The 7 Quality Tools | In-Process and Final QA/QC

The term quality means different things to different people. Quality as conformance to specification. The 7 Quality Tools.

(I) Customer-based quality: - Fitness for use meeting customer expectations.

(ii) Manufacturing quality: - Conforming to design specifications or requirements having no defects.

(iii) Product quality: - The product has something those other Similar products do not that adds value.

(iv) Value-Based quality: - The products are the best combination of price and feature.

7 Quality Tools 

The 7 QC tools are simple statistical tools used for problem-solving. 

(i) Qc tools

(ii) Continuous improvement

(iii) Manufacturing process

(iv) Quality Control

(v) Root cause analysis

(vi) PDCA (Plan do check act.)

(vii) Efficiency

Methodology for solving quality problems following seven QC tools are required.

What is quality? | 7quality tools | In-Process and Final QA/QC


Use Quality sort names or terms

FIFO = first in first out

JIT = Just in time

PCRO = Public community regulatory organization

LQC = Line quality control

CAPA = Corrective and privative analysis

QIR = Quality incident report

TPM = Total productive maintenance

BSR = Bonded storeroom

TS = Total Solids

TSS = Total suspends solid

TDS = Total dissolved solids

TVS = Total volatile solid

TFS = Total fixed solids

INCOMING QA / QC

PROCESS DESCRIPTION of incoming QC:

After receipt of intimation about the receipt of raw materials and packing materials from stores through Material Receipt cum Inspection Report (MRIR), the samples are drawn as under:

a). A composite sample adequate for testing from each lot of raw materials i.e. one sample from different batch no’s & a composite sample from 25% containers from each lot.             

b). 5 pcs. of packing materials from each variety & each lot.

Inspection of the materials is carried out as per documented standards for raw materials & Packing materials & method of tests of raw materials. The records of raw materials & packing materials testing are kept in the Raw Materials Test Report and Packing Material Inspection Report respectively. In case GCS is written on the MRIR sample is not tested but only preserved for at least three months and first supplies from such suppliers are tested as per plan in each quarter.

In the case of new raw materials, tests are carried out and their acceptance /rejections are marked on the Supplier Selection Form Raw material rejection report is attached for rejected materials.

Conformity or non-conformity of material is recorded in the MRIR. In the case of accepted material, the MRIR is sent directly to stores. In case of non-conforming material, the MRIR is sent to V.P. / Head (O) who shall evaluate the material and may authorize acceptance of material under deviation in case it does not affect the quality of a final product.

Laboratory reagents are prepared as per documented instruction and are kept well-identified and their shelf life is maintained as per documented instruction.

PROCESS OUTPUTS: 

a) Decision to accept/reject incoming materials to stores.

b) Supplier selection forms to the purchasing department with remarks.

IN-PROCESS AND FINAL QA / QC

PROCESS DESCRIPTION:

In-Process Inspection & Testing

After receipt of intimation from production, the samples of intermediate & finished goods are drawn and tested as per documented standards and instructions for methods of test. In the case of lacquers, dyes & pigment solutions & acrylic binders the Application Test is carried out and records of chemical & application inspections are kept in the respective batch sheets & F.G. Application Test Report respectively, and results are conveyed to the production process.  

Samples of all the batches of finished goods are preserved duly identified for at least 8 months for domestic and one year for export for reference. Old counter samples are renewed within one month and disposed of through re-cycling in production. Samples of the finished batch of each product as control samples are preserved for test comparisons. These samples are replaced with fresh lots after every six months. 

If in 5 months no fresh batch is made, a lab batch is taken & after its approval for all Q.C. tests, the same is kept as the control sample. For Matt Lacquer & Filler, the control sample is replaced after 3 months. For discontinued products, samples may not be kept. The records are maintained in the Control Register (F-Q070-03). If the product is discontinued then the counter sample is disposed of as hazardous waste to TSDF or used in a similar natural product after getting approved from HOD (R & D).

PROCESS OUTPUTS: a) In-process test results to production.

                 b) Decision to pass/fail finished materials to production.
