Recent Research in Information Systems

Is Software Better Off in the Cloud?

Abraham (Avi) Seidmann

Nowadays, businesses are turning more and more to the use of cloud services. Software applications and services known as software as a service (SaaS) are available online on demand. In this way, SaaS brings corporate users an alternative to modifiable off-the-shelf software (MOTS). A new study by Abraham (Avi) Seidmann, Xerox Professor of Information Systems and Operations Management, and Dan Ma ’03S (MS), ’06 (PhD) of Singapore Management University, shows MOTS packages still have an important role to play. They built a game-theory model to study the competition between SaaS and MOTS.

Is Good Customer service a popularity contest?

Huaxia Rui, Abraham Seidmann, and Priyanga Gunarathne

Recent research by Simon faculty shows that for customers with a problem to be solved, Twitter is the way to go—as long as they have a lot of followers. In their paper, “Customer Service on Social Media: Do Popularity and Sentiment Matter?” professors Huaxia Rui and Avi Seidmann and doctoral graduate student Priyanga Gunarathne gathered over a half-million tweets sent to and by American Airlines, United Airlines, and Air Canada.

Online Reviews Prove Trustworthy

Huaxia Rui and Susan Lu

A new paper by assistant professors Huaxia Rui and Susan Lu suggests that despite media criticism to the contrary, online physician reviews can be trusted, at least those of cardiac surgeons. The paper, “Can We Trust Online Physician Ratings? Evidence from Cardiac Surgeons in Florida,” is the first to look systematically at the correlation between online ratings and medical performance.

Upgrade Intervals Affect Profitability

Abraham Seidmann, Amit Mehra, and Probal Mojumder

In a new paper published by Production and Operations Management Journal, “Product Life Cycle Management of Packaged Software,” Simon professor Abraham Seidmann and co-authors Amit Mehra and Probal Mojumder study the optimal intervals between software upgrades and analyze how these intervals change over a product’s life cycle.
