select success.Class,
ontime.[1] as [Q1Ontime],
late.[1]   as [Q1Late],
Success.[1]as [Q1Success],
ontime.[2] as [Q2Ontime],
late.[2]   as [Q2Late],
Success.[2]as [Q1Success],
ontime.[3] as [Q3Ontime],
late.[3]   as [Q3Late],
Success.[3]as [Q1Success],
ontime.[4] as [Q4Ontime],
late.[4]   as [Q4Late]
Success.[4]as [Q1Success],
from
(
SELECT [Dept] as Class,
[1],[2],[3],[4]
FROM
(
SELECT [Dept]
      ,[Q]
      ,sum([Late]) Late
FROM lm.dbo.[allb]
WHERE  Inceptyear = 2012
  GROUP BY [Dept],[Q]
  ) a
  pivot
  (
  sum(late) 
  FOR Q IN ( [1],[2],[3],[4]) 
  ) AS PivotTable
  ) late
 inner join
  (
