Although updates have become the rule rather than the exception in modern digital ecosystems, to date they have received little attention in the IS post-adoption literature. We therefore draw on the IS continuance literature and expectation-confirmation theory to investigate, how different delivery strategies of security and feature updates impact users’ continuance intentions (CI). Based on an online experiment with 282 participants, we find a positive effect of security updates on users’ CI only if users are notified after successful implementation. Feature updates, in contrast, elicit a positive effect on users’ CI if they are at least announced before or after successful implementation. We also find that this positive effect of ex-ante announced feature updates diminishes if users have the choice to consume the update or not. In essence, our findings contribute to IS research by extending the mostly monolithic view of information systems by showing how an alterable information system might influence users’ attitudes and behaviors during use. For practitioners, we show that it seems to be beneficial to inform users about updates, even though a silent integration has become possible with modern digital ecosystems, and that updates should be applied consistently. Directions for further research are discussed.
