  • Long Live the .250 Hitter
    The dearth of women in computing is very much on everyone's mind. Elena Strange offers a new perspective on this. She observes that the solid, utility hitters (and players) are the backbone of every baseball team. In playing on her computing teams she has no aspirations for MVP awards and strives for personal excellence in the things she does. She asks her male colleagues to value her as a .250 hitter without holding her to the standard of a .314 hitter. This simple change could open the gates to a flood of women in computing. Elena holds Grace Hopper as the equivalent of the legendary .314 hitter in computing. Hopper told her friends that she was never aspiring to be a legendary leader, but only to do the best possible job with the tasks that were before her. Be personally excellent and interact with people from your heart, said Hopper, and all the rest will take care of itself. You can see in Elena's story the seeds that Grace Hopper planted.
  • An Interview with Frans Johansson: The Medici Effect
    In this time of recession, innovation has jumped to the fore in many people's minds. How can we create new value through innovations and pull our individual companies out of the doldrums? In 2004, Frans Johansson published his book, The Medici Effect, in which he discussed how crossing community boundaries leads to innovations, and he said that the most effective way to create the crossing is to mix people from the communities in a common setting. John Gehl spoke with Johansson shortly after the book was published. Johansson's words are worth thinking about now as we reflect on what we all must do next.
  • An Interview with Randy Pausch: Immersed in the Future: On the Future of Education
    Before he became ill, Randy Pausch spoke with Ubiquity Editor John Gehl in 2005. The declining enrollments in computer science were already very much on his mind. At that time, they were down 23 percent. Pausch called this a "huge problem". He noted that, even for those committed to teaching programming from the outset, kids programming in Alice were far more engaged than those trying to find Fibonacci numbers. The enrollments have since declined another 25 percent and the problem is even "huger" than before. Randy's ideas about what turns kids on are even more important today. --Peter Denning, Editor
  • The Power of Dispositions
    Many people have been trying to come to grips with the new ways of learning that are supported by networked tools in recent years. These new ways feature distributed social networks at their core and are proving to be much more popular and often more effective than traditional schooling. Science communities such as faulkes-telescope.com and labrats.org, and massive multiplayer games such as World of Warcraft, are in the vanguard. John Seely Brown and Doug Thomas make an important contribution to understanding what makes these networks so powerful. They use the term disposition to refer to an attitude or stance toward the world that inclines the person toward effective practice. They find that a "questing disposition", which has always been important for inquiry and learning, is encouraged and supported in these vanguard social learning networks. Their work will reward your time and attention. --Peter Denning, Editor
  • An Interview with Michael Schrage
    It is November 2008 and much of the globe is in the throes of recession. Innovation is on many minds. We need new products and new services generating new value for our customers and our companies. It is more important than ever to innovate. The problem is that our collective success rate is abysmal -- 4 percent according to Business Week in August 2005. As we set out on new innovation initiatives, it is a good time to reflect on the illusions that drag our success rates so low. One illusion is that is innovation is a novel ideal or product, another is that those who spend more on R&D get more innovation, and another is that innovation is about great inventions. Michael Schrage of MIT has been challenging these illusions for a long time. He discussed them with Ubiquity editor John Gehl in February 2006. Now is the perfect time to reflect again on what Michael has to say to us about innovation. --Peter Denning, Editor
  • Presidential Politics and Internet Issues in the 2000 Election
    As with the US election of 2000, the US election of 2008 features two slates and four new faces running for the top offices. While many of the issues concerning the electorate are different in 2008 than in 2000, remarkably some issues are the same. We thought you might be amused at Doug Isenberg's resurrected reflections on the 2000 election. You can see what has changed and what has not.
  • Mirrorware
    As we use and design computing systems, Michael Schrage asks us to reflect on what these systems reveal of ourselves and not just what they reveal to others. We may find many surprises about design and privacy. In 1892, the newspapers published a series of editorials of leading thinkers about what the world would be like in 1992. (See Dave Walter, TODAY THEN, Am Geographical Union, 1992.) Collectively, they were almost 100 percent wrong. Their reflections revealed more about how they saw themselves than about the future. This is exactly what Michael Schrage is warning us about.
  • An Interview with Terry Winograd: Convergence, Ambient Technology, and Success in Innovation
    Terry Winograd is Professor of Computer Science at Stanford University, where he directs the program on human-computer interaction. His SHRDLU program done at the MIT AI Lab was one of the early explorations in natural language understanding by computers. His book with Fernando Flores, Understanding Computers and Cognition, critiqued the underlying assumptions of AI and much of computer system design, and led to completely new directions in those fields. He was a founder and national president of Computer Professionals for Responsibility. His remarks, made in 2002, are as relevant today as they were when first spoken.
  • Why Does Time Go Faster As We Get Older?
    Persons in every age group wonder why time seems to move so much faster than it did in their pasts. It seems as if there is never enough time to get everything done and that the situation only gets worse. Many explanations have been offered for this, but few seem to hit the target as well as Phil Yaffe's explanation. We hope you enjoy and find it provocative. Phil has been a writer and journalist for over four decades and is able to write eloquently about his personal experience with accelerating time.
  • The Three Acid Tests of Persuasive Writing
    If there are still scientists toiling away with little regard for what others may think of their efforts, it's time to drag them kicking and screaming into the 21st century. In today's interconnected world, what scientists do is of vital concern to the wider public. And vice versa. Just consider the controversies surrounding nuclear energy, genetic engineering, telephone antennas, global warming -- and even the effects of computers on education and individual liberty (surveillance society).
  • My Problem with Design
    I was reminded today of the things I find troubling about our modern notions of design and designing. Hundreds of years ago, if one wanted to become a designer, one would first have become a master craftsperson. We learned how to construct distinctive artifacts (and worlds of artifacts) and then we began to innovate in that tradition. To say one was a designer without that background would have been Harry Potteresque: ridiculous.
  • Information, DNA, and Change Through the Prism of a Great City
    After retiring from a career in academic/IT management at Carnegie-Mellon, Northeastern, and Washington and Lee Universities, John Stuckey is serving as Acting Chief Technology Officer at the American University in Cairo. This is the third of his reports to Ubiquity from Egypt.
  • Emergence of the Academic Computing Clouds

