A Review of Fundamentals of Software Engineering by Rajib Mall
Fundamentals of Software Engineering is a textbook written by Rajib Mall, a professor of computer science and engineering at IIT Kharagpur. The book covers various topics related to software engineering, such as software life cycle models, software project management, requirements analysis and specification, software design, coding and testing, software reliability and quality management, computer aided software engineering, software maintenance, software reuse and emerging trends. The book is intended for undergraduate and postgraduate students of computer science and engineering, as well as for software practitioners who want to learn the fundamentals of software engineering.
The book is divided into 15 chapters, each with a clear introduction, objectives, summary and review questions. The book also provides a large number of worked-out examples and practice problems to help students understand the concepts and apply them to practical software assignments. The book uses UML (Unified Modeling Language) for object-oriented software development and provides case studies to illustrate the use of various software engineering techniques and tools. The book also discusses the latest developments in software engineering, such as agile development using SCRUM, MC/DC testing, quality models and more.
The book is well-written and easy to follow, with a logical organisation and a consistent style. The book provides a comprehensive and balanced coverage of both theory and practice of software engineering. The book is suitable for both beginners and advanced learners of software engineering, as it covers both the basics and the advanced topics in depth. The book is also useful for software professionals who want to update their knowledge and skills in software engineering.
The book is available online in PDF format from various sources[^1^] [^2^] [^3^]. The book can also be purchased from online or offline bookstores. The book has received positive reviews from students and teachers who have used it as a textbook or a reference book for software engineering courses.
In this article, we will review some of the key concepts and topics covered in the book Fundamentals of Software Engineering by Rajib Mall. We will also provide some examples and exercises to help you test your understanding of the material.
Software Life Cycle Models
A software life cycle model is a framework that describes the phases, activities and deliverables involved in software development. There are various types of software life cycle models, such as waterfall model, incremental model, spiral model, prototyping model, agile model and more. Each model has its own advantages and disadvantages, depending on the nature, size and complexity of the software project. The book explains the characteristics, benefits and limitations of each model and provides guidelines for choosing the most appropriate model for a given software project.
Example
Consider a software project to develop an online shopping system for a large e-commerce company. The system should allow customers to browse products, add them to a shopping cart, check out using various payment methods, track their orders and provide feedback. The system should also support inventory management, order processing, delivery management and customer service for the company. The system should be reliable, secure, scalable and user-friendly.
Which software life cycle model would you choose for this project and why
Solution
One possible choice is the agile model, which is a flexible and iterative approach to software development. The agile model allows for frequent feedback from customers and stakeholders, early delivery of working software, adaptation to changing requirements and continuous improvement of quality. The agile model is suitable for complex and dynamic software projects that involve high uncertainty and risk. The agile model can also cope with the competitive and fast-changing nature of the e-commerce domain.
Another possible choice is the incremental model, which is a linear approach that divides the software project into smaller and manageable modules. The incremental model delivers each module as a separate product with its own requirements, design, coding, testing and deployment. The incremental model allows for early validation of functionality, gradual integration of modules, parallel development of modules and better control of cost and schedule. The incremental model is suitable for large and well-defined software projects that involve low uncertainty and risk. The incremental model can also accommodate some changes in requirements during the development process.
Software Project Management
Software project management is the process of planning, organising, directing and controlling the resources and activities involved in software development. Software project management involves various tasks such as project initiation, project planning, project execution, project monitoring and control, project closure and more. Software project management also involves various techniques such as feasibility analysis, risk analysis, estimation techniques, scheduling techniques, quality assurance techniques and more. The book describes the principles and practices of software project management and provides tools and methods for effective software project management.
Example
Consider a software project to develop a mobile game app for children aged 6 to 10 years. The app should provide various educational games that teach children basic math skills such as addition, subtraction, multiplication and division. The app should also provide feedback on the children's performance and progress. The app should be fun, interactive and engaging for the children.
How would you estimate the effort required for this project
Solution
One possible technique is the function point analysis (FPA), which is a method that measures the size of a software product based on its functionality. FPA involves identifying the functional requirements of the software product and assigning them weights based on their complexity. FPA then calculates the total function points (FP) by summing up the weighted functional requirements. FPA then converts the FP into effort (in person-months) by multiplying it with a productivity factor (PF), which depends on various factors such as technology level, team experience, development environment and more.
Another possible technique is the analogy method, which is a method that estimates the effort required for a new software project based on the effort required for similar past projects. Analogy method involves finding one or more past projects that are similar to the new project in terms of functionality, size, complexity and domain. Analogy method then adjusts the effort required for the past projects based on the differences between them and the new project. Analogy method then averages or interpolates the adjusted efforts to obtain an estimate for the new project. aa16f39245
