Workflow and document management systems

DMS is an ICT system that keeps track of electronically stored documents , paper documents are still used in companies so these need to be scanned in so they can be digitised.

Work flows between many different people in an organisation as different people are responsible for different tasks

Workflow management provides automatic routing of documents to the personnel responsible for that area of the business. Each person is responsible to complete a step in the business cycle. This does not depend on manual flow of document. It uses databases and networks so that each user is able to access the data.

Management information systems (MIS)

This is an ICT system that is designed to take internal and external data and turn it into information. This is converted into an appropriate and understandable form that will allow managers at different levels in an organisation to make an informed decisions.

  • Managers are able to make effective decisions for planning, directing and controlling the activities for which they are responsible.
  • MIS are designed primarily with the information needs of managers in mind

Problems

  • Many managers do not understand the role of information
  • To a manager, having lots of correct info reduces uncertainty when making decisions, this then creates a better outcome overall for the company

Decision support systems

This is a type of system that supports the decision making process, for example if there are 3 different ways of making a profit for the company then the DSS will guide them on which is the most profitable. 

Also they can be used to extrapolate figures to provide forecasts (future sales)

This type of system can mainly be used by the senior management team as they will need to make the crucial decisions about how the company functions and what the next steps are in the future of the company.
