We get it… you don’t need another hype piece—you need straight answers.
This Q&A brings together the top questions CIOs ask us about AI services across industries and geographies. Each answer starts “short and sweet” so busy leaders can skim for the essentials, then dives into the practical details—what works now, what to watch, and where the risks live. If you’re assessing enterprise AI services, use this to align stakeholders, shortlist use cases, and move faster with confidence.
1. What business outcomes can AI/LLM services realistically deliver in 6–12 months?
Short answer: The fastest wins come from workflow rewiring and targeted use cases (support deflection, content ops, developer productivity). Organizations that redesign processes around AI report earlier EBIT impact than those who just “add a chatbot.”
- Focus on a few measurable workstreams (ticket resolution, claims intake, KCS content, test automation).
- Pair AI with change management (policy, training, incentives) and track the business outcomes of AI
Hexaware proof: GenAI for Enterprise IT improved agility and value realization for a life sciences tech leader via a top-down use-case program. Read the case study.
2. How do we prioritize use cases with the highest near-term ROI?
Short answer: Rank by business friction (volume × cost × latency), data readiness, and feasibility (policy, security, model fit). Pilot where outcomes can be verified in weeks.
- Score each idea on value, risk, and dependency on scarce SMEs; document each AI use case
Hexaware proof: A fintech cut SME dependency during an IT transition using Hexaware’s GenAI platform, accelerating timelines. Read the case study.
3. Which enterprise functions see the strongest lift today?
Short answer: Customer operations, marketing/content ops, software engineering, and knowledge-heavy back-office functions lead current investment and returns with generative AI.
- High-volume text tasks + clear ground truth = faster payback.
Hexaware proof: GenAI-powered product descriptions improved relevance and readability for a furniture retailer. Read the case study.
4. When should we use classical ML vs. generative AI (or combine them)?
Short answer: Use classical ML for prediction/forecasting on structured data; use GenAI for language, images, and code. Combine them for “predict → explain/generate” flows (e.g., predict churn, then generate outreach).
- Start with ML where labeled data and KPIs are mature; layer GenAI to automate knowledge work around the prediction.
5. Build on open models, buy a platform, or use managed APIs—what’s the real TCO?
Short answer: APIs speed time-to-value; platforms add governance and integration; open models reduce per-token costs at scale but raise MLOps/security workload. Decide by data sensitivity, latency/SLA, and scale.
- Consider exit plans, data residency, and compliance (ISO/IEC 42001, SOC 2).
Hexaware proof: SAP SuccessFactors migrations with Amaze® for ERP reduced risk and accelerated delivery for regulated clients. Read the case study.
6. What timeline should we expect for POC → pilot → scale?
Short answer: A focused POC can be 3–8 weeks; a controlled pilot 8–12 weeks; scale depends on integration, governance, and org change. Use stage gates tied to eval metrics.
- Avoid “perpetual pilots” by pre-agreeing on success thresholds and production checklists; treat this as an AI implementation roadmap.
7. LLM vs. RAG vs. Vector DB: which approach fits our needs?
Short answer:
- LLM gives quick, general answers; use for prototyping and non-sensitive tasks.
- RAG grounds an LLM in your latest content with citations; use when facts change often.
- Vector DB powers semantic retrieval for RAG; use when you need scalable, permission-aware search across sources.
Hexaware proof: Our Agentic AI for post-funding mortgage loan reviews—an LLM-orchestrated workflow where pairing the model with governed retrieval and a vector index is ideal—improved audit quality and responsiveness. Read the case study.
8. How do we select models, deploy (cloud vs. on-prem), and handle data residency?
Short answer: Choose models by task quality, cost, latency, safety, and deployment constraints (private networking, VPC). For data residency/compliance, align provider regions and controls to your regulatory scope.
- Document data flows (PII, PHI), retention, and redaction.
Hexaware proof: Azure-based transformations show how cloud controls and automation reduce cost while increasing agility. Read the case study.
9. How do we protect sensitive data and prevent IP leakage with LLMs?
Short answer: Enforce least-privilege access, encryption, redaction, secure prompt patterns, and output validation. Bake in threat models from the OWASP LLM Top 10.
- Use private endpoints, content filters, and evals for data exfiltration risks.
Hexaware proof: Tensai® AIOps emphasizes governed automation across Digital ITOps. Read the case study.
10. What contracts, controls, and audits should we require from AI vendors?
Short answer: Ask for DPAs, audit reports (e.g., SOC 2), ISO certifications (27001; 42001 for AI MS), security architecture, data-handling/retention, red-team results, and exit strategies.
- Map obligations to NIST AI RMF and your internal control catalog.
11. What’s “minimum viable” responsible AI for launch?
Short answer: Policies + human-in-the-loop + evaluations tied to harm scenarios (toxicity, bias, privacy, hallucinations) aligned to NIST AI RMF and the GenAI Profile.
- Maintain incident playbooks; log prompts/outputs with guardrails; make responsible AI a living program, not a checkbox.
12. Which regulations should we plan for early?
Short answer: Plan for sector/privacy rules now and EU AI Act timelines (key obligations begin 2025–2026). Coordinate compliance, legal, and security early.
- Track model transparency, copyright, and post-market monitoring requirements.
13. How do we measure and reduce hallucinations—and prove accuracy?
Short answer: Define task-level evals (precision/recall, factuality, citation coverage), add retrieval confidence and guardrails, and run regression tests on each release. Use eval pipelines continuously.
- Improve with better retrieval, re-ranking, and fine-tuning.
14. Which KPIs matter for executives?
Short answer: Tie to business outcomes: cost per resolution, cycle time, backlog burn-down, CSAT/NPS, developer velocity, and ultimately EBIT impact.
15. What skills and change-management drive adoption?
Short answer: Upskill in prompt design, RAG patterns, data governance, and AI safety. Adoption accelerates with playbooks, “golden paths,” and champions; treat AI as a workflow change, not a tool drop.
16. How do we set up a GenAI Center of Excellence and operating model?
Short answer: Create a cross-functional CoE (product, data, security, legal, risk, change) owning standards, evals, and reference architectures. Fund platform capabilities used by many teams.
17. What proof should we demand from vendors (beyond demos)?
Short answer: Scenario-based evals, red-team artifacts, latency/throughput SLAs, retrieval accuracy metrics, and runbooks for failure modes; plus references in your industry.
- Ask to test on your data, not theirs.
18. Which questions separate credible vendors from hype?
Short answer: “Show data lineage and residency,” “Prove guardrails against prompt injection,” “What’s your fallback if retrieval fails?” “How do we exit without lock-in?”
19. What next? (Bonus Question)
If these answers helped you frame the conversation, the next step is to see how they translate into your context—your data, your controls, your KPIs. Our teams stand up focused pilots, build the right guardrails, and scale what proves value.
