Scrum has emerged as the default way for organisations to become more Agile. Scrum contains specific rules that, when used correctly, i.e. with the Agile values and principles in mind, can enable greater Agility. Scrum is not the only way to be Agile, and Scrum does not guarantee Agility.
The best definition of Agile is that it is about responding to change whilst managing risk. Those seeking to become Agile want to embrace change and make it an advantage whilst balancing the risk that this brings in a way that is safe enough in their current environment. So, there is not a one-size-fits-all way to be Agile. It depends on your desire for change and your risk tolerance. A small startup will naturally be more Agile than a large, hundred-year-old Bank. Frameworks such as Scrum can help people find their path to Agility.