    Computational grids are very large-scale aggregates of communication and computation resources enabling new types of applications and bringing several benefits of economy-of-scale. The first computational grids were established in academic environments during the previous decade, and today are making inroads into the realm of corporate and enterprise computing.

    Very recently, we observe the emergence of cloud computing as a new potential super structure for corporate, enterprise and academic computing. While cloud computing shares the same original vision of grid computing articulated in the 1990s by Foster, Kesselman and others, there are significant differences.

    In this paper, we first briefly outline the architecture, technologies and standards of computational grids. We then point at some of notable examples of academic use of grids and sketch the future of research in grids. In the third section, we draw some architectural lines of cloud computing, hint at the design and technology choices and indicate some future challenges. In conclusion, we claim that academic computing clouds might appear soon, supporting the emergence of Science 2.0 activities, some of which we list shortly.

  • Wot do U think? (What Do You Think?)
    (NOTE TO READERS: Out of sheer curiosity I used a website that allowed me to translate text from English to the language used by those who send and receive text messages. The second part of this article contains a copy of the entire text that was thus translated.)
  • Technological Transformation of Human Experience
    This article was inspired by Don Ihde's work on the experience of technology in human-machine relations. (See Don Ihde. "The Experience of Technology," Cultural Hermeneutics, Vol. 2, 1974, pp. 267-279.)
  • Professor Andy Clark on Natural-born Cyborgs
    Bio of Dr. Clark: Dr. Andy Clark is a professor of philosophy and chair in logic and metaphysics at the University of Edinburgh in Scotland. Previously, he taught at Washington University at St. Louis and the University of Sussex in England. Clark is one of the founding members of the Contact collaborative research project, whose aim is to investigate the role environment plays in shaping the nature of conscious experience. Dr. Andy Clark research interests include philosophy of mind, artificial intelligence, including robotics, artificial life, embodied cognition, and mind, technology and culture. Dr. Clark's papers and books deal with the philosophy of mind and he is considered a leading scientist in mind extension. He has also written extensively on connectionism, robotics, and the role and nature of mental representation.
  • Thoughts on the Nature of the Virtual
    This article seeks to formulate some brief sociological and philosophical thoughts on the radically problematic nature and character of the virtual. These ultimately aim to critically challenge and reinvent the complex interrelations of contemporary virtuality to the real and the political. In such a context, new media studies acquire a normative impetus.
  • Can Learning Languages Help You Better Understand Science and Technology?
    "I was 24 years old when I first began thinking and speaking in a foreign language. It was like being released from prison. I saw my cell door swinging open and my mind flying free. That was over 40 years ago, but the picture is as fresh now as if it had just happened."
  • An Interview with Richard A. Demillo
    Richard A. DeMillo is the Dean of Georgia Tech's College of Computing. He previously was Hewlett-Packard's chief technology officer and served as director of the Georgia Tech Information Security Center. Under DeMillo's leadership, Georgia Tech's College of Computing has replaced the core curriculum for undergraduates with an ambitious and innovative Threads program, as he explains in this interview with Ubiquity's editor-in-chief John Gehl.
  • Dimension of Philosophy of Technologies: Critical Theory and Democratization of Technologies
    Philosophy of technology promises the possibility of an understanding of technology that may be important not only to public policy but also in helping to conceptualise intellectual approaches to the study of technology and, indeed, to shaping new fields of knowledge and research. Philosophy of technology may also have a role to play in relation not only to structuring a largely disparate and inchoate field but also more directly in teaching and learning about technology (Peters, et. al 2008).
  • Information technology as an ethical challenge
    Information technology has an ambiguous impact on society. This situation calls for a two-level ethical analysis. On the one hand the issues of power and control must be reconsidered under the viewpoint of institutional structures, i.e., of living norms. On the other hand, the technological shaping of society, taking the character of power, oppression, verbosity and dogmatic belief, should be at the same time reconsidered under the viewpoint of a plurality of living forms, i.e., within a framework of deliberation and dissent. This paper presents briefly both issues, taking into account Michel Foucault's concept of "technologies of the self."
  • 21st Century Information Technology Revolution

