of the hardest challenges in 51 deployments were invisible costs: change management, data quality and process redesign, not the technology.

Same models, same use cases, outcomes measured in weeks at one company and years at another. The difference was never the AI. It was the organisation.
Budget for a failed first attempt. 61% of the successful projects followed at least one earlier failure whose cost never appears in the final return. First attempts failed when AI was applied to broken workflows, or led by technical teams without business ownership.
Sponsorship is a verb. Effective sponsors cleared blockers weekly, bridged business and technical teams and tied adoption to corporate objectives. The seven organisation-wide transformations in the sample all reached that level of integration; approving a budget was not enough.
Resistance comes from staff functions first. Legal, HR, risk and compliance were the most frequent source of resistance, in 35% of cases, ahead of end users at 23%. Mandates tied to objectives moved them; persuasion did not.
Autonomy paid where errors were recoverable. Escalation models, where AI handles 80% or more of the work and humans review exceptions, showed 71% median productivity gains against 30% where every output needed approval. The authors note the tasks differed, and that regulated decisions need review by design.
The model is usually a commodity. In 42% of implementations model choice was fully interchangeable; the durable advantage sat in the orchestration layer, the data and the process. Messy data was rarely a blocker: language models unlocked previously unusable data in 88% of cases.
Why projects failed before they succeeded, share of cases
- 35%The organisation was not ready to adopt
- 27%Critical knowledge was never captured or stored
- 18%Legal or compliance blocked the project
- 16%Technology broke or was not mature enough
- 14%Wrong problem chosen or expectations unrealistic
- 12%Talent or sponsorship gap
The Kilwa read
For a board or investment committee in Lagos, Nairobi or Cairo this is a budgeting fact, not a caution: the second attempt is the one that works, and the money goes to process documentation, data access and change management before it goes to models. Kilwa's engagements start there, with the decision the intelligence will change, who owns it and what data exists. The platform is built on the same premise: any single model is replaceable, and the provenance-flagged data layer is the asset.
