NTTコムウェア's 30% AI-run ops unit bans パワポ文書

NTTコムウェア's 30% AI-run ops unit bans パワポ文書

3 Key Points

  1. What happened

    NTTコムウェア's platform services team already delegates about 30% of its IT operations to AI agents, aiming for 70%. In July 2024 it required members to write reports as text only, banning パワポ文書.

  2. Why it matters

    Kurama says slide decks carry meaning in layout, diagrams and context that AI cannot read, so RAG training on them failed to deliver expected answer quality. Team members' writing skills clearly improved, he says.

  3. What to watch

    Success hinges on defining the business scenario — why and what output — before deploying AI, and on giving AI complete, systematic terminology, which Kurama calls an ontology. The 70% target is the number to track.

WHO IT HITSIT operations and SRE teams at large enterprises that feed internal documents into AI assistants are the most directly affected, since it is those teams that must decide whether slide-based reports are usable training data. Internal communications and documentation staff who write reports may also need to switch formats.

Context & Analysis

The platform services team did not move to AI first and then fix its documents. According to Kurama, the team had long answered internal inquiries by asking people who already knew the answer, and it struggled with the state of its internal data before deploying AI agents. Its work spans AIOps, SRE, front-end and back-end development, and security operations, so the documents feeding those workflows were diverse and often not in AI-ready form. The team first ran RAG training on internal documents, but the results fell short of expectations.

Kurama points to three causes for that shortfall. One is that reporting formats themselves were not standardized, with files named with versions like 0.6 or 0.7 and copies scattered around, leaving AI unable to tell which data to reference. Another is that people could not frame the right questions. The パワポ文書 problem sat alongside these: slides read well to humans who filled in the gaps, but they carry no tags, so AI cannot follow them. Kurama also notes two broader shifts — falling human writing ability and advancing terminology technology — that appear to be driving demand for the text-only rule. He cites Amazon's practice of running decision meetings on Microsoft Word alone as a known reference point, because it forces participants to state the point, the issues, and who decides.

For readers, the stakes are less about the format rule itself and more about sequencing. Kurama argues that without a clear business scenario, AI adoption becomes a string of costly "token-wasting" experiments, and that companies should define purpose and outcome before deciding what AI should handle. Whether the team reaches its 70% goal may depend less on model capability than on whether it can standardize its documents and terminology enough for AI to use them.

FAQ
When did NTTコムウェア start using AI for this work?
The platform services team began working on AI use in July 2024, the same month it switched members to text-only reporting rules.
Does the パワポ文書 ban mean employees cannot use Microsoft PowerPoint?
It does not ban creating documents in Microsoft PowerPoint. It requires that reports be written in text only.
Why were slide-based reports a problem for AI?
Kurama says slide decks omit the logic and context, placing meaning in layout and images. AI then cannot read the creator's intent, which hurt answer quality.
