1. List and describe the four basic functions of an information system. List and describe three types of enterprise systems.

- Input involves putting information into a system. Examples of input are keyboard, mouse, microphone or scanner (Brown et al, 2012). Input is pointless until it is processed and generated in some type of output.
- Output processes information into usable format. It comes in many different forms such as a printer printing a picture.
- Processing is converting inputted data into something usable. The information that you see on the computer screen is because of input that is getting process by some program so we can have usable output (Brown et al, 2012)
- Storage is the process of saving data for a period of time.

Enterprise systems are "software packages with integrated modules that can easily share data across dispersed work teams" (Brown et al, 2012, p. 3). Three types of enterprise systems are Transactional Processing Systems, Enterprise Resource Planning Systems, and Data Warehousing.
Transactional Processing Systems also known as the "grand-daddy" application - the ones that started it all. Transactional Processing Systems process thousands of transactions that occur throughout the day in most organizations. These transactions include sales, payments made and payments received; inventory shipped and received, hiring, firing, and paying employees (Brown et al, 2012). Organizations such as a bank or insurance company who deal primarily with paperwork rely heavily on transactional processing systems for the many reports that the system can generate.
Enterprise Resource Planning Systems are also a type of transactional processing system, but they go beyond the traditional processing systems functionality. According to Brown et al (2012, p. 198), enterprise resource planning system "is a set of integrated business functions or modules, that carry out common business functions such as general ledger accounting, accounts payable, and accounts receivable".
Data Warehousing is establishing and maintaining a large data storage facility that contains data on all aspects of the organization (Brown et al, 2012). Establishing a data warehouse is time consuming and quite expensive. Fir a data warehouse to be effective, the data must be accurate and current.

2. There are two fundamental requirements for managing business performance: being able to measure and knowing that your indicator is measuring the right thing. Explain each of these requirements and why they are challenging.

Being able to measure - You cannot effectively manage something that you cannot measure. Accurate and timely data will give a better result when measuring.
Knowing what your indicator is measuring the right thing ...
