A new project is being thought of (or even an extension of the current product). As an example, say you want to build a new shopping cart application for your website. In order to get started, besides knowing exactly what you want to build (the product details), you also need to start estimating how many […]
An example of unrealistic expectations in the service industry
Filed Under Problems, Resources, Issues, Model, Development | Posted on July 29, 2008
This is a true example from around 6 years back when I was working for an IT software solutions provider (the firm did software projects for different customers). This was a decent sized company that had something like 12000 people on the rolls, doing everything from development to testing to requirements analysis, and so on. […]
Common branching strategies
Filed Under Techniques, Model, Process, Development, Software | Posted on December 29, 2007
The right branching strategy makes it easier to deliver the right code, re-create past releases, and if necessary, roll back to a previous release. Adopting the right SCM branching model facilitates rapid development, increases overall product quality and process efficiency, reduces the incidence of software failures, and improves organizational performance.
Selecting the appropriate branching model lets […]

The development methodology known as ‘Extreme Programming’ has 12 ‘Core Practices’. These can be grouped together into some groups:
Fine scale feedback
* Test driven development: Top XP teams practice “test-driven development”, working in very short cycles of adding a test, then making it work. Almost effortlessly, teams produce code with nearly 100 percent test coverage, which […]
