Watching the speed by which Information Technology (I.T.) has changed over the last forty years has been amazing. Hardly a day goes by without some new twist or invention. In particular, my interest is in how I.T. can be applied to support the systems needed to operate a business, such as for manufacturing, inventory, order processing, customer service, accounting, human resources, and much more. I have seen a lot during the last four decades, perhaps too much.

Since when were Business Analysts a one stop shop for all project needs? We are expected to be Superheros; well-rounded BAs as well as Change Managers, Test Analysts, Project Managers and Implementation Managers. The boundaries of these other disciplines is often unclear so this article seeks to explore the activities that fall into business analysis and those that should be undertaken within the other disciplines.

It appears to me people still have trouble defining information requirements and, as such, they are at a loss as to how to build total systems. Thereby, they are content building either a single business process or a program. Therefore, here is the conceptual foundation for all system design. Information Driven Design begins with a simple concept...

While others are moving forward introducing new banking products, the Americans find themselves in the role of constantly fighting fires. You cannot move forward until you put your house in order by bringing standard practices and discipline into your work effort. This is what happens when you treat system design as an art form, as opposed to a science.

This article extends design thinking into a process and method that uses a range of common Business Analysis techniques to drive engagement through collaboration. It provides more structure to either side of the creative process to one better frame the domain of concern, and secondly after creativity has produced ideas, to prototype, refine, test and learn. The article also positions this process as a better way to arrive at a business case or pre-project phase, since it provides enormous insights through an engaging discovery process; something that would never occur within a traditional environment into investigation investment feasibility.

In a recent Information Technology discussion group I am involved with, someone posed the question, "What is complexity?" I was surprised by the question as I thought it was understood what complexity was all about. Evidently not. The person posing the question was primarily concerned with complexity in system design...

 They took a software approach for designing MIDAS as opposed to a system approach. For example, they probably created a data base quickly, then tried to figure how to get data in and out of it. I would suspect the program source code was well written, probably using "Agile" techniques, but the fact remains none of it was designed to work in a concerted manner.

Based on requirements, ASE decomposes a system into its sub-systems (business processes), the procedural work flow for each, and determine what programs are necessary to implement the computer procedures (software specs). To do this, we determined there were three basic types of sub-systems...

...the fact remains, you cannot build anything of substance, be it a system or otherwise, without a methodology. The question then becomes, how to construct a methodology suitable for your company or a given project. To this end, I offer this tutorial on designing methodologies.

People ask me why I seem to be “black and white” on so many issues. Two reasons come to mind: first, I learned early in school that you do not get credit for making a mistake. If this has changed, please let me know. Second, the nature of my work in the information systems world has taught me there are right ways of doing things, as wel...

I have had business friends over the years ask me why it seems so difficult and time consuming to upgrade their corporate systems to take advantage of the latest computer technology. In their minds, their systems are relatively simple; the concepts of such things as accounts receivable, accounts payable, inventory, manufacturing, etc. are relatively straight forward. Yet, companies incur millions of dollars in keeping them up-to-date. The question is, "Why?"

In this day and age of “globalization” more and more Information Systems are crossing geographical boundaries. Because of this, serious consideration should be given to making systems universally applicable to any country. Some might consider this an impossible task, but it is actually easier than you might think. It just requires a little common sense and some planning.

I never really understood the hubbub associated with system design. People tend to look upon it as a complicated process. Actually it's not, yet the corporate landscape is littered with disastrous system projects costing millions of dollars, all because developers overlooked some rather simple principles for design and focused on technology instead.
