Further Resources FAQsDefinition of AgileAgile refers to a set of principles and practices that guide teams in developing software products through incremental delivery, adaptive planning, and continual improvement. Agile emphasises iterative development, close team collaboration, and frequent customer feedback to deliver high-quality solutions quickly and efficiently.Agile methodology at a glanceAspectDescription

- Historical origins and evolution of Agile
The Agile approach originated in the late 1990s as software teams sought alternatives to rigid project management models like the Waterfall model. In 2001, seventeen thought leaders signed the Agile Manifesto, formalising Agile values and sparking the formation of the Agile Alliance. Since then, Agile has evolved beyond software development into project management, product development, and operations.
Benefits of Agile
Flexibility: Respond rapidly to changing customer needs and market conditions.Continuous improvement:
Regular retrospectives help teams adapt and improve their processes.communication toolCustomer satisfaction: to both communicate with and educate clients. The project managers can use the triangle to show the project’s constraints to the clients, visualise how changes would affect them, and set realistic expectations regarding project deliverables. Frequent delivery ensures customer requirements are met early and often.Risk reduction
Transparency:Utilising the triangle will help in
Iterative development and open communication foster stakeholder trust.managing risks
Reduced risk:. This is possible because this will help the team to predict potential problems earlier in the process, have a contingency plan, and balance the risks in all three constraints. Incremental delivery allows for earlier issue detection and correction.The use of the project management triangle allows for Enhanced team collaboration:managers Cross-functional teams communicate daily to resolve challenges efficiently. to make decisions in a balanced manner. As such, it becomes possible to deal with complex projects with great ease.Agile vs waterfall modelEnhance your skills with our expert-led courses