    The computing power in the few micro processors that are now in a Ford Motor Car is much more than all the computing power that was put in the space vehicle that landed the first men on the moon and brought them back. In today's do-more-with-less business environment, with increasing demands from customers, shareholders, and regulators, the IT organization is not only asked to work harder and smarter, but is being asked to take on the role of assuring the business.

    Humanity has progressed from agricultural revolution to the industrial revolution and is now moving to an information revolution. It is this awesome computing power at continuously falling prices and the computers being networked over global telecom highways that is leading to the use of Information Technology in every sector of human activity be it communication, banking, trading, learning and teaching, entertainment, socializing, government, management and librarying. Just as machines have extended man's mechanical power and his convenience and comfort, Information Technology as commonly picturized by computers, is extending man's mind or brain or intellectual power. The term information technology has ballooned to encompass many aspects of computing and technology, and the term is more recognizable than ever before.

  • An Interview with Wei Zhao
    Wei Zhao is currently the Dean of the School of Science at Rensselaer Polytechnic Institute. Before he joined RPI in 2007, he was a Senior Associate Vice President for Research at Texas A&M University. Between 2005 and 2007, he also served as the Director for the Division of Computer and Network Systems in the National Science Foundation. He completed his undergraduate program in physics at Shaanxi Normal University, Xi'an, China, in 1977. He received his M.Sc. and Ph.D. degrees in Computer and Information Sciences at the University of Massachusetts at Amherst in 1983 and 1986, respectively.

  • Technology based outsourcing K-12 mathematics and science teaching

    The author suggests that the teaching of mathematics and science in K-12 schools be outsourced to teachers in other countries whose students achieve better in mathematics and science. He outlines the advantages of using telecommunications technologies to outsource the teaching of mathematics and science.

  • Scarce resources in computing
    How we organize computing - and innovate with it - is shaped by what at any time is the most scarce resource. In the early days of computing, processing (and, to a certain extent, storage, which up to a point is a substitute for processing) was the main scarce resource. Computers were expensive and weak, so you had to organize what you did with them to make as much out of the processing capacity as possible. Hence, with the early computers, much time was spent making sure the process was fully used, by meticulously allocating time for users on the machine - first with scheduled batch processing, then with time-sharing operating systems that rationed processing resources to users based on need and budget.
  • The non-autonomy of the virtual: philosophical reflections on contemporary virtuality

    Much contemporary talk of virtual 'worlds' proceeds as if the virtual could somehow be considered as in competition with or as an alternative to the world of the 'nonvirtual' or the 'everyday'. This paper argues that such a contrast is fundamentally mistaken, and that the virtual is not autonomous with respect to the everyday, but is rather embedded within it, and an extension of it.

