Is dedicating time to products which are likely to acquire very small business volumes worth the risk to an already busy manufacturing plant?

These products have to be newly launched products or test run products, it is always best to ad new products to the portfolio, but it has to be first tested in the market to see customer response and if the product shows good potential of adding to the profitability of the product range Yes then it is worth the risk, because any product has a life cycle either we need to relaunch existing products and or add new products in order ti keep the sales high
