The maintenance phase of the SDLC occurs after the product is in full operation. Maintenance of software can include software upgrades, repairs, and fixes of the software if it breaks. Software applications often need to be upgraded or integrated with new systems the customer deploys.
What is the maintenance phase?
Maintenance phases are short periods of elevated Calories, throughout a longer-term weight loss goal. Another term often used is ‘diet break’.

Which activity is involved in maintenance phase?
During the maintenance phase, errors or defects may exist, which would require repairs during additional testing of the software. Monitoring the performance of the software is also included during the maintenance phase.
Which stage of software development is most expensive?
Maintenance is the most expensive and time consuming task. After Maintenance, Implementation is the most expensive task.
What type of maintenance is Y2K?
Y2K problem is an interesting example of the role of maintenance in software. (Y2K was the need to fix software that handled years as two-digit numbers when the calendar switched from 1999  to 2000 . Some programs took that to mean that time had moved backwards.)
Why the system maintenance phase is often the most expensive phase?
The primary reason that the maintenance phase last longest is the life of the software. Most software programs remain in operation until they become obsolete due to changes in a user’s needs or until the cost of maintaining the software becomes prohibitive to future use of the software.
