Wildcard DNS?
I have installed a redirection service. How on earth is this script supposed to work if the sudomain has to be set up manually? What I want is Wildcard DNS on my domains, but if I create a new subdomain (or if myred (the script)) creates a new subdomain, then I need it to work.

Is Apple’s Intel Switch the Beginning of a Cinderella Story?
For years the Mac was a highly specialized PC, ignored by most, but loved by certain industry aficionados. But no matter how dearly adored it was for its stability, security, and usefulness in the layout and design professions, it didn’t have the appeal that came with heavy hitter Microsoft and Windows OS.

ePrompter - AIM Address
Does anyone know how to set "ePrompter" to check an AIM email address; e.g: xyz@aim.com? I have to enter in the POP3 Server it seems. I have tried several times, but no luck so far. Thanks for any input on this.

How To Make Your IT Project A Success

By Dr. Gerald M. Hoffman

For an IT project to be a success, it must meet three criteria:

1. it must be completed on time,

2. it must be completed within budget, and

3. it must provide the full functionality originally promised.

The IT profession has been conducting IT projects for over thirty years. Yet about 75% of all IT projects fail to meet one or more of these criteria. Why? The reasons IT projects fail are listed below, more or less in the order of frequency of occurrence:

1. Inadequate or inaccurate specifications

2. Changing specifications

3. Insufficient user support

4. Bad estimates of required resources

5. Technical failure

6. Bad management of the project

At first glance it seems that if in IT project fails, it is the fault of the IT department and the IT people. Without question this is true some of the time. Technical failure is clearly an IT failure most of the time. (Sometimes IT is forced to use questionable technology by the rational demands of the competitive environment, or by irrational demands by users to have the best and latest.) Bad project management is also an IT failure much of the time. The IT community is aware of these failings and is making substantial progress in correcting them.

But there is more here than meets the eye. IT cannot do it alone. Substantial participation by users is essential to the success of every IT project.

Let's look at the role of users in a typical IT project in terms of the specific tasks that need to be done in each phase of development.

  • User requirements specification - Users should do most of the work, with guidance about costs and technical issues from IT.

  • Functional design - Users should lead this effort, with some participation by IT.

  • Technical design - IT should lead this phase, with some input from users, as technical considerations suggest or require change in functional design.

  • Coding - No user participation required.

  • Testing - Users must design the test cases, provide the test data and analyze the test results. This is a larger effort than most people realize.

  • Training and documentation - While IT must create the technical documentation, user documentation of system functionality is best done by users.

  • Implementation - The users must work in parallel with IT to install the new business processes required by every new system, even as they train the ultimate users of the system.

    There is almost no reliable data on how much user time is or should be involved in these activities, but we in the IT community know that the requirements are large. In an attempt to understand the issue, I have conducted over 100 informal surveys of IT professionals in the course of my teaching in the Northwestern University's Communications Systems Strategy and Management program and in various other professional programs and industry seminars.

    The survey consists of just two questions. I set the stage this way: "Think about a typical IT application development project that is now under way or that you have recently completed, and answer these two questions. Express your answer as the ratio of user work days to IT work days."

    Here are the questions and the range of answers I usually receive:

    1. How much user time should the project have had, as a percentage of IT time? Answers typically range from 25% to 50%.

    2. How much user time did the project actually get? Answers typically range from 0% ("They told me to do it, and then disappeared until it was done.") to 15%.

    My analysis tells me that user work time in an application development project should be from 25% to 100% of IT time, depending on the nature of the project.

    If this strikes you as too high, consider our collective experience with comprehensive ERP systems a few years ago. These systems were so large that they required dedicated task forces of users to support their development. In many cases there were more users on the task force than IT people. For the first time, companies were confronted with the magnitude of user support required for major application system development and deployment.

    In no case has any CIO (of over 200 I have surveyed) ever said that any project received as much user time as it required. The gap is usually closed by IT people doing the users' work. This guarantees project failure:
