Using IS for Decision making

Levels of Decision making

Strategic decision making made by managers who are knowledge based and are used to dealing with major problems in the company.  These managers are there to provide the necessary support for the organisation and normally work in small groups.

First we should know that there are 3 different forms of decisions:

°         Structured decisions

°         Un-Structured decisions

°         Semi-structured

Structured decisions by contrast are repetitive, routine and involve a definite procedure for handling.

Unstructured decisions Where by the manager has to provide judgement, evaluation and insights into the problem definition.

Semi-structured decisions; clear cut answer provided by an accepted procedure.

Stages for making decisions include:

Intelligence identifies the problem, gather the information and communicate to the rest of the organisation.

Design: used to identify alternative solutions. DSS is used here.

Choice, were management chose among alternatives, keep track of consequences cost and opportunities.

Implementation, this is reporting on specific solutions and possible improvement actions.

Traditional MIS is information that can help identify problems in a system.

DSS can be used specifically in the design stage because these are simple models that can be quickly develop and with limited data.

Dublin’s tiger techland, it’s all good news

In the next article I found a lot of good news for does who are interested in choosing a carrier in IT, there is an abundance of work, in the technological sector. This article mentions all the top companies to work for: Facebook, Google, PayPal, Twitter, LinkedIn, eBay & Microsoft, with starting salaries of €47,000. I think it will be worth reading it.

MIS in Decision Making

To access information quick, efficiently and effectively management in a department may use information systems, to lessen the labour in the day-to-day running activities within an organisation. (e.g. accounts stock control, payroll, etc.)

Employees only need to enter the information into a computer program for file and analysis the managers can build programs to access the information and aid management more quickly in decision making for future development and direction to use against other competitors.

The information Age

To stay competitive management availed of the new technologies and processing data into information to use at a later date these new technologies, telecommunications, networks, E-mail, Voice mail, Internet, Telephone, etc. Through these technologies management can with speed and accuracy store large amounts of information.

Before the computer age, organisations had to waste vast amounts of time and resources in the collecting and storing of the information. After a few months the information would be useless a as information can be outdated as developments occur.  Organisations must keep on track with new technologies this information must be current and easy to access and at the same time available to different people at the same time. Firms have become most dependent of these new technologies or IT systems.

It is information that drives firms in staying competitive, and is this information system mechanism that managers avail when they for decision making is need it. These IT systems or computer programs can aid managers with the concise, relevant, timely and complete information.

Data driven DSS

Web-based DSS based on file drawer system that analyses, provides access to unstructured data and facilitates communication and decision making that is the backbone of any organisations decision making process. These are tools that are used in everyday business questions. These tools are process and methodologies that are key components for any DSS provides managers or decision makers in the organisation with comprehensive, monitoring and data analysis.

Web-based DSS Architecture,

  IS diagram    

 

 

High level decision making system requirements:

>Data collection from various sources, inventories market research, etc

>Data formatting and collation

>Suitable database location and format built for decision support-based reporting & analysis

>Robust tools and applications to report, monitor, and analyse the data

Business Intelligence

MicroStrategy is an example of a decision support system that provides companies with a unified reporting analytical and monitoring platform that forms the core of any DSS.

Supports individual and group decision making, easy to develop and deploy, comprehensive data access, integrated software & flexibility.

The use of DSS in management decision making

A DSS is an interactive computer base system. Decision Support System can aid managers in decision making without much programing effort, it is used to collect relevant data without rewriting the underlying MIS software application.

DSS allows managers in mapping out searching, retrieving and analysing decision relevant data. It allows more informed and educated decisions. DSS varies in scope and it can be used in many forms and in different ways, so it is of great importance for managers to understand that DSS can take many categories and make use of specific requirements.

One very important aspect of a DSS system is that they provide the information that is used in the decision making process. And more specifically the quality of the information, here are some factors that can be found in good quality information:

  • timeliness,
  • relevant,
  • accurateness,
  • consistency,
  • unbiased,

Sometimes information can be and often is misinterpreted, and this can lead to inaccurate conclusions, which at the same time affect the decision making process.

Next post I will talk about the many categories of Decision Support Systems.

Semi-structured decisions: clear cut answers provided by an accepted procedure.

Stages for making decisions include:

Intelligence: this method used by managers where through the gathering of information they can identify how well the organisation is performing, also where and when problems occur.

Design: at this stage managers can identify alternative solutions to the design and what level of intelligence is needed and it is also an appropriate solution to the problem. DSS can be used here for its simplicity and quick development.

Choice: through information tools management can chose among alternatives to calculate and keep track of consequences cost and opportunities. A larger DSS is used to develop e extensive data in a wider variety of alternatives and the use of more analytic models to address for all the consequences.

Implementation, this is reporting on specific solutions and possible improvement actions.

Traditional MIS is information that can help identify problems in a system.

DSS can be used specifically in the design stage because these are simple models that can be quickly develop and with limited data.
