Services Grids in Industry – On-Demand Provisioning and Allocation of Grid-Based Business Services

Over the last few years Grid computing has attracted considerable attention from the industry, because it offers opportunities for new on-demand business services for enterprises. In this article, we depict the current trend of enterprises to source Grid services offered by third-party utility providers on a use-on-demand, pay-per-use basis, thus leading to faster IT response to changing business needs. We outline the emerging expansion of Grid computing in industry and discuss the significant challenges still needing to be solved to further promote the adoption of Grid technology in the business domain.

Perspectives in the Interplay Between Business and Information Systems Engineering and Computer Science

The relationship between business and information systems engineering (BISE) and its main reference disciplines business administration and informatics has changed several times during the last decades. Despite some frictions during the 1980 s and 1990 s, the interplay between informatics and BISE is becoming much more constructive and has proven extremely fruitful. Important examples of this co-evolution include data management and conceptual modeling, internet-based information and transaction systems, and the emergence of computational business sciences. The increasing integration of virtual and real world in the “Internet of Things” offers new scientific and organizational challenges for the cooperation between the BISE and informatics, which can only be formulated and solved jointly.

Optimized Software Licensing – Combining License Types in a License Portfolio

Although software licenses usually range among the most expensive items within the IT budget, they still lack the necessary attention by many companies. Therefore, most companies inadequately have implemented their software asset management neglecting further potential for cost reduction, which can be obtained by optimizing the use of different license types. This paper shows how possible savings can be realized by combining different types of licenses in a license portfolio. The model presented is based on the most common license types considering different user groups as well as their behavior. Additionally to cost risks, the risk of service quality is also taken into consideration. The following examples illustrate the model’s high relevance and show how it can be applied in practice.

The Integrative Effect of Electronic Data Processing

Electronic data processing systems have been constructed based on the results of cybernetics and communication theory. They interpret the combination of several constructs as integrated systems that form integrated systems of a higher degree. This corresponds to the way modern economics looks at corporate functions, enterprises, the economy... This fundamental tendency is reflected by the idea that the most important factor in electronic data processing systems is not the speed of operation but the integrative effect. Therefore it is necessary to arrange workflows in a closed control system, under consideration of the most rational path. Thus IDP advances the aims of business organization to a higher level and at the same time provides means for reaching these aims.

An Analysis of Design Problems in Combinatorial Procurement Auctions

Traditional auction mechanisms support price negotiations on a single item. The Internet allows for the exchange of much more complex offers in real-time. This is one of the reasons for much research on multidimensional auction mechanisms allowing negotiations on multiple items, multiple units, or multiple attributes of an item, as they can be regularly found in procurement. Combinatorial auctions, for example, enable suppliers to submit bids on bundles of items. A number of laboratory experiments has shown high allocative efficiency in markets with economies of scope. For suppliers it is easier to express cost savings due to bundling (e. g., decreased transportation or production costs). This can lead to significant savings in total cost of the procurement manager. Procurement negotiations exhibit a number of particularities:

Simulating Discount-Pricing Strategies for the GSM-Mobile Market

The article analyzes network effects on the German GSM mobile telephony market. The authors use an ACE-approach to examine how a new competitor can successfully gain ground in the market with a discount-pricing strategy. In particular they study the impact of several elements of a mobile phone contract like on-net-, landline- or off-net-fees on the competitor’s market share. It turns out that it is possible to successfully enter the market with a prepaid contract using a discount-pricing strategy where the single fees only marginally exceed the termination rates, which have to be transferred to foreign network operators.

