Please answer Hardrock part and explain:

At the Hard Rock Cafe, like many organizations, project management is a key planning tool. With Hard Rock's constant growth in hotels and cafes, remodeling of existing cafes, scheduling for Hard Rock Live concert and event venues, and planning the annual Rockfest, managers rely on project management techniques and software to maintain schedule and budget performance. 'Without Microsoft Project," says Hard Rock Vice-President Chris Tomasso, "there is no way to keep so many people on the same page." Tomasso is in charge of the Rockfest event, which is attended by well over 100,000 enthusiastic fans. The challenge is pulling it off within a tight 9-month planning horizon. As the event approaches, Tomasso devotes greater energy to its activities. For the first 3 months, Tomasso updates his Microsoft Project charts monthly. Then at the 6-month mark, he updates his progress weekly. At the 9-month mark, he checks and corrects his schedule twice a week. Early in the project management process, Tomasso identifies 10 major tasks (called level-2 activities in a work breakdown structure, or WBS): talent booking, ticketing, marketing/PR, online promotion, television, show production, travel, sponsorships, operations, and merchandising. Using a WBS, each of these is further divided into a series of subtasks. Table 3.8identifies 26 of the major activities and subactivities, their immediate predecessors, and 102 time estimates. Tomasso enters all these into the Microsoft Project software.# Tomasso alters the Microsoft Project document and the time line as the project progresses. "It's okay to change it as long as you keep on track," he states.Table 3.8 Some of the Major Activities and Subactivities in the Rockfest Plan ACTIVITY DESCRIPTION PREDECESSOR(S) TIME (WEEKS) Finalize site and building contracts 7 B Select local promoter A 3 h N C Hire production manager A 3 D Design promotional Web site B 5 E Set TV deal D 6 Hire director m 4 G Plan for TV camera placement N H Target headline entertainers 4 1 Target support enterta H 4 C Travel accommodations for talent 10 K Set venue capacity C N 12 L Ticketmaster contract D .
