When you choose software development outsourcing, you delegate a project to another team and pay only for the result. For instance, a founder wants to redesign their app, and they ask a design agency to do it for them. Outstaffing works differently: instead of delegating the project, you hire skilled professionals and manage them directly. In this case, you pay for their time and experience, and you can achieve the desired result in any way you deem necessary — unlike software development outsourcing, when you have no control over the processes in another company.
