Which practice defines "outsourcing"?

Outsourcing is defined as the practice of engaging third-party firms to perform specific tasks or services that could be handled internally. This approach allows organizations to focus on their core competencies while leveraging the expertise and efficiencies that external providers can offer. Outsourcing can encompass a variety of functions, such as manufacturing, customer service, IT support, and logistics, among others. By doing so, companies can often reduce costs, enhance quality, and improve service levels.

In the context of the other choices, utilizing internal resources exclusively contradicts the essence of outsourcing, which relies on external collaboration. Employee-driven productivity emphasizes optimizing the workforce within the organization rather than seeking external solutions. Lastly, deploying technology without external help also does not align with the concept of outsourcing, as it implies a self-sufficient approach rather than leveraging third-party expertise. As such, engaging third-party firms accurately captures the essence of outsourcing and the strategic benefits it can bring to an organization.
