Systems Operation and Support
Four classifications of maintenance
Corrective maintenance
Example: A user submits a
systems request with supporting evidence
Adaptive maintenance
Example: Users have been logging on to the software from a social media platform with no problems for the past few days
Perfective maintenance
Example: Re-organizing data sets within a database so they can be searched faster or use less storage or providing shortcuts commands that experts can use instead of the slower standard menu system
Preventive maintenance
Example: regular cleaning, lubrication, replacing of parts, and equipment repairs
response time
the overall time from the request of any activity related to the system to the delivery of that request to the user
Configuration management
is a systems engineering process for establishing consistency of a product's attributes throughout its life
helps engineering teams build robust and stable systems through the use of tools that automatically manage and monitor updates to configuration data
release methodology
is a process that entails the management, planning, scheduling, and controlling of an entire software build through every stage and environment involved, including testing and deploying software releases
Cons
: lack of process description, too high release distribution rate, and poor traceability between incident records and release records
Pros
: fewer defects, increased predictability, excellent compliance, and reduced costs
turnaround time
evaluate system performance both before and after changes to the system or business information requirements
the amount of time taken to complete a process or fulfill a request
bandwidth
the maximum amount of data transmitted over an internet connection in a given amount of time
throughput
a measure of how many units of information a system can process in a given amount of time
