UI widgets are the most common. Redundancy must be accompanied by measures to ensure data consistency, and managed failure detection and switchover. Maintaining the software code quality by writing Bug-free and semantically correct code is very important for a good software project development. As software guru Martin Fowler said in Refactoring: Improving the Design of Existing Code, 1999, "Good programmers write code that humans can understand." Maintainability has previously been described mainlyin two ways, either informally or as a function of directly measurable attributes. Methods for doing so are in the scope of software engineering but not in the scope of this section. Maintainability—"The ease with which a software system or component can be modified to correct faults, improve performance, or other attributes, or adapt to a changed environment" [IEEE 1990]. And then next year, 15% of those lines need to be changed. Software maintainability is a crucial property of software projects. It can be defined as the ease with which a software system or component can be modified to be corrected, improved, or adapted to its environment.

An entity with relatively low costs in these areas is considered maintainable whereas an entity with high costs may be considered unmaintainable or "high maintenance." However, reliability and availability can also be increased through architectural redundancy, independence, and diversity. The following are illustrative examples. 2) Now show the Good code which has this method which calculates the mortgage payment in one and only place. Reverse Engineering is becoming important, since several existing software products, lack proper documentation, are highly unstructured, or their structure has degraded through a series of maintenance efforts. DHILLON, in Engineering Maintainability, 1999. BTW, I loved your approach of exposing the students to maintainability of the software. For implementing our design into code, we require a high-level functional language. Good coding in software engineering also helps to prevent errors, control complexity and improve the maintainability of applications. Manageability—How efficiently and easily a software system can be monitored and maintained to keep the system performing, secure, and running smoothly.

Project Code Meter Maintainability Index (MI) [article cited from Wikipedia] Maintainability Index is a software metric which measures how maintainable (easy to support and change) the source code is. Architecture Descriptions and Raw Source-Code: A Statistical Analysis of Maintainability Metrics. Maintainability: | In |engineering|, |maintainability| is the ease with which a product can be maintain... World Heritage Encyclopedia, the aggregation of the largest online encyclopedias available, and the most definitive collection ever assembled. The software engineering literature proposes many models and metrics to predict the maintainability of a software project statically. It’s not enough to measure code — it’s essential to understand and actually measure your software quality, and see if it is improving as a result of higher code quality. It represents the measure of code maintainability which is one of the software quality pillars. Lesson 2: Software Engineering Practices. Competitive salary. Verified employers. If you can, by all means make your code simpler. Maintainability is a key quality attribute of successful software systems. In a public payphone for example, the target Time to Repair might be 15 minutes (on-site time) to restore a faulty payphone to full working order. ISO/IEC-9126 Software Engineering-Product Quality Standard P ... mining to evaluate a software system’s maintainability according to the ISO/IEC-9126 quality standard. Maintainability: If the code is un-readable it's useless, no matter how fast it is. Code cloning is one of the active research areas in the software engineering community. Documentation. Reusability: Not all code is reusable, but a lot of it is. Software Reverse Engineering – Software Reverse Engineering is the process of recovering the design and the requirements specification of a product from an analysis of it’s code. Difficult-to-maintain source code is a big problem in software development today, leading to costly delays and defects. 2.1 Informal Descriptions There are many text descriptions available, which are in essence very similar. However, its management in practice is still problematic. I hope this article gave you an overview of what these best practices are. Software engineering is a discipline with largely invisible parts. It is code that can be understood by someone new - or someone that hasn't seen it in a while - with a minimum of effort. With respect to the environment and incentives in industry surrounding code maintainability, robustness, and testing, there are certain practices in place to encourage, enable, and ensure these qualities are met. The maintainability effort produces and uses a significant amount of information and data. Coding Best Practices in Software Engineering: Variables and Constants.
