Quality of product and service along with the efficiency of the work force is the foremost objective to produce products and service of the high standard, which meets all the specifications, including environmental concern and safety.<br />Commitments to valued customer:<br />
    • Maintaining the highest achievable quality possible
    • 54. The most competitive pricing in the world market
    • 55. Shortest lead-time with on time delivery
    • 56. The best environment for ethical standard in accordance with world compliance standards
    Objective<br />Objective<br />Objectives of these policies are:<br />
    • To understand customer’s perspective of quality
    • 57. To provide better quality of products and service
    • 58. To provide good and safe working environment to the workers, which includes human value, respect, justice, cleanliness, discipline and equality between workers and others
    • 59. To implement quality control system with the aim to achieve zero defect level through efficient management, research, development and continuous improvement
    Cost and Quality<br />Cost and Quality<br />Cost and Quality<br />QUALITY: Quality is defined as “Totality of characteristics of an entity (product, service etc.) that bears on its ability to satisfy stated and implied needs.”<br />QUALITY CONTROL: Is an effective system for interchanging the quality maintenance and quality improvement efforts of various groups in an organization so as to enable production at the most economical levels which allow full satisfaction for the consumers.<br />TOTAL QUALITY MANGEMENT (T.Q.M.): Is described as an all- inclusive fully integrated productivity technique. It helps to create new markets, expand existing markets and recapture lost markets by utilizing the optimum capability of man, machine, material, method and produces high and uniform quality of products with reduced costs. Total quality control starts from market i.e. from purchasing material and machine and ends in the market i.e. selling the finished products in the market including after-sale service. It includes market analysis, product development, production planning, statistical quality control, preventive maintenance, wastage control, inventory control, cost reduction and after sales service etc. The ultimate goal of T.Q.M. is to increases the quality/cost ration and continuous improvement. It may be done by increasing the quality with same cost, decreasing the cost with same quality and increasing quality and decreasing coast at the same time.<br />The basic quality problem is to set correct balance between the cost and quality i.e. to find out a suitable quality/cost ration for the product which will satisfy the consumer both for cost and quality.<br />Management Responsibility<br />Management Responsibility<br />Section 1<br />PURPOSE<br />The organization’s quality policy is documented and communicated to each person in the organization. The organizational structure, responsibilities and authorities have been described to ensure every key personnel know his job and the same could be cross checked by his higher management.

    SPREADING INSPECTION<br />Following ten points must be taken care of by the cutting quality inspector at the time of spreading.<br />CUTTING INSPECTION<br />Cutting inspection should be on the basis on random sampling on desired AQL. If the lot is passed on sampling inspection then it is send for sewing operation, if not passed the whole lot is re-inspected and rejected parts are replaced by good parts. In cutting inspection there are two types of check BLOCK CHECK & BUNDLE CHECK. Following points are inspected in block check such as Size, Parts, Pattern check, Mis cut, Ragged cutting, Notches, Matching plies.<br />Following points are checked in the bundle check such as Size, Parts, Total quantity, Inspect quality, Defect quality. However it is recommended to check 100% cutting parts under the light box table.<br />SEWING INSPECTION<br />a) The SR. Line Q.I should audit completed finished bundles<br />b) He must select 7 pcs at random from the bundle.<br />c) If the inspector finds defective unit, he will take following steps on operator’s duality Performance Chart.<br />d) He will mark red in the room against date of inspection with defect code and frequency as a symbol for warning and recheck. He will hand over remaining units of the bundle to supervisor for check and taking corrective action.<br />e) He will inspect next three bundles as follow up audit of the same operator and mark yellow in three rooms if no defective units are found in next three bundles. <br />f) He will mark green in the room against date if no defective unit is found in the bundle.<br />g) The inspector will make operators monthly analysis to compare it with tables monthly defect analysis to find out whether there is any lacking in the sewing inspection procedure.<br />h) QC Supervisor Sewing will monitor 7 pcs inspection, whether it is being done properly or not.<br />TABLE INSPECTION<br />Table inspection is conducted by two/three/four inspectors (depends on hourly output) to inspect inside and outside of the garments. They will record hourly inspected garments, defect found, defect percentage; also calculate average defect percentage, quality index of the day and CV of defects. This will help to represent the defects graphically with the help of MIS Inspector. Monthly table defect analysis report is prepared and to compare it with operators monthly defect analysis.<br />TWO HOURLY INSPECTIONS<br />i) It is the responsibility of finishing unit TWO HOUR Q.I.<br />ii) It is conducted every after two hour.<br />iii) Both visual and fit audit is conducted on available garments received. per two hoursat desired AQL.<br />iv) If lot is acceptable than passed for poly packing<br />v) If not return back for correction<br />vi) After correction it is re inspected in the same way.<br />Final Inspection<br />Final Inspection<br />Section 5<br />PURPOSE<br />To establish and maintain documented procedures for final inspection in order to verify that the specified requirements for the product are met.<br />SCOPE<br />This section applies to the product being produced in factory facilities.<br />ACTIVITIES<br />Final inspection is the inspection which is conducted before shipment or buyer’s inspection. It is conducted in two stages.<br />i) Day Final.<br />ii) Lot Final<br />DAY FINAL<br />Day final inspection is the responsibility of factory QA Manager. He conducts this inspection daily on available garments which has passed by TWO HOURLY inspection and is conducted on desired AQL. If it is passed, garments are ready for Central Q C Inspection or Buyers 0 C inspection<br />LOT FINAL<br />Lot final is conducted by Central QA Manager when the lot is passed by Factory QA Manager before shipment or in case any buyer gives the authority to the factory to conduct final inspection before shipment. It is also conducted when buyer’s inspection is conducted before shipment. It is conducted on desired AQL. If lot is passes, they are ready for shipment and placed before buyer's representative for final inspection before the shipment.<br />Garments Inspection Procedure<br />Garments Inspection Procedure<br />STEP-I<br />Inspector should collect the following before going for the inspection.<br />a.

