こんな感じのクラスをリファクタリングには？

EmployeeBean.java

public class EmployeeBean {

    private boolean forManagementMode;

    public String getFullName(String userCode) {
        Employee employee = findBy(userCode);

        if (employee.middleName == null) {
            return employee.lastName + " " + employee.firstName;
        }
        return employee.lastName + " " + employee.middleName + " " + employee.firstName;
    }

    private Employee findBy(String userCode) {
        User user = findUserBy(userCode);
        if (user == null) throw new IllegalArgumentException("user not found.");

        Employee employee = Employee.findBy(user.userId);
        if (employee == null) throw  new IllegalArgumentException("employee not found.");
        return employee;
    }

    private User findUserBy(String userCode) {
        User user = User.findBy(userCode);

        if (user == null) throw new IllegalArgumentException("user not found.");
        if (isForManagementMode()) {
            if (user.activateDate == null) return null;
            if (user.activateDate.compareTo(new Date()) < 0) return null;
        }

        return user;
    }

    public boolean isForManagementMode() {
        return forManagementMode;
    }

    public void setForManagementMode(boolean forManagementMode) {
        this.forManagementMode = forManagementMode;
    }

}
