Reply with quote

Hi Experts,

I have automated some tasks that people here have been doing manually with a series of sort jobs and cobol db2 programs...

I will now have to explain with NUMBERS ... as to how this will be a better alternative... $$$$ saved and Effort hours - man hours saved..


How can I for example find the cost of say:


1. Submitting a mainframe job.
2. Opening and viewing / filtering data in a VSAM file.
3. Searching data in a file et all....


Please suggest!

Cost of a mainframe job depends upon the charge back method used and could range from 0 for a site that does not charge costs back to something larger than zero. What you want to know is EXTREMELY site dependent and hence any comments you get on a public forum like this should be considered as no more than guidelines, at best.

If your site uses an SMF analysis tool such as MXG, you can find the resources used for different tasks from that tool. However, it is a HUGE leap from resource usage to cost.

Hello,

Quote:
$$$$ saved and Effort hours - man hours saved..

The above line seems like a non technical requirement.
If you have automated some manual task and reduced manual effort then you could use a hypothetical formula something like,

Amount saved = the time taken to perform the task manually(in hours) * number of times performed * amount billed/person for 1 hour.

If you want to quantify your automation which reduces manual effort then, MHO is to have a presentation that says something like "2 man hours saved per day as a result of automation".

If you want the calculate the cost of running a mainframe job, then as Robert said it is site dependent and it may depend on several resources like CPU,DASD,TAPE,EXCP activity,time of the day when the job was run, service class etc..
