The subject of this paper is the development of new products at Splitska banka. The product is the result of a production that meets the needs or desires of consumers. When designing a product concept, its market characteristics are taken into consideration, such as product quality, assortment, sales price, aesthetics of products, packaging and packaging, marking and equipping of products, product modernization, consumer services and warranty and service. The development of a new product includes several phases, namely generating ideas, examining and selecting ideas, developing and testing concepts, developing a marketing strategy, business analysis, product development, testing (marketing) and commercialization. Once the product is launched, it follows the process of its acceptance or diffusion of the product. Although the goal of each company is to develop a product that will last as long as possible, each product has a life cycle. The concept of a product's life cycle includes the introduction phase, the growth phase, the maturity phase, and the decomposition phase. In the practical part of this paper internet and mobile banking are analyzed as new products of Splitska banka. At the end of November of 2015 Splitska banka launched SB SmartNet Internet and Mobile Banking. The biggest benefit of the new products of Splitska banka is that it enables its customers to make almost every operation of internet or mobile banking with three clicks. That is useful for clients, as well as for the bank because it requires less programming, and thus fewer bug development options. Despite the minor shortcomings, SB SmartNet Internet and Mobile Banking have promoted Splitska banka as one of the most technically advanced banks in the Republic of Croatia.
