Characteristics of a good software

While developing a software it should meet all the required conditions such as security,speed,user features etc.Let us discuss about the required characteristics of a good software .

Characteristics that make excellent software :

1. Security :

Any software needs to be built using excellent security practices. The security is the one that proves to be the most important when it comes to a good software product. And with an increase in security threats nowadays, any software needs to gain this factor.Also, the software shouldn’t have any adverse effects on the data or hardware. The software should help a user to take proper measures to keep their data secure from external threats. 

2. User-Friendliness :

User-friendliness of good software can be defined through the user interface i.e., the smooth flow of the software design. Any software with a fantastic UI (User Interface) design is a product that’s going to get more notice than one that doesn’t.

3. Speed :

If the speed of the software you’re using isn’t sufficient, then it’s probably time for you to look elsewhere. There are many software out there that can offer the same features and still be proactive in responses and reactions.There needs to be a lightness in the actions being executed. A speedy software shows be focussed and determinant to complete tasks as demanded.

4. Efficiency :

Efficiency is essential for any piece of software to be a success. It not only needs to do the job it was built for, but it also needs to be able to offer excellent features that can help users undertake tasks quickly. Efficiency mostly relates to the way software uses accessible resources. A software with efficiency means that it deals in proper value in the time and money of the user. So when selecting a software, the process should be more clearly defined.

5. Features :

Of course, there are thousands of software products on the market that were built with simplicity in mind. The features that a software offers is the essential purpose of its existence. It should be clearly defined in the appearance, components, and capabilities to look like the best software product. 

Components of a software :

Efficiency: Efficiency is  a multifaceted quality characteristic and must be assessed with respect to a particular resource such as execution time or storage space. One measure of efficiency is the speed of a program's execution. Another measure is the amount of storage space the program requires for execution.

Maintainability: Well designed software should be flexible enough to accommodate future changes that will be needed as new requirements come to light.Quite often the programmer responsible for writing a section of code is not the one who must maintain it. For this reason, the quality of the software documentation significantly affects the maintainability of the software product.

Correctness:At the start of the software life cycle, the requirements for the software are determined and formalized in the requirements specification document. Well designed software should meet all the stated requirements. Also, it is important to remember that some products of the software life cycle such as the design specification cannot be "executed" for testing.

Reusability: By reusing existing software, developers can create more complex software in a shorter amount of time.A software can be designed to accommodate reuse in many situations. A simple example of software reuse could be the development of an efficient sorting routine that can be incorporated in many future applications.

Reliability: The frequency of software failure is measured by the average time between failures. The criticality of software failure is measured by the average time required for repair.  For some real-time systems such as air traffic control or heart monitors, reliability becomes the most important software quality characteristic. However, it would be difficult to imagine a highly reliable system that did not also demonstrate high correctness and good maintainability. Portability:  Porting software to other computer configurations is important for several reasons. porting software to a new computer configuration may be less expensive than developing analogous software from scratch. the sales of "shrink-wrapped software" can be increased because a greater market for the software is available.
