As per my understaing Demand management is fine tuning of JCL jobs,COBOL programs and DB2 queries, by which we can save Mainframe CPU time which in turn will save cost for the clients/company.
Fine tuning of JCL jobs or programs can be identified using Strobe analysis tool which will give a detailed report of which step is taking more time and in that step which functionality or DB2 query is expensive. Based on this report in hand we can start analysing and tweak the area which is more expensive.
Hope this helps. |

| In Economics Demand Management is the art or science of controlling economic demand to avoid a recession |
from a change management point of view
we might consider ( rough approach ) these groups
change because error/malfunction
... must be done as quick as possible
change because of legal, statutory, organization modifications
... must be done according to a well defined plan
change on demand
must be done.....
NOOO
should be analyzed for the ROI( return of investment), feasibility, ...
add as many criteria You wish
all to avoid useless "change on demand" modifications |

As per my information,Demand management is related to reengineering.
In this concept Business always wants improvement in JCL,COBOL programs to consume CPU time during execution.
This is type of improvement in every aspect in Mainframe applications. |
