An observation toward Computer aided processes in Garments production. Comparison and analysis of CAD/CAM Software in Bangladesh

This research paper inquires about different attributes of Computer-aided processes in garments production. This perspective Research was done by our courageous team from 2021 to 2022. It reveals adequate information on the Garments industry's Intension and criteria for choosing CAD/CAM software. For the sake of this Research, we visited more than 600 industries to gather raw data; Every Industry tried to attend this Research from a different region of Bangladesh willingly. After collecting all raw data from the garments industry. The data of the Garments industry was coordinated by Excel program. Consequently, the data was analyzed and implemented statistically to identify the Garments Industry attribute for satisfaction with CAD/CAM software. This process also detects many challenges and defines and advises a proper solution to the problems that the Garments industry is facing in the current situation. This research paper demonstrates adequate information about the Garment's criteria and demand in purchasing garments Computer-aided software.


Data assortment and Inspect
There were 600 users and 600 buyers attending this research experiment; most were aged 18 to 55. Most respondents are Bangladeshi users and foreign buyers [14]. Most of the experiments and interview locations were chosen at the industry lab, where engineers from different industries use their CAD and CAM software [9].

Final Data Scraping and Analysis
Final Data scraping and analysis was a very challenging part of this Research. Because we have focused on 2 sites-1] User experience and satisfaction 2] Buyer criteria and demands Data analysis is regulated through the User intention and faculty to use specific software in fewer worthwhile groups. In the same way, it analyzed the Buyer's demands. The statistical data analysis succeeds using the process of an open coding system. Consequently, this method of data analysis permits us to illustrate the actual data [6] Magnitude and measurement For data collecting, we tried to make a sample size of 600 Industry Users for respondents we took to ensure adequate ratios where most respondents are directly CAD and CAM software experts. On the other hand, we have collected information from more than 600 buyers about why they require and Satisfy with specific software [4]. Eventually, the authors can collect Data and information from respondents from 5 different Industrial areas such as Dhaka, Tangail, Gazipur, Narayanganj, and Narshingdi [2]

Data manipulation and Integration
Data integration is a vital element of quality research, where this process considers several analyses with some data points [15]. It controlled ideal and correct decisions with decreasing misleading data. This process can evaluate and recognize data where the specific statistics come from respondents. That is why this combination is implemented for quality results [6] Revista Innovación y Software Vol. 4 In this analytics, two specific charts represent the priority level of the different users with some attributes. However, the line and bar charts represent exact data and the same value differently. The Research Determine that the majority of the Software user give first preference to production and second priority to the quality of the Software performance and production. According to the linear priority level, this is clear that the highest preference is production size with minimum time. So every user of an industry chooses the software with Bulk production to save valuable time. The following Line chart shows the highest priority for software production, where first and second priority accounted for 71.50% and 69.08%, respectively. The bar diagram clearly expressed that the price, speed, and mistake are the maximum preferences for second priority. The following line diagram shows the volume of each priority in percentage. This bar chart is illustrated the priority level of software user considering with some attribute. However the following bar diagram created with almost same data and value. Here, in the upper following chart Production = the amount of production per hour or per unit time.
Price = how much needed to buy a software/ the amount of money.
Speed= the software flexibility and how much it faster.
Quality= the quality of the design and final production Mistake= the possibility of mistake when a software user working on a design.

Quality Selection of CAD and CAM software
For quality selection, Firstly, we have to choose five attributes, such as time to make a design, the software's brand, the software's price, the possibility of Mistakes when making the design, and the complexity of the software. A user is keen on software quality, which most users consider a maximum priority as the software brand and time for making a design. The priority accounted for Brand, Time, price, mistake, and complexity, respectively, 37%, 35%, 15%, 7%, and 6%, and it was followed by just 25%, 30%, 20%, 10%, and 15% for second priority. So, the user is Possibility of the mistake and Complexity of software in case of quality selection. The possibility of mistakes and complexity of software is almost identical for all types of software. People always try to focus on the brand and time to make a design. The volume of priority for quality is shown individually in the following bar chart and pie chart.  Most of the Buyers intended to Use branded and well-reputed company software rather than the price and speed of the software. However, the highest proportion of buyers chooses to use a software brand and the production quality, accounting for 60.59% and 39.41% for priority, followed by just 41.27% and 58.73%, respectively, for second priority.
Among them, Buyers avoid the price of the software and how much faster it is. Buyers are confident that another software attribute will be better if the brand is well-reputed. That is why every Buyer avoided the price and faster properties of the software. So a buyer chooses the best-branded software like Lectra or Optitex software. However, Buyer focuses on Lectra software in the first place. The software selection priority percentage is shown in the following bar chart.  respectively, 50%, 52%, 54%, 56%, 57%, and 59%. From the line chart, it is found that buyer awareness was maximum in 2016 when the company used the software. However, industry awareness was lower than buyer awareness. However, gradually, industry awareness surpassed buyer awareness in 2021.

