Smart consumer products are designed to provide their users with various benefits. To utilise smart products and enjoy their benefits, users usually have to provide some kind of information to the product and its manufacturer—often personal data. This can raise privacy and data security concerns and may hamper the use of smart products. The Europea...

Next-generation cryptocurrencies based on distributed ledger technology promise feeless value transactions, which may impact existing micropayment business models and make new ones possible. In this paper, we discuss corresponding opportunities and also address challenges as well as respective research perspectives. In a nutshell, business models b...

Agent-based simulation has become an established method for innovation and technology diffusion research. It extends traditional approaches by modeling diffusion processes from a micro-level perspective, which enables the consideration of various heterogeneous stakeholders and their diverse interactions. While such a simulation is well suited to ca...

In the past, most companies in the European apparel industry focused on minimizing manufacturing costs in the design of supply chains in conjunction with long-distance shipping from production sites in the Far East and relatively long production cycles. Today, for some market segments, the speed of production cycles is more important than the cost...

Market diffusion of new products is driven by the actions and reactions of consumers, distributors, competitors, and other stakeholders, all of whom can be heterogeneous in their individual characteristics, attitudes, needs, and objectives. These actors may also interact with others in various ways (e.g., through word of mouth or social influence)....

Information and data fuel businesses and markets; thus, provision, generation, and interpretation of information and data are crucial to support managerial decisions. We demonstrate the generation of information through choice-based conjoint analysis using the example of electric vehicle charging. There are several alternatives for electric vehicle...

It is not easy for students or junior managers to obtain first-hand experience in innovation and technology management. Business gaming simulations can remedy this, as they provide an opportunity to acquire practical skills. We developed such a business gaming simulation that enables teams of participants—each managing a virtual company that compet...

Upcoming cryptocurrency approaches claim to enable feeless micropayments. Assuming that this promise will be kept, this is likely to give rise to new business models that entail transactions worth fractions of a cent. In this mini review, we describe two exemplary application cases and outline the associated research activities for each. The first...

On the occasion of the 65th birthday of Prof. Dr. Rudolf Vetschera, colleagues from all over the world contributed their works in order to compile an issue that is meant as a tribute to his achievements, wisdom, and kindness.

Digital innovation laboratories (DILs) constitute a promising approach to supporting a firm’s digital transformation. Whereas the firm’s existent departments, which form the so-called performance engine, can keep focusing on daily operations, the DIL representing the innovation engine executes digital innovation tasks. Cooperation between the perfo...

Overview Smart connected products are transforming existing markets and creating new ones. The smart homes market is one popular example. This transformation is particularly challenging for large, traditional industrial manufacturers that often rely on organizational structures that have evolved over decades. To adapt, some companies collaborate wi...

Sometime, many (maybe all) vehicles on our streets will drive autonomously - or at least have autonomous functions. However, in the short run, consumers' preferences regarding the automation of pivotal vehicle functions are not entirely clear. This paper accordingly investigates consumers' willingness to use three levels of automation (none, partia...

Numerous “smart” consumer products are already available on the market, and the diversity of such smart products is expected to increase considerably in the future. However, use diffusion of these products is hampered by consumers’ lack of trust toward smart products. Accordingly, trust must be built in smart products before companies (and society)...

Technology transfer to society is—in addition to research and teaching—widely acknowledged as a third mission of modern universities. Academic entrepreneurship and academic patenting are two closely related means to do so and, more often than not, patenting activity and entrepreneurship are part of a linear sequence in the commercialization process...

Intelligente Produkte werden in den kommenden Jahren viele bestehende Konsumgütermärkte verändern bzw. neue Märkte schaffen. Für Innovationsmanager, die für die Entwicklung und Markteinführung solcher Produkte mitverantwortlich sind, stellt sich damit die Frage nach dem Einfluss der wahrgenommenen Produktintelligenz auf den empfundenen Produktnutze...

Real-life examples have demonstrated that technological advantages might not be sufficient to establish a leading market position. Insights into the emergence of a so-called dominant design are therefore not only of academic interest but are also of practical relevance. In the past, the paths leading toward a dominant design have typically been exa...

Nachdem unternehmensspezifische Szenarien erstellt worden sind, stellt sich die Frage nach den „besten“ Handlungsoptionen.

Eine Kombination dieser beidenMethoden kann die Entscheidungsgrundlage für die strategischeTechnologieplanung verbessern. Dazu werden die Auswirkungen vonunterschiedlichen Technolo...

Labelling product innovations as designed and/or selected by customers can positively affect non-participating consumers' self-stated behavioural intentions, that is, it can increase the probability of purchasing that product. Most previous studies have used fictitious brands to test the aforementioned effect, raising concerns about the degree to w...

Consumer adoption of innovations is a key concern for strategic management in many companies as adoption ultimately drives the market success of new products. The respective adoption processes are inherently complex due to the social systems (i.e., the respective consumer markets) from which they arise. Markets characterized by the simultaneous pre...

