\fCreate and post a work breakdown structure (WBS) for a project to introduce self-checkout registers at the NLU Chicago campus bookstore (use your imagination). Provide the top two levels of the WBS. Decompose ONE of the second level items to the third level. Use whatever tool or format you want. For best results, attach the WBS to your post as a file. Be sure the children items under a parent item define 100% of the scope of the parent. There is no single right answer. Your score will be based mostly on effort
