Given the partial WBS tree below, create a corresponding WBS list with an

expanded numbering$\_$system. The WBS List is "partial" because there are no WP

under several of the second$-$level branches. Start numbering with:

$"1.$ Retail Web Site"

Use an expanded coding to create the WBS list, from the tree as shown; use the

presentation slides on chapter $7$ as a reference as needed. Assume the bottom levels

for "Requirements Gathering" and "Site Software Development" express a set of WP$.$