An actual Garments order sheet for analysis:
For the research purpose, we have the carry out a real test with a Buyer order sheet. Most of the respondents used their preferred software with specific measurements. The buyer KIABI company sends a requirement for a half shirt. The specific measurement below is in figure 1; on the other hand, figure 2 represents the half shirt's specific design style, where more than 600 respondents were directly involved with making this half shirt design.
We carefully observe the software performance when the software user is trying to make a design. Our observation includes some basic questions and parameters. Such as-1. How much time is required to make this specific design?
II. The possibility of mistakes was carefully observed.
III. The production ability was calculated with this software.  On the other hand, Optitex is also better for medium-quantity production. The performance of using Gerber software is fewer users than in small factories. But for small production, this software suits. During our research we have tested more than 600 user with different measurement. The following figure 1 represent the measurement chart for the half shirt of KIABI company.

Automatic template design system:
An automatic template design system is a process where a user is capable of making a CAD/CAM design with a previously created template. This Template provides the facility to make a garment design easily. This automatic template design system allows users to re-edit the design with their criteria [16]. A designer can re-edit the measurement also. So the time to make a design is less in this automatic system. The purpose of discussing these properties is to make it clear which software consists of the highest facilities.
Where Lectra has a rich resource of automatic templates because Lectra is a software created by a well-reputed company, they are trying to develop the software within a period. They updated the software gradually and added a lot of automatic template designs. Optitex software recently added some automatic template design systems. Nevertheless, this is less effective compared to Lectra software.
On the other hand, Gerber still has backdated software compared to Lectra and Gerber. So this software has no resources for an automatic template design system.

Final analysis and discussion:
Now the final analysis is done from previous preliminary Research. The final analysis represents the actual parameter and Attribute, which is why a company chooses a specific software. The following table is more complex than the whole Research. Where it represents the different attributes, this specifically represents why companies choose software for their industry [12] . The positive Attribute of Lectra software is the quality of design, the possibility of mistake, and the production rate, which accounted for 98%, 8%, and 99%, respectively. Where Optitex is accounts for 80%, 15%, and 70%, respectively. The Gerber also accounted for 75%, 20%, and 50%, respectively. The possibility of the mistake of creating a design is less in Lectra, which plays an essential role in choosing Lectra.
However, Gerber and Optitex are faster, have minimum complexity, and fewer prices. Where Gerber accounted for 90%, 70%, and 25%. On the other hand, Optitex accounted for 80% However, Optitex and Gerber have many more limitations than Lectra. The following bar chart represents the different Attributes with different software with the following data  On the other hand, the production rate is also maximum in Lectra software. However, the speed, complexity, and price are maximum, negatively impacting Lectra software. Nevertheless, the design quality, the possibility of the mistake, and production accounted for 98%, 8%, and 99%. The price of the Lectra software is maximum, accounting for 10,00000 to 15,00000 taka. However, the price of the software is the too high price. However, the other Attribute plays a positive impact. That is why the user has ignored the price of the software. Lectra software also has complex and slower than other software.
So the production and design quality rate hit the maximum, positively impacting Lectra Modaris software. The possibility of a mistake is 8% means Lectra Modaris software has a minimum possibility of mistakes. The other significant factor is that Lectra software is the leading template system, which helps a user make automatic software, the most extensive facility for making a design quickly. That is why Lectra choose a maximum number of big industries in Bangladesh. Owing to compatibility, the production of the software plays a vital role in influencing the user's tendency to buy CAD/CAM software.
For the medium industry, they focus on some attributes for their company satisfaction. So every medium-class factory intended to buy Optitex software. Optitex is software that is faster than Lectra software. Complexity is also lower than the Lectra software. The price of the software is low compared to Lectra software. That is the way the 3 attribute of the speed of the software, complexity, and price, which is accounted for 80%, 75%, and 35%, plays an essential role in choosing Optitex software. For medium-class factories, the production size is less. So they try to ignore the production size.
For a small factory, they always preferred to buy Gerber software for their satisfaction. Gerber is enough to meet their criteria, also. Where the small factory ignored 3 attributes such as quality of design, the possibility of mistakes, and production size; on the other hand, they focused on the software's speed, complexity, and price. Where speed, Moreover, the complexity of the software is less. So it is pretty easy to learn and use. To recapitulate, 59% of users prefer to buy Lectra Software, 25% prefer Optitex software, and 16% prefer to use Gerber software. There are 3 types of Gerber software available. Such as gamine, bock, Emma, Etc. Every Buyer wants faster and quality software that involves the proper time delivery.
Buyer also focuses on attributes such as quality and brand, accounting for39.41% and 60.59% for priority, followed by 58.73% and 41.27% for second priority. However, the Buyer has no choice about the price of the software. Because of that, there is no influence of the price upon a buyer. [6] .
To encapsulate considering all the properties user is intended to buy 59% Lectra, 25 % Optitex, and 16% Gerber.
