Looking For A More Optimized Code

is there a better code for this..?

SELECT phase, stat, subject, CASE WHEN phase = 'Initial/Data Collection' THEN '1'
WHEN phase = 'Screening' THEN '2'
WHEN phase = 'Assessment and Selection' THEN '3'
WHEN phase = 'Placement' THEN 4 END AS PhaseSort

FROM (SELECT subject, stat, CASE WHEN stat = 'Application Received' THEN 'Initial/Data Collection'
WHEN stat = 'Shortlisted' OR
stat = 'For Screening' THEN 'Screening'
WHEN stat = 'For Assessment' OR
stat = 'Passed Initial Evaluation' OR
stat = 'Passed Profiles Exam' OR
stat = 'Passed Technical Exam' THEN 'Assessment and Selection'
WHEN stat = 'For Placement' THEN 'Placement' END AS phase

FROM (SELECT subject, CASE WHEN subject = 'Process Application' OR
subject = 'Application Received' THEN 'Application Received'
WHEN subject = 'Screen Application' THEN 'For Screening'
WHEN subject = 'Phone interview' THEN 'Shortlisted'
WHEN subject = 'Initial Interview' THEN 'For Assessment'
WHEN subject = 'Profiles assessment'THEN 'Passed Initial Evaluation'
WHEN subject = 'Technical Exam and Interview' THEN 'Passed Profiles exam'
WHEN subject = 'background and reference check' THEN 'Passed Technical Exam'
WHEN subject = 'Job Offer' OR
subject = 'Contract Signing' THEN 'For Placement' END AS stat

FROM dbo.filteredtask
WHERE (subject = 'application received') OR
(subject = 'process application') OR
(subject = 'screen application') OR
(subject = 'initial interview') OR
(subject = 'profiles assessment') OR
(subject = 'technical exam and interview') OR
subject = 'background and reference check' OR
subject = 'phone interview' OR
subject = 'shortlisted' OR
subject = 'For Placement' OR
subject = 'job offer' OR
subject = 'contract signing') Phases) stats
ORDER BY phasesort
