Lance, after years as a successful engineering career, has decided to pursue hislifelong dream of opening a photography business. Lance has been dabbling inphotography for a number of years and has become quite the master. Hisprimary products include pictures of the Australian outback. Lance has beenselling his products at local markets, arts and craft fairs, and at local businesses.Business has been picking up significantly and Lance feels that now is the time tolaunch a website for his business. Lance wants a website that will showcase hisproducts, allow secure online ordering, and has social media capability. Inaddition, Lance would like to provide videos on the process of taking amazingphotos. The videos will be free for a two week period and then there will be anominal monthly subscription fee. This monthly fee will allow one to watchunlimited videos and download samples of his work. Lance wants to add enoughvideos to get the subscription service started and then he will add additional newvideos each month.He contacts Leigh, a family friend, who owns a software and websitedevelopment business. They meet for lunch and Lance gives her all the specificrequirements for the website. Lance would like to have a website launched inless than three weeks. He will be a vendor at a large art show in six weeks andwants a website in place so potential visitors can peruse his products prior to theshow. Leigh is happy to help Lance with the website and carefully takes notes ofall his website requirements. She tells Lance that she needs to estimate how longthe website project will take given that she and her employees are in the midst ofseveral projects. However, she promises that she will try her best to have theproject completed within three weeks. Lance tells Leigh that he is willing to payextra in order to have the website completed within a three week period.Leigh goes back to her office and puts together the project activities, the time tocomplete each activity, and whether an activity time can be reduced (crashed) byhiring additional workers. She does not want to begin shooting videos for thesubscription service (Activity J) until the videos for photography are complete(Activity B). Table 1 provides the activity, description, time to complete anactivity, predecessors, and the maximum amount that an activity can be crashed(completion time reduced). Leigh needs your help. Her project managementexpert is on vacation this week.
