5.2 Recommended solutions
CHAPTER V
5.2.1 Incentive system development
From Table 5.1, it can be concluded that incentive system can help to company to improve product quality, and also incentive system is one of continuous improvement tools which enhance company’s capabilities to continue satisfying customers as well as making profits. Prior to developing incentive system, the company should find the method to assess employees’ quality performance, and then develop incentive system that pay extra earnings to employees based on their performances.
Moreover, incentive system can enhance continuous motivation of employees for the reason that they will realize that their good performances will not be neglected, and that keeps employees to perform well. As stated in Chapter 4, incentive system is useful for small companies that more complex or sophisticated systems have not been developing, and since products of Aqua Vis Co., Ltd. are mostly hand-made, a continuous improvement tool must enhance employees’ morale in the early stage in order to continuously increase employees’ focuses on quality improvement until the company is able to develop more sophisticated system in the future. The demonstration of incentive system is shown in Appendix C.
5.2.2 Statistical Process Control (SPC) development
As stated earlier in Chapter IV, SPC can help the company to recognize how much defect occurred in each process, so the company can solve defect problem at the right spot. Since the company has not been developing SPC, SPC should be one among top priorities to be developed and implemented in the near future. Example of SPC is shown in Appendix D
5.2.3 Supplier Evaluation
This research found out that quality of suppliers has direct impact on product quality because without good quality of raw materials, good product quality is unachievable. In order to make sure that the company can acquire good raw material quality, the company must be able to select only suppliers which can provide high quality of raw materials, and one method that can ensure that the company has good quality of suppliers is supplier evaluation. According to the interviews, all respondents recommended that the company should evaluate suppliers based on quality of raw
materials and ability to deliver on-time. Therefore, the example of supplier evaluation is shown in Appendix E.
5.2.4 Customer Involvement
According to table 5.1, the impact of customer involvement towards product quality is inconclusive; however, to ensure product quality without reduce employees’
morale, the company should limit customer involvement so that customers cannot interfere with manufacturing processes which will create frustration among employees, and this issue can decimate quality of the products. Consequently, the role of customers should be limited to informants who provide the company designs and specifications, and the company has responsibility to make sure that the products are conformed to designs and specifications.
5.2.5 Training
Since quality is the most important aspect for profitability of the company, employees’ skills and capabilities to ensure product quality, especially for handmade products. So, it is very important for the company to enhance employees’ skills and capabilities by send those employee to training programs. The company has a plan to send CNC specialist to training course so that this staff will gain more knowledge about how to operate the machine, and new techniques to produce better product quality. For in house training, this will focus more on temporary staffs in which permanent staffs will teach them how to use the appropriate equipment, and also production details in each process to ensure that temporary staffs will be able to substitute permanent staffs in case of emergency without affect product quality. Training will be involved with production training in each process, quality check training, and CNC (CAD & CAM) training. CNC training will be the only training that the company has to send the staff to train outside the company because the company does not have competency in this aspect.
5.2.6 Preventive maintenance schedule development
From Table 5.1, preventive maintenance is one of the factors that can improve product quality because without equipment breakdown, the company will not have interruption in manufacturing processes so that the company can maintain initial time constrain. As a result, production staffs do not have to rush the production that caused by equipment breakdown, then they can focus more on quality; however, the company has not been developing maintenance schedule for both daily and yearly. The easiest method for daily maintenance is using checklists of important components of each machine, these checklist will be used to check readiness of each machine before production starts in each day. By using this method, production staffs can recognize abnormality or damage on the machine so that they can report to top management. Then the top management can contact service team to repair as soon as possible. For semi- annual maintenance, the company will contact machine’s manufacturer of CNC machine to thoroughly check overall condition of CNC machine to ensure that this particular machine works properly. CNC service team will visit the factory on June 31 and the end of the year. Therefore, the company has to develop maintenance schedule to ensure good condition of the equipment, and also the company should have machine inspection twice a year by machine manufacturers in order to recognize which part of the machine requires repair or replacement as suggested by interview respondents.
Preventive maintenance schedule and checklist are shown in Appendix F.
