A business analyst's ability to adapt to changing environments, stakeholders and work priorities is essential to performing effectively. Adaptability is the ability to change communication styles, formats, and approaches on the go in order to suit changing environments and meet demands. Adaptability requires a business analyst to be curious and interested in the needs of their stakeholders, which will enable them to adjust their interactions to suit the stakeholder's requirements. It is, therefore, an important skill for a business analyst to develop by regularly tuning into the stakeholders' preferences in terms of communication, information needs, and general style and approach. 

Let's consider a real-world scenario.

If a business analyst is employed to work in a financial institution where high-level stakeholders are involved, it would be important for them to adapt their way of communicating, their own personal style of interaction, and their general approach to be structured and follow the formal procedures and etiquette often followed within traditional financial institutions. However, should the business analyst be re-assigned to work in an agile software development environment, they must adapt. In this type of environment, the communication protocols and general work procedures are much less formal and are more fluid in nature. The business analyst should be able to adapt to suit the new environment's requirements by being less formal in their communication style, be able to follow less prescribed processes, and be flexible in the manner and approach that they follow in their work.
