What is system maintenance? List the reasons for systems maintenance.

stage of system development that involves changing and enhancing the system to make it more useful in achieving user and organizational goals -poor performance -changes in business process -changes in needs -bugs or errors in program -technical problems

Discuss the advantages and disadvantages of agile development.

+puts an application into production sooner than any other approach +documentation is produced as a by-product of completing project tasks +agile forces teamwork and lots of interaction between users and stakeholders -intense process that burn out system developers and other participants -requires system analysts and users to be skilled in agile system development tools and agile techniques -requires larger percentage of stakeholders' and users' time than other approaches

Briefly explain the difference between system testing and user acceptance testing (UAT).

-testing complete, integrated system, to validate that the information system meets all specified requirements -testing performed by trained system users to verify that the system can complete required tasks in a real-world operating environment and perform according to the system design specifications
