Scalability refers to the ability of a system, network, or process to handle a growing amount of work or its potential to accommodate growth. In technology, this often means that a software application can manage increased user demand without sacrificing performance. For example, a website that can support more visitors as its popularity increases is considered scalable. In business, scalability indicates how well a company can expand its operations without a proportional increase in costs. A scalable business model allows for growth through increased sales or market reach while maintaining efficiency. This is crucial for startups and entrepreneurs looking to maximize their potential in competitive markets.
