IBM publishes a Forrester TEI result claiming high ROI and productivity gains (IBM references a published high ROI in some marketing materials; a TEI PDF cited by IBM shows a different, somewhat higher ROI in the executive summary—this discrepancy suggests buyers should request the exact study version and methodology).
- IBM marketing page references a Forrester impact study and cites “published high ROI” and “a substantial increase in productivity.”

- Official vendor product and marketing pages
- Commissioned Forrester TEI PDF (vendor-cited)
TEI PDF (commissioned study) reports very high ROI, substantial net present value, large present-value benefits, and a payback measured in a small number of months. It includes a quote: “We have so many business units dependent on the platform that they can’t function without it.”

**Critical evaluation (methodology / independence):**
- TEI studies are typically commissioned by the vendor and model a “composite organization.” They are useful for understanding possible benefit categories but are not independently audited ROI results.
- Buyers should request additional information on:
- the number and profile of interviewees,
- baseline assumptions,
- sensitivity analysis,
- which costs were excluded (e.g., internal platform teams, OpenShift operations, partner services).
