All too often, a senior manager will get a

The platform should be the last thing determined; NOT the first.
RULE 1: Determine the application need
RULE 2: Keep the data as close to the application as possible
RULE 3: Determine Network/Security needs
RULE 4: Decide platform
We can discuss about the rules, their content and order - but this is
*theory*.
A practise looks different:
a) if you're not mainframer then you're "open for any solution". That
means "Anything. Vritually anything except the mainframe"
b) if you're mainframer, then you are fat, old and you still repeat
"Only mainframe, no doubt. This is the only platform which... (place any
platform-specific feature like VSAM or APF or PDS)". You can even
justify and recommend MVS as system for secretary ...but no one wants to
hear you.

But seriously:
- IMHO usually the is no need to write application from scratch.
- Since you buy existing application, decision about platform is already
taken by its designers. Good platform can be advantage, sometimes is the
only way to assure RAS + S (scalability) - but not always. YMMV.
