1. When you do lot more yourself, there is a risk of burn out, risk of breaking something and also small teams have the luxury to fail fast and deploy more frequently which enterprises dont dare to do and now with more CI/CD guidelines enterprises are getting there to iterate faster. 2. Small teams have the luxury to communicate faster and less noise when communication happens. Less heads involved in decision making , also problem of hierarchy of chains to pass through before something is started. 3. Enterprises sometimes under-estimate the power of development environment setups. I know you might wonder why this point is here but if developer has luxury to setup environment quickly and efficiently without spending time on setting up dependencies lot gets done faster.
