(2016): “Impact of Marketing Information System on Product Performance in Nigerian Bottling Company Limited” KIU Journal of Social Sciences, 2(2): 221 – 236Many organizations fail to realize that the survival of their products in the competitive market is a function of their commitment to building and maintaining reliable marketing information system that is encompassing and embracing. This is because many companies in developing countries are often successful for a short period of time as they launched a new attractive product or an appealing service, but find it difficult to sustain over a longer period of time due to failure to continually gather information about the changes in market situation. Thus, this study examined the impact of marketing information system on product performance in the marketing department.
