Analyse-it：质量控制与改进版

 

Improve your products and services with statistical process control (SPC).

 

 

Ideal for anyone involved in manufacturing products, managing processes, implementing a six sigma or other quality improvement programme.

 

Meet your customers’ expectations and keep them satisfied with powerful statistical analysis to understand processes, bring them under control, and find improvements that better your product.

 

Bring processes under statistical control

Gain insight and improve process performance with Shewhart variable and attribute, CUSUM, and moving average control charts (EWMA & UWMA). Apply WECO, Nelson and Montgomery rules to help identify possible out of control situations. Use stratification to gain further insight into problems and spot trends and patterns. And when you've implemented improvements, or made other changes, phases let you track performance before and after so you can ensure improvements have been made and are sustained.

 

Ensure products are meeting end-user specifications

Determine process capability indices for process performance to ensure you deliver products that meet your customers’ requirements. A happy customer means fewer rejected goods and service complaints, improving your business and lowering costs.

 

 

Identify improvements that will reap the most rewards

Pareto analysis helps you quickly identify commonly occurring defects so you can focus your efforts making improvements that will reap the most rewards. Stratification lets you break-down defects so you can identify contributing factors, such as an operator that is influencing defect rates, or look at defects before and after process improvements to ensure the changes are reducing defects.

 

 

All the features from the Analyse-it Standard Edition are also included, so you can improve processes and products by identifying solutions using hypothesis tests and model fitting techniques.
