Final answer:
A lack of mission, vision, and values can result in confusion, inefficiency, lack of consistency, and difficulty in attracting talent.
Step-by-step explanation:
A lack of mission, vision, and values can have negative effects on the practice in several ways. Firstly, when there is no clear mission, vision, or values, the practice may lack a sense of direction or purpose. This can lead to confusion and inefficiency, as employees may not know what goals they should be working towards. Secondly, without clear values, there may be a lack of consistency in decision-making and behavior within the practice. This can lead to a breakdown in trust and unity among the team. Finally, without a strong mission, vision, and values, it becomes difficult to attract and retain top talent who are aligned with the organization's goals and values.
