What is a true statement about acquisition strategies?

The statement that outsourcing software development can reduce control over quality is indeed true. When software development is outsourced, the control over the processes, standards, and quality of work shifts from the organization to the external vendor. This can lead to potential challenges, such as miscommunication regarding specifications, differing quality standards, and the reliance on the vendor's testing and quality assurance practices. Therefore, while outsourcing can offer benefits like cost reduction and access to specialized skills, it can also introduce risks related to maintaining the quality of the final product.

The other statements do not hold true universally: in-house software development may not always be more cost-effective, as it involves overhead costs that outsourcing may help mitigate; outsourcing does not guarantee better expertise, as the quality and qualifications of external teams can vary widely; and purchasing software can be beneficial, but it doesn't automatically surpass all other acquisition methods depending on the specific needs and context of the organization.
