The 4Ws problem canvas helps in identifying the key elements related to the problem. 4Ws problem canvas is a part of __________.
Problem scoping
The AI project cycle has the stages Problem Scoping, Data Acquisition, Data Exploration, Modelling and Evaluation. The first stage, problem scoping, defines exactly what problem the project should solve before any data is gathered.
The 4Ws problem canvas is the tool used in this first stage. It asks four questions: Who are the stakeholders facing the problem, What is the problem and its evidence, Where (in what context or situation) it arises, and Why solving it would be valuable. The answers are summarised in a problem statement template.
Data acquisition collects the data once the problem is defined, data modelling builds the model from that data, and evaluation tests the finished model. None of these uses the Who-What-Where-Why canvas.
Problem scoping option is correct.
