Management is one of the important things to do as a form of data collection and control so that an activity runs smoothly with minimal complications. The importance of management science lies in its ability to assist organisations, both large and small, in adapting to environmental changes, identifying and exploiting opportunities, overcoming challenges, and achieving short- and long-term goals. 

Effective management can increase productivity, minimise costs, improve the quality of products and services, and ensure employee satisfaction and well-being. In addition, in the context of globalisation and evolving technology, good management skills are crucial to compete in an increasingly competitive and dynamic market.

Of course, the public does not forget the incident of the explosion of the Galaxy Note 7 smartphone in 2016, at that time there were mass calls and refunds that occurred due to negligence in the assembly of the device which resulted in a decrease in sales of the product. Therefore, in the manufacture of devices, especially electronic devices that are used every day, there is a need for Quality Management in addition to ambitious Marketing Management.

In management science, of course, there are different branch disciplines, two of the various branches of Management science are Management related to monitoring the Quality (Quality Assurance and Quality Control) of a production item and Marketing Management which functions as a process of planning, implementing, and controlling marketing strategies to achieve organisational goals through fulfilling customer needs and wants effectively and efficiently.

In production activities, there is an activity to monitor the safety of a product so that it can be accepted as safe and in accordance with consumer expectations, namely Quality Control and Quality Assurance. Quality Assurance is the initial stage of the overall monitoring of a product within the scope of Quality Management. 

Quality Assurance functions to monitor the initial stage of a production before there is a completion stage such as post production checking, Quality Assurance also functions as a prevention of defective material goods or plan errors. In Quality Assurance, there is an evaluation of the production plan which includes reviewing the design of a product, monitoring raw materials that will be used in product management and internal audits that function as verification and monitoring of production in accordance with established SOPs. 

Quality Control is a process carried out post-production where there is monitoring of goods after going through the assembly stage. Quality Control is in charge of handling and repairing several units of goods that have experienced defects after post-production so that they can be reviewed and repaired. Quality Control is also tasked with maintaining indirect relationships with consumers through the implementation of the Pareto Effect principle or the so-called 80%/20% principle where 80% of the side effects of reviews of failures can come from 20% of users who have significant social representation. Quality Control also has a mandate to repair products that have been recalled in order to find solutions to problems that arise so that future products do not experience similar technical problems. 

After the checking process for safe use by consumers by the Quality Management department, a product will go through the marketing stage. Marketing Management is a process that involves planning, implementing, and controlling marketing strategies to achieve organisational goals by understanding and fulfilling customer needs and wants effectively.

Through Marketing Management, a company can study market demographics along with the appropriate price to be addressed to prospective buyers to suit the needs of the public along with market pricing regulations (as well as taxes). In the work unit carried out, of course, a company applies SWOT in various fields, this does not exclude marketing because in the game of the market world a producer must be able to capitalise on an opportunity according to the weaknesses and strengths of a product in a particular market segmentation.
