Agenda
Trends in information technology
Trends in Information Systems research
What I have learned in doctoral program– What is theory?
– What is good research?
– Why literature review is important
– Journals and conferences
Trends in Information Technology (3 P’s)
Price down
Pervasive
– Every where, any time, in any devices
Personalized
– Customized to each user’s needs and tastes
Price Down
Moor’s law
– Capacity of computers (same price) doubles in every 18 months
– Processor Memory Bandwidth Sensor
– Mega Giga Tera ?
New applications
– Convergence (PDA + PC + Cell phone + GPS + Camera + … )
– More intelligent system
Pervasive IT
Pervasive and ubiquitous computing devices
More devices will have integrated micro computer – Continuous sensing and data collection– Examples: E-Z Pass, PDA + phone, Smart Card, Active badge
More devices will be connected – Bluetooth – networking standard for nearby devices ( < 10m)– 802.11 – wireless network card standard– IPv4 IPv6
Recent technology– location aware devices (GPS), MEMS
Smaller and Smaller Devices
MicroElectroMechanical System (MEMS)
Location-Aware Wireless Internet
Personalized Information Systems
Customizing services for personal tastes
Internet technologies
– User configured system – Yahoo!, MSN
– Opportunistic links – travelocity.com, expedia.com
– Recommendations – amazon.com
Recent technology – location-aware personalization

Research Issues
Identifying customer tastes– How to identify and use customer taste information
Developing new services and application in the pervasive computing environments– What types of services and applications are possible– What application is good for what
How do people use new information technologies (IT) – Acceptance and adoption of IT– Impact of IT on people
Research Issues in Marketing
From Segmentation to personalization– Personalized marketing
– New type of marketing (real-time marketing)
Customer information overflow– Various sources of customer data
– How to extract useful information
Theory in Research
Theory – Tested model about the relationships between variables
Why is it important?– You don’t have to invent the wheel again
– A good thinking exercise
Good theory– Parsimonious
– Generalizable
What is Good Research
Rigorous (research methodology)– Reliability: repeatability
– Validity: generalizability
Significant (research topic)– Contribution to practice
– Simple
Journals and Conferences
Journal– Communication medium for researchers– Most journals are online
Why is literature review important?– Check if similar study has already been done– Know related research– Know research trends
Conference– Communication channel for state-of-the-art research– Networking with other people
How to Write A Paper (Thesis)?
Find interesting phenomenon
Search for previous studies and related studies– Develop “SPECIFIC” research questions (ask managers)– Find out what has been done
Framework development– Apply theories– Synthesize two or more theories (develop a framework)
Design research– Data collection methods (experiment/survey, sample/subject)– Analysis methods
