What is the importance of planning & requirement analysis phase?

Answer explanation

The planning and requirement analysis phase is crucial as it defines project scope, identifies stakeholder needs, and sets clear objectives, ensuring that the development process aligns with user expectations and reduces risks.

What is the importance of design phase?

Answer explanation

The design phase is crucial as it establishes the blueprint for the project, ensuring that all requirements are met and guiding the development process. It helps in identifying potential issues early, saving time and resources.

Which phase of the SDLC involves gathering and understanding stakeholder needs?

• Implementation

• Testing

• Requirement Analysis

• Deployment

Answer explanation

The Requirement Analysis phase focuses on gathering and understanding stakeholder needs, ensuring that the project aligns with their expectations and requirements. This is crucial for successful project development.

What is the primary goal of the Software Development Life Cycle (SDLC)?

• Produce a software that meets or exceeds customer expectations

• Maximizing profit

• Developing software as quickly as possible

• Reducing development costs

Answer explanation

The primary goal of the SDLC is to produce software that meets or exceeds customer expectations, ensuring quality and satisfaction, rather than just focusing on profit, speed, or cost reduction.

What are the popular SDLC models in industry now?

Answer explanation

Popular SDLC models include Agile, Waterfall, DevOps, and Spiral. Agile emphasizes iterative development, while Waterfall follows a linear approach. DevOps integrates development and operations for faster delivery, and Spiral combines iterative and risk-driven elements.

What is waterfall model?

Answer explanation

The waterfall model is a linear and sequential approach to software development. It consists of distinct phases: requirements, design, implementation, testing, deployment, and maintenance, where each phase must be completed before the next begins.

List TWO (2) advantages of waterfall model.

Answer explanation

Two advantages of the waterfall model are: 1) Clear structure and phases, making it easy to manage and understand the project. 2) Early detection of requirements, as each phase must be completed before moving to the next, reducing risks.

List TWO (2) disadvantages of waterfall model.

Answer explanation

Two disadvantages of the waterfall model are: 1) Inflexibility to changes, as it requires complete requirements upfront, making it hard to adapt to new information. 2) Late testing phase, which can lead to discovering issues too late in the development process.

Define Agile SDLC model.

Answer explanation

The Agile SDLC model is an iterative approach to software development that emphasizes flexibility, collaboration, and customer feedback. It involves breaking projects into smaller increments, allowing for continuous improvement and adaptation.

In agile, which TWO (2) activities are done concurrently?

• Development

• Testing

• Design

• Deploy

Answer explanation

In agile, Development and Testing occur concurrently to ensure that features are built and validated simultaneously, allowing for faster feedback and higher quality in the final product.
