Doing more with less in terms of resources invested in business, and, where possible, controlling the resources without owning them refers to:

The concept of "doing more with less" and controlling resources without necessarily owning them is often associated with the term "resource efficiency" or "resource optimization." It involves maximizing the output or value generated from available resources, whether they be financial, human, or material, in order to achieve greater efficiency and effectiveness in business operations.

Another related concept that specifically focuses on controlling resources without necessarily owning them is "outsourcing." Outsourcing involves contracting out certain business functions or processes to external providers, allowing a company to benefit from the expertise and resources of those providers without the need for direct ownership.

In summary, the idea of "doing more with less" and controlling resources without ownership can encompass both resource efficiency and outsourcing strategies in business.
