Scrum Software Maintenance Model: Efficient Software Maintenance in Agile Methodology

Agile methodologies gained fame due to the fact of producing high-quality software systems. Maintenance effort is almost more than half of the total effort invested in any software system during its lifespan. A well-discussed issue within the community of researchers and engineers is how to use agile methodologies for maintaining the developed software because agile software development life cycle doesn't have the specifically planned mechanism for maintenance. To bridge this gap, we used the theoretical and empirical technique to formulate factors that should be followed during the agile maintenance including planning for the maintenance; the on-site customer should be present, iterative maintenance, documentation update after each phase and maintenance should be testable.
