ISVs, from startups to large enterprises, face this challenge at some point. As the app scales, it needs more skilled resources just to maintain its functionality. The lack of resources can create severe complications for Salesforce ISVs to succeed, constraining their capability to build and scale up their apps, leading to failure in meeting the product roadmap, longer than planned time to market, missed opportunities, and more.
While there are many ways to solve this problem in the long run, outsourcing their development needs to more skilled resources can solve it very quickly. ISVs will have access to a wider pool of technical talent who are highly trained in Salesforce development and testing.
