Transactional Processing Systems (TPS) includes all the information contained within a single business process. Its main purpose is to support the performance of daily operational tasks. An organisation can use this system to record daily operational data such as credit decisions and cash deposits. It helps in supporting daily operational tasks at the time that they take place. This would help in keeping up to date with all records in order to look back and make decisions on what should stay the same or what should be changed in the operational sides of the business.
Decision Support Systems (DSS) allows managers to go through the decision making process with ease as they would have captured all the necessary information to come to a good decision. An organisation can use this system to decide on good outcomes to ideas which they would like to see take place the company. This allows them the managers to determines whether the new decisions should take place or whether operations should remain as they are. Competitive advantage- This allows organisations to create new innovative ideas which competitors haven't decided on and come to the conclusion whether it will help the company or not.
2. Describe the three quantitative models typically used by decision support systems
1) Sensitivity Analysis: The study of the outcome that one or more changes in the model have on the other parts of the model. It deteremines what would happen if a change in the organisation takes place.

2) What If: Checks the outcome of a change, before the idea takes place. It determines the end result when asking the question "What if" something in the organisation was to be changed.Below: An image of What If analysis using Excel

3. Describe a business processes and their importance to an organisation.
A business process is standard activities that accomplish a specific task, such as processing a customer order or enrolling students. Their importance to an organisation is that they help to create small changes and improvements in the way operational tasks are currently completed.
4. Compare business process improvement and business process re-engineering.
BPI- Models based on improving current processes. It looks at ways to improve operational tasks into more effective an efficient ways. An example includes digitalising forms, which are easier to back up instead of storing pages of papers away. BPI aims to make small improvements along the way, while measuring current processes.
Below is a link to an example of a BPI

BP re-engineering: Usually sets out new standards for the industry while improving the experience for the company. This looks at ways to keep the business working well for its customers and it employees . It assumes that the current ways of carrying out tasks is not working well and therefore needs to be re-built from scratch.

5. Describe the importance of business process modelling (or mapping) and business process models
Business Process Modelling- Activity of creating flow charts that show the inputs, outputs and processes of each step involved with a chosen work process. Its importance is to show:
-Detailed processes involved within each step.
-Focuses on the process model interface.
-Focuses on describing the process model with accuracy.

-Display process detail gradually and in controlled manner
-Encourages accuracy in describing the model using graphics.