Electronic Computers – The Challenge to Management

The potentialities of computers have not been fully exploited in the U.S. because management has underestimated the task of putting them to proper use. Management has believed that computers themselves are automation. But automation places a premium on good management. Without careful management planning, business resources are wasted in terms of managerial and technical time and abilities. Since computers are capable of handling many tasks simultaneously, it is only by casting aside the departmental concept and substituting the integrated systems approach that the true value of these machines begins to be appreciated. Automatic data processing provides for the tighter control that is important in competitive markets. The key to the whole problem of putting automation to work is education of personnel. Knowledge of equipment and techniques is not enough. Automation, by permitting handling of many jobs simultaneously, is in direct conflict with the concept of division of labor. The businessman, faced with wholesale reorganization of work, must train more basically and broadly. Current training for this field is largely dependent upon specialized courses offered by the manufactures of computers. The responsibility for training these people is largely that of private business, and it is a larger task than most managers realize. If a businessman is to feel confident that his company’s data processing is not just a gamble, he must accept this new challenge to management.

Software to support business teams

Organizations are increasingly using the business team concept to gain competitive advantage. Collaboration support software is gaining acceptance as a viable tool among both researchers and practitioners, and an opportunity exists to investigate the specific needs of teams: users working in longitudinal time frames on a variety of tasks. In this article, team software requirements are first derived from a theoretical perspective: office automation and task literature are used to identify a set of domain-independent individual tasks. Group process literature is then used to develop a set of collaborative tasks composed of these individual task components. These individual and collaborative tasks are aggregated with team task and communication support requirements to develop requirements for an integrated software environment that effectively supports business teams. Design considerations for a comprehensive team support system are outlined, a prototype implementation is described, and project contributions and key future research considerations are summarized.     

Analysis of Informal Communication Networks – A Case Study

The structure and dynamics of informal communication networks are of central importance for the functionality of enterprise workflows and for performance and innovation of knowledge-centric organizations. While most executives are aware of this fact, there is a general lack of (semi-) automated, IT-supported methods and instruments to make informal communication networks measurable. Although logging of electronic communications has made considerable progress over the past few years, it is still extremely difficult to map personal interaction; manual approaches in particular are extremely error-prone. The article shows how informal communication networks can be investigated by IT-based methods. At the same time, the authors will be presenting an instrument (“Social Badges”) that collects personal communications automatically and more precisely than legacy approaches allow. The practical applicability of the approach is evaluated through a case study.

Combining Business Process Reengineering Concepts and Object-Oriented Technology for Effective Organizational Design

Today's business world is facing a plethora of managerial and technological changes beyond the capacity of any firm to control and absorb them. Customer satisfaction, development of new products, and introduction of new technologies are well-known driving forces, but their fast mutation and turmoil are making them unpredictable. Business process reengineering (BPR) is considered the most disruptive approach for designing organizations that can thrive in this turbulent environment. Although there is an increasing number of experiences that testify to its positive results, at present it is used mainly in large companies, and small and medium firms consider it as a risky and expensive activity. Within this framework, this article discusses a methodology for designing and implementing BPR, developed to overcome most of the limits that still bind its diffusion. This methodology supports firms in embedding reengineered processes knowledge owned by organizational units and in integrating available software and hardware, The focus of this article is on linking business and software modeling to allow the development of ad hoc new business processes while reducing risk of wasting time and money for useless requirements or for stiff solutions. The proposed methodology, starting from organizational requirements derived from business modeling, supports the analysis of costs, lead time, and quality or completeness trade-off of developed solutions. The phases of the methodology are discussed in detail together with an application example and results obtained from existing successful applications.     

IT Controlling – Concepts and Transformation into Practice

In the first part the paper depicts central IT controlling terms and selected IT controlling concepts of the last decade. In the second part a performance oriented IT controlling concept describes central processes of the IT controlling concept by using a three step life cycle model in terms of a reference model. Finally some important results from a current survey concerning the development of IT controlling in German speaking countries are given. Based on these facts the paper describes the needs for action in academia and practice: The role of the IT controller has been established in German speaking countries, but there is disagreement concerning targets, tasks and processes of IT controlling, cost oriented tasks and reporting are dominating the practitioner’s work, established economic methods of IT controlling are not consistently used in companies.

