Iterative Waterfall

A waterfall model comprises of a sequence of processes, in which progress is assumed to be flowing steadily downwards (like a waterfall). But a classic waterfall model is only idealistic. It assumes that no modification or defect is introduced during any of the activities. In practice, changes and defects get introduced in almost every phase of the process. And once a modification or defect is detected, we need to revisit the analysis phase and redo some of the work done in subsequent phases. Only a timely feedback from the customer and its resolution makes a waterfall model perfect.
For smaller and medium projects with a defined scope of work, we usually adopt this model.


Agile Methodology

Agile methodologies are based on iterative-incremental processes, with very short iteration cycles (weeks rather than months). A working software is released at the end of each iteration and is the principle measure of progress. Agile methodologies also emphasize close communication with the stakeholders of the project.
This methodology gives customers greater control over the final solution because they can quickly change the direction of solution development and implementation from one sprint cycle to the next. This means that they are better placed to respond to their business needs as development of the solution progresses.
Our agile processes, refined over several years of project execution, ensure customer satisfaction as their flexibility allows adjustments to meet expectations.
The features of our agile project management methodologies are:
Adaptive software development approach
Feature driven development
Extreme programming and rapid development models
Agile techniques including test driven design (TDD), agile modelling, agile change management, and database refactoring to improve productivity
Continuous delivery of useful software
Flexibility to adjust to late changes in requirements
Automated development increasing productivity and putting less strain on the quality review process
Continuous attention to technical excellence and good design
Regular adaptation to changing circumstances
