1. Define TPS and DSS and explain how an organisation can use these systems to make decisions and gain competitive advantage:
TPS is abbrieviated to Transaction Processing System which deals with the operating area of a business. It is dealt with by analysts at a lower level in the organisation. DDS is also referred to Decision Support System and it assists managers or executives in a decision making process.
An organisation uses these systems as the transaction processing system gives data to the decision support system hence they narrow down the details from the TPS and allows employers to make efficient decisions in the organisation.
2. Describe three quantitative models typically used by decision support systems:
Sensitivity Analysis - Baltzan,Phillips,Lynch and Blakey (2010) describe Sensitivity Analysis as "The study if the impact that changes in one (or more) parts of the model."
What-If Analysis - When a change is monitrored through a belief on a suggested mechanism.
Goal-Seeking Analysis - Where it locates the essential input to reach a particular goal.
3. Describe a business process and their importance to an organisation:
A business process is a set of activities that are used to accomplish certain tasks. This is important to an organisation as it helps them to look out for things such as tasks that are replicated and conjoined tasks in which they can get rid of to find processes that are well orderly runned. A business process also enables an organisation to achieve a set number of goals.
4.Compare business process improvement and business process re-engineering:
Below, I have created a table comparing business process improvement and business process re-engineering:
5. Describe the importance of business process modelling (or mapping) and business process models:
The importance is that business modelling shows the process in a manageable way and it consoles accuracy. Awareness is concentrated on the process model system and gives a highly effective interpretation. The importance of business process models is that it contains diagrams that illustrate a set of activities in a chronological order and analysis can be done on whether the organisation is achieving their goals and objectives.
An example of a business process model:
