Software engineering is defined as a process of analyzing user requirements and then designing, building, and testing software application which will satisfy those requirements.
Let’s look at the various definitions of software
- IEEE, in its standard 610.12-1990, defines software engineering as the application of a systematic, disciplined, which is a computable approach for the development, operation, and maintenance of software.
- Fritz Bauer defined it as the establishment and used standard engineering principles. It helps you to obtain, economically, software which is reliable and works efficiently on the real machines.
- Boehm defines software engineering, which involves, the practical application of scientific knowledge to the creative design and building of computer programs. It also includes associated documentation needed for developing, operating and maintaining them.
Software Engineering Is Popular
Here are important reasons behind the popularity of software engineering:
In our real life it is quite more comfortable to build a wall than a house or building. In the same manner, as the size of the software becomes large, software engineering helps you to build software.
If the software development process were based on scientific and engineering, it is easy to re-create new software with the help of software engineering.
Whenever the software process was based on scientific and engineering it is easy to re-create new software with the help of software engineering.
Hardware industry has shown its skills and huge manufacturing has lower the cost of the computer and electric hardware.
Always growing and adapting nature of the software. It depends on the environment in which the user works.
Offers better method of software development to provide quality software products.
Relationship of software engineering with other disciplines
Here, how software engineering related to other disciplines:
Gives the scientific foundation for the software as electrical engineering mainly depends on physics.
Software engineering is labor-intensive work which demands both technical and managerial control. Therefore, it is widely used in management science.
In this sector, software engineering helps you in resource estimation and cost control. Computing system must be developed, and data should be maintained regularly within a given budget.
Most software is a component of a much larger system. For example,
The software in an industry monitoring system or the flight software on an airplane. Software engineering methods should be applied to the study of this type of system.
Challenges of Software Engineering
Here are some critical challenges faced by software engineers:
- In safety-critical areas such as space, aviation, nuclear power plants, etc. the cost of software failure can be massive because lives are at risk.
- Increased market demands for fast turnaround time.
- Dealing with the increased complexity of software need for new applications.
- The diversity of software systems should be computing with each other.
Attributes of Software Products
The characteristics of any software product include features which are displayed by the product when it is installed and put in use.
They are not services which are provided by the product. Instead, they have related to the products dynamic behavior and the use of the product.
Example of attributes are:
Characteristics of Good Software
Any software should be judged by what are the methods which help you to use it.
Every software must satisfy the following attributes:
Here are some important of good software developed by software professionals
This characteristics let us know about how well software works in the operations which can be measured on:
This is an essential aspect when the software is moved from one platform to another:
This aspect talks about how well software has the capabilities to adapt itself in the quickly changing environment:
- Maintain inability
Payment For Software Engineer
The estimated total pay for a software engineer is $105,874per year in the United States Areas, with an average salary of $90,394per year, these numbers represent the median, which is the midpoint of the ranges from our proprietary total pay estimate model and based on salaries collected from our users. The estimated additional pay is $15,480per year. Additional pay could include cash bonus, commission, tips and profit sharing. The “most likely range” represents values that exist within the 25th and 75th percentile of all pay data available for this role.
Developer Salary Employment
In addition to region and education, factors such as specialty, industry and employer have an effect on a software developer’s salary. Software developers earn the highest average annual salaries working in these industries: other information services ($156,800); computer and peripheral equipment manufacturing ($152,840); independent artists, writers and performers ($150,030); scientific research and development services ($142,070); and personal care services ($40,080).
