The document discusses the stages of business development. There are typically five stages: 1) pre-venture or seed stage where opportunities are identified but concepts are unclear, 2) startup stage where the business is launched and initial customers are gained, 3) growth stage with expanding sales, customers, and staff, 4) maturity stage where the business model is established but further growth is unlikely, and 5) revitalization stage where changes are made to respond to new challenges or opportunities. Each stage involves different activities, with the pre-venture stage focusing on exploring ideas and developing a business plan.
