You could use conditional aggregation :

SELECT ANALYST
    ,COUNT(CASE WHEN status = 'unchecked'   THEN 1 END) AS unchecked
    ,COUNT(CASE WHEN status = 'observation' THEN 1 END) AS observation
    ,COUNT(CASE WHEN status = 'supervisor'  THEN 1 END) AS supervisor
    ,COUNT(CASE WHEN status = 'pending'     THEN 1 END) AS pending
    ,COUNT(CASE WHEN status = 'closed'      THEN 1 END) AS closed
    ,COUNT(*) AS Grand_Tot
FROM tab
GROUP BY ANALYST
ORDER BY ANALYST;

---

EDIT:

Can i know how to SUM the Grand_Tot Column along with that query i was trying SUM(Grand_Tot) but getting error as invalid identifier.

One way is to use subquery:

SELECT sub.*, SUM(Grand_Tot) OVER() AS Sum_Grant_Tot
FROM (
    SELECT ANALYST
        ,COUNT(CASE WHEN status = 'unchecked'   THEN 1 END) AS unchecked
        ,COUNT(CASE WHEN status = 'observation' THEN 1 END) AS observation
        ,COUNT(CASE WHEN status = 'supervisor'  THEN 1 END) AS supervisor
        ,COUNT(CASE WHEN status = 'pending'     THEN 1 END) AS pending
        ,COUNT(CASE WHEN status = 'closed'      THEN 1 END) AS closed
        ,COUNT(*) AS Grand_Tot
    FROM tab
    GROUP BY ANALYST
) sub
ORDER BY ANALYST;
