To take advantage of Sub-capacity licensing and its inherent value, IBM customers are required to:
1) Install either the IBM License Metric Tool (ILMT) or BigFix Inventory (BFI).
2) Produce audit reporting on at least a quarterly basis
3) Retain such reports continuously for 2 years.
However, while IBM mandates the use of these tools for Sub-capacity license owners, it does not contractually require that they be used to their optimal capabilities. This is where many customers miss an important opportunity to start down the road toward formalized Software Asset Management.
IBM requires the use of these tools only where sub-capacity software is installed, but if the BigFix agenting is installed elsewhere, organizations can discover other non sub-capacity IBM software instances (and in the case of BigFix Inventory, over 40,000 other software titles from over 9,600 other publishers).
Like many IBM customers, the last company I worked for installed ILMT, and struggled with it initially. Early versions of the tool were hardly perfect, and this gave it a “bad rep” with the IT staff. With perseverance however, we were eventually able to stabilize the application and begin to extract some value from it in the form of software discovery reporting and the requisite audit reporting.
We quickly realized, however, that the value of software discovery data (on their own) is extremely limited. To make sense of the data that were captured, more background information was needed.
Specifically we required a complete understanding of the IBM licensing inventory we held; without which we were unable to accurately bundle products within ILMT or produce even the simplest reconciliation to our Effective License Position.
Once this was compiled however, we found that we were able to better control our software estate, and as an unforeseen secondary benefit, found ourselves well on our way down the path of Software Asset Management (all because we were using a contractually required IBM tool.)
