Scientific and empirical studies reveal that despite the implementation of new product development best practices, there are still many projects that fail within the framework of new product strategy. It means that costs are incurred by many stakeholders making up a specific network of relations, and not just enterprise. The conditions, under which companies operate, also affect strategic marketing and operational activities of the organisation. It is therefore no surprise that identifying and managing NPD have become increasingly important issues in the product innovation literature and practice. The main purpose of this conceptual article is to show interrelations between the level of the maturity progression of the new product development process (maturity growth of NPDP) and the level of security and success of a new product in the market. The article is to propose the conception of measuring the level of maturity progression of the new product development process in the context of its safety and success as well as managerial implications of the proposed measurement conception.
