Many modern approaches to engineering design seek to optimize design in order to maximize the value of the system to its customers. These approaches rely on the formulation of a system utility function as a measure of system worth. It is shown here that, under certain circumstances, however, such a measure cannot exist. It is then indicated that these circumstances comprise the rule rather than the exception. Finally it is shown that pursuing the objective of design optimization as defined by the customers via contemporary approaches can lead the designer to highly inappropriate and undesirable designs. As a consequence of this, it becomes apparent that the methods of Total Quality Management (TQM) and Quality Function Deployment (QFD) can lead to highly erroneous results.

Abstract The Mechanical Engineering Design curriculum at Santa Clara University has been reviewed using the principles of Total Quality Management. The review has led to a clear mission statement and the inclusion of an explicit component of Critical Thinking in our curriculum. We have begun to develop the educational process that will enable us to accomplish this mission.

AbstractThe performance of suppliers both directly and indirectly determines several critical points for the company such as: product prices, product availability in the market, and product quality. It is very important for companies to monitor and improve the quality of raw materials obtained from suppliers, because this will determine the performance of the company, especially on the quality of products produced. The quality monitoring system implemented in the company must be responsive and consider every critical aspect of the non-conformity that occurs, not only using the Supplier Correction Action Request (SCAR) form or the Vendor Corrective Action Request (VCAR) form or the Supplier Corrective and Preventive Action Request (SCPAR) form for all types of non-conformity found. In this study, samples were taken at 3 different companies in order to obtain valid data to analyze and evaluate the existing quality monitoring system to get a new quality monitoring system that more responsive to avoid repeated findings occur. The research method was conducted by classifying non conformity types based on the level of criticism using the Total Quality Management (TQM) approach, fishbone diagrams, Failure Mode and Effect Analysis (FMEA), and Quality Function Deployment (QFD) so that the quality monitoring system produced is more accurate, effective and efficient in handling raw material non-conformities that occur. AbstrakKinerja pemasok baik secara langsung maupun tidak langsung ikut menentukan beberapa point kritikal bagi perusahaan seperti: harga produk, ketersediaan produk di pasar, dan kualitas produk. Sangat penting bagi perusahaan untuk memonitor dan meningkatkan kualitas bahan baku yang diperoleh dari pemasok, karena hal ini akan menentukan performa bagi perusahaan terutama terhadap kualitas produk yang dihasilkan. Sistem monitoring kualitas yang diterapkan di perusahaan harus responsif dan mempertimbangkan setiap aspek kritikal ketidaksesuaian yang terjadi, tidak bisa hanya menggunakan Supplier Correction Action Request (SCAR) form atau Vendor Corrective Action Request (VCAR) form atau Supplier Corrective and Preventive Action Request (SCPAR) form untuk semua tipe non conformity atau ketidaksesuaian yang ditemukan. Dalam penelitian ini, dilakukan pengambilan sampel  di 3 perusahaan yang berbeda dengan tujuan agar didapatkan data valid guna menganalisis mengenai sistem monitoring kualitas yang telah ada saat ini dan mengevaluasi untuk mendapatkan sistem monitoring kualitas baru yang lebih responsif sehingga tidak terjadi lagi temuan berulang. Metode penelitian dilakukan dengan mengklasifikasikan tipe non conformity berdasarkan tingkat kritikalnya menggunakan pendekatan Total Quality Management (TQM), penggunaan fishbone diagram, Failure Mode and Effect Analysis (FMEA), dan Quality Function Deployment (QFD) sehingga sistem monitoring kualitas yang dihasilkan lebih akurat, efektif dan efisien dalam penanganan ketidaksesuaian bahan baku yang terjadi.

<p>Human power’s quality plays the key role in the growth and development of societies where the quality of human powers can be enriched with the high quality education provided by the higher education institutions. The higher education institutions are hereby an important sector of any society since it defines the overall quality of human lives. This research will investigate the application of Total Quality Management (TQM) tools at the higher education institutions; specifically at ALHOSN University. In this study five tools were implemented at ALHOSN University’s engineering college including: Quality Function Deployment, Affinity Diagrams, Tree Diagrams, Pareto Charts, and Fishbone Diagrams. The research will reveal that the implementation of TQM tools has a great benefit for higher education institutions where they have uncovered many area of potential improvement as well as the main causes of some of the problems the Faculty of Engineering is facing. Also, it will show that the implementation of TQM tools on higher education institution systems will enhance the performance of such institutions.</p>
