Ability of a system to handle an increasing amount of work by adding resources to it Scalability is the property of a system to handle a growing amount of work by adding resources to the system.[1] In an economic context, a scalable business model implies that a company can increase sales given increased resources. For example, a package delivery system is scalable because more packages can be delivered by adding more delivery vehicles. However, if all packages had to first pass through a single warehouse for sorting, the system would not be as scalable, because one warehouse can handle only a limited number of packages.[2] Examples[edit] The Incident Command System (ICS) is used by emergency response agencies in the United States.
ICS can scale resource coordination from a single-engine roadside brushfire to an interstate wildfire. Dimensions[edit] Scalability can be measured over multiple dimensions, such as:[6] Domains[edit] Horizontal (scale out) and vertical scaling (scale up)[edit]
