The document outlines a presentation on system maintenance given by five students at Green University of Bangladesh. The presentation covers objectives like explaining the systems support and security phase. It describes user support activities including training and help desks. It also defines the four types of maintenance and techniques for managing maintenance and support. Specific topics discussed include user training, the different types of system maintenance, the systems development lifecycle, maintenance management, impact analysis, system security, backup/disaster recovery, and future challenges.

4. Introduction
Managing systems support and security involves three main concerns: user
expectations, system performance, and security requirements
Successful, robust systems often need the most support
In most organizations, more than half of all IT department effort goes into
supporting existing systems

5. User Support
 User Training
 Additionally, new employees must be trained on the company’s information
systems
 User Training packages
 Training users about system changes is similar to initial training
 Objective is to show users how the system can help the perform their jobs

6. System Maintenance
 Modifications or corrections made to an information system after it
has been released to its customers
 Changing an information system while it is in operation
 Evolving an information system to adapt to changing business
conditions and user needs

10. Categories of Maintenance
Corrective - fixing bugs
Adaptive - no change to functionality,
but now works under new conditions
Perfective - adds something new; makes
the system “better”
Preventive - enhances internal structure
of system without affecting external
behavior

14. Impact analysis
During planning - determine modules that will need to be
modified, to estimate time and resources needed
During analysis - understand data and control flow in
order to follow chain of ripple effects
During design & implementation - keep track of what ripple
effects have been accounted for
During test - known ripple effects guide testing; further
testing reveals unknown ripple effects
