TNA is a popular approach used in the garment manufacturing factory is a strategy to follow and follow important milestones of the preproduction process to confirm timely supply within the scheduled delivery date. Garment Pre-Manufacturing and Merchandising activities. Although some works are depending on each other, others are distinct. Every RMG company occur great care during order planning. Every small detail is built into the planning method. Creating a TNA schedule is not just about entering the name and duration of activities in tabular shapes; it scientifically determines the schedule of the work, logically evaluating the previous and successful activities. TNA schedules have short-term and long-term plans so be careful (Uddin et al., 2020). 

Strawberry cutting methods used in the industry use straight knives for straightening cutting and fabric lying in one method is considered as non-invaluable process exclusion in the development of the method only. The research department endows with the productive process of cutting. It also decreases the waste of non-productive activities in the cutting section that can be avoided which can reduce lead time as well as period and space. Therefore, the cutting method in the factory is one of the key values (Jacobs-Blecha, 1993). The cutting zone of the garment manufacturing industry provides the necessary cutting panels in the sewing section for production modules. The cutting panel has several functions in the cutting section like fabric spreading, cutting, numbering and bundling. (Karim et al., 2019; Upendra et al., 2013).

While there are various prices involved in reducing costs by internally wasting costs by a factory, avoiding and upgrading defective work will result in minimal archiving (McClellan et al., 2001; Mohibullah, 2016). The RMG factory has three main sectors namely cutting, sewing, and finishing (Islam et al., 2013). 

A TNA schedule is one of the key valuable com-munication tools that prove that it is effective for this task. The chart made of the time frames (main ones) listed for each work in the plan and these functions require to be carried out in a timely manner. The aim of the TNA is to check at regular intervals, once a week to see if the plan is being implemented adequately. The more smooth the reviews, the sampler it is to accurate the deviation. TNA is commonly effective when a buyer needs to know the current status of an order execution. Usually TNA does not base on the textile used in the product, such as woven or knitted. TNA largely based on the specific approach flow of any order, the requirements of the machine, and the available making capacity. The TNA designed Cutting schedule and the former factory date are two very important dates. Most garment companies open thin manufacturing to upgrade their steps. Progress in timely delivery progress is a field of work that they focus on under the guise of inferiority (Kuma, 2017; Paneru, 2011).

The TNA schedule is one of the key important approaches for managing time. In the field of garment making, each requisition is no less than a new project for the merchant as it involves different functions and use of different resources in different time periods from the time the order is received to the time it is comp-leted. Like process numbers, lots of the people are also attached in completing an order. Commonly each order approach and time is same in terms of demand. Thus, a completed plan with properly defined responsibilities is definitely needed to fulfill each order on time. A TNA schedule called the ideal date/period in which the main works of an order should be in contrast to a scheduled distribution window.

This plan sheet is popular as TNA and once a TNA time is created, it can be simple for merchandisers to "make a list" of each day and take it step by step. It can be carrying out on a timely basis to area whether an requisition is on zone as per the TNA schedule or it will be delayed.

TNA plan for the T-shirt making Order in Knit Garments Industry. TNA or T&A Plan is an important tool for a merchandiser to enlist his day-to- day activities or to enlist the different operations involved in the method of completing an order. 

TNA is the key significant work for timely delivery. TNA, a popular approach used in the garment manufacturing factory is a strategy to follow and follow important milestones of the preproduction step to make ensure timely supply within the scheduled delivery date. Garment Pre-Manufacturing and Merchandising works Person in a company have more than one activity character, although some activities are parasite and obey each other, others are individual. Every RMG factory takes great care during order planning.

Table 1: RMG factory activity during order planning

Every tiny detail is built into the planning rule. Creating a TNA schedule is not just about entering the name and duration of activities in tabular shapes; it scientifically determines the schedule of the work, logically examining the previous and successful acti-vities. TNA calendars have short-term and long-term plans so be careful. A TNA schedule is one of the major significant communication tools that prove that it is effective for this task. The chart made of the time frames (main ones) listed for each work in the plan and these works require to be carried out in a timely manner. The aim of the TNA is to check at regular intervals, once a week to see if the plan is being implemented satisfactorily. TNA is mainly effective when a buyer requires knowing the main status of an order execution. 

Merchandisers usually plan the order in a data-sheet, setting the schedule of the main processes in the first column and the planning date for each step in the next column. This plan sheet is popular as TNA and once a TNA plan is created, it can be simple for merchandisers to "make a list" of each day and take it one by one. It can be achieved on a timely based to area whether a requisition is on zone as per the TNA schedule or it will be delayed.

In order to build TNA following mentioned data must be accessible –

  Step flow of an requisition with the table of task which require to be done

  Making extent of cutting, packing, sewing, washing, Checking, and finishing

  During sewing lot wise and sample wise capacity

  Escort time of work, e.g. raw component set time, sampling set time, etc.

  Set Shipment schedule, and planned ex-factory time

Usually TNA does not hold on the textile used in the product, such as woven or knitted. TNA largely hang on the desire plan flow of any order, the requirements of the machine, and the available yield capacity. The TNA Plan Cutting time and the former factory date are two very important dates. Before making TNA Plan of knit fabric garments industry, Consequence of nume-rous Types of Activities knit Garments industry. 

3.1 Sampling - Sampling is the key important task and therefore needs to be planned very carefully in TNA, some sampling steps are very necessary so any deviation or late in it will act on the whole TNA. Example- Proto Samples, Fit Samples, AD/Photo and Shoot/deliveryman garment, Size-Set Sample, GPT Sample, Pilot Run, Pre-Production Meeting and Sample, Production Sample Top.

3.2 Textile and Accessories Sourcing - Textile and accessories sourcing is a very labor intensive step which includes desk weaving and lab-dip approval, accessories and art work approval, FPT consent. Example - Fabric Approval, Trimming and Artwork, and Textile Performance Test.

3.3 Production - The most valuable part of any TNA is the actual production. Many of the time, TNA is pursued with PCD in mind. The sourcing division plays an important role in achieving timely PCD, as the lead period for accessories and textile production and existing for sample made are regulated by this section. Desire lead time and adequate buffer should be kept for sourcing when making TNA. 

3.4 Production initiate and end dates - These two dates depend purely on shipment schedule and production capacity. Manufacturing should start as early as the PCD is acquired and the pilot runs and PP samples are approved. Any deviation from this time affects the subsequent top garment submission time and shipment schedule. The period of days needed for production is planned by the capacity assigned to that desired product or the schedule of days available for real shipment date.

In this study, TNA Plan of knit garments industry was studied. TNA is the most valuable work for timely delivery. If a merchandiser is able to obey the TNA actually, sending the garment as per the schedule will not be a big challenge. Garment making is not a one man show business but a teamwork involving lots of people, companies, suppliers, buyers, sub-contractors and producers. In addition, all work must be done within a certain timeframe for the timely delivery of the garments. TNA plan is helps to execute the whole works in knit garments industry according to lead time. Without TNA plan not possible to execute the buyers order on time. Two TNAs this was also a regular work; one with some of the major key activities proposed by the buyer and the other one with a huge number of other internal micro activities (internal activities). It is mandatory to decide that all activities should be in the TNA calendar.