In the Internet of Things (IoT) consumer products like coffee machines and smoke detectors are connected with the Internet, which effectively expands the Internet to the physical world. Such products have the ability to collect and share data from the user’s environment and, thus, their broad emergence will affect well-established concepts presente...

Many firms resort to scenario analysis as a tool for supporting strategic technology planning. For this purpose, alternative future scenarios are set up and contrasted with potential courses of action that take into account, for instance, new product features, measures for market introduction, or novel business models. Typically, the fitting betwee...

Smart products not only provide novel functionalities, but also may establish new business models, markets, or distribution channels, strengthen relationships with consumers, and/or add smart remote services. While many technical obstacles of such products have already been overcome, the broad market dissemination of smart products still poses some...

The internet of things (IoT) paves the way for a new generation of consumer products that collect and exchange data, constituting a new data source for enterprise information systems (EIS). These IoT-ready products use built-in sensors and wireless communication technologies to capture and share data about product usage and the environment in which...

Despite the prominence of the World Wide Web in people’s everyday lives, most Web presences in private sector organizations still fail to comply with contemporary accessibility standards. As a consequence, a large group of users—i.e., people with impairments—are excluded from accessing these Web presences. In order to explain the managerial rationa...

Organizations’ information infrastructures are exposed to a large variety of threats. The most complex of these threats unfold in stages, as actors exploit multiple attack vectors in a sequence of calculated steps. Deciding how to respond to such serious threats poses a challenge that is of substantial practical relevance to IT security managers. T...

When designing secure information systems, a profound understanding of the threats that they are exposed to is indispensable. Today’s most severe risks come from malicious threat agents exploiting a variety of attack vectors to achieve their goals, rather than from random opportunistic threats such as malware. Most security analyses, however, focus...

Simulation-based optimization with multiple objectives is a challenging problem that is relevant in a broad range of application domains. A common characteristic of these problems is that they are computationally expensive because (i) the size of the search space is vast for nontrivial problem instances and (ii) the simulation-based evaluation of e...

Experimenting with multi-channel operations in reality is both costly and risky, because it can severely affect a firm’s revenues, profitability, customer churn, and other customer metrics. In this paper, we introduce an agent-based simulation approach as a means for exploring and analyzing the impact of (combinations of) multi-channel activities o...

When introducing a new product into market, substantial amounts of resources are put at stake. Innovation managers therefore seek for reliable predictions of the respective innovation diffusion process. Making such predictions, however, is challenging, because the diffusion trajectory is affected by various factors such as the type of innovation, i...

Given the increasing relevance of intellectual property rights as well as the abolition of the professors' privilege in many countries, universities are becoming more interested in filing the inventions of their scientists as academic patents. This may have various implications on research, teaching, and/or administration at universities. The liter...

Marketing activities support the market introduction of innovative goods or services by furthering their diffusion and, thus, their success. However, such activities are rather expensive. Managers must therefore decide which specific marketing activities to apply to which extent and/or to which target group at which point in time. In this paper, we...

Today, information systems are threatened not only by the opportunistic exploitation of particular technical weaknesses, but increasingly by targeted attacks that combine multiple vectors to achieve the attacker's objectives. Given the complexities involved, identifying the most appropriate measures to counteract the latter threats is highly challe...

Market introduction and diffusion of new products is complex and multifaceted since it involves spatially dispersed customers with individual preferences who may be exposed to a wide range of influences including word-of-mouth communication within a social network. During the past decade agent-based modeling approaches for simulating this process h...

The progress in context-aware systems is predominantly technology-driven, leading to innovations in technology-savvy industries while having almost no impact on other industries, such as the insurance sector. In this paper we introduce a novel, key player-oriented framework that explicitly takes into account the (business) value for each player bei...

We outline a methodological framework that accounts for characteristics of the organization, its information infrastructure, assets to be protected, the particular threat sour...

Mathematical modeling of innovation diffusion has attracted strong academic interest since the early 1960s. Traditional diffusion models have aimed at empirical generalizations and hence describe the spread of new products parsimoniously at the market level. More recently, agent-based modeling and simulation has increasingly been adopted since it o...

In the project ‘Competence-Driven Project Portfolio Analysis’ (CDPPA), an integrated system for supporting R&D project selection, staff assignment and activity scheduling with special consideration of the strategic development of competencies has been designed and implemented prototypically. The system has been field-tested at the Electronic Commer...

To adopt or not to adopt an innovation is a question that is ultimately answered by individual (prospective) customers. Their behavior is of practical relevance because it drives the market success of new products or services and it also constitutes an interesting area for academic research. In the course of a research project at the University of...

We compare two visualization methods for interactive portfolio selection: heatmaps and parallel coordinates. To this end, we conducted an experiment to analyze differences in terms of subjective user evaluations and in terms of objective measures referring to effort, convergence, and the structure of the search process. Results indicate that subjec...
