Final answer:
Bricolage inherently relies on improvisation as it involves creating solutions with whatever is at hand, whereas business impact analysis is a systematic process that doesn't primarily rely on improvisation but rather on data analysis and planning.
Step-by-step explanation:
When comparing business impact analysis and bricolage in terms of requirements for improvisation, it is bricolage that inherently relies on it. Business impact analysis is a systematic process that determines the effects of interruptions to critical business operations due to disaster, accident, or emergency. It requires collection of data, analysis, and planning rather than improvisation.
On the other hand, bricolage is a term borrowed from the arts and refers to the construction or creation from a diverse range of available things, symbolizing improvisation and resourcefulness. Bricolage is like a puzzle where you create a new solution with whatever materials or ideas are at hand, much like a carpenter who must devise a solution when a standard method is not applicable. To improvise effectively, you draw from a wide pool of ideas, perhaps brainstorming alternative solutions, considering existing products, scientific principles, and any other creative approaches to solve a problem. In this light, bricolage is more about creativity and making do with what is available rather than following a structured method, thus it requires a higher degree of spontaneity and inventiveness.
