The best AI feature is the one people actually use.
Start with a repeated task and a result people can recognise as useful. The technology comes after the problem.
Choose a bounded task
Look for a recurring bottleneck: finding an answer, reading a document, categorising an enquiry or preparing a first draft. Define the input and the expected output before choosing a model.
Design for verification
Show source material where the answer depends on facts. Make it easy to correct a result or escalate to a person. The interface should make limits as visible as capabilities.
Evaluate before expanding
Test representative examples, including difficult and incomplete inputs. Measure usefulness, accuracy, speed and cost. Use a small pilot to improve the workflow before giving it more responsibility.
