Abstract

Purpose

The purpose of this paper is to propose the use of a user-centric service map to facilitate the visual exploration and monitoring of user context information for proactive market analysis.

Design/methodology/approach

The paper supports a context-based market analysis by developing a user-centric service map which comprehensively visualizes a variety of contexts, users, and services. Empirical data were gathered from service descriptions and reviews of 100 mobile application services in the Apple App Store’s lifestyle and healthcare and fitness categories.

Findings

The user-centric service map supports the analysis of the context information from using various mobile app services, and can therefore be effectively applied for market-segment analysis and user-value analysis.

Practical implications

The user-centric service map involves implications in terms of multi-disciplinary proactive market orientation and data-driven strategy development, allowing firms to respond to changing market conditions in the mobile business promptly and even preemptively.

Originality/value

The initiative uncovering of latent needs through examining context of use have been an important focus of prior work, but little attempt has been presented in the way of frameworks for converting abundant context data into strategic information. The paper provides new methods and procedures to establish and interpret service maps using flexible visual features.

Abstract

Purpose

The purpose of this paper is to show that existing project portfolio management methods have failed to take firms' long‐term strategies into account. To overcome this limitation, it is proposed to suggest technology road‐maps (TRMs) as a tool to assist with project selection and planning.

Design/methodology/approach

Based on bibliographic and qualitative analysis, the paper develops a systematic process of building TRMs for project portfolio management. The proposed process was applied to the project selection and planning process of a Korean government R&D program.

Findings

The paper finds that the suggested process can support strategic planning by assuring that an organization is implementing the right projects at the right time. During this process, the selection of experts, the flexibility of the process, the periodical updating of the TRM, and TRM standardization are regarded as critical issues for high‐quality technology road‐mapping.

Research limitations/implications

The approach in the paper does not deal with the cost and profitability aspects of a project as part of its evaluation, nor does it consider complex relations between technologies in different projects.

Practical implications

The findings in the paper are expected to be helpful in establishing R&D strategy and setting priorities among projects, and in fostering coordination in project implementation.

Originality/value

This paper is one of the earliest attempts to systemize TRM methods specifically for project portfolio management, and is expected to make it easier for companies to adopt and apply TRMs effectively.

Abstract

Purpose

The purpose of the paper is to distinguish features of m‐commerce from those of e‐commerce and identify factors to influence customer satisfaction (m‐satisfaction) and loyalty (m‐loyalty) in m‐commerce by empirically‐based case study.

Design/methodology/approach

First, based on previous literature, the paper builds sets of customer satisfaction factors for both e‐commerce and m‐commerce. Second, features of m‐commerce are identified by comparing it with current e‐commerce through decision tree (DT). Third, with the derived factors from DT, significant factors and relationships among the factors, m‐satisfaction and m‐loyalty are examined by m‐satisfaction model employing structural equation model.

Findings

The paper finds that m‐commerce is partially similar in factors like “transaction process” and “customization” which lead customer satisfaction after connecting an m‐commerce site, but it has unique aspects of “content reliability”, “availability”, and “perceived price level of mobile Internet (m‐Internet)” which build customer's intention to the m‐commerce site. Through the m‐satisfaction model, “content reliability”, and “transaction process” are proven to be significantly influential factors to m‐satisfaction and m‐loyalty.

Research implications/limitations

The paper can be a meaningful step to provide empirical analysis and evaluation based on questionnaire survey targeting actual users. The research is based on a case study on digital music transaction, which is indicative, rather than general.

Practical implications

The paper meets the needs to focus on customer under the fiercer competition in Korean m‐commerce market. It can guide those who want to initiate, move or broaden their business to m‐commerce from e‐commerce.

Originality/value

The paper develops a revised ACSI model to identify individual critical factors and the degree of effect.

Abstract

Purpose

This study aims to propose a tree‐based analytic tool that may be used in analyzing a large‐scale and complex service process. The tenet of this tool is based on the Boolean logic and named service tree analysis (STA). The proposed STA aims to reflect the customer participation perspective and to propose how to analyze the service process and deduce useful information.

Design/methodology/approach

Fault tree analysis is used as an underlying methodology since it has a Boolean logic to describe the customer's selection of each element and identifies critical events. Taking these advantages of the fault tree, the proposed STA consists of three main parts; service tree construction, qualitative analysis, and quantitative analysis. First, a service tree is constructed depending on how the service elements are selected by the customer; If the subordinate events are always selected by customers, they are linked with an AND gate, otherwise, with an OR gate. Next, in the qualitative analysis, service elements are characterized as core services, supporting services, and optional services by deducing a minimal service cut set. Last, qualitative analysis deals with deriving the impact of each service element based on the Kano model.

Findings

The suggested STA has advantages which help strategic operation and management of the service process.

Originality/value

This study is unique and even exploratory in that it first adopts the notion of tree analysis in structuring a large‐scale, complex service system. Further, the proposed service tree provides a systematic approach from customer participation perspective, which makes the service process to be managed efficiently.