Business and Information Systems Engineering Links Science with Entrepreneurship

One of the major success indicators for applied research sciences is the rate of transfer from research into practice. Only if concrete and economically successful products are derived from research results, such sciences can induce an impact. However, this process of innovation mandatorily needs entrepreneurship. Within the domain of business information systems, the two German enterprises SAP AG and IDS Scheer AG demonstrate that linking research and innovation is the key to lasting success on the information technology markets. German industry has significant disadvantages concerning the cost of human resources. Therefore it can be only successful with products that incorporate a high degree of innovation and that are consequently highly priced. But the invention of such products needs scientific research as a source of inspiration. Germany has a highly developed infrastructure of research facilities and organizations. However, they need to be better coordinated and aligned with business needs. Vice versa, enterprises need to actively approach the scientific community in order to clearly formulate their demand. Such a strategy requires changes on all sides. To achieve a change in the domain of science, it is necessary to change the profile of leading researchers, such as full professors. They should incorporate attributes of an entrepreneur and be profiled more as a research manager who tries to anticipate future needs and to develop their unit in terms of research subjects as well as personnel and financial resources. Consequently, the process of application, selection and review of leading researchers should be more oriented on processes that are common in enterprises. E. g. external head-hunters can be involved in the searching and assessing process in order to obtain the best qualified person for the research vacancy. Also enterprises need to change their attitude towards scientific research. In order to foster this process, executives could be invited to advisory and supervisory boards of research organisations. Furthermore, these executives must be proactively informed about the research activities and results in order to attract their interest and to show potentials for a transfer into products. There is still a long way to go in the hunt for innovation leadership and all these suggestions can only be a starting point. Accepted after one revision by Prof. Dr. Buhl.

Detecting Supply Chain Innovation Potential for Sustainable Development

In a world of limited resources, it could be argued that companies that aspire to be good corporate citizens need to focus on making best use of resources. User value and environmental harm are created in supply chains and it could therefore be argued that company business ethics should be extended from the company to the entire value chain from the first supplier to the last customer. Starting with a delineation of the linkages between business ethics, corporate sustainability, and the stakeholder concept, this article argues that supply chains generally have a great innovation potential for sustainable development. This potential could be highlighted with system thinking and the use of change management knowledge, promoting not only innovations within technology but also within organizational improvement. We propose process models and performance indicators as means of highlighting improvement potential and thus breaking down normative business ethics’ requirements to an opertionalizable corporate level: Good business ethics should focus on maximizing stakeholder value in relation to harm done. Our results indicate that focusing on supply chains reveals previously unknown innovation potential that seems to be related to limited system understanding. The assumption is that increased visibility of opportunities will act as a driver for change. Results also highlight the importance of focusing on sustainability effects of the core business and clearly relating value created to harm done.     

A Workflow-Based Methodology for Developing Hypermedia Information Systems

Recently, many enterprises have attempted to construct hypermedia systems for electronic commerce innovation by the use of Internet technologies. In this hypermedia-enabled environment, hypermedia development can be considered in terms of workflow. In this article we propose a workflow-aware hypermedia development methodology, workflow-based hypermedia development methodology, to guide developers in creating hypermedia information systems. The methodology employs a workflow model based on corporate documents and is thus more likely to utilize users' business requirements in a natural fashion. The methodology consists of four phases: workflow analysis, document analysis, hypermedia design, and implementation. The emphasis of each phase is on aligning business requirements with hypermedia development technologies. To demonstrate the practical usefulness of the methodology, a real-life case is illustrated.     

Lotus notes (groupware) in context

Reviewing Notes, or any groupware program, highlights the changing nature of software evaluation. Early reviews, for example, Press (1980), emphasized a program's features, efficiency (memory and storage requirements and speed), and user interface. These have all diminished in importance. With multiple revisions, the feature sets and efficiency of commercial programs for a given application have become relatively similar, and direct‐manipulation user interfaces like the Macintosh and Windows have reduced the differences among the user interfaces of programs.