Improper Sealing<br />SAMPLING TECHNIQUE<br />The purpose of sampling is to draw correct conclusion about the population from the sample, now if the sampling is not proper, we may be misguided for taking action on the basis of wrong sampling. Again an inspector cannot check all the items produced in a factory in the whole day, it will cause more man power, more cost, more time and more labour. If proper, sampling technique is used to draw sample, it will not only reduce these factors, will also reduce the monotonousness of the inspector. One of the most important things of sampling technique is the business of the inspector. Inspector cannot take sample as per his wish; he must follow the random number table and probability each item to be drawn is equal. There are various types of sampling of which, sample random sampling, stratified random sampling, systematic sampling are commonly used.<br />SIMPLE RANDOM SAMPLING<br />Simple random sampling is a method of selection n units out of N, such that every one of the Cn samples has an equal chance of being chosen. It is the simplest type of probability sampling and is the basis of most of the other sampling methods. In practice a single random sample is drawn unit by unit. I he units of the population are numbered I to N.A series of random numbers between I and N are drawn with the help of random number table or computer which produces such table.<br />USE A RANDOM NUMBER TO SELECT A SAMPLE <br />Use a random number to select a sample the RAND Corporation of USA has published a random number table in 1955 in the name " A million random digits with 100000 normal Deviates" To select a sample with this table, let us consider we have 750 items numbered from 1 to 750 on each item and we want to draw a sample of size 5. For these purpose we need to select three digits number 001 to 750.<br />First it is necessary to determine the starting point of the table. The random number table contains 50 rows and 50 columns of digits. We are starting from 8th row 39th column from there the first number is 471, 098, 443, 3351 015 it we arrange them in order then 015, 098, 335, 443, 471. Again we want to select sample of seize 10 from a population 500, for this we have to select three digit number i.e. from 001 to 500. Let us start from row 30 arid column 11 then our first number will be 732 but it is not in our serial no so we will exclude it, by going down we will have 752, 640, we will also exclude these.<br />Next 268, 454, 013, 201, 017, 194, 361, 452, 419, 312 excluding all the numbers, which are out of serial. Arranging the numbers in order 013, 017, 194, 201, 268, 312, 361, 419, 452, 454 these are the sample numbers which we want to select randomly. <br />PRE-SHIPMENT SURVEY BY ACCEPTANCE SAMPLING<br />ACCEPTANCE SAMPLING<br />Acceptance sampling is the art or science that deals with procedures in which decision to accept or reject lots or process is based on- the examination of samples. 100% inspection is generally not justified because of time and cost as well as for the shortage of trained manpower. Good sampling inspection, where the items inspected are examined carefully may even provide. Better assurance –of product quality than 100% inspection with carelessness. The purpose of acceptance sampling is to specify course of action not to control lot quality.<br />Acceptance sampling plan merely accepts c, rejects lots. Generally we like to ensure that lots of manufactured goods do not contain an excessively large portion of defective items. This is achieved mainly through the technique of sampling inspection. Acceptance sampling has indirect effect on improvement of quality through its encouragement by high rate of acceptance of good quality and through discouragement of bad quality by high rate of rejection. It also reduces the risk of rejection of good lots and accepting of bad lots on the basis of sample.<br />TERMINOLOGY OF ACCEPTANCE SAMPLING<br />LOTS SIZE:<br />Is the number of units in the lot and is denoted by "N"<br />SAMPLE SIZE: <br />The number of units in the sample and is denoted by "n"<br />LOT INSPECTION:<br />A specific quantity of similar material, or a collection of similar units, offered for inspection and acceptance at one time.<br />SAMPLING INSPECTION PLAN:<br />A specific plan which states (a) the sample size (b) The criteria for accepting, rejecting, or taking another sample, to be used in inspecting a lot.<br />ACCEPTANCE NUMBER:<br />The large number of defectives (or defects) in the sample or samples under consideration that will permit the acceptance of the inspection lot is called acceptance number, and is denoted by "Ac".<br />REJECTION NUMBER:<br />The smallest number of defectives (or defects) in the sample or samples under consideration that will require the rejection of inspection lot is called rejection number, and is denoted by "Re".