Agile is a mindset for effectively completing projects using an iterative and incremental approach. It is becoming more commonly used as traditional project management approaches are often too heavy and bureaucratic, making it difficult for organizations to remain competitive. Agile methods like Scrum, XP, and Crystal break large projects into smaller iterative cycles, accommodate frequent changes, improve return on investment, and involve customers for higher quality outputs. While only taking a few hours to learn the basics, Agile is a lifetime framework to master, with an emphasis on adaptive planning, empirical learning, and frequent inspection and adaptation of processes.
