Final answer:
The term space planning became prevalent in the 1980s as businesses sought high-performance office environments to match changing work practices and the rise of service-based economic activities.
Step-by-step explanation:
The term space planning took hold in the 1980s in response to the need for high-performance office environments. This was a period marked by significant changes in work practices and technological advancements that led to a transformation in what businesses required from their office spaces. During the 1980s, productivity growth in the United States had declined to lower levels following a high between 1947 and 1973. It was during this time that minimalist architecture, which emphasizes large open spaces with minimalistic designs, also gained popularity in cities like London and New York. As the American workforce transitioned from an industrial-based to a service-based economy, the emergent white-collar jobs influenced the demand for office environments that were designed to accommodate new work styles, improve worker productivity, and reflect the corporate image.
