The situational leadership model divides the growth process of employees in a specific job into four stages: the first stage is R 1 "No Ability, No Willingness and No Anxiety", the second stage is R2 "No Ability, No Willingness and No Confidence", the third stage is R3 "No Ability, No Willingness and No Anxiety" and the fourth stage is R4 "No Ability, Willingness and No Anxiety". Compared with the four different stages of employees, leaders should also adopt four different leadership styles. When employees are in the first stage of R 1, leaders should guide and guide employees by "informing"; When employees are in the second stage R2, leaders should explain their work and convince employees by "selling". When employees are in the third stage R3, leaders should take the way of "participation" to motivate employees and help them solve problems; If the employee reaches the fourth stage R4, the leader should hand over the work to the employee by means of "authorization", and the leader only needs to supervise and inspect the work. Leaders adopt work behavior and relationship behavior. According to the level of work and relationship behavior, four leadership styles are adopted at different stages, namely S 1, S2, S3 and S4. For different stages (readiness) R, adopt corresponding leadership style S. Through behavior research and practice, it is most likely to effectively develop employees and improve team performance. When we use the situational leadership model, the first step is to determine the work, blame or activity that needs to be performed; The second step, leaders (such as employees) evaluate the preparation (stage) of the work; The third step is to choose the appropriate leadership behavior according to the needs of the leader's readiness.
