Certificate in Business Data Analytics (CBDA) — Question 8

The outcome from an analytics initiative has resulted in key stakeholders wanting to move forward with a project to redesign the company’s website. The business analyst has called a meeting to work on drafting a plan to assess the level of effort required to complete this work. Many of the invited participants redesigned the website before and were invited so they could provide estimates using their knowledge and experience from the past.
The business analyst is using which method to estimate this work?

Answer options