Today, software (especially groupware) must be evaluated in context. It must be compatible with the skills and requirements of the users and the organization, and it must be well integrated with other software and systems. The stability, support, plans, business arrangements, and so on, of the vendor are also important. The program is the tip of an iceberg.

After describing Notes and its applications, I will discuss the question of its suitability in different organizations and integration with other software and vendors.     

Epistemological and Pedagogical Challenges of Teaching International Business Ethics Courses

International business ethics courses imply four basic epistemological and pedagogical challenges: (a) understanding various perceptions of ethics and values/virtues; (b) identifying ethical maxims among religious/spiritual traditions; (c) designing international business ethics courses as dialogical experiences; and (d) deepening our personal contribution to others’ learning process. This article argues that those epistemological and pedagogical challenges could determine the design and the contents of international business ethics courses: facing up to compatible/incompatible ethical theories (philosophical questioning), identifying ethical maxims among religious/spiritual traditions (religious and spiritual questioning), and reading our actions/decisions as quasi-texts (literature-bound questioning). Business ethics teachers could take those challenges upon themselves and design their business ethics courses accordingly. For each of the four challenges, a specific ethical issue is described; advice for teachers as well as ethical questions for debate and personal development are provided.     

Comparing Business Intelligence and Big Data Skills

While many studies on big data analytics describe the data deluge and potential applications for such analytics, the required skill set for dealing with big data has not yet been studied empirically. The difference between big data (BD) and traditional business intelligence (BI) is also heavily discussed among practitioners and scholars. We conduct a latent semantic analysis (LSA) on job advertisements harvested from the online employment platform monster.com to extract information about the knowledge and skill requirements for BD and BI professionals. By analyzing and interpreting the statistical results of the LSA, we develop a competency taxonomy for big data and business intelligence. Our major findings are that (1) business knowledge is as important as technical skills for working successfully on BI and BD initiatives; (2) BI competency is characterized by skills related to commercial products of large software vendors, whereas BD jobs ask for strong software development and statistical skills; (3) the demand for BI competencies is still far bigger than the demand for BD competencies; and (4) BD initiatives are currently much more human-capital-intensive than BI projects are. Our findings can guide individual professionals, organizations, and academic institutions in assessing and advancing their BD and BI competencies.     

Leveraging collective intelligence: How to design and manage crowd-based business models

Advances in digital technologies have increased the possibilities for outsourcing business activities to crowds of independent contributors. Using the collective intelligence of a crowd opens a new range of business opportunities. In fact, crowdsourcing has led to the emergence of entirely new business models. Such crowd-based business models (CBBMs) can lead to an important competitive advantage while simultaneously presenting new challenges to entrepreneurs and executives. This article identifies and discusses three key challenges in designing and managing CBBMs: determining (1) the crowd's value to the firm, (2) how to create superior value for the crowd, and (3) how to capture value from the crowd effectively. Building on the crowd capital perspective and an analysis of the tactics and practices of successful CBBMs, this article offers propositions on how to overcome these challenges and manage such business models effectively. The identified practices can inspire decision makers when designing innovative CBBMs for their industries. Finally, the article concludes with a framework with the key decisions and tactics for effectively managing CBBMs.     

Quantitative content analysis as a method for business ethics research

The aim of this article is to discuss quantitative content analysis as established in communication sciences as a method for research in business ethics. We argue that communication sciences and business ethics are neighboring disciplines, which allow the transfer of quantitative content analysis from communication sciences to business ethics. Technically, quantitative content analysis can be applied through human as well as software coding. Examples for both applications are provided and discussed. We make reference to the software solutions ‘Leximancer’, ‘Crawdad’, and ‘Wordle’, and examine their suitability and limitations with regard to ethical questions for researching business ethics. We recommend a mixed-method approach, combining human and software coding. Furthermore, we propose a three-step process that discusses quantitative content analysis as a method for business ethics, including an ethical research objective, and most importantly, concluding with ethical reasoning and interpretation of the quantitative results.
