Since the outsourcing company is usually located in another country, some challenges come from working with a remote team. But you can overcome them using the proper project management and software development approach. For example, we use Agile, working in small but consumable increments. As a result, you have a hands-on approach that gives you control over what gets done and how, and you are always aware of our progress.
Another challenge can be cultural differences. These matter the most when working with a team from an entirely different culture than yours. Of course, you can mitigate these risks by implementing the right communication tools and having a clear collaboration outline.
Overall, working with a dedicated team can be beneficial, but it's important to be aware of the potential challenges and work to mitigate them. Clear communication, established quality standards, and a strong working relationship can help ensure a successful project outcome.
