Thanks much Duyet.. Really appreciate your ur suggestions and for your valuable time. WRT your suggestion I tried modifying your logic to accommodate further new entries into the log file. New values 'DEV' and 'QA' have been added along with the JIRA, like below:

Below is the modified section in the code: 
   my $program = $hash->{Program} || '';
        my $jira    = $hash->{JIRA}    || '';
        my $qa    = $hash->{QA}    || '';
        my $dev    = $hash->{DEV}    || '';
        if ( $program && $jira ) 
        {
            push @{ $data->{ $program }{ $jira }}, $hash;
            $hash = {};
        }
        elsif ( $program && $qa) 
        {
            push @{ $data->{ $program }{ $qa}}, $hash;
            $hash = {};
        }
        elsif ( $program && $dev) 
        {
            push @{ $data->{ $program }{ $dev}}, $hash;
            $hash = {};
        }
    }
    else
