In the previous article, we talked about “Unitex underwear manufacturing-lean production and quality management” and “How to Improve Lean Production Management Level For Unitex Underwear Sourcing Programme?”. Lean production is very important to improve the management of an enterprise. For our supplier of Unitex custom underwear suppliers, it can make the production factory better avoid waste, save more costs, and thus generate more favorable income and more efficient profits. At the same time, it can better start from the source, make management and production cooperate with each other, and better control the whole process, thereby improving the quality of underwear products. Only by improving the level of production management and thus improving the quality of our underwear products can we promote the rapid development of our enterprise. And owning the high quality boxer shorts underwear products is the solid foundation for our enterprise to survive. 

So, what are the common problems in the implementation of lean production management in enterprises? Lean production is currently very popular in enterprise management, but there are also companies watching. Lean production is an advanced production method that can be produced according to market demand, and can reduce waste and inventory, reduce production costs and make enterprises more competitive in the competition. However, many enterprises still have many problems in the process of implementing lean production, which are manifested in two aspects: 1. Surface problems (appearance of problems); 2. Potential causes (direct causes, intermediate causes, root causes, etc.).

Lean Production Management FAQ

 

  1. The concept of managers and operators has not changed: the concept of relevant main executors has not changed, and the coordination is not in place, and it is difficult to achieve the expected goal of lean production.
  2. Didn’t find a good entry point: Find a good entry point for introducing lean production, with the easiest and most obvious improvement results to make everyone feel the benefits of the new way of working, then change consciousness and build confidence.
  3. Quick success and instant benefits: The idea of “immediate results” and “great results” in a short period of time and major changes are not in line with the principle of continuous improvement of lean production.

 

  1. Prototype area first: formulate a detailed trial plan, work first in the form of the sample area, and improve the problem points during the sample operation, and then extend it to the whole plant. In the underwear sourcing industry, it is also called the first sample. Do a good job of the first sample, find problems and improve them, which can well avoid some unnecessary troubles in bulk production.
  2. Lack of overall cooperation: It is believed that the implementation of lean production is only the responsibility of IE engineers and has nothing to do with other units. For example, if procurement, logistics, engineering and other units cannot fully cooperate, even if there is a good plan, it is only a “short-lived “, unable to continue to exert the effectiveness of lean management.

 

  1. Too much investment: Improvement should be based on the principle of not spending money. Don’t think of investing in new equipment and new technologies as soon as you encounter problems. You should try to avoid investing a lot of money, and you can improve on existing facilities or foundations, maybe also the best solution.
  2. The implementation process stagnates when encountering difficulties: “Three cobblers are better than one Zhuge Liang” to brainstorm and prepare multiple solutions. Open your mind, absorb different opinions, don’t explain why you can’t do it, and figure out how to do it. Don’t wait until it’s perfect, you can do it with five points of confidence.

Buyer Questions

MOQ, lead times, certification and trading terms

For a small set of recurring reasons: the line is measured on output rather than on first-pass yield, batch sizes are set by the machine rather than by demand, and the corrective action loop is not tracked. Each of those is a management decision rather than an equipment one. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

Because output counts everything that leaves the line, including the pieces that will be reworked or rejected. First-pass yield counts only what was right the first time, which is the number that reflects the process. A line can hit its output target while generating rework faster than it should. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

They build work-in-progress, which is inventory and carries the same cost as finished stock — space, handling, and the risk of a defect being discovered late. In cut-and-sew, batch size is often set by the cutting equipment rather than by demand, which is a planning decision rather than a technical constraint. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

In the corrective action plan. An audit finding that is recorded but not tracked becomes a repeat finding, and the improvement that was made to close it drifts back. Tracking closure is what converts a finding into a change. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

By asking them to describe their last three improvements and what measurably changed as a result. A supplier with a working system can answer with specifics; one that has adopted the vocabulary without the routine will describe the principles instead. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

First-pass yield, lead time and rework rate rather than units per hour on its own. The first three describe the process, while output on its own describes the volume that passed through it — which is why a line can report a good month and a poor one at the same time.
