Q1. Explain the principles and objectives of Software Engineering and discuss the major phases of the software engineering process. 5+5  

Ans 1.

Principles and Objectives of Software Engineering & Major Phases of the Software Engineering Process

Software Engineering is a disciplined field concerned with the systematic development, operation, and maintenance of software systems. Its primary purpose is to provide structured, predictable, and measurable approaches to building software that meets user expectations while minimizing errors, costs, and delays. As software complexity continues to rise, the principles and objectives of software engineering help ensure reliability, scalability, and long-term maintainability.

Principles of Software Engineering

Software engineering is guided by several principles that promote quality and efficiency. One

Q2. Compare the Prototyping Model, Agile Model, and V-Model in terms of process flow, advantages, and limitations. 10

Ans 2.

Comparison of Prototyping Model, Agile Model, and V-Model

Software development models provide structured approaches to managing and organizing project activities. Each model has its own strengths, limitations, and suitability depending on project size, clarity of requirements, and customer involvement. The Prototyping Model, Agile Model, and V-Model are three widely used methodologies that differ significantly in process flow, flexibility, and emphasis.

Prototyping Model

The Prototyping Model begins by building a working prototype that demonstrates system

 

Q3. Differentiate between functional and non-functional requirements and explain how software requirements are documented. 5+5

Ans 3.

Functional vs Non-Functional Requirements & Documentation of Software Requirements

Requirements engineering is one of the most critical phases of software development because it serves as the foundation for design, implementation, and testing. Requirements are broadly divided into functional and non-functional categories. Both play distinct roles and must be properly documented to ensure that the development team builds a system aligned with user expectations.

Functional Requirements

Functional requirements define what a system should do. They describe system behaviors,

Q4. Describe the Object-Oriented Design process and explain how object identification and design models support software development. 5+5

Ans 4.

Object-Oriented Design Process & Role of Object Identification and Design Models

Object-Oriented Design (OOD) is a structured method of creating software by organizing it around objects rather than functions or procedures. It focuses on representing real-world entities as classes, defining their behaviors, and establishing meaningful interactions among them. OOD supports modularity, reusability, and maintainability, which are central to modern software engineering. The design process includes multiple steps such as identifying objects, defining

 

 

Q5. Explain different types of software maintenance and discuss software re-engineering and configuration management processes. 5+5

Ans 5.

Types of Software Maintenance, Software Re-Engineering & Configuration Management

Software maintenance is a vital activity that begins after software deployment and continues throughout its lifecycle. It ensures that the software remains functional, efficient, and aligned with evolving user needs. Alongside maintenance, software re-engineering and configuration management help improve system quality and maintain control over software versions and modifications.

Types of Software Maintenance

Software maintenance can be broadly classified into four categories. The first is Corrective

 

Q6. Discuss various software quality metrics and explain how metrics are applied to analysis, design, code, testing, and maintenance models. 5+5        

Ans 6.

Software Quality Metrics & Their Application to Analysis, Design, Code, Testing, and Maintenance

Software quality metrics provide measurable indicators that help evaluate the effectiveness, reliability, and maintainability of software throughout its lifecycle. Metrics offer objective insights into different phases such as analysis, design, coding, testing, and maintenance, enabling teams to monitor progress, identify weaknesses, and take corrective actions based on quantifiable data.

Quality Metrics Overview

Software quality metrics can be broadly classified into product metrics, process metrics, and
