After the project is up and running, it requires maintenance and this is the final stage in the Product Development Lifecycle. This phase is important since it has to ensure that the project is running at peak performance levels while fixing bugs and improving it regularly.
The first step is to restructure the team so that it is able to respond to any possible issues during the application maintenance or site maintenance. However, this is not always necessary and depends on the project itself.
The team has several tasks to perform during this stage. One of their main tasks is to fix bugs and address the issues discovered after the release stage. Other tasks include implementing new features and improvements occasionally. Depending on the product needs, Product Increments can be created and applied every 1 to 4 weeks.
Maintenance is the longest phase of the Product Development Lifecycle.
