Mell What is meant by maintainability?
Maintainability is the measure of the ability of an item to be retained in or restored to a specified condition when maintenance is performed by personnel having specified skill levels using prescribed procedures and resources at each prescribed level of maintenance and repair.
What is maintainability with example?
Maintainability is defined as the probability of performing a successful repair action within a given time. For example, if it is said that a particular component has a 90% maintainability for one hour, this means that there is a 90% probability that the component will be repaired within an hour.
What is maintainability in coding?
The purpose of maintainability is to ensure that, over time, a program can be easily maintained. A programmer may decide to return to a program they wrote some time before in order to add an extra feature. Additionally, another programmer may wish to modify the program in order to improve it or debug an error.
What is maintainability in oops?
The goals of object-oriented programming are ease of maintenance, increased understanding, and ease of evolution. The features of OOP that make it maintainable are polymorphism, inheritance, data hiding, and encapsulation. Other two important features are coupling and cohesion.
What is the purpose of maintainability?
The purpose of maintainability is to improve effectiveness and efficiency of maintenance. One of the major products desired of such an activity is the optimization of building life—cycle costs.
What is true maintainability?
Explanation: Maintainability is defined as the ease with which the aircraft can be repaired or fixed. Vulnerability is related to damage taken. Explanation: Reliability and maintainability or R&M are often used together. It is measured in Maintenance man-hours per flight hour (MMH/FH).
Why is maintainability important?
The purpose of maintainability is to improve effectiveness and efficiency of maintenance. One of the major products desired of such an activity is the optimization of building life—cycle costs. Resources and procedures are dedicated solely to implementing appropriate levels of maintainability on the project.
How is maintainability calculated?
To measure the maintainability of an asset, you need to be able to quantify the amount of effort that is put into performing maintenance on that asset. While there are many methods to calculate the effort exerted, the most common way is simply by calculating the average time it takes to repair a piece of equipment.
What is abstraction in OOP?
Abstraction is the concept of object-oriented programming that “shows” only essential attributes and “hides” unnecessary information. The main purpose of abstraction is hiding the unnecessary details from the users. It is one of the most important concepts of OOPs.
Is data abstraction possible in OOP?
Data abstraction is one of the most essential and important feature of object oriented programming in C++. This is what abstraction is. Abstraction using Classes: We can implement Abstraction in C++ using classes. Class helps us to group data members and member functions using available access specifiers.
How is maintainability achieved?
Developers take care of maintainability by continuously adapting software to meet new customer requirements and address problems faced by customers. This includes fixing bugs, optimizing existing functionality and adjusting code to prevent future issues.
How do you improve maintainability?
How to improve maintainability
- Train your team better. The more training you offer your staff – especially new recruits, if your team has a high turnover – the faster they will act.
- Concentrate more information on each asset.
- Purchase similar equipment.
- Increase planned maintenance.
Why is maintainability an important aspect of quality?
Maintainability Is an Enabler for Other Quality Characteristics. Another reason why maintainability is a special aspect of software quality is that it acts as an enabler for other quality characteristics. When a system has high maintainability, it is easier to make improvements in the other quality areas, such as fixing a security bug.
Which is the best example of maintainability in software?
Imagine two different software systems that have exactly the same functionality. Given the same input, both compute exactly the same output. One of these two systems is fast and user-friendly, and its source code is easy to modify.
Which is better maintainable code or unmaintainable code?
For example, highly maintainable code is more stable than unmaintainable code: changes in a highly maintainable system have fewer unexpected side effects than changes in an entangled system that is hard to analyze and test. If maintainability is so important, how can you improve maintainability of the code that you write?
Is it possible to maintain a system in Java?
The average maintainability of all Java systems in our benchmark is itself average, and the same holds for C#. This shows us that it is possible to make very maintainable systems in Java (and in C#), but using either of these languages does not guarantee a system’s maintainability.
