Methods of Measuring Design Quality

in that location ar several methods by which companies measure the endeavor look of products, attends and processes. The companies select the methods in accordance of rights to their goals. Accordingly the methods for bill origination feature may be generic desire the reus office of practice or particularised same the size dimensions of gesticulate ashes. Whatever be the rhythmic pattern use, thither is a trend towards victimization a combination of weights and judge scales for objectively measuring devise prime(prenominal). whiz approach to measuring form woodland is examining the extent to which the different separate or the sub placements of the name depend on one another. From this stand buck those pictures that be inflexible, and return a high degree of interdependence cannot substantially be changed. When a change is introduced it has a surging effect and it becomes unrealistic to guess the cost of such a change. These designs create a posture whe re the managers very r atomic number 18ly allow changes.Another way of assessing design quality is to test its reusability. If the needed parts of the design are highly leech want on other details, design is highly interdependent. In such a situation is cardinal to see if the design can be use in a different situation or a combination. For ideal, if thither is an embossing unit designed as a part of a formative stretching line. Can the embossing unit be separated from the line and utilise in a different plastic stretching line? go on with the example, can the plastic extruder be separated from the line and used as a part of another plastic strapping line?Finally, is there a tendency of the system to break in several places when a one change is made to the system? If the design is brittle past there are problems in areas that have no direct confederation with the changed area (Akao, Yoji 2004). In the plastic stretching line if the embossing unit is withdraw there is a probl em in the cooling unit. Such brittleness reduces the reliability of the design and creates maintenance problems. The production personnel cannot rely on the production specifications.Another approach to measuring the quality of design is to judge the specifications of the designs in terms of the realization of its objectives. The cost of implementing the design and the ease with which the braid can be produced are evaluated. A strong correlation is ordinarily present between the design and the specifications and the ratio can be used as a reliable measure of design quality (Park, birdcall H1996).Another measure of design quality is to measure design performance(Belavendram, N 1995). In this case the design quality evaluates a number of factors like the craftsmanship, the cost of design, the cost of production, and even the return on investment of the design process. In case the design is made by an internal team there is even a comparison of the performance of the design with th e evaluate performance from external designers. amount the design quality has as tot uped rude(a) importance with how designs are being managed to increase value of the organization to its customers. instead of tangible end products, there are companies that evaluate the designs of business models and modify its designs to ensure that every interaction with a customer is dependable and persuasive. bearing quality is in any case measured from the point of view of the substance abuser. The design is anticipate to make the process clear to the user. Moreover, the design should make the behavior of the organization, system or the process dependable to the user, Further the design should be such that the process or the system should provide feedback. In case of interaction with the customer, the feedback should be both visual and audio. The message however, should be clear.The design of a process or a system should be such that the user should effectively be able to trace the path of action (Hoyle, David 2005). There should be a close correspondence between the specifications that have been habituated to the user and the manner in which the system works. Finally, the design should allow for measures of control.Measuring design quality is often a task of applying ordinary principles of intent. The general principles of designing include questions like is the design trouble-free? An uncomplicated and unsophisticated design is preferred. Also is the design is long lasting? An adaptable design is desirable and so is a time little design. The design should appeal to the future(a) generation.A computable design solves the moot problem (Hayes, Bob1998). A good design gives a a couple of(prenominal) elements to the users that can be combined by the users themselves. A lot of work goes into a high quality design and this is reflected in the design itself. One of the poetic rhythm widely used in measuring design quality is the use of symmetry. Further, the fin e tuning that has been through with(p) to the design to improve its quality and performance. tone of voice design can be replicated and is different from the norm. Finally, good design is done in large pieces.From the scene of production management it is important to remember that the design quality is important in cause control system. In this context the quality of design embraces the natural selection of the motor drive electronics, positioning mechanism and interrogative controller.. mark quality emerges from the planning that goes into the development of the system. Designing quality entails full exposition and understanding of the process. Meticulous details go into this designing stage like the precision of the motion, the travel length of every axis and the number of axis.A good quality design specifies if the positioning is rotary, linear or a combination of stages (Card, David N & Glass. R 1990). The quality of design is also evaluated by the manner in which it inc orporates the stage as an integral part of the big system. The ability of the stage to meet its specifications is also an important consideration in measuring design quality. The design also encompasses the way in which the system is mounted on a flat surface to avoid distortions. The quality of design is also judged from the way in which the lifetime requirements of the system are incorporated into the stage specifications.If the requirements change then the system may have to be removed to a different position during its lifetime. Good quality design takes into consideration the size and the environmental consequences of the system. Both horizontal and steep size constraints need to be considered. Factors like the choice of drive type, selection of motor and the mechanical and electrical aspects of the system motions are important factors in appraising the design quality.In the context of customer dish up, measuring design quality means evaluating parameters that go into a bett er provision of service to the customers. To deliver consistently superior service requires a high train of design quality. The design must include processes, people and the technology. Only if the design is of high quality will the company get increased gross sales from customers that have experienced superior service. The design often extends to aspects of information technology.The designing of products and service responses based on data often are full of life in attracting and retaining customers. The quality of design reflects on the services provided like introduce the choices of individual customers, payment methods, patterns of buying, support websites and live chats with technical staff. To be prospering the design must consider factors like support technology, culture of the organization, motivator system, training and recruitment of customer support staff.In most situations like a production setting or a customer service system, there are some metrics that are sele cted for measuring the design quality. Usually, these metrics are based on the objective of the organization and are discussed with the designer before the design commences (Wood, Jane & Silver, Denise 1989). For example, the company that wants to design a motion control system will discuss with its production engineers specifications that are needed for the motion control system and agree on a few metrics that will be used to measure the design quality.For example it may be the positioning of the linear rotary, the adaptability of the system, the size of the system, the stopping ability of the drive and precision of the description of the system. Each of these metrics for measuring design quality should be presumptuousness a weight so that the sum of the weighs adds up to 1. For example, the stopping ability of the drive may be given a weight of 0.3 and the precision of the description of the system may be given a weigh of 0.1 and so on. In practice these weights are decided join tly by the management and the designer.A document for measuring design quality typically has a rating scale of quin attached to each metric. After the design is completed a rating is given to each metric. The rating may site from 1 to 5, where 1 is the lowest rating and 5 is the highest rating. Each rating is multiplied with the several(prenominal) rating. For example the stopping ability of the drive may get a rating of 3, this figure is multiplied by its weight of 0.3 and we get a story of 0.9. The scores for each metric is added and a composite score is metric. As the weights add up to 1, the composite score ranges from 1 to 5, with 1 being the lowest design quality and 5 the highest possible quality measure. The actual composite measure for design quality will range between 1 and 5.To sum, there is a wide range of metrics used for measuring design quality. Some are generic metrics like the flexibility of the design, the adaptability or its brittleness. Others are metrics re lated to specific situations like the metrics for measuring the design quality of a motion system. Design quality of customer support systems or HRM recruitments systems are also measured with respect to the goals of the design. These metrics are then rated according a previously decided standard, weighted and a composite score is calculated to give a comprehensive measure of design quality.ReferencesAkao, Yoji (2004), Quality act Deployment Integrating Customer Requirements into Product Design, Productivity PressBelavendram, N (1995) Quality by Design, Prentice HallCard, David N & Glass.
