Establishing a Data Analysis Procedure

[badidi]

hi everyone, i want to know the step to follow to establish a data analyse procedure

 

[Steve Prevette]

That is a very general question. I will point out that I have posted a viable data analysis procedure here based upon Statistical Process Control techniques. Please refer to Statistical Process Control Library (elsmar.com)

we produce a ball valve and we intend to get API 6D mongaramme. actually i work to etablish procedures for API Q1 and analyse of data is one of theme,

 

[Steve Prevette]

API Q1 is a copyrighted document that one must pay for, so I do not have a copy myself. I see it references ISO 9000 which certainly allows the use of statistical process control for data analysis and does have random sampling requirements. I did do some work for Schlumberger for their HSE department and they shifted to SPC and published a paper at a SPE conference some years back.

There is also this discussion on the COVE - How to correctly understand the bullet list d) of 6.3 Analysis of Data for API Spec Q1 (elsmar.com)

In that discussion I did also reference SPC and the Hanford Trending Primer that is here on the COVE. I am not saying it is the ONLY way to meet the requirements, but I am confident they would be acceptable to meet the requirement.

 

[Steve Prevette]

Repeating from the Conformity Matrix that I found for the past discussion:

"The organization shall establish processes to ensure that:a) importance of meeting customer, legal, and other applicable requirements is communicated at relevant functions within the organization; andb) results of analysis of data (see 6.3) are communicated at relevant levels and functions within the organization."

"The organization shall maintain a documented procedure for the identification, collection, and analysis of data to demonstrate the suitability and effectiveness of the quality management system. The analysis shall include data generated from monitoring and measurement, internal audits (see 6.2.2), management reviews (see 6.5), and other relevant sources. The data analysis output shall provide information relating to: a) customer satisfaction (see 6.2.1); b) conformity to product requirements; c) nonconformities and product failures identified after delivery or use, provided the product or documented evidence is available to facilitate the determination of the cause (see 5.10);d) characteristics and trends of processes and products including opportunities for preventive action (see 6.4.3); e) supplier performance (see 5.6); and f) quality objectives (see 4.1.3).The organization shall use data to evaluate where continual improvement of the effectiveness of the quality management system can be made."

Most of this is knowing what to measure that is specific to your product (you mentioned ball valves - I am fairly familiar with those from nuclear submarines). The verbiage above is relatively generic to ISO 9000, and NQA-1 and the "QA Rule" (10 CFR 830.122) which I had to work to in the nuclear industry.

thank you

Hi Badidi, good info above, but an easy way to start is by simply asking What, Why, When, Where, How, Who.

• Why do I need to do data analysis?
• What do I need to measure in order to get the data for the data analysis?
  • Why do I need this data?
• How will I measure and get that data?
• Who (or what) will measure and get/provide the data?
• When do I get this data? (How often)
• When do I communicate the data analysis?
• Who do I communicate the data analysis to?

etc. etc. etc.
