Top 6 Characteristics Of A Well-Developed Software


To fabricate good quality software and make it quirky, you should pay heed to the characteristics of software design, well-developed software will make your software stand at an advantage from your adversaries.

But what are the factors which measure the quality of good software design? A software product is said to be good software if it proffers the features required by the users.

This article will delineate the characteristics of good software must-have. If your software has all such attributes, then it adheres to the norm of excellent software.

Certain factors which the developers should observe in the well-developed software are as follows-

Correctness

Your software is of no use if it is not correct. Besides making it easy to navigate and appealing, you should ensure the correctness of the software. The evaluators assess the software for input and action. Then they examine the results produced by the software according to the design.

Software is considered acceptable only if the results produced for specific inputs adhere to the design and help the software to function correctly.

Understandability

A software design that is easy to understand by the developers stands at a better position than a design that is difficult to explain or understand. Developers have a preference for self-explanatory software design.

There are thousands of developers that create different modules of the software. Explaining each module of the software out there in the market is a difficult task.

Besides being time-consuming, the complex procedures of the modules may not be understood by the developers. So, an easy and self-explanatory design would facilitate the developers to create the same software exhibited by the design.

Efficiency

Efficiency refers to creating software that fulfills the requirements of the target audience at optimum costs. We can estimate the efficiency of software or the attributes of good software from its design phase.

This is because if the design of the software is not efficient, then the created software will also not be efficient and useful. So, the developers must take care to integrate efficiency during the designing process. 

Efficiency is a diverse topic and it should be analyzed to a specific resource like the storage space or the execution time. You can also measure efficiency by analyzing the speed of the execution of a program.

Another measure of efficiency is the storage space required by a program for execution. These two measures of efficiency are inversely related. This is because an increase in the execution efficiency causes a simultaneous decrease in space efficiency.

This relationship between the two measures of efficiency is also called the space-time tradeoff. 

Hence, in cases when it is difficult to design a software product with efficiency in each aspect, the most critical resources of the software should be prioritized.

Maintainability

Maintainable software design is easy to modify according to the dynamic trends of the environment. This is because each software needs some modifications and updates from time to time. So, the design of the software should be maintainable, which can help it to bear with changes frequently.

Sometimes, it happens that after modifying the attributes of software, the other features start to misbehave and miss function. This is not a characteristic of good software.

Any change made in the software design should not feign challenges for the other features. If they pose such challenges, then the other features should be able to handle them.

Reusability

As the name suggests, reusability facilitates reusing the software to develop other software. Reusability helps the developers to create complex and advanced software using the same code in a shorter time.

The concept of reusability is already being used in several other engineering disciplines. For example, during the construction of a house, the trusses which support the roof, are reused.

The architects build a new truss for a house only if a special design is needed. In the alternative case, he or she simply reuses the existing design which earlier resonated with all the norms.

In the same way, we can reuse the software design. For example, developing an efficient sorting routine that can be integrated into various future software.

Reliability

Reliability aims at measuring the software failure where failure is defined as an unacceptable effect or behavior that adversely affects the operating conditions. To measure the software failure, the developers use the average time between failures required for repair.

To make their software reliable, software engineers want their products to adhere to the norms of high correctness and good maintainability. This means that the software should fail as little as possible and it should be as easy as possible to fix it.

The importance of reliable software quality augments in the case of real-time systems like heart monitors or air traffic control. But imagining an ideal and highly reliable system that demonstrates high correctness and good maintainability is difficult.

Portability

Portability facilitates the easy usage of the software on different computer configurations along with the one on which it is operating. Porting software is important for various reasons.

First of all, the life of good software is approximately 15 years or more. However, the life of hardware is four to five years. So, each software has to be used with three or more different hardware configurations in its lifetime.

well developed software

Secondly, porting software to a computer configuration is relatively less expensive than creating software from scratch. Thirdly, the sales of such software are augmented because of a greater target market for the software. 

The above-mentioned characteristics of software in software engineering are grouped into several headings like the operational factors, transitional factors, and maintenance factors. The operational factors help to measure the performance and the operations of software like efficiency, usability, budget, security, correctness, functionality, dependability, etc.

The transitional factors help to decide the software quality when the software is moved from one platform to another like portability, adaptability, reusability, etc.

The maintenance factors help to decide the maintainability of software regarding the dynamic trends of the environment Like modularity, maintainability, scalability, flexibility, etc. Hence, if your software resonates with the features of each group, then it is good software.
