How to Address Application Security in Agile Scrum Teams?

Agile SCRUM Team Composition and Application Security

One of the concerns that takes the back burner while setting up the agile SCRUM teams is application security. One other area that gets similar behavior like security is performance which shall be addressed in later articles. However, performance gets addressed quickly as it is key quality characteristic and gets noticed by end users very quickly. In the traditional waterfall based development model, security gets fair attention as the non functional requirements related with security gets captured in the initial stages and the team gets composed of at least one security officer/specialist/architect to take care of security requirements. However, having a security specialist/officer in each SCRUM team is not feasible …

Tips for Newbies to Create Architecture Diagrams – Part 1

Wondering How to Create Architecture Diagrams

Logging Tips/Best Practices for Newbies

When starting the career of application developer in IT with one or more programming languages, one thing which is kept on back burner and kept for really long is logging. In fact, when I started my career as a programmer, when I realized that I wanted to know about what to log and what not to log, it was almost 4 years or so. This was my involvement in learning nitty-gritties of programming language itself, and not paying enough attention to logging at all. And, when I learnt most of it all, I realized how much value I added to programming by logging appropriate stuff in log files which was …

What are different types of Business Processes?

Make Business Analysts Your Friend & Deliver Great Product

In my experience, I have found application developers not very clear on roles and responsibilities of business analyst (BA) and, more importantly their need in the project. Thus, they do not pay attention to what business analysts has to say on the requirements and end up faltering on various aspects of project execution due to lack of proper understanding of the business requirements.
