Question

The business understanding phase of CRISP-DM may include:

A. Developing a project plan or integrating the CRISP-DM plan with a high-level project plan
B. Understanding which algorithms should be applied to the problem
C. Understanding the business problem that needs to be addressed with a data mining project
D. Understanding whether it's feasible to collect the input data in an ongoing basis

Answer 1

The business understanding phase of CRISP-DM involves developing a plan, understanding the business problem, assessing data collection feasibility, defining the problem clearly, ensuring buy-in, and brainstorming solutions within project constraints.

Step-by-step explanation:

The business understanding phase of CRISP-DM is a critical initial step in the data mining process where the groundwork for the project's success is laid. This phase involves a few key activities:

• Developing a project plan or integrating the CRISP-DM plan with a high-level project plan.
• Understanding the business problem that needs to be addressed with a data mining project.
• Understanding whether it's feasible to collect the input data on an ongoing basis.

During this phase, it's essential to clearly define the problem. This involves gathering information from customers and stakeholders, finding expert information, and doing a root cause analysis to identify the real problem. Ensuring buy-in from all project collaborators is also key. Finally, it is necessary to brainstorm alternative solutions to ensure that the project's objectives can be met within the established criteria and constraints.
