An organization plans to hire three external software engineers to build client software to connect its lightweight wireless devices to the cloud. It…

The scenario describes hiring external personnel for a project with a specific, fixed duration of six months, governed by a legal document. This arrangement is the definition of an independent contractor relationship. Independent contractors are non-employees engaged to perform specific work under a contract that outlines the scope, deliverables, and timeframe. They are not integrated into the organization's permanent workforce, which aligns with the "external" and "six-month" criteria provided in the question.

A. Full-time employees: This is incorrect because full-time employment implies an ongoing, indefinite relationship, not a temporary, six-month project-based engagement.

B. In-house expertise: This is incorrect as the organization is explicitly hiring "external" engineers, whereas in-house expertise refers to utilizing existing, internal employees.

C. Part-time salaried workers: This is incorrect because, like full-time employees, part-time workers have a continuous employment relationship, not a fixed-term contract for a specific project.

1. Cornell Law School, Legal Information Institute (LII). In its definition of "independent contractor," the LII clarifies that such individuals contract to perform work for another party but are not subject to the other's control over the manner and means of performance. This aligns with hiring external experts for a specific software development project. (Refer to the "Independent Contractor" entry in the Wex Legal Dictionary/Encyclopedia).

2. MIT Sloan School of Management. Course materials on strategic human resource management distinguish between core employees and contingent workers (including independent contractors). Contingent workers are utilized for their specialized skills on a temporary or project basis to provide organizational flexibility, which directly matches the scenario. (See materials from courses like 15.665 Power and Negotiation or similar HR management syllabi that discuss workforce structure).

3. Gregory, D. L. (1999). Employee or Independent Contractor: A Guide to the Legal Labyrinth. William & Mary Law Review, 41(3), Article 2. This academic article details the legal tests used to differentiate employees from independent contractors. A key factor discussed is the "length of time for which the person is employed" (p. 965), noting that a defined, short-term project duration is a strong indicator of an independent contractor status.
