Abstract Laboratory of Machine Design at the University of Oulu has modelled the production information for a gear transmission unit in co-operation with a Finnish gear manufacturer, Santasalo Ltd. The basic idea was to integrate computer aided design into modern FMS-based production activities. The main goal in this project is to capture the whole gear box development process from customer requirements to manufacturable assembly and detail information in OOA models.

Establishing product requirements for the customer is usually the first step in the product development process. Indeed, identifying and fulfilling customer requirements is the key for successful product development. However, satisfying all the customer requirements is not always possible. Therefore, the best design is the design that fulfils a set of the most important customer requirements. Due to this, design process needs to be agile and iterative. Design and its requirements need to be effectively iterated.

The concept of reuse is applied in one of the agile development methodologies called the scrum. Sprint is a single functionality and the result at the end of the sprint functionality is derived as the shippable or bugs. This paper makes an attempt to use the concept of reuse in the agile software development to meet the dynamic change of customer requirements in banks. A banking project is created using both waterfall model and scrum model, and the knowledge gained is stored in the ontology-based repository for the first time. Again, the same project is created for different vendors using the ontology-based repository. The result shows that maximum sprint is reused and all the knowledge gained is stored in the form of ontology. This ontology helps identify the shippable component of each sprint which is a small executable functionality. This leads to less cost and time to deliver the product. The main aim is to increase the availability of the reusable artifacts, which lead to increase the reusability of the developer. The experimental results show improvements in the performance of retrieving the components for the software development.

Quality function deployment (QFD) is one of the most popular tools used in the product development process. It relates customer requirements to product requirements and enables engineers to determine which product requirement is more important than the others in satisfying customers. Some of the benefits of QFD are cost reduction, fewer design changes at the start of production, and improved communication among engineers. QFD applications use various approaches (i.e., worth calculation schemes and rating scales) to calculate the worth of requirements. The purpose of this paper is to study the change in the relative worth (normalized worth) of product requirements yielded by different rating scales and calculation schemes. We studied empirical and simulation-generated QFD matrices to determine how calculation schemes and rating scales influence the relative worth of requirements. Two representative scales and two calculation schemes are used to find the most and least sensitive cases, and the influence of the number of rows and columns in the relative worth of requirements. From the results, we identified the least sensitive and most sensitive combination of calculation scheme and rating scale. We also learned that QFD matrices become less sensitive to changes in rating scale and calculation scheme as the number of columns increases.

Fehler bei der Inbetriebnahme von Maschinen und Anlagen sind kostspielig und zeitintensiv. Dabei steigen die Kosten mit dem Voranschreiten des Entwicklungsprozesses stark an. Um Missverständnisse oder Planungsfehler zu minimieren, bevor diese hohe Kosten verursachen, wird ein intelligentes Assistenzsystem beschrieben, das die Vorstellungen, Ziele und Mittel des Kunden auf einfache Weise erfasst und auftretende Probleme oder Unklarheiten reaktiv korrigiert. Der Maschinen- und Anlagenhersteller profitiert dabei von einer automatisch erstellten, einheitlichen Dokumentation der Kundenanforderungen.   Errors during commissioning of machines and plants are costly and time intensive. The costs grow higher with every step of the development process. To minimize misunderstandings and planning errors during the requirements phase, an intelligent assistance system is being introduced which acquires the ideas, goals and resources of a customer in a simple manner and reactively corrects arising problems or ambiguities. The machine and plant manufacturer profits from the uniform documentation of customer requirements.

Shape grammars provide the means to represent the physical embodiment of a class of products in a set of generative rules. Once developed, the shape grammar can be used to generate new forms through automated synthesis or interaction by one or more designers. Creating the shape rules has been most often performed after the design process by examining existing designs. Furthermore, the approach to create a set of rules from an existing set of products was usually an ad hoc process of generalizing form, identifying feature options, and classifying logical subdivisions of the complete product geometry. This paper proposes a more explicit method of shape grammar creation, that is, aligned with well-known design methodologies in order to enable the creation of a shape grammar during the new product development process. The established methodology for function first design and design exploration provides many of the requisite steps for creating a shape grammar, connecting customer requirements and constraints to product form and provides a skeleton onto which a rule creation approach is mapped. An example is included in which the proposed methodology is used to create a shape grammar that represents the internal components of a bladeless slurry pump in order to support design exploration driven by simulation and experimentation.

The search for value generation has recently increased in the construction industryin the past decades. However,somedifficulties in capturing end-customer requirements, controlling the flow of information, and optimizing project development phases prevent a product development process from receiving greater value aggregation. The present research aims topropose a set ofstandards for the management of these steps.In this way, a case study wasdeveloped in a small architecture office inArapongas -PR, through the mapping of the project process. After a survey of the positive actions andlags of the current managementthe processesof the microenterprise weremodeledthrough an organizational software andthe information obtained was then contrasted by means oftheoretical references. This study enableda final set of guidelines to reduce management errors and sequence of activities to a minimum.

Abstract Purpose: The objective of successful companies is the integration of customer requirements in the development process of a new product. Therefore, the Quality Function Deployment method has proven useful several times. The customer requirements often contain contradictions, which are mostly solved by compromises. The aim should be to integrate all customers’ demands and wishes into future products. Methodology: The theory of inventive problem solving can be applied to eliminate compromises in the product development. The method’s different tools enable a goal-oriented and systematic conflict resolution and may help to uncover trends. This paper displays an approach where individual tools of TRIZ are integrated into the Quality Function Deployment. Results: The result of this work is the presentation of the resulting benefits from combining the two methods. For this reason, individual tools of TRIZ are used in different points of the QFD process. The paper shows examples of starting points. Value of paper: In the context of this paper, the benefits from the interaction of QFD and TRIZ are presented. These are particularly evident in the initial phase of project implementation. In this phase the goal of the QFD process is to succeed in translating the voice of the customer for the company and then integrating it into the product development.

Abstract The method of “Key Characteristics” (KCs) is gaining popularity in many US companies as a way to focus the organization on important product features that have a significant impact on product and customer requirements. (Lee et al., 1995; Lee and Thornton, 1996) Research was undertaken at several major US corporations to understand the current and best-practice use of key characteristics. The methods in use were found to be lacking in formality and ease of application. Our observations and subsequent research has resulted in the enhanced key characteristic definitions, categorization, prioritization, and identification methodology presented in this paper. Two case studies using an automotive and an aircraft product are used to illustrate the key characteristic identification method. A high risk key characteristic (referred to as “StatKCs” in this paper) identification technique was also developed that establishes a quantitative relationship between customer requirements and manufacturing costs. The methods presented in this paper can be used to support efficient and effective strategic and operational decisions during the product realization process.
