The primary goal at this stage is to properly scope and deliver an MVP (Minimum Viable Product). Spend the least amount of effort needed to release a product that will start bringing value for customers.
The MVP will enable you to get your product out to the market and get feedback. Keep the product’s feature set as limited as possible to help reduce development costs.
Release small versions quickly and start collecting real product feedback from the market so you can focus product development efforts.
It’s important to maintain high-quality standards and a good balance between “perfect” and “quick”. It depends on your market and ICP, however in many cases some quality can be sacrificed at the MVP stage to allow you to gather quick, early feedback.
