Transaction Processing Systems are the basic systems of a business that manage and operate elementary business activities. These activities are processed on an operational level meaning it is done regularly or day-to-day by analysts. TPS have been improved to operate in real time and also online making transactions faster and more efficient in the workplace giving the business a competitive advantage.Decision Support Systems help give managers the support they need in order to improve decision making hence improve the business' competitive advantage. It does this by summarising and analysing information from TPS and using that information to determine decisions.
2.Describe the three quantitative models typically used by decision support systems.
Three quantitative models used by DSSs include sensitivity analysis, what-if-analysis and goal-seeking analysis. Sensitivity analysis is the study of the impact that changes in one (or more) parts of the model have on other parts of the model. What-if analysis checks the impact of a change in an assumption on the proposed solution. Lastly goal-seeking analysis finds the inputs necessary to achieve a goal such as a desired level of output.
WHAT-IF-ANALYSIS = What if sales increase or decrease?
GOAL-SEEKING ANALYSIS = What sales price do I set to break even?
3. Describe a business processes and their importance to an organisation.
A business process is a standardised set of actions that together accomplish a specific task for example processing a customer order. Business processes are very important to an organisation as they can be analysed to see if the business' inputs are being used effectively. By examining these processes it will also assist to improve efficiency and effectiveness within the organisation. Business processes transform a set of inputs into a set of outputs for another person or process by using people or tools, such as a customer checkout process which improves efficiency.

4.Compare business process improvement and business process re-engineering.
A business process is a standardised set of activities that accomplish a specific task, for example processing a customer’s order. Business processes transform a set of inputs into a set of outputs for another person or process by using people and tool which is a customer checkout process. Examining business processes helps an organisation to anticipate blockages, eliminate duplicate activities, combine related activities, and identify smooth-running processes. To stay competitive, organisations must optimise and automate their business processes. Developing logical business process can help an organisation achieve its goals. For example an automobile manufacturer might have a goal to reduce the time it takes to deliver a car to a customer. The manufacturer can not hope to meet this goal with an inefficient ordering process or convoluted distribution process. In comparison a business process re-engineering is the examining and altering of workflow between and within organisations. It is the analysis and redesign of a workflow within and between enterprises. BPR changes the current business processes entirely assuming they do not work and need to be fixed. It starts from the beginning to create a whole new set of processes that will improve the competitive advantage of a business.
5. Describe the importance of business process modelling (or mapping) and business process models.
Business process modelling is the activity of creating a flowchart or process map of a work process. It shows its inputs, tasks and activities in a structured sequence. A business process model is a graphic description of a process. It shows the sequence of process tasks, which is created for a purpose and from a viewpoint. These processes allow an organisations to see where improvement may be necessary or which parts could be altered to improve competitive advantage which hence make it important to businesses. The importance of these models is the process which allows a competitive advantage as it encourages conciseness and accuracy, focuses attention on the process, provides a powerful analysis and consistent design vocabulary.
