Introduction

In today's highly competitive global market, manufacturing and service industries are constantly required to innovate and improve their business strategies to maintain their existence. One of the key aspects in improving products is the quality of characteristics that are in accordance with consumer needs. Companies must be able to create quality products to stay ahead of the competition. This article discusses the application of Quality Function Deployment (QFD) and Design Structure Matrix (DSM) in determining process design priorities, using PT. Inti Jaya Metals as a case study.

Background

PT. Inti Jaya Metals is a company engaged in making spare parts for machines, particularly those used in oil palm factories. The production process at this company involves the smelting of cast metal Iron and produces various products such as bushing cast iron, impeller, fire grate, baffle plate, fire door, pulley, gear, and dust collector cone. However, observations show that companies face serious challenges related to product quality. Complaints from consumers related to inappropriate sizes due to the high level of depreciation and product durability that is less than optimal are the main focus. The most common product is the Dust Collector Cone, an important component in the water dust filter that functions to neutralize fine dust during the production process.

Quality Problem Analysis

Complaints to the Dust Collector Cone indicate a mismatch between the products produced and consumer expectations. This is a signal that there are deficiencies in the design and production process that needs to be identified and improved. Product quality is often influenced by several factors, such as the selection of raw materials, manufacturing processes, and quality control during the production process. To overcome this problem, the right approach is to use two methods, namely Quality Function Deployment (QFD) and design structure matrix (DSM).

Quality Function Deployment (QFD)

QFD is a method used to identify and define consumer needs so that it can be translated into product technical specifications. With QFD, companies can better understand what features are most important for consumers and how to increase products to be in accordance with their expectations. QFD is a powerful tool that helps companies to:

Identify customer needs and expectations
Translate customer needs into product technical specifications
Prioritize product features and characteristics
Improve product quality and reduce defects

Design Structure Matrix (DSM)

DSM is a very useful tool in managing complexity in product design. By using DSM, PT. Inti Jaya Metals can map the relationship between design elements and production processes. This allows companies to identify potential problems in workflows and prioritize areas that need to be improved to improve product efficiency and quality. DSM is a powerful tool that helps companies to:

Map the relationship between design elements and production processes
Identify potential problems in workflows
Prioritize areas that need to be improved
Improve product efficiency and quality

Solution and Implementation

In practice, the application of QFD and DSM at PT. Inti Jaya Metals can be done with the following steps:

Identification of Consumer Needs

Conducting surveys and interviews with customers to collect data on their desires and needs of Dust Collector Cone.

Quality Mapping

Use QFD to translate customer needs into technical specifications. This includes size, durability, and other quality factors desired by consumers.

Process Analysis

Use DSM to map the relationship between design elements and production processes. Identify which elements have the greatest impact on product quality.

Quality Control

Applying a strict quality control system during the production process to ensure the final product is in accordance with the specified specifications.

Conclusion

By applying these two methods simultaneously, PT. Inti Jaya Metals are not only able to overcome existing problems, but also improve the quality of the product as a whole. In addition, companies will be better prepared to compete in the global market with more innovative products and meet consumer expectations. This effort is a strategic step to maintain and improve the competitiveness of the company in an increasingly fierce competition.

Recommendations

Based on the case study of PT. Inti Jaya Metals, the following recommendations can be made:

Companies should use QFD and DSM to identify and prioritize consumer needs and product design elements.
Companies should apply a strict quality control system during the production process to ensure the final product is in accordance with the specified specifications.
Companies should continuously monitor and improve their product design and production process to meet changing consumer needs and expectations.

Limitations

This study has several limitations, including:

The study is based on a single case study, PT. Inti Jaya Metals.
The study only focuses on the application of QFD and DSM in determining process design priorities.
The study does not consider other factors that may influence product quality, such as raw material selection and manufacturing processes.

Future Research Directions

Future research directions include:

Conducting a larger-scale study to validate the findings of this study.
Investigating the application of QFD and DSM in other industries and companies.
Exploring other methods and tools that can be used to improve product design and production process.

Introduction

In our previous article, we discussed the application of Quality Function Deployment (QFD) and Design Structure Matrix (DSM) in determining process design priorities, using PT. Inti Jaya Metals as a case study. In this article, we will answer some frequently asked questions (FAQs) related to the application of QFD and DSM in process design.

Q: What is Quality Function Deployment (QFD)?

A: QFD is a method used to identify and define consumer needs so that it can be translated into product technical specifications. With QFD, companies can better understand what features are most important for consumers and how to increase products to be in accordance with their expectations.

Q: What is Design Structure Matrix (DSM)?

A: DSM is a very useful tool in managing complexity in product design. By using DSM, companies can map the relationship between design elements and production processes. This allows companies to identify potential problems in workflows and prioritize areas that need to be improved to improve product efficiency and quality.

Q: How do QFD and DSM work together?

A: QFD and DSM work together to identify and prioritize consumer needs and product design elements. QFD is used to translate customer needs into product technical specifications, while DSM is used to map the relationship between design elements and production processes.

Q: What are the benefits of using QFD and DSM?

A: The benefits of using QFD and DSM include:

Improved product quality and reduced defects
Increased customer satisfaction
