Three AI implementation mistakes I keep seeing in 2026

TODO: scrape Durable blog post content. Placeholder body below.

Every other Nexera intake call sounds the same in week two: the client tried something with another vendor, it did not stick, and now they want to know what we will do differently.

Here are the three mistakes I see most.

1. Buying a model when the workflow needed a tool

Models are a building material. Tools are what an operator opens at 9am. The mistake is buying access to a model and assuming the team will write their own prompts on top of it. They will not. They will use it twice and forget.

2. Shipping the demo, not the integration

A polished demo on a vendor laptop is not a Tuesday-morning workflow. The integration that pipes outputs back into the CRM, the calendar, the inbox - that is where the value lives, and that is the part that gets cut for time.

3. Designing in a vacuum

If the AI engineer never sits with the operator who will use the tool, the tool will lose to the operator's existing habit. Every time. Habit beats novelty by week six.

What we do instead

Two weeks of shadowing before any code. One scope, one quote. Daily walkthroughs. Documentation and Slack handoff at week six. None of it is novel. All of it is rare.
