IBM Tech Doc # TD105503 is really quite excellent. I'd like to point out that there are other possible definitions of "lifecycle" that are situational and also quite important. Here are some notable examples:
* design resiliency * economic * security * regulatory * software/operating system currency: compatibility * software/operating system currency: exploitation * model upgrade (same serial number) * Capacity On Demand (CBU, CPE, etc.) * accounting/depreciation The last one is my least favorite, perhaps because I don't always understand it. -------------------------------------------------------------------------------------------------------- Timothy Sipples IT Architect Executive, Industry Solutions, IBM Z & LinuxONE, Multi-Geography -------------------------------------------------------------------------------------------------------- E-Mail: [email protected] ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
