WebFeb 18, 2024 · Maintainability index: Once written, code needs to be maintained. The ease/difficulty of maintaining the code determines the quality of the system. 0 to 9 indicates low ability to easily perform maintenance: 10 to 19 indicates modest ability to perform maintenance: 20 to 49 indicates moderate ability to perform maintenance Maintainability Index originated as an internal project at HP to help drive decision making around their software processes, and the coefficients within the metric equation directly reflect this. Within HP, engineers were asked to rate the maintainability for 16 projects on a 0 to 100 (excellent … See more The Maintainability Index first appeared in 1992 when it was proposed byPaul Oman and Jack Hagemeister at the International Conference on Software Maintenancewith the goal of … See more The goal behind the Maintainability Index is great - having an easy metric tomeasure the costs to maintain and maintainability of a project is important -but the technical details behind the … See more The original Maintainability Index had an upper bound of 171 and no lower bound.In general, in the original paper, the authors recommended that MaintainabilityIndex primarily be used to … See more Overall the Maintainability Index gives us an interesting tool to examine thepotential costs of maintaining different projects or different parts of ourproject.
