Time to First Prompt
Definition
Measures the elapsed engineering calendar time it takes to ready a service for first use. Or time to get from POC/Experiment into production use. Mature AI patterns and tooling automations help engineers deliver more features faster, this KPI provides awareness of how fast your engineers can take ideas and user stories and turn them into production deliverables. Highlights the tradeoffs of using different methods of developing the service with accurate (quality) or less expensive (cost). Example: If an AI initiative starts on January 1, 2024, and the model is successfully deployed on April 1, 2024, the Time to First Prompt is: April 1, 2024−January 1, 2024=3 months
Formula, as published
Time to First Prompt = Deployment Date - Start Date of Initiative Development
