Published as Prentice Hall 9/21/2015 Collaboration Technologies 8-17 Helps bring together the right combination of people who have the appropriate set of knowledge, skills, info and authority to solve problem quickly and easily. Replaces ‘taskforce’ (temporary workgroup) who cannot solve problem quickly. Bring about Virtual teams – dynamic task forces (that are Formed and disbanded as needed, have fluctuated team size & that have easy, flexible access to other team members) Technologies: 1) groupware 2) videoconferencing, 3) desktop conferencing

18 IS Today (Valacich & Schneider) Copyright © 2010 Pearson Education, Inc. Published as Prentice Hall 9/21/2015 Groupware 8-18 Class of software that enables people to work together more effectively Distinguished along two dimensions: 1) working together at the same time (synchronous) or different time (asynchronous); 2) working together face-to-face or distributed

29 IS Today (Valacich & Schneider) Copyright © 2010 Pearson Education, Inc. Published as Prentice Hall 9/21/2015 Knowledge Management Systems 8-29 Helps to store and disseminate knowledge assets. Knowledge assets are skills, routines, practices, principles, formulas, methods, heuristics and intuition, used to improve efficiency, effectiveness and profitability. They are usually documented in form of Databases, computer files, plans, manuals, diagrams & books. Includes Collection of technology-based systems including collaboration technologies (e-mail, groupware, instant messaging) and storage and retrieval systems (databases, data mining technologies). Commonly utilized the concept of knowledge portal (specific database connected via Internet used to share knowledge collected into repository with employees, customers, suppliers and general publics)

30 IS Today (Valacich & Schneider) Copyright © 2010 Pearson Education, Inc. Published as Prentice Hall 9/21/2015 Web-Based Knowledge Portals 8-30 Knowledge repository

31 IS Today (Valacich & Schneider) Copyright © 2010 Pearson Education, Inc. Published as Prentice Hall 9/21/2015 Geographic Information System (GIS) 8-31 A system for creating, storing, analyzing, and managing geographically referenced information. Examples of usage:  Finding optimal location for a new store  Identification of areas too wet to fertilize (see figure)  Locating target customers  Infrastructure design (e.g. building road, bridges)

32 IS Today (Valacich & Schneider) Copyright © 2010 Pearson Education, Inc. Published as Prentice Hall 9/21/2015 Geographic Information System Uses 8-32 Methods of usage: Customer dot mapping- used to map currents customers for store locations. Trade area analysis- assess where customers coming from by combining location info. E.g. drive time, to determine area under-serve or over-serve. Thematic mapping- using color code to map demographics information (e.g. income, household size) to identify potential customers.
