Q & A

What is the definition of software engineering?

Software engineering is defined as a systematic, disciplined, and cost-effective technique for software development.

What does a systematic approach in software engineering entail?

A systematic approach involves following a step-by-step methodology in software development, ensuring each phase is completed in order.

Why is discipline important in software engineering?

Discipline is important because it ensures that developers adhere to rules and maintain a consistent workflow, completing tasks within set deadlines.

How does cost-effectiveness play a role in software engineering?

Cost-effectiveness means that the techniques used in software development must operate within a budget to avoid overruns and ensure financial viability.

What are the key steps involved in the software engineering process?

The key steps include idea generation, requirements gathering, feasibility study, planning, design, implementation, testing, maintenance, and product delivery.

What was the software crisis, and why did it occur?

The software crisis occurred between 1965 and 1985 when only 2% of developed software was successfully used, primarily due to budget overruns, missed deadlines, and a lack of coherent design.

What significant change occurred in software engineering after the internet era?

After the internet era began in the 1990s, software development saw the emergence of widely-used systems like Microsoft Windows and a focus on web-based applications.

What are some current trends in software engineering?

Current trends include the integration of AI, machine learning, and deep learning, focusing on creating software that can learn and adapt independently.

How does the engineering approach differ from traditional software development methods?

The engineering approach is a comprehensive process that emphasizes systematic steps from idea generation to maintenance, unlike traditional methods that may prioritize quick delivery without thorough planning.

What is the significance of maintenance in software engineering?

Maintenance is crucial as it ensures that software remains functional, updated, and effective over time, providing ongoing support to users after the initial product delivery.
