Traditional Design

Small and medium-sized enterprises face the challenges that they do not have enough employees and related resources to produce high-quality products with limited budget and time. The emergence of crowdsourcing provides an opportunity for them to improve their products by leveraging the wisdom of a large community of crowds, including their potential customers. With this new opportunity, product design could be conducted partially in a traditional design environment (in-house design) and partially in a crowdsourcing environment. This article focuses on product design stages to investigate what key factors affect product design quality and how it can be controlled and assured. First, we define the concept of product design quality and then identify its attributes and sub-attributes. Second, we separately survey key factors affecting product design quality in traditional and crowdsourcing-based design environments, quality control approaches/theories and quality assurance policies in traditional design environment. Third, a comparison of product design quality issues between the traditional and crowdsourcing-based design environments is progressed focusing on various aspects influencing product design activity quality. Finally, we discuss product design quality control approaches and quality assurance policies, quality control challenges and corresponding solutions in crowdsourcing-based design environment.

Background This study aims to understand the key factors influencing guardians’ decisions when purchasing spectacles for their children in semi-urban and urban areas of Cross River State, Nigeria, where a spectacle cross-subsidisation scheme will be implemented. Methods This cross-sectional study was conducted among all consecutive guardians visiting the Calabar (urban), Ugep, Ikom and Ogoja (semi-urban) public eye clinics in Cross River State, southern Nigeria, from August 1 to October 31 2019, and whose children had significant refractive errors (myopia ≤-0.50D, hyperopia ≥1.50D, astigmatism >0.75D) and received spectacles. Guardians were interviewed using a questionnaire which included i) close-ended questions on reasons guardians choose to purchase spectacles for their children in eye clinics, ii) guardians’ perceptions of the quality and design of children’s current spectacle, iii) factors most heavily influencing their choice of spectacles for children, and iv) open-ended questions to seek guardians’ suggestions on how to improve the current spectacle range. Results All 137 eligible guardians (67.2% women [n = 92]) who visited the selected eye clinics participated in the study (response rate = 100%), with 109 (79.6%) from semi-urban and 28 (20.4%) attending urban clinics. Guardians from both urban and semi-urban clinics prioritised frame design, quality, and material as the main factors affecting their decision when purchasing spectacles for their children. Female guardians and those with higher incomes were both 1.5 times more likely to emphasise frame quality when describing selection criteria for purchasing spectacles for their children than male guardians (p = 0.01) or guardians earning less (p = 0.03). Conclusion Design, material, and frame quality are key factors influencing guardians when purchasing spectacles for their children in these setting and female guardians or those with higher income prioritise frame quality. This study could guide the planning and implementation of a novel cross-subsidisation scheme in Cross River State.

Cryopreservation in aquatic species in general has been constrained to research activities for more than 60 years. Although the need for application and commercialisation pathways has become clear, the lack of comprehensive quality assurance and quality control programs has impeded the progress of the field, delaying the establishment of germplasm repositories and commercial-scale applications. In this review we focus on the opportunities for standardisation in the practices involved in the four main stages of the cryopreservation process: (1) source, housing and conditioning of fish; (2) sample collection and preparation; (3) freezing and cryogenic storage of samples; and (4) egg collection and use of thawed sperm samples. In addition, we introduce some key factors that would assist the transition to commercial-scale, high-throughput application.

The A new design method of the products named “Systematize Design” has been advanced in this paper. From the view of the point of the system engineering, the planning of product design makes the product design qualities improve to a great extent. Besides the understanding of the client requirements, the design planning of products, the so-called 7D’s: Design ideas, Design environments, Design objective, Design process, Design contents, Design methods and the Design quality evaluation, should be considered completely and planned systematically. Based on the previous work, the product design should be conducted according to the systematic design method. The paper makes a detailed expatiation of the systematic design method, viz. 1+3+X design method, in which 1 represents the optimal design for product functions, 3 means the design method synthesizing the dynamic optimization, intelligent optimization and visualized optimization combined organically, and X is the design method for the special requirements of the products.

Clearly it made the design quality concretized into the product function and three performances. Expounded the concept of product design quality control, analyzed the influencing factors of product design quality, formed the design idea of quality control; aiming at the existing problems of traditional product design, established design quality control preliminary model by applying systematic design theory.

With the emergence of information systems reliability and quality assurance and its perceived revenue generation in the billions of dollars, the accounting profession has developed a keen interest in improving the understanding of the underlying factors affecting information quality. This paper expands the Havelka et al. (1999) study, which explored the key quality factors impacting the information requirements definition stage of the systems development process. The extensions explored within the current paper focus on the relationship between users perceptions toward information systems and key quality factors for systems design. In particular, user involvement and user satisfaction are examined for their potential impact on the weightings of quality factors. The results indicate that users perceptions toward information systems do influence their perceptions of the importance of the key quality factors for systems design. This result may allow practitioners to tailor a project management strategy for IS development based on targeted users current perceptions of information systems.

Set Up

Design and R&D (Research and Development) of products play an important role in development and competitiveness of enterprise. How to do the works better? We think that most advanced product design methodology should be used on design, research and development of products. So-called most advanced product design methodology is that based on “the Scientific Outlook on Development” that we set up recent years. New developments of product design methodology include: At first it has been classified that more than seventy theories and methods proposed by domestic and overseas scholars in recent 100 years; QCTES was instead of IQCTES including six requirements of product design; traditional design stages were replaced with four new stages including investigation, planning, implement and inspection; green design was replaced with harmonious design; traditional design method was replaced with deep-layer design method; concept and connotation of product top-layer design were proposed; more detailed contents of product systematic design were advanced; formulas of complete system and product design quality, and connection equation between design objective, design content and design method were submitted. We got good effects to apply above product design methodology on many product designs recent years.
