Understanding Software Development Processes and Models
i. Feasibility Study: An estimate is made of whether the identified user needs may be satisfied using current software and hardware technologies. The study considers whether the proposed systems will be cost-effective from a business point of view and if it can be developed within existing budgetary constraints. A feasibility study should be relatively cheap and quick. The result should inform the decision of whether or not to go ahead with a more detailed analysis. Technical, commerce, financial,

Here are detailed answers to three of the questions:
1. Why Does Software Fail Even After Testing?
Software doesn’t physically wear out like hardware, but it can fail due to various reasons even after thorough testing. Some key reasons are:
- Incomplete Requirements: Misunderstanding or incomplete gathering of user requirements can lead to features that don’t align with user needs, causing failures in real-world scenarios.
- Changing Requirements: In agile environments, requirements often evolve. Changes

Understanding Software Architecture
Question: What is software architecture, and what purpose does it serve in development?
Answer: Software architecture involves defining the overall structure of the software, including components, their relationships, and interactions. It serves as a blueprint guiding developers to create cohesive and scalable solutions.

Software Engineering: A Layered Technology
Software Engineering is called a layered technology because it is built on a foundation with multiple layers, each supporting the one above it. The layers are:
Quality Focus (Foundation Layer):
- Ensures the process and product quality.
- Every layer depends on the focus on quality.
Process Layer:
- Acts as the framework for software development.
- Provides control and coordination for projects.
Methods Layer:
- Provides technical “how-tos” for building software.
- Includes

Software Engineering Process and Framework
Defining a Software Process
A process in software engineering is a set of organized activities for developing software, including planning, designing, coding, testing, and maintenance.
Generic Process Framework Phases
The generic process framework provides a high-level structure that can be adapted to various software development models, such as Agile, Waterfall, and V-Model. The framework is generally composed of these key phases:
Communication
This phase focuses
UI/UX Design & Web Development: Key Principles
User-Centered Design Principles
- User-centered design focuses on how users actually interact, not how designers assume they will.
- The user is not you – Real user needs must be understood through research.
Motor Laws (Human Capabilities in UI)
- Fitts’ Law – The time to reach a target depends on its distance (↑ = slow) & size (↑ = fast).
- Formula: T = D / W
- UI Tip: Make frequently used buttons larger & closer.
- Steering Law – Navigating through constrained paths slows down interaction.
- UI