<br />PRODUCER'S RISK: <br />The probability of rejecting a lot under the sampling inspection plan when the fraction defective in the lot is actually within specified limit is called producer's risk and is denoted by "Pp"<br />CONSUMER'S RISK:<br />The probability of accepting a lot with higher fraction defective than the specified limit under the sampling inspection plan is called consumer's risk and is denoted by "Pc".<br />SINGLE SAMAPLING INSPECTION PLAN: <br />Is the sampling inspection plan in which a decision to accept or to reject a lot is reached after the inspection of a single sample.<br />PROCESS AVERAGE QUALITY: <br />Expected quality of products form a given process, usually estimated from first sample inspection results of past lots.<br />ACCEPTABLE QUALITY LEVEL: <br />The maximum per cent defective that, for purpose of sampling inspection, can be considered satisfactory as a process average is called acceptable quality level anti is denoted by AQL.<br />PROBABILITY OF ACCEPTANCE: <br />Probability that a lot or will be accepted is called probability of acceptance and is denoted by "Pa"<br />OPERATING CHARECTERSTIC CURVE OR O.C. CURVE:<br />A curve showing the relation between the probabilities of acceptance, either lot quality or process quality, whichever is applicable is called O.C. CURVE. The stealer the O.C. CURVE, the greater is the protector to the consumer against accepting a bad lot.<br />AVERAGE SAMPLE NUMBER: <br />The expected value of the sample size required for coming to a decision, i.e., for acceptance or rejection of a lot, under the sampling inspection plan is called average sample number and is denoted by ASN. The curve obtained by plotting ASN against "P" is called ASN curve. Lower the ASN curve better is the sampling inspection plan.<br />MAJOR DEFECT: <br />A major defect is a defect that is likely to result in failure, or to reduce materially the Liability of the unit of product for its intended purpose.<br />MINOR DEFECT: <br />A minor defect is a defect that i s not likely to reduce materially the usability of the unit of product for its intended purpose, or a departure from established standards having little bearing on the effective use or operation of the unit. Minor defects may be classified into two categories; more important minor defects may be designated as Minor "A" and less important ones, Minor "B"<br />CRITORIA FOR SHIFTING TO TIGHTENED INSPECTION:<br />When normal inspection is on effect, tightened inspection to be instituted when 2 out of 5 consecutive lots or batches have been rejected on original inspection.<br />CRITORIA FOR SHIFTING TO NORMAL INSPECTION FROM TIGHTENED<br />INSPECTION:<br />When tightened inspection is in effect, normal inspection shall be instituted when 5 consecutive lots or batches have been considered acceptable on original inspection, criteria for shifter to reduced inspection When normal inspection is on effect, reduced inspection maybe institute when,<br />(a) The preceding 10 lots or batches have been on normal inspection and has been accepted on original inspection.<br />(b) The total number of defects in the samples from the preceding 10 lots or batches are equal to or less than the desired level.<br />(c) Production is at a steady rate.<br />(d) Reduced inspection is considered desirable by the responsible authority.<br />CRITERIA FOR SHIFTING TO NORMAL INSPECTION FROM REDUCED<br />INSPECTION:<br />When reduced inspection is on effect, normal inspection must be reinstated whenever a lot or batch is rejected or production becomes in e-regular or delayed or other conditions warrant that normal inspection shall be instituted.<br />Control of Non-Conforming Products<br />Control of Non-Conforming Products<br />Section 6<br />PURPOSE<br />To prevent the dispatch of non-conforming products to the customer<br />SCOPE<br />This section applies to the products which do not conform the require quality<br />ACTIVITIES<br />Non-conforming goods are identified during the checking of receiving section.

There is no denying the fact that we have been following Quality Control System in the production process since its birth but there might have been differences in those applications in factories. Compiling this quality manual is a humble effort to put almost all necessary details of Quality Control System to ensure that all our factories have a written Manual/ Guideline in black and white to follow. In the beginning we will not concentrate on the statistical Quality Control System. We will follow this after a while when we have enough and required manpower to exercise that. Any positive inclusion in this manual which will help the factories in improving quality is always welcome; but has to done with prior approval from the Managing Director. We all need to educate and train our work force in line with this Quality Manual to try and streamline our quality system. Our united and sincere effort only can help to improve in the sector of quality.<br />
