MANAGEMENT QUALITY

There are many tasks to perform managing quality such as process strategy, location strategies, layout strategies, human resources, supply- chain management, scheduling, and maintenance. Each strategy as we mention above will be more detail in other specific part in this report. In this part of the case we mention about quality in East Asia company; we just focus on International Quality Standard. As we know, there are tow ISO 9000 and 14000, in East Asia company, they just apply ISO 9000. Now how we can understand what ISO 9000 is and how East Asia can apply it. What is ISO 9000? A set of quality standards developed by the international standards Organization (ISO) such as Quality management system, Management responsibility, Resource management, Product realization, Measurement, analysis and improvement. In East Asia how they can apply ISO 9000 It is very hard to go detail in this part, we just mention some main idea about ISO in Ton Dong A.

PROCESS STRATEGY 1.

GENERAL

The production line is WETLUX technology. The factory has prepared to build a new production line with NOF technology. Productivity: 5000-6000 ton/month (the ratio is 80% Zinc plated Steel plate, 50% Color plated steel plate. Recently, the ratio is changed to 50% plated Steel plate and 50% Color plated steel plate. And last month, the ratio of production is that the percentage of color plated steel plate is more that one of zinc plated steel plate. ) Effective output is 30% or 40% of design capacity. Instruction includes 4 independent production lines. Maybe the product of this production line becomes raw material for another one (internal traffic)

2.

DETAIL A) GALVANIZED IRON There are 8 sections in Zinc plated Steel plate production line

Step 1: Checking input Materials: From production schedule, checking the specification of materials and define quantity. Weighing the Black Sheet bundle, writing and recording the data such as: standard weight, actual weight, suttle, specification and mode into the quality logbook of Black Sheet. Checking the quality: Round check: specification, place of origin Unpacking the bag, checking inside materials. To some bundles which are not enough equality such as : distorted, exothermic, iron-mould ….they will be carried out without producing. In the production process, workers often monitor the quality of Black Sheet (level of fertile, exothermic, rupture…) then record in the quality logbook of Black Sheet.

Operations Management Report Step 2: Direct feed material continuously: If the materials are enough quality to produce, they are inflow exhaust system and hood up with the first bundle to provide continuously for production line Step 3: Deoiling and Pickling:

Checking input Materials

Before Steel plates was entering to plate, they had had to through the deoling and pickling section, this section has 4 parts : Using chemicals to deoil : First, the Sheet band must go through the cistern concentration from 23 to 40, the temperature is 600C – 800C here with steam, then next to two flushing chambers. Those flushing chambers is including : pump high –

Direct feed material continuously

pressure team system and small detergent from the cistern. It atomizes two faces of black sheet bundle; use the crane to cleanse deoiling parts. It continues going through the hot water flushing chamber (600C – 800C)

Heating the sheet

Plating ZINC

to reclean some dirty elements on Sheet. After that, sheets are gone into HCl bath with 10% - 20% strength. This is

Operations Management Report Step 5: The process of plating ZINC:

Input materials

With the temperature of 1800C – 2000C, sheets is entered soldering flux chamber (Ammonium Chloride, antimony, aluminum) to flush, increase the brightness and mechanical behavior of materials… Then, sheets are gone through zinc chamber, second to radiator grouping to finish this process. Step 6: The process of Cooling:

Deoiling and Pickling

The air duct system and booster perform this process. But after cooling sheets with air duct system, the temperature of sheets still are high. So they is bathed with a water chamber, here the temperature is slow down 600C-800C. And the water chamber makes sheets clear more. Step 7: Surface Passivation:

Plating Zinc

Here, sheets are dipped in chromium chamber with the 3 – 7 strength and the temperature is 550C-600C. Sheets are overlapped by a protective coating chromium against to pickling. Then they are dried by a couple of rubber crane before come to next section. Step 8: Packaging and Inventory: Steel plates are categorized with the level of A, B, C of management department. After making steel plates become bundles, they are

LAYOUT STRATEGY

Today, the East Asia used product-oriented layout for production because characteristics of each products. Factory has six departments in which have two Galvanized Iron worksation and one Pre-painted Galvanized Iron workstation. Next year, Factory will have more one

Galvalume (Zacs) workstation. There are six departments of factory 1. Operation Management Centre 2. Supply material 3. Workstation 1 produces Galvanized Iron 4. Workstation 2 produces Galvanized Iron 5. Workstation 3: Pre-painted Galvanized Iron 6. Inventory Product-oriented layout had been used because factory makes focus only two kinds of product that they need production is stable and high efficiency.

Page

13

Operations Management Report Advantages and disadvantages of this layout

Product-oriented Layout Advantages •Low variable cost per unit •Low material handling costs •Reduced work-in-process inventories •Easier training and supervision •Rapid throughput

Disadvantages Higher capital investment •Special equipment •Any work stoppage stops whole process •Lack of flexibility •Volume •Product

The product manager said that factory faced with area problem and they can’t expand area of factory. Supply material area and inventory is often in minimizing stable that mean company expense more money. Area problem is also reason that the distance between departments is still so far and movement components still not convenient. For instance in case, in workstation 1, finished product must bypassed new-come to inventory. Although factory has many difficult but East Asia intend to make innovation of layout so that production is more efficiently and reduce cost.

VII.

