Abstract: In this paper we address the problem of increasing software maintenance costs in a custom software development environment, and develop a stochastic decision model for the maintenance of information systems. Based on this modeling framework, we derive an optimal decision rule for software systems maintenance, and present sensitivity analysis of the optimal policy. We illustrate an application of this model to a large telecommunications switching software system, and present sensitivity analysis of the optimal state for major upgrade derived from our model. Our modeling framework also allows for computing the expected time to perform major upgrade to software systems.

Determinants of Mobile Apps' Success: Evidence from the App Store Market
Gunwoong Lee,T. S. Raghu +1 more
TL;DR: It is found that broadening app offerings across multiple categories is a key determinant that contributes to a higher probability of survival in the top charts, and sellers must utilize the natural segmentation in consumer tastes offered by the different categories to improve sales performance.

From representation to mediation: a new agenda for conceptual modeling research in a digital world
TL;DR: A new theoretical framework of conceptual modeling is developed that delivers a fundamental shift in the assumptions that govern research in this area and can make traditional knowledge about conceptual modeling consistent with the emerging requirements of a digital world.

The end of the information system life: a model of is discontinuance
Brent Furneaux,Michael Wade +1 more
TL;DR: A theoretical model of IS discontinuance that seeks to account for organizational intention to discontinue the use of an information system is offered, based on the premise that forces contributing to the formation of discontinUance intentions are opposed by inertial tendencies in favor of the status quo.

Impediments to Information Systems Replacement: A Calculus of Discontinuance
Brent Furneaux,Michael Wade +1 more
TL;DR: The proposed model of discontinuance calculus demonstrates the importance of managing risks, system complexity, and system investments to ensure that obsolete systems do not become a significant impediment to organizational effectiveness.

Does complexity deter customer‐focus?
TL;DR: This article studied how firms respond to customer requests for incremental product innovations, and how these responses change when the requested innovation is complex, finding considerable variance in the relationship between customer demands, complexity, and investments in incremental innovations.

Software complexity and maintenance costs
TL;DR: Before empirical evidence linking software complexity to software maintenance costs is relatively weak, several researchers have noted that such results must be applied cautiously to the large-scale commercial application systems that account for most software maintenance expenditures.