  • Preface by Arun Tripathi to Jeff Malpas' 'The Non-Autonomy of the Virtual'
    Australian philosopher Jeff Malpas, author of Place and Experience, argues in his Ubiquity paper The non-autonomy of the virtual: philosophical reflections on contemporary virtuality that the virtual is not autonomous with respect to the everyday, but is rather embedded within it, and an extension of it. Within philosophy, Professor Malpas is perhaps best known as one of a small number of philosophers who work across the analytic-continental divide, publishing one of the first books that drew attention to convergences in the thinking of the key twentieth century American philosopher Donald Davidson and the phenomenological and hermeneutic traditions, as exemplified in the work of Heidegger and Gadamer.
  • Employee retention: By way of management control systems

    Loyalty is passé in the modern time and professionalism is the buzzword in the contemporary corporate world. The reasons of employee attrition are also changing. Now-a-days employee leaves an organization for many reasons. Some leave for growth, some leave for some family problems but majority of people switchover jobs due to only one reason that is DISSATISFACTION. Undoubtedly satisfaction and dissatisfaction sort of things have different meaning for different people but having majority of people satisfied is pretty germane for sustainable growth and high level of productivity in any organization. A threadbare analysis of attrition brings some major concerns like not having objectivity in job allocation, employee recognition and fairness in career advancements for consideration. They are also important causes of dissatisfaction for employees in organizations. This dissatisfaction finally gets a vent in the form of changing the job. This subjectivity in the issues of employee handling is the key for dissatisfaction. Management Control System is fully capable of bringing objectivity in the organization and managing this dissatisfaction which would finally be translated into high employee retention, and better productivity and better organizations.

