The reality check
Gartner's research delivers a sobering message: only 11% of leaders report GenAI met their primary business objective.
FOMO and vendor pressure often lead to misaligned investments that inflate costs (sometimes 5 to 10x budget) and dilute benefits.
The Defend, Extend, Upend framework
Gartner recommends categorising AI use cases:
Defend: Agent experience and productivity
Soft benefits: improve how your team works.
- Agent assistants.
- Call summarisation.
- Knowledge retrieval.
Extend: Cost savings and revenue
Hard benefits: measurable impact.
- Virtual customer assistants (VCAs).
- Automated quality assurance.
- Upsell prompts.
Upend: Transformation bets
Long-term strategic plays.
- AI-driven contact centres.
- Minimal human agent models.
Recommendation: prioritise Defend and Extend for near-term ROI; pursue Upend cautiously as strategic bets.
Critical success factors
Rollout strategy: target specific agent cohorts for maximum impact.
Change management: prevent productivity leakage through training, monitoring, and process redesign.
Hidden costs:
- Data quality investment.
- Scaling and inference costs.
- Vendor pricing model changes.
- Scarce GenAI talent.
Security and trust: plan for governance and guardrails from day one.
Strategic assumptions
- By 2026: 75% of GenAI adopters will see productivity gains, mostly as soft benefits.
- By 2027: 50% will redesign processes to convert those gains into measurable ROI.
The bottom line
Don't let hype dictate your GenAI investment. Let business outcomes drive it.
A metrics-driven, goal-aligned, phased approach to GenAI adoption is essential to realising ROI and avoiding costly missteps.
