Create table #SUMMARYDATA(NIP varchar(10), NAME varchar(50),DEPARTMENT varchar(90),STATUSIN datetime, STATUSOUT datetime,LATECOME TIME(0))
Insert into #SUMMARYDATA
Values('A1','ARIA','BB','2020-01-21 08:06:23','2020-01-21 11:58:36','00:06:23'),

Select s.DEPARTMENT,Q.[Month],Q.[Year], 
    Case when Max(LateCount) > 2 then 1 Else 0 End as LateCome  
from #SUMMARYDATA s 
inner join 
(
 SELECT NAME, MONTH(StatusIn) as [Month] , YEAR(StatusIn) as [Year], 
 Sum(Case when LateCome > '00:00:00' then 1 Else 0 End) as LateCount

 group by NAME,  MONTH(StatusIn), YEAR(StatusIn)
) Q 
ON MONTH(s.StatusIn) = Q.[Month] and YEAR(s.StatusIn) =Q.[Year] and s.NAME = q.NAME
group by  s.DEPARTMENT,Q.[Month],Q.[Year]

--- Or make it a bit more elegant

;With sdCTE as
(
 SELECT NAME, DEPARTMENT, MONTH(StatusIn) as [Month] , YEAR(StatusIn) as [Year],  
 Case when LateCome > '00:00:00' then 1 Else 0 End as LateCome 
 from #SUMMARYDATA
)
Select DEPARTMENT, [Month],[Year], 
    Case when Max(LateCount) > 2 then 1 Else 0 End as LateCome  
from
(
    select Name, DEPARTMENT, [Month],[Year], Sum(LateCome) LateCount  
    from sdCTE
    group by Name,DEPARTMENT, [Month],[Year]
) Q
Group by DEPARTMENT, [Month],[Year]
