SRS Based Estimation of Software Maintenance Effort

Software maintenance effort estimation has always been a challenge for the software practitioners, as it consumes about half of the overall development costs. The effort required to develop or maintain software depend on the complexity of yet to be developed software. The proposed measure estimates the requirement-based complexity based on SRS document of yet to be developed software for systematic and early prediction of software maintenance effort using Software Requirements Specifications (SRS) document of the proposed software. The result obtained validates that, the proposed maintenance measure is a comprehensive one and compares well with various other prevalent measures proposed in the past. The computation of proposed maintenance effort estimation involves least overhead as compared to others.