  • Mental Models: Aligning design strategy with human behavior
    I ndi got her BS in Computer Science from Cal Poly and began her master's at Colorado State. She then worked as a software engineer, later managing Web applications that focused on the user. Her concepts in mental models derive from attempting to bridge the developer-user gap. Her expertise ranges from structuring crossfunctional teams, to managing participant recruiting, and conducting user interviews, thereby creating effective tools for exchanging results.
  • How to use presentation slides to best effect
    How often have you attended a presentation where great attention apparently went into designing the slides - and apparently none into how they were used? Or the speaker played with the slides as if to entertain rather than edify?
  • Smart phones: A tutorial
    1. INTRODUCTION Pervasive Computing integrates computation in the environment rather than computers which are distinct objects. Other terms for pervasive computing ubiquitous computing, calm technology, things that think and everyware. In other pervasive computing means computers everywhere, making them available the physical environment while making them effectively invisible to the user. having a desktop or a laptop machine, the technology pervasive computing embedded in the environment. Ubiquitous technology is often wireless, networked making its users more connected to the world around them and the it. Through pervasive computing, users use today's digital tools like laptops, phones, PDAs, smartphones to communicate and exchange information in different and conceive and use the geographical and temporal spaces differently. In being an aspect of information dissemination, pervasive or ubiquitous computing global and local, social and personal, invisible and visible at the same time.
  • The rise and fall of a good programmer
    Of all the sayings I dislike, the most vapid is one I have heard as long as I have been working with IT: We will have the paperless toilet before we have a paperless office. Normally uttered with a dry cackle and a finger pointed towards my office, which does not lack for paper.
  • Time to get serious about the paperless office
    Of all the sayings I dislike, the most vapid is one I have heard as long as I have been working with IT: We will have the paperless toilet before we have a paperless office. Normally uttered with a dry cackle and a finger pointed towards my office, which does not lack for paper.
  • An Interview with Vaughan Merlyn on Management
    Vaughan Merlyn, who is a management consultant, researcher, and author, has had as his primary focus for more than three decades now has been the use of information and information technology for business value creation. He was interviewed about software consulting and management.
  • Avoiding disaster when your hard drive fails
    No one really expects a disk crash, but they do happen, usually at the most unconvenient times. Having a quick and easy-to-restore backup can eliminate both the distress and expense of the prolonged downtime normally associated with a hard drive failure. When restoring from a drive failure, the best kind of backup to have is an image backup.
  • Anticipating and resolving resource overloads
    The Concept of a Project Resource In the context of project management, a resource is any entity that contributes to the accomplishment of project activities. Most project resources perform work and include such entities as personnel, equipment and contractors. However, the concept of a resource (and the techniques of resource management presented in this paper) can also be applied to entities that do not perform work, but which must be available in order for work to be performed. Examples include materials, cash, and workspace. This paper focuses on the resource that is of greatest concern to most organizations personnel. In a project management system, personnel resources may be identified as individuals by name or as functional groups, such as computer programmers.
  • Why visual aids need to be less visual
    I was recently invited to a presentation by an accomplished speaker. Needless to say, his speech was well structured, his manner relaxed and confident, his eye contact and body language excellent, etc. He normally spoke without slides, but this time he felt they would reinforce and illuminate his message. They didnt. In fact, they were more of a hindrance than a help.
  • Interview with MIT's Robert Langer
    Dr. Robert Langers work is at the interface of biotechnology and materials science. A major focus is the study and development of polymers to deliver drugs, particularly genetically engineered proteins, DNA and RNAi, continuously at controlled rates for prolonged periods of time.
  • Out sourcing-off shoring: how will you derive the value?
    The equations of global economies are changing fast due to Industry consolidation, merging, acquisitions and on account of industries hunger for global hunt and race of scaling-up higher and higher there by creating stiff competition among their rivals. The business houses are deeply evolved in looking at techno commercially viable IT solutions to grow at faster speed, support the business effectively and provide competitive advantage by using the latest emerging technologies.
  • Arrogance or efficiency? a discussion of the Microsoft office fluent user interface
    1 Introduction I was writing an e-mail message the other day using Microsoft Office Outlook 2007 and clicked on the button for adding one of my signature blocks. Presto! Most of my message disappeared! Investigation and testing showed that the behavior was unpredictable; sometimes, only the existing default signature was replaced by the new signature but occasionally the program became confused and wiped out portions of the text as well.
  • Is a worldwide common language just over the horizon?
    I am an American living in Belgium since 1974. Ever since arriving here, I have been hearing the mantra To be a good European, you should learn several languages. Almost from the very beginning, I suggested going the other way: To be a good European, everyone should learn a single common language.
  • Why track actual costs and resource usage on projects?
    The importance of tracking actual costs and resource usage in projects depends upon the project situation. For some projects, tracking actuals is unnecessary or is not worth the effort required. In other cases, however, tracking actual costs and resource usage is an essential aspect of the project control function. In such cases, a system must be put into place to support the tracking process, and the collection/recording of the potentially voluminous quantity of data requires strong organizational discipline. Why then is tracking actual costs and resource usage on a project ever worth the effort required to accomplish it?
  • An Interview with Dr. Yi Pan of Georgia State University
    Ubiquity is proud to publish this inspirational interview, which starts with a discussion of the creation of the computer science department at Georgia State University, and concludes with the heroic efforts an impoverished student from Tsinghua University in China overcame many obstacles to rise to a significant position at Georgia. The interviewee is Yi Pan, Chair and Professor of Georgia State University's computer science department, who provided us with these inspirational reflections on computer science, academic success, and true success. The interview was conducted by Ubiquity editor-in-chief John Gehl.
  • An Interview with Michael Schrage on Ubiquity
    Author of several acclaimed books and numerous articles in such publications as Fortune and Technology Review, Michael Schrage is also a world-traveling consultant to all businesses great and small. He has been at MIT for many years, and his new academic home will be in that institution's Sloan Management School.
  • Hermeneutics facing the
    The origin of this paper goes back to the International Conference "Phenomenology and Technology" held at the Philosophy and Technology Studies Center, Polytechnic University (New York), October 2- 4, 1986 which was organized by Wolfgang Schirmacher and Carl Mitcham. After thirteen years, obviously, things have changed and I have done some further work too. My book Hermeneutik der Fachinformation was published in 1986 and since then I have written some articles on this subject as well as another book Leben im Informationszeitalter (Capurro 1995). Some of the articles as well as a list of publications can be found in my homepage (http://www.capurro.de). The present text is an enriched version of the original one. I have added some later insights without changing the basic ideas which I still think are valuable and can also be of help when reflecting, for instance, about the nature of communicating and searching for information in the Internet.
  • ERP system replacement criteria

    An ERP system is our information backbone and reaches into all areas of our business and value-chain. Replacing it can open unlimited business opportunities. The cornerstone of this effort is finding the right partner and specialist. Our long-term business strategy will form the basis of the criteria for our selection of an ERP system replacement. Our ERP provider must be part of our vision. It is the duty of a software provider to help us to get there by doing their part to make sure our next system will be our last ERP system replacement. Some of the criteria that allow us to identify and select the solution that will meet these expectations.

