Outsourcing is cost-efficient and saves a lot of time; the two most fundamental resources of any business or organization for a successful establishment. The decision to outsource or hire an in-house team depends on the nature of the project and the financial resources of the organization. The effectiveness of the choice doesn’t depend on just one factor. In fact, the results may change the second time depending on the investment and the resources spent on software development. All that matters is the software development strategy.
The success of the project is not inherently dependent on either of these methods. It depends on various factors and metrics. It just boils down to the advantages one has over another. But it’s like comparing apples and oranges- all subjective!
