Outsourcing software development is increasingly popular as it enables companies to leverage external teams for their projects, which can lead to cost savings and quicker scaling. Both onshore and offshore models have unique benefits and drawbacks, with onshore allowing for real-time collaboration and fewer communication barriers, while offshore can offer significant cost savings and access to a broader talent pool. Ultimately, the choice between onshore and offshore outsourcing should be based on specific organizational needs, budget, and the required level of involvement and communication.
