Which is typically the first stage in the AI lifecycle?

• A. Deployment
• B. Monitoring
• C. Retirement
• D. Problem definition

Answer: (D)

Defining the problem and setting clear objectives is the starting point because everything that follows hinges on understanding what you’re trying to achieve, how you’ll know you’re successful, and what constraints you must respect. In this initial stage you articulate the business goal, identify stakeholders, determine available data and data quality, assess feasibility, and establish measurable success criteria and governance boundaries. This foundation guides data collection, model selection, evaluation methods, risk controls, and the deployment plan, ensuring the effort actually solves the right problem and complies with rules and expectations. After this comes designing and building the solution, deploying it, monitoring its performance in production, and eventually retiring or updating it as needed.
