm rule:
SPC system will bring about the control limit according to the historic data; it will make alarm for the data out of control limit and tolerance of customer requirement. When make a issue alarm, we need to take a action for improving as soon as possible.
确定控制线及报警规则：
SPC系统将根据原始数据建立控制线，而且超出控制线及客户公差线将报警。当发生问题警报，我们需要尽可能快的采取行动改善。

5.4 Execution performer: Production operator and IPQC need to collect the data and record it into SPC system. Recorder need to follow the CP, BOO and customer drawing requirement.
生产操作员和IPQC按规定收集并记录数据。记录需要依据控制计划，BOO和客户图纸要求进行。
5.5 Action plan：Operator and recorder---leader---technician---engineer（ME, QE, DE）--manager
beware
IPQC and operator need to judge the process stability at any time, when found the control chart issue to notice DE, ME and QE
IPQC和生产人员应随时判断工序是否处于稳定受控状态，当控制图上的点发生异常时应及时通知工艺工程师，制造工程师和质量工程师。英语能力描述
IQP: STA-400 Issued: Oct/28/2010 Page: 4 of 5
When the control chart have issue, DE, ME and QE must analyze the issue with QE, and make actions improve and avoid this issue.
当控制图上点排列发生异常时，工艺工程师，制造工程师和质量工程师应及时对此问题组织分析，必要时采取纠正和预防措施。
