SDLC, Process, and Methodologies

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...

The 3 Amigos (sometimes referred to as a “Specification Workshop”) is a meeting where the Business Analyst presents requirements and test scenarios (collectively called a “feature”) for review by a member of the development team and a member of the quality assurance team.

This is a complete example of a Business/Systems Analysis Model using UML and including: Use Cases, Activity Diagrams, Context Diagram, and more.

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.

Every now and then I encounter a programmer who adamantly contends you cannot have an information system without some form of computer support. Actually, we've had such systems well before the advent of the computer.

A great approach under the right circumstances, agile is not a universal solution for successfully completing a software project. Some projects are simply not compatible with most agile practices. For such projects, NANW has been driving results in terms of project and rework costs, integration time, and improved quality as reported by customers.

Many words have been written about the process of business analysis and how it can be performed on different types of projects. There are a multitude of tools and techniques which can be used plus methodologies and frameworks to suit a wide variety of circumstances. This makes it all too easy to get absorbed in the day-to-day detail and forget about the real purpose of business analysis – to fix a problem or provide the organisation with a new capability.

The purpose of this article is to provide project managers and business analysts an example of choosing a hybrid solution development life cycle (i.e., combination of agile and waterfall). Much discussion has transpired on the virtues of agile and waterfall approaches.  

I’ve written in the past about why hybrid approaches that incorporate traditional and agile methods of software development are been applied by organizations seeking to improve the results of their software projects. Here I’ll describe the 3 types of hybrid projects I have identified while working with different organizations in consulting assignments, and what impact each type has in the work of a business analyst.