Abstract

Purpose

The open innovation (OI) paradigm suggests that firms should use inflows and outflows of knowledge in order to accelerate innovation and leverage markets. Literature examining how firms are adopting OI practices is rich; notwithstanding, little research has addressed this topic from the perspective of small- and medium-sized enterprises (SMEs). Given the relevance of SMEs in worldwide economies, the purpose of this paper is to provide a comprehensive overview of research on OI in SMEs.

Design/methodology/approach

In total, 112 academic articles were selected from the Web of Science database. Following a bibliometric analysis, the most relevant authors, journals, institutions and countries are presented. Additionally, the main areas these articles cover are summarized.

Findings

Results are consistent in that the most prolific authors are affiliated with the universities leading the ranking of institutions. However, it is remarkable that top authors in this field do not possess a large number of publications on OI in SMEs, but combine this research topic with other related ones. At the country level, European countries are on the top together with South Korea.

Research limitations/implications

Despite following a rigorous method, other relevant documents not included in the selected databases might have been ignored.

Practical implications

This paper outlines the main topics of interest within this area: impact of OI on firm performance and on organizations’ structure, OI as a mechanism to hasten new product development, the analysis of the inbound/outbound dimensions of OI, and legal issues related to intellectual property right management when OI is implemented.

Originality/value

The study uses a combination of bibliometric indicators with a literature review.

Abstract

Purpose

Both system dynamics (SD) and agent-based modeling (ABM) have been used in simulation-based group dynamics research. To combine the advantages of both simulation approaches, the concept of SD-ABM hybrid simulation has been proposed. However, research efforts to compare the effectiveness of modeling approaches between the hybrid and non-hybrid models in the context of group dynamics study are rare. Against this background, this study aims to propose an agent-embedded SD (aeSD) modeling approach and demonstrate its advantages when compared to pure SD or ABM modeling approaches, based on a research case on construction workers’ social absenteeism.

Design/methodology/approach

The authors introduce an aeSD modeling approach to incorporate individual attributes and interactions among individuals in an SD model. An aeSD model is developed to replicate the behavior of an agent-based model previously developed by the authors to study construction workers’ group behavior regarding absenteeism. Then, the characteristics of the aeSD model in comparison with a pure ABM or SD model are demonstrated through various simulation experiments.

Findings

It is demonstrated that an aeSD model can capture the diversity of individuals and simulate emergent system behaviors arising from interactions among heterogeneous agents while holding the strengths of an SD model in identifying causal feedback loops and policy testing. Specifically, the effectiveness of the aeSD approach in policy testing is demonstrated through examples of simulation experiments designed to test various group-level and individual-level interventions to control social absence behavior of workers (e.g. changing work groupings, influencing workgroup networks and communication channels) under the consideration of the context of construction projects.

Originality/value

The proposed aeSD modeling method is a novel approach to how individual attributes of agents can be modeled into an SD model. Such an embedding-based approach is distinguished from the previous communication-based hybrid simulation approaches. The demonstration example presented in the paper shows that the aeSD modeling approach has advantages in studying group dynamic behavior, especially when the modeling of the interactions and networks between individuals is needed within an SD structure. The simulation experiments conducted in this study demonstrate the characteristics of the aeSD approach distinguishable from both ABM and SD. Based on the results, it is argued that the aeSD modeling approach would be useful in studying construction workers’ social behavior and investigating worker policies through computer simulation.

Abstract

From 1953 to 1961, the South Korean economy grew slowly; the average per capita GNP growth was a mere percent, amounting to less than $100 in 1961. Few people, therefore, look for the sources of later dynamism in this period. As Kyung Cho Chung (1956:225) wrote in the mid‐1950s: “[South Korea] faces grave economic difficulties. The limitations imposed by the Japanese have been succeeded by the division of the country, the general destruction incurred by the Korean War, and the attendant dislocation of the population, which has further disorganized the economy” (see also McCune 1956:191–192). T.R. Fehrenbach (1963:37), in his widely read book on the Korean War, prognosticated: “By themselves, the two halves [of Korea] might possibly build a viable economy by the year 2000, certainly not sooner.”

Abstract

Purpose

The evolution of technology has become the mainstream of the current technological innovation era. Technological change is organized in its unique pattern and a new approach that takes place in a systematic and selective manner. Such change is generally molded with the amalgamation of various factors, namely, economic, social or scientific and technological. This paper aims to focus on identifying technological trajectories in a technological ecosystem with the case of m-payment technology.

Design/methodology/approach

This study constructs a patent citation network for mobile payment service technology through patent citation data and identifies the main evolution process using the main path analysis of the network. The scope of this study focuses on key innovation using social network analysis and patent citation network, validated using the case of a mobile payment system and analyzing its technological trajectory.

Findings

Analyzing technology evolution provides a greater insight of the overall technology landscape to the researcher and practitioner. Analyzing the m-payment technology landscape gives three main categories of m-payment systems: the mobile financial transaction system), the payee mobile device payment selection system and e-wallet services.

Originality/value

The novelty of this research lies in the process of identifying technological evolution using social network and patent citation network analysis. The case of m-payment technology ecosystem is studied quantitatively which is not explored by previous researchers. This research provides a way to develop the main path technology of innovative products or services to identify technology evolution using the case of m-payment landscape.
