Good morning:

 We filled out the sizing document twice based upon different information
provided by SSA and get very different results in terms of system sizing.
Being that we do not use BPCS yet the information on the sizing document can
be understood differently and the issue of wanting to go to release 8.x in
which there is very little information. The difference is systems is over 1
million so we would like to get it closer than that.

 What release are you on?

 How many users do you have ?

 What size system do you have ?

 Please advise

Once upon a time (earlier versions of BPCS) SSA GT had what was known as a 
Sizing Questionairre.  Filling it out can be a pain.

Into it you put statistics like the size of your business
(how many transactions a day of various kinds)
(how many years you need to store history of transactions)
(how many invoices, average lines on invoices)
(how many customers ... various metrics)
what BPCS applications will you be running
how many different languages needed - do that on partitions by country or 
what - because that can mean multiple copies of OS/400 and BPCS software
how many different environments needed, because there may be tailoring 
needed differently for different divisions of the company
average number of concurrent sessions per user
how fast you want your performance
(subsecond response)
what IBM features you need to be using
what other stuff you want on your system OTHER than or in addition to BPCS

Then from the results of the Questionnairre, SSA and GT and any number of 
intermediate consultants could tell you how fast a processor you needed on 
what model 400.