  • Whatever happened to cybernetics?
    Has the discipline of cybernetics been unable to recognize and respond to appropriate "midcourse corrections" and in the process had its destiny imposed by external "turning points"? (A mid-course correction is an endogenously determined action as in the classical "sense-processact" sequence, whereas a turning point is simply a reaction to that which is exogenously imposed; i.e., "being overcome by events."
  • Renovation of minimum spanning tree algorithms of weighted graph

    In this paper we describe and explain the Minimum Spanning Tree (MST) generation algorithms of a weighted graph with renovated idea. Here, we used a new cycle testing algorithm for testing cycles, if required, in generation of Minimum Spanning Tree. The reason behind this is to optimize the execution time for cycle testing. Also, we describe some Minimum Spanning Tree algorithms for weighted graph with a renovated idea. We applied here new concept for explanation of minimum Spanning tree with better time complexity.

  • Understanding software testing concepts
    Software testing concepts have been briefly described in this article. Readers would find it easier to understand fundamental concepts of software testing by going through a concept map thereof. Software testing is itself a discipline as well as a process. Software development is nothing but a process of coding functionality in order to meet the defined end-user requirements. We can think of software testing as an iterative process, which consists of Tests Designing, Tests Execution, Problems Identifying and Problem Fixing, for validating functionality and as well as for attempting the software break. Software testing aims to find problems and to fix them for improving software quality. Software testing may represent 40% of a software development budget. Basic methods of performing software testing include Manual Testing and Automated Testing. Manual software testing is the process of manually testing software (having the possible forms for example, user interfaces navigation, information submission, or attempt to hack the software or database etc.), carried out by an individual or individuals. Manual software testing is labor-intensive and slow. On the other hand, automated software testing is a process of creating test scripts, which can be run then automatically, repetitively, and through a number of iterations. Automated software testing helps us to minimize the variability of results, speed up the testing process, increase test coverage (that is, the number of different things tested), and ultimately provide greater confidence in the quality of the software being tested.
  • End laptop serfdom
    Time to end personal technology serfdom! I hate company-specific technology standards, at least those that specify technology in terms other than file formats, access protocols and application programming interfaces. In most companies I am in touch with, employees get a laptop and a cell phone and are required to use a set of standard capabilities of some sort. More often than not these are unnecessarily complicated, old-fashioned, expensive and singularly uninspiring. This is often for good reasons: The IT department wants to make things manageable for themselves and for the organization, and employees need to have a standard frame of reference and a compatible set of tools for work. The helpdesk can figure out which keys to press and the employees can see the same screens. Well and good, but the users are beginning to rebel at the lack of options especially those they have on their own or former computers.
  • About english: On the other hand
    I read Philip Yaffe's two recent Ubiquity pieces with interest, all the more so because I myself have plunged back into an international experience after sampling the delights of retirement for a year.
  • How many Americans does it take to change a light bulb?
    I changed a light bulb yesterday. Or, rather, I had the thing changed. I told an Egyptian friend I had a couple of bulbs burnt out and was assuming I could pick some up at one of the larger new supermarkets. He looked at me with barely concealed pity for my ignorance. No, he said. They don't carry light bulbs in a market. Later, in e-mail, he would spell it "light pulp," which is an image I find quite intriguing. Where's Einstein when you need him? Might light pulp be what glows inside the glass, I wonder?
  • Serial port data communication using MODBUS protocol
    Serial communication is the process of sending data sequentially one bit at a time, over a communication channel or computer bus [5,6,7]. RS-232 is a standard for serial binary data transfer between a data terminal equipment (DTE) and a data circuit-terminating equipment (DCE), commonly used in computer serial ports.
  • Is the GMO controversy relevant to computer ethics?
    Computing and information technology professionals have exhibited high standards of engagement with ethical issues relating to privacy, information security and abuse of the technical capabilities they have been responsible for developing. But one can argue that computing capability is implicated in ethical controversies that receive relatively little discussion within the IT community. Stem cell research, nanotechnologies and other controversial areas of science would be impossible without the computational capacity of information processing. In many instances, the downstream applications of computer technology are deeply involved in the issues surrounding contested technologies.
  • An approach for conducting enterprise resource planning assessment

    The failure to plan will lead to results that fall short of expectations. The same thing can be said of companies and their search for a new Enterprise Resource Planning (ERP) system. All companies undertake the search for a new system because they believe there is an opportunity to improve the organization, either by improving the revenue, decreasing costs or both.

    But far too often, companies undertake this effort without having a plan on how to select a new ERP system. They fall victim selecting the product with the best sales presentation or the best cost proposal. There is not quantitative evidence that this new system will actually achieve the goals of improving the revenue or decreasing the cost.

    So put an evaluation plan in place. No two plans will be the same but all should have the same basic concepts.
