I would like to know why you decided to build your own framework in your company.
By framework, I don't mean few libraries you use often. I mean a specific way of building applications on top of it, with base classes, convention, etc.
So why did you built your own framework? How could you justify that to the person that employs you. Have you measure the positive and negative impact of it?
Regarding your experiences, did you notice that in some case a company framework produced real benefits, or on the other hand, increased costs of development (learning curve, debugging, maintenance, ...)?
