An ad hoc approach is a way of tackling a problem in an informal or spontaneous manner. In business, it is often used to describe a project or task that has no pre-determined structure, plan or timeline. This type of approach allows for flexibility, as changes can be made as needed without disrupting the overall process. It also allows time to come up with creative solutions to issues, as well as allowing individuals to work quicker without the risk of becoming too regimented or rigid. Ad hoc approaches are often seen as more effective when dealing with complex or challenging problems where standard approaches just won’t cut it.
