why is maintainability important

We would see below what importance these parameters play in developing/writing quality code. Key metrics to measure the quality of code are reliability, maintainability, testability, portability, and reusability. Every now and then I come across people (mainly managers of multinational companies that operate software systems) who are uncomprehendingly looking at me while listening to the argumentation about the importance of source code maintainability. This definition suggests another reason why maintainability is important: you don't want to make changes to software in production use that negatively affect users (i.e. The maintainability of a software application is the most important attribute after safety. While benchmark MTR values vary across different types of equipment used in different industries, working to keep MTRs low is a basic step to improving maintainability. Improving maintainability Improving the process of actually doing repairs increases the maintainability of an asset and of the plant. Maintainability is a long-term aspect that describes how easily software can evolve and change, which is especially important in today’s agile environment. Software maintenance has become an important part of development of the software after its execution. Roughly speaking, maintainability is inversely proportional to the amount of time it takes a developer to make a change and the risk that change will break something. This chapter introduces RAM, what it is, why it is important, Abstract: Being highly maintainable is the key to reducing approximately 75% of most systems' life cycle costs. Software maintainability is important because it is approximately 75% of the cost related to a project! It addresses reliability, availability, and maintainability (RAM) as essential elements of mission capability. Poor Code Quality Software Dies Early. Author: Tibor Bakota. This short instructional video discusses four important reasons why we do RAM (Reliability, Availability, and Maintainability), and why RAM is important. Software maintenance wipes out lots of issues that software carried out formerly might face due to alter of hardware. Software maintainability is defined as the degree to which an application is understood, repaired, or enhanced. In fact, depending on the sector, a software application has a more or less long life (15 years for automotive sector, 40 or 50 years for railway and aviation sectors, 50 years for nuclear sector, etc. It focuses on what can be done to achieve satisfactory levels of RAM and how to assess RAM. It's a continuum. This is not an issue faced in development. Software Maintainability: 75% of Your Budget Is Dedicated to Software Maintenance. that objective. by introducing new defects in previously working functionality).
