OBJECTIVES THE ANALYST PURSUES IN DESIGNING SYSTEM OUTPUT

INTRODUCTION
In computer systems, output can be defined as anything that comes out of a computer. Output can be meaningful or just raw data. Output comes out of a computer in different formats such as pictures, text, binary numbers and printed pages. System output comes out from output devices such as loudspeakers, printers etc.

OBJECTIVES

System output needs to be effective. It should be able to serve its intended purpose for a specific user or the organization in order to be effective. System output also needs to be accurate and complete. It should therefore deliver the right amount of output and deliver the output to the right place, and the output needs to be correct. A good system output should be timely. This means that it should deliver the required output on time. For example, records in a bank need to be presented at a specific time in order to be deemed valid.
A good system output needs to be easy to user. A user should not struggle navigating through the output while looking for data. Its design should be attractive and user friendly. A good system output needs to simple. A simple structured output system is easy to understand and will not confuse the users of the system. A good system output needs to be consistent. Consistency in a system output is important in bringing a standard format, and without contradiction.

CONCLUSION

A good system output should therefore be able to deliver the intended output without errors, on time and the information must be accurate. The design should also be user friendly, attractive and easy to use.

PRINTERS AS THE BEST OUTPUT DEVICES
INTRODUCTION
Printers are among the oldest output devices and are also among the most widespread output devices. Printers these days are widespread not only in the big and busy organizations, but also in homes because they are convenient and give out accurate, precise and effective information.
OBJECTIVES
Printed out documents are convenient. For example, printed documents are convenient if you want to mark something on the document or add extra notes to the documents, you can easily do so. Printed documents are relatively smaller when folded compared to tablets and computers therefore easy to carry around. In case you lose your printed documents or damage them for example soak them in water, you can easily replace them hence they are very convenient and reliable.
Printed out documents are easy to read. So far, printed documents give the best display that other devices such as the iPad are unable to compare. As at 2012, printed out documents have better display than all output devices. Most people also find it easier to read printed material than softcopy material.
Printed out documents are secure in terms of delivery. Printed documents do not leave a record and therefore you can deliver them to wherever you want without them being intercepted or being altered. Delivery of printed documents is therefore safe and the contents of the documents being delivered cannot be easily altered or changed.
CONCLUSION
Printed out documents have various advantages over most forms of output data. Printed documents are convenient to use, secure to deliver and are by far the easiest form to read and use. They are also easily available in all corners of the world.
