Question: LO9.2Lavell started out mowing lawns in the neighborhood when he was 13 years old. He did such good work that, without advertising, his business grew steadily each year. After college, Lavell decided to continue the business as a full-time career. One of his concerns, however, is the number of hours he is putting in. Once school lets out, he finds himself working long hours nearly every day of the week. Although he has added workers, his business now handles mowing, trimming, and landscaping for residential, corporate, and nonprofit clients. He is considering adding managers but is not quite sure how to structure the organization. Lavell wants to focus on building the business rather than doing the daily work, so he knows a decentralized structure will be best. He has asked you to develop a potential organizational chart to help him envision the best way to organize the business. Describe the advantages to this approach as well as any concerns he should have.
