DRESS MAKING - CITS

• Inspection audits: This system involve a systematic review of the production process, from the selection
of raw materials to the final output. This helps identify any potential flaws or deviations from the agreed-
upon quality standards. By closely monitoring production, fashion companies can address and rectify
issues timely, ensuring a more consistent and reliable product.
• Lab testing: It is another popular method employed within the fashion industry to evaluate the quality
and performance of various materials and finished products. This technique includes tests, such as
colorfastness, shrinkage, and fabric strength, to ensure the longevity and durability of the garment or
accessory. Although lab testing provides valuable information on the performance of a product, it may not
cover all aspects or foresee real-life scenarios of wear and tear.

• Sampling: It involves randomly selecting a certain percentage of garments from a batch or production run
and thoroughly inspecting them for quality. This helps identify any defects or inconsistencies in the finished
garments and determine the batch’s overall quality level.
By implementing the above quality assurance systems, clothing manufacturers can take preventive action
against defects, elevate product quality, reduce costs, comply with industry standards, enhance brand
image, and promote sustainable and ethical practices.
9 Statistical Quality Control (Sqc)
Statistical quality control refers to the use of statistical methods in the monitoring and maintaining of the quality
of products and services.
9.1. Basic Categories of Statistical Quality Control (S.Q.C):
All the tools of SQC are helpful in evaluating the quality of services. SQC uses different tools to analyze quality
problem. SQC comprises the set of statistical tools used by quality control professionals. It can be divided into
three broad categories:
Descriptive Statistics

Statistical Process Control (SPC)
Acceptance Sampling
1 Descriptive Statistics:
Descriptive Statistics involves describing quality characteristics and relationships. This group includes the
mean, standard deviation, range and distribution of data.
2 Statistical Process Control (SPC):
The statistical process control (SPС) is applied in established technological processes in order to observe,
analyze, and regulate them. The use of SPC allows for timely warning in case of a deviation and, if
necessary, to correct the parameters of the process. The application of SPC is a prerequisite for the timely
detection of the reasons behind quality deterioration. It helps in decreasing the defects, maintaining the
quality at a selected level, and improving the technological process. The application of statistical techniques
to determine whether a process is functioning as desired. SPC is used to determine whether the process
is functioning properly or not.
3 Acceptance Sampling:
This involves random inspection of a sample of goods. The application of statistical techniques to determine
whether a population of items should be accepted or rejected based on inspection of a sample of those
items.
10 Total Quality Management:
A cost effective system for integrating the continuous quality improvements of people at all levels in an organization
to deliver product services, which ensure customer satisfaction.
The concept of bringing a quality focus to every aspect of an operation from raw materials received to accounting
invoice accuracy.
Companywide quality management system involving all employees in activities aimed at improvement of product
quality, production process and services.
