Programming effort implies availability of the source code. Not necessarilly. We could re-write from scratch.

Imeasurable. Not at all. (Okay I used a weasle word). >> Because of that, my management wants a justification to re-do this one. Define "justification". A business case. It costs us this much in: Hardware (I don't know this one without the answer to my question) Software (I know what the canned package costs) Productivity (Nebulous, at best) Other factors. It will cost us this much in: Programming Testing Deployment Disk Other factors Subtract a from b.

I asked for a reasonable estimate, so that I could take my recommend solution back to management. I want the file moved to CMDT, but management is expecting 'completed staff work'. - -teD O-KAY!
