Estimating the final priority ratings of engineering characteristics in mature-period product improvement by MDBA and AHP

Quality function deployment (QFD) has been widely used to translate customer requirements (CRs) into engineering characteristics (ECs) in product improvement. Product planning house of quality (PPHOQ) is of fundamental and strategic importance in the QFD system. In the construction process of the PPHOQ of mature-period (MP) product, correctly estimating the final priority ratings of ECs is essential, because it will largely affect the target value of ECs for improvement. To exploit competitive information of MP products, this paper develops a comprehensive and systematic methodology to rate the final priority of ECs for MP product improvement. The proposed method is on the basis of maximal deviation based approach (MDBA) for dealing with the corporations' performance estimations of ECs, and it integrates AHP and scale method for analyzing the priority rating of achieving the improvement goal of performance evaluation (IGPE) of each EC. Finally, a case study is provided to illustrate the effectiveness of the proposed method.     

Economies and Diseconomies: Estimating Electricity Cost Functions

This paper presents estimates of the variable cost function ofelectricity generation. The cost function is estimated using a two dimensional definition of capacity utilization. Because electricity cannot be conveniently stored, generation facilities follow the load across demand cycles. Capacity utilization can be captured empirically in two ways. One is generation relative to capacity when a unit is connected to the system; the other is thepercent of time the unit is disconnected. The estimated cost function shows that both dimensions affect average cost, which generally declines as capacity utilization increases.     

Planning perceptions and planning results

The need for planning in business organizations operating in today's complex environment is widely accepted. Implied is an assumption that planning improves performance. However, the empirical evidence for such a claim is thin. Since planning is an integral part of strategy formulation, the facts to confirm or refute an assumed connection between planning and performance invite attention. Our research focuses on new data from 61 companies which test this linkage and, in addition, reviews the conclusions of prior empirical studies.     

From Empowerment Dynamics to Team Adaptability: Exploring and Conceptualizing the Continuous Agile Team Innovation Process

To foster their innovation teams’ adaptability, organizations are increasingly relying on agile teams. While research on the adoption of agile methods and practices has grown tremendously in the past decade, little is currently known about the human side of agile teams and how it contributes toward the emergence of adaptability. While the Agile Manifesto states that individuals and interactions are more important for agile product development than tools and processes, research on how these interactions unfold is still in its infancy. To shed light on the human side of adaptability, 44 semi-structured, in-depth interviews were conducted with team members and leaders from various teams at three organizations (i.e., two German and one multinational European firm). The inductive analysis identified empowerment as a focal human factor for adaptability emergence. A model of the continuous agile team innovation process is developed and uncovers the importance of dynamic empowerment states and their temporary equilibria for team adaptability. The underlying findings demonstrate that empowerment is not a static state, but rather emerges through the interactions between various actors. Specifically, the team and its leader engage in both empowerment-enhancing and empowerment-reducing activities. These activities are further influenced by the agile team’s immediate context: Two-fold customer influences, that is, supporting and hindering empowerment interactions, and the organizational environment, that is, undergoing an agile transformation and supportive top management behaviors, play an important role in affecting the empowerment dynamics that result in team adaptability. As such, this study contributes to the innovation and management literatures by revealing the dynamic role of the empowerment and adaptability constructs for agile innovation processes and the importance of various actors and the organizational environment for fostering adaptability. Practical insights are offered to management, teams, and team members on how to create conditions for empowerment dynamics and consequently adaptability to unfold.

Estimating and comparing learning curves in three Asian economies

This paper consists of two parts. In the first, a method is suggested to isolate the effects of scale economies on learning phenomena by integrating the conventionally specified learning curve with the production function in neoclassical economics. The problem of establishing the variable for measuring experience is dealt with in the estimation procedure. Using this method we estimated the learning curves of 20 industries in the manufacturing sector in Singapore using data taken from 1961 to 1991. More modern industries like electronics, precision instruments and pharmaceutics have steeper learning curves than older industries. Among traditional industries, the food and beverage industry has a greater learning potential than others. In the second part of the paper, the learning curves for 11 common industries in South Korea, Japan and Singapore were estimated and compared. The Japanese industries are found to have steeper learning curves compared to those in Singapore and South Korea.The authors are from the Department of Business Policy, Faculty of Business Administration, National University of Singapore. The authors would like to thank Ms Tan Mui Lee for her assistance in preparing the time series data used for this study.     

Planning system characteristics and planning effectiveness

The nature of the multivariate relationship between six characteristics of planning systems and three different conceptualizations of planning effectiveness is examined using canonical correlation analysis. The analysis indicates that the organizational context of planning—captured here by two key characteristics—resistance to planning and resources provided for planning—is the dominant impact on planning system effectiveness, broadly construed. While individual design elements of the planning system such as use of techniques and external orientation do influence effectiveness, the contextual dimensions appear to be overriding. Implications for further research on planning systems and directions for future extensions of this study are discussed.

Estimating store choices with endogenous shopping bundles and price uncertainty

We develop a structural model of retail store choices for which household shopping plans and price beliefs are endogenously determined. In our model individual households make their store choices based on their expected basket costs, which are determined by their shopping plans and price beliefs. Previous studies use realized purchases as a proxy for unobserved shopping lists and also assume homogenous price expectation across all households over the entire sample period. Our approach improves the measures of expected basket costs by estimating intended shopping lists of households using a duration model and also by constructing household-, time-, store-, and goods-specific price expectations. In our empirical application using a scanner data set, we find that the store choices become significantly more elastic to prices when the correction is applied.     

Estimating the demand for ADSL and ISDN services in Greece

The aim of this paper is to investigate the demand for broadband services in Greece and to estimate the price elasticity of the demand for ADSL and ISDN services as well as the cross-price elasticity between the two services. The empirical analysis uses the 384 kbps connections since for the period examined, over 85% of the total ADSL customers in Greece are connected at this bandwidth. The empirical analysis is based on an ad-hoc specification of the demand equation, with no reference to the utility maximization problem of the representative consumer. The results of the analysis show that both demands are inelastic. In addition, cross-price elasticity for ADSL is negative, indicating that ISDN is a complement to ADSL, whereas the demand for ISDN is almost neutral to ADSL.     

Planning and uncertainty in new product development

The domain of New Product Development (NPD) is subject to considerable uncertainties. Aside from market‐related sources of uncertainty, the degree of innovativeness of the underlying product concept is a significant source of uncertainty, as unclear goals and specifications like, e.g. product specifications may lead to substantial delays in the project. However, companies are required to manage the innovation process as efficiently as possible. The resulting conflicting demands often leave companies struggling to achieve both efficiency as well as flexibility due to their often opposing implications for organizing and managing NPD projects. In this context, planning plays a central role; however, its usefulness for NPD project success is perceived quite differently. While there are reports about a positive influence of initial planning on various success measures, others have questioned the effectiveness of elaborated initial planning and contend that the ability to rapidly react to changes later in the process and to improvise may lead to success in NPD. This study aims at achieving a better understanding of planning in NPD by investigating a sample of 475 Research & Development projects in Japanese electrical and mechanical engineering companies. Regression analysis is used to shed more light on the interplay of planning intensity, changes, and the degree of technological newness of the NPD project and their influence on project success. Our results indicate planning to be of value for different types of innovation projects. Furthermore, the influences of the variables in question vary with the success measures that are taken into account, indicating that a more detailed and contingent understanding of planning in NPD needs to be developed.
