Your big product idea should not remain un realized because of lack of resources. Outsource product development and focus on your users
Using software on a disc that is maintained by in house IT department on self owned servers is now passè.
Your big idea is your baby.
You have spent sleepless nights, defied naysayers and walked on broken glass to raise funds and build a team.
You know what the market wants. What remains is execution- turning an idea into a product. This is a huge hurdle, especially if you don't have the technical capability.
The ideal solution would be to build up your technical capacity. But that takes time. Another solution could be to outsource a part of product development to a technical partner.
