MDM support tech

Answer 3

1) Process support mechanism focuses on facilitating interaction and help to govern the communication activities
2) these can select organisers derive information

   benefits:
   1) Increased cost control
   2) Increased productivity in
   3) improved customer service
   4)Support for total quality management activities(TQM)
   5)Reduce number of meetings
   6)increased automation of routine workflow

Question 4

GDSS
Group decision support system

Answer 4

1. An interactive computer based system that facilitates solution of unstructured problems by set of decision makers working together as groups
2. It aids groups especially groups of managers in analysing problem situations and in performing rogue decision making tasks
   Similarities between GDSS and DSS:
   1) Boot use models data and user friendly softwares
   2) both use internal and external data
   3) Both allow decision maker to take an active role
   4) Both have flexible systems
   5) Both have graphical output
   adv:
3. Anonymity
   Drive out of fear leading to better decisions from many decision makers
4. Parallel communication
   Eliminates monopolising that is involvement of single person
5. Portability
6. Ability for virtual meetings
7. Automated record keeping
8. Ease of use
9. suppresses negative group behaviour and increases positive growth behaviour
10. High level managers spend 80% of time in decision making in groups so GDSS can reduce time
11. provides hardware software’s database, procedures for effective decision making

Question 5

Distributed Group DSS
DGDSS

Answer 5

1. Designed to facilitate decision making amongst dispersed groups
   There are two types of GDSS :
   1) synchronous DGSS
   2) Asynchronous DGSS

The development and delivery platforms of DSS/GDSS are now shifting to the Web environment. A Web-based GDSS refers to a computerized system that provides decision tools and decision support information to its users who are accessing it via a Web browser (e.g. Netscape Navigator or Internet Explorer).

Question 6

EIS
Executive Information Systems

Answer 6

1. It is a Special type of DSS Software designed for top management for accessing info about companies performance, Overall operations and summary of what competitors are doing
2. These systems are generally easy to operate and present information in ways easy to quickly absorb like graphs charts etc
3. It is a tool which has died at to on line access to relevant information
4. It is timely and accurate
5. Easy to access

Question 7

components of EIS

Answer 7

Hardware Components
* An EIS requires no specific or unique hardware or peripherals other than those typically found in a modern client/server environment.
* The important considerations regarding sufficient RAM memory, hard drive space, removable storage, high speed graphics, large display terminals and data access, and multimedia capabilities relevant to any client-side setup are equally relevant in an EIS environment.
Software Components
* In contrast to hardware, software is usually highly specialized to the problem domain.
* This specialization is often achieved by using off-the-shelf components for the EIS backbone, and customized modules to meet specific needs.
Current EIS Technologies
 Dobrzeniecki proposed a three-tiered functional categorization:
Category 1: EIS products that include a full set of applications developed by the same vendor
Category 2: EIS products that are implemented on top of DSS products previously developed by the same vendor
Category 3: Applications that serve to bind together any number of products currently by the client organisation into a cohesive, integrated EIS.
