Hi Syed,
Your answer is correct by 25 %.There are so many
factors we need to consolidate when a performance problem
occurs.

There are several types of performance issue...it may be
overall system performance / performance issue with a
program of transaction.

Performance issue with a program of a t-code:

1)First find out it is user developed transaction/Program (Y
or Z programs) or SAP parent program.
2)We need to find out how much of data the job/t-code trying
to process and ammount of time taken in previous for the
same amount of data.
3)Find out is there are any changes in the program recently
(find out the recent transports moved for this progam recently)
4)Best point to start with performance issue is trace in st12.
5) if this is a problem with application programming need to
consult developer if this is because of exclusive sql
statement need to correct this with help of DBA (like
creating new index/Table partitioning)

over all system performance :

This is also we can not say it is completely because of
resource bottle neck.But some times it may be.Here also
starting point is to get info this is happening in a
particular time/ or all the day.if it is happening at a
articular time try to analyze what are the actions users
doing in that particular time.and many more things we need
analyze.I think we will not describe total resolution
here.But these are some thing we can analyze to fix issue.if
we are not able to find any thing we can open a message to
SAP.But most of the cases we can fix it with deep
analysis.And please keep in mind SAP will not suppor use
developed programs (y or Z ) :-)
