Chapter Two Questions
1. Define TPS & DSS, and explain how an organisation can use these systems to make decisions and gain competitive advantages
TPS: Transaction Processing Systems used by analysts comprises of Transactional Information: This process is used to support the performance of daily operational tasks e.g ATM's This information is used to analyze sales and demand - while determining how much inventory to carry. Also Analytical Information: used to support the performance of managerial analysis tasks - Transactional, market and industry information e.g trends, sales and product statistics, and future growth - Managers use this information before making decisions within the organisation. Other TPS are Online transaction processing OLTP and Transaction processing sys TPS and Online analytical processing OLAP.
DSS: Decision Support Systems used by Managers mainly and like the TPS system these ensure that businesses have information available and to assist in decision making processes and problems solving and opportunity solving. EIS: Executive Information Systems used by Executives to analyse data internally and externally within an organisation - consolidation of information, Drill down information within a desired time period and Slice and dice information from different perspectives.

2. Describe the three quantitative models typically used by decision support systems.
1. Sensitivity analysis: Studies the impact of changes and how these changes affect other variables.
2. What-if analysis: Studies the impact of change in an assumption and analysts continue to repeat this in various situations
3. Goal seeking analysis: Studies the inputs used to achieve a desired goal by setting target value/goals for a variable and then changes other variables until the target/goals is a achieved.

3. Describe a business processes and their importance to an organisation.
"A business process is a standardised set of activities that accomplish a specific task, such as processing a customers order". E.g Paying for groceries "Purpose" at the checkout "Process. These processes transform a set of inputs into a set of outputs (goods or services) while ensuring organisations "anticipate bottlenecks, eliminate duplicate activities, combine related activities and identify smooth running processes - while achieving goals.

4. Compare business process improvement and business process re-engineering.
"Business Process Improvement attempts to understand and measure current process and make performance improvements accordingly".
Business Process Re-engineering "assumes that the current process is irrelevant, does not work, or is broken and must be overhauled from scratch". Looks at taking a completely different path instead of trying to improve the current process.

5. Describe the importance of business process modelling (or mapping) and business process models.
Business Process Modelling is created to ensure businesses have a detailed flowchart or process map of desired goals and the tasks/inputs and activities needed.
Business Process Models expose process detail and in a controlled manner, encourage conciseness and accuracy in describing the process model, focus attention on the process model interfaces and provide a powerful process analysis and consistent design vocabulary. E.g As -is process to To-be process of ordering a hamburger.