HUMAN RESOURCE AND JOB DESIGN

The Human Resource strategy of East Asia based on the Annual Strategy of the company – when the company defines its main strategy for the year – they will define the number they want to have in their human resource based on all of the related sides: Marketing, productivity …. After that, a process is opened up, they will search to the application pool in some public places like job fair, the job centre…, then they will get the application, after screening the application, the second round is the interview round. The interview round will also be the last round of the selection process of East Asia. All of their process about Human Resource, not only selection, but also others like training, incentive program … followed the government process.

Page

14

Operations Management Report For training, they have 2 levels, the first one for low-level employees; mainly they will do training on the job, and the former train to their new members, or their successors. This kind of training is suitable for East Asia as the low level because it can save the cost, also reduce the training time. Mainly the low-level employees of East Asia have low educational level, with not high salary, and do simple processes work in the machine. With high level employees, mainly high-level educational level, from business field or technical, East Asia have programs for them to educate them more about knowledge and train more skills needed. Sometimes, they send some of their technical employees to near country like Singapore and Malaysia to learn more about the modern techniques in this country. East Asia follow the Employment-stability process, that keep their employees constant with time, and expand their employees by around 10-20% per year. Their Standard work schedule is 3 periods (8 hours per one period) per day (24 hours per 24 hours), with this working time, they can produce with all of natural providing time and take advantage of the running of machine to keep the work all the time. The working rules of East Asia are clarify and put in the information board of each machine – then the employees can follow their period and do needed things with respect the rules to make the process run well time by time. They have 3 types of machine, produce differently, around 7 to 10 to 20 employees per machine, depended on the complex level of the work. The work in East Asia, as watched, can be clarified to 2 types, high-level and low-level. In Low level, they do the work with very high specialization – the low-level employees work in process together with the machine, their works require very accurately and somehow simple, that why their employees don’t need to have average education level. With high level, they work as administrative works and high level techniques and business, still with specialization but more autonomy than low-level, their education and training are also better. The psychology components of job design for low-level employees are rather clear. Skills variety is not so much because the job is specialization. The job identify is clear, also trained carefully on the job. Job significance is also clear, each employee has his

Page

15

Operations Management Report responsible, and stated clearly in the information board, working rules, and process identification. Job autonomy and feedback on the job is not much, due to the job characteristics. Motivation system of East Asia is based on productivity and some gain sharing and profit sharing of the company. The ergonomics and work method in East Asia is also rather good. Their process is semi-autonomic, the employees just special in their works beside the machine. Work environment in East Asia is somehow rather good, with wide and high factory. But the noise in the machine is so high, very head-ache sound. The dust from the machine is not so much due to the good technology of East Asia, it’s a plus signal for work environment.

C.

PART III: MANAGEMENT OPERATIONS

VIII.

INVENTORY MANAGEMENT AND SUPPLY CHAIN MANAGEMENT

Inventory is a very important part of any company and so does East Asia Company. It helps the company flexible to keep pace with customers’ needs and perform production process effectively. In this part, East Asia Company’s inventory is discovered in main terms below. The method used to compute the inventory level that the company apply is base on production volume, sale volume and inventory capacity. After all factors are balanced, the backward calculation is done to find out the amount to keep in inventory. The goals are to minimize the cost and satisfy the demand such as reduce holding cost – the cost of carrying inventory over time. The company tries to get stock safety and avoid stock outs. The company invests a lot in equipment and management tools. The setup cost is high. Once a year, each chain of production equipment is repaired and maintained for one month according to ISO 9001-2000 quality management standard. Record and cycle account: Each roll of material or product is verified carefully and pasted a certification sheet of characteristics and codes to manage. The manager goes around checking and recording them. Management the inventory is done by software. The company has invested in Lac Viet software company 300 million vnđ for operation management software. Reorder: the company order in two sources: domestic suppliers (30% raw material demand) and foreign suppliers (70% raw material demand). Domestic company is Phu My steel company. This company uses Italian technology, so that their products have high quality,

Page

16

Operations Management Report short lead time but low quantity outputs. And the price is published daily. The commercial department has authority and responsibility to make decision on order (which companies are suppliers for each period for reorder point and order detail)

IX.

MATERIAL REQUIREMENT PLANNING AND ERP

At the present time, East Asian doesn’t have MRP or ERP computer system. In short term, East Asia will use MRP software of Lac Viet Co., Ltd for management system

X.

SHORT-TERM SCHEDULING

As we know the important role of scheduling in an organization as the competitive advantage of this institution from faster movement of goods through a facility, faster deliveries, and reliable deliveries. In East Asia Company, scheduling also play an important role like that. For the fixed scheduling with auto-machines, scheduling is assigned correspondingly from each worker group to each task with a specific machine in continuous production. Basing on the demand or requirement form the market, the manger can give out the requirement of output for each period, so that, for each period the scheduling should be changed, and worker is ranged in the most suitable position of time and task. It is very effective because it does not make worker bored, they are more willing to work in different tasks and different time.

XI.

FORECASTING

Base on the development of Vietnamese economic (GDP, population), the department of marketing will forecast the future plan on October and November for the next year. As the development of the company, East Asia co., Ltd will invest on new equipment, maintenance-process … with high quality, and update the management program continuously

D.

CONCLUSION

East Asia co., Ltd is one of the 500 largest private companies in Viet Nam, qualified as ISO 9001:2000 about product. The current volume of products has not met the large demand for steel in Viet Nam. So, with the proud of customer satisfaction about its high quality products, East Asia Co., Ltd will enlarge production as well as the size of company more and more in the future.
