Software updates have enabled developers the possibilities to fix bugs or add features after the initial software release. The phenomenon of using such updates to enhance software, is a relatively new trend that has not received much attention in the Information Systems (IS) literature. However, because software updates influence the interaction between users and developers, they are directly connected to sales and revenue. Based on a conducted literature review, this research idea consists of two parts and proposes an approach to measure and analysis the effects of software updates on users. First, a longitudinal, panel study is conducted to gain qualitative knowledge and extend the expectation-confirmation framework proposed by the existing literature. Second, a self-developed Android app will be used in an experimental setting to test and validate the research model and gain knowledge on how developers can keep users happy and increase continuance intention through functional software updates.
