A good example of a project that Best Buy created was Magnolia Home Theatre. A few years back, major retailers carried only the basics- home theatre setup with televisions on the walls and basic speakers. Now, Magnolia sells higher end televisions, speakers, and receivers. Only Magnolia certified professionals can work inside Magnolia. Best Buy had to bring all the materials and supplies to its locations while their everyday business was still operating. This presented a major challenge of scheduling and constructing with customers still shopping in the store.
Best Buy does not use Gantt charts or network diagrams; instead they use the daily business tracker and scorecards. The scorecards will tell you exactly how much you are budgeted for that day, how much you should sell in service, geek squad black tie protection plans, and accessories. With the scorecards you have to stay at a certain percentage to stay profitable which consequently affects labor and hours they give employees to work. Best Buy should consider using Gantt charts which would be less costly and can be very beneficial to all its employees and the company overall.
