SDLC, Process, and Methodologies

A change request (CR) is basically any change in the initial set of signed-off requirements. So, typically in a waterfall model implementation, the requirements phase ensures that all the requirements (features/functionalities/functional and non-functional) are agreed upon and documented before development starts. After that, any new scope brought or requested by clients becomes a change request. There is an additional cost associated with implementing a change request.

Even in the agile model of working, although there is flexibility in the implementation of the project, vendors ensure that a high-level set of requirements are discussed and agreed upon. The iterative way of working ensures that clients have their eyes on the product as it is developing and can suggest corrections or alignments. However, no vendor can work with entirely flexible requirements. It's not feasible from a budgeting standpoint.

There’s always more than one design solution for a software problem and seldom a single best solution. The first design approach you conceive won’t be the best option. As one experienced designer explained it:

You haven’t done your design job if you haven’t thought of at least three solutions, discarded all of them because they weren’t good enough, and then combined the best parts of all of them into a superior fourth solution. Sometimes, after considering three options, you realize that you don’t really understand the problem.

These are my findings from analyzing the Business Analysis Body Of Knowledge, version 3 (BABOK). These findings are presented in the form of, suggestions for improvement, potential errors and omissions. They are the result of creating an object-oriented model of the structure and information of the BABOK. This model captures 461 pages of the BABOK - from the Business Analysis Key Concepts chapter through to the end of the Techniques To Tasks Mapping chapter.

An agile organization is characterized by having a comprehensive portfolio of optimized business process and business capability maps grouped by their role in value creation for the customers and support of the business strategy.  These maps are linked to all the other disciplines such as finance, governance, resource management, talent management, and customer experience.   Thus, Corporate IP can be securely delivered to the point of need. 

I spent a lot of time in the past half-century doing software work: requirements, design, user experience, programming, testing, project management, writing documentation, process improvement leadership, writing 7 books and many articles, consulting, and training. Sure, there were some side trips along the way,.... But basically I’m a software guy. Over all that time, I’ve accumulated numerous insights about the software business. Here I offer 66 of those lessons. Perhaps you’ll find them as helpful as I have.

As much as we like to think we are now in a dynamic and agile world, most delivery initiatives are still some shades of agile and all shades of waterfall. These initiatives could have adopted an agile outlook and naming convention, but the businesses they support are often still predominantly waterfall – going from one clearly defined task to another until realizing value. Think for example, order to cash, just in time logistics etc.

The transition from Waterfall to Agile is never easy – especially for a business analyst who must go through this journey. This document has come about because of this challenge and as an attempt to present a practical guide of how to effectively transition over as a business analyst, and where are these worlds connected. I do not believe that all that we learned as business analyst in the waterfall era are completely useless. What has changed in the Agile world is how we think about analysis, how we present the requirements to our business and our development and testing teams. It is by no means a comprehensive and one size fits all document. But it does provide a start and a guide for those who sometimes cannot make the connection.

Using one fictitious  ‘User Story’ in the Agile section of this document, I provide concrete examples of how and when to present just enough information, while giving your audience sufficient understanding of what they need to bring the requirements to life.

John Seddon launches an attack on the value of Agile as practiced and charts a better way to analyse and design for improvement, making information technology the last thing to be concerned with, not the first.

As the business analyst (BA) role continues to evolve, the responsibilities continue to expand. One of the best ways for a business analyst to add value to a project is to understand the processes involved in both the project life cycle (PLC) and the software development life cycle (SDLC). Contrary to popular belief, the two life cycles are independent of one another, however, it's best that they are aligned.

The fact that software projects and tasks are reported to be “90 percent done” for a long time has become something of an industry joke. (A related joke states that the first half of a software project consumes the first 90 percent of the resources, and the second half consumes the other 90 percent of the resources.) This well-intentioned but misleading status tracking makes it difficult to judge when a body of work will truly be completed so you can ship the next product release to your customers. Here are several typical causes of “90 percent done” syndrome and a few possible cures.

In recent years, agile software development has been the classic example of this pursuit of magic solutions, so I’ll use that as an example here. Over the years, though, people have leapt onto the bandwagons of numerous new software approaches. They all have merits, they all have limitations, and they all need to be applied to appropriate problems.

Chaos! Stress! Everyday mess! Isn’t this an everyday situation for a business analyst? If not, either you’ve job satisfaction or you’re not being introduced to the real world of business analysis.

A person might possess great skills, however, (s)he might not be able to utilize skills without the right mix of tools and environment. A toolbox enables a person to implement the skills in the most efficient way. Possessing necessary tools is just the one part of it. Another is the knowledge to utilize the right tools at the right time to cater the solution and ensure timely committed delivery.

What are these tools? How do we map the usage of tools to the given circumstance? How can we efficiently utilize the tool? Does it depend on the solution or the approach?

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...
