Software Engineering
Software Engineering is the process of software development through professionals called software engineers. Software engineering involves comprehensive engineering techniques and approaches for designing, developing, testing and maintaining of software. Software engineering is a disciplined process to ensure best quality and reliability of software. Software Engineering does not only include software development but also testing of software developed from other companies and organizations.
History of Software Engineering
History of software engineering shows that at initially developed software were not too much reliable and had many flaws. There was a need of a proper system which can produce more efficient and reliable software. Following are the major incidents in the history of software engineering.
Pre-Software Engineering Era (1940s-1960s)
[1940-1950]: Invention of electronic computers marked the foundation of pre-software engineering era. Alan Turing, Grace Hopper, and John von Neuman laid the introduced the concepts of Computing and Programming Languages.
Emergence of High-level Languages (1950-1960)
High Programming Languages such as Fortan and COBOL made the software usage and access more possible.
This was the time when developers introduced structured programming to improve code clarity.
Software Crisis and Birth of Software Engineering (1960s-1970s)
[1968]: At this time there were some flaws in software, and people started calling growing issues as “software crisis”. Developers were struggling to develop software on time and within budget.
NATO Software Engineering Conference
NATO conducted world’s first software engineering conference in 1968, and experts formally introduced the term “Software Engineering”. This conference emphasized a disciplined approach for software development which was very similar to traditional engineering. The Objective behind this approach was to address the software crisis with engineering methodologies and standards that would improve quality and project management.
Methodological Advancements (1970-1980)
[1970]: Engineers adopted Structured software development approach, which included methodologies like waterfall model, a sequential approach to development phases, requirements, design, implementation, testing and maintenance. Initially waterfall model received criticism due to rigidity but later it became a crucial model for software development.
[1980]: Developers introduced object-oriented programming with languages like Smalltalk and C++. OOP made it easier to manage complex software systems and influenced other software engineering practices.
Development of Software Engineering Models (1980-1990)
[1986]: Barry Boehm introduced the Spiral Model which was a combination of iterative model and Waterfall model to manage risks and flexibility.
[1990]: Unified language was created by developers, this language was a standard to visualize system architecture, and helped in software communication and design.
The Rise of Agile and Adaptive Methodologies (1990-2000)
[2001]: A group of developers introduced Agile Manifesto, it was a people-centered, and flexible approach which emphasized on collaboration and change. It is also considered an alternative to conventional development models. Developers introduced Agile frameworks like Scrum, Extreme Programming and Kanban which revolutionized the software engineering techniques.
DevOps Movement (Late 2000s-2010)
DevOps movement unified software development and IT operations to encourage collaboration, automation and continuous delivery. DevOps movement was aimed to shorten the development cycles and increase deployment frequency.
Modern Software Engineering (2010s- Present)
Modern Software Engineering works under the slogan of Continuous integration and Continuous Deployment. Developers are using automated coding integration, high quality development tools to ensure rapid and reliable software releases. Cloud Platforms, microservices, DevSecOps, Security Integration, Artificial Intelligence and machine learning have made the software engineering more fast paced and reliable.
