Jenna's team is creating a new product. A deliverable for the project consists of building a website for the product. Jenna announces that she will be outsourcing this deliverable. Company A estimated a cost of $60,000 with completion in 3 months, Company B estimated a cost of
$100,000 with completion in 2 months, and Company C estimated a cost of $50,000 with completion in 4 months. Jenna averages the three proposed costs and determines that she will need to put $70,000 into the project budget for the website deliverable. What cost estimating technique did Jenna use?
