10 Questions
What is the primary goal of the planning and requirement analysis stage in the software development life cycle?
The detailed definition of the system requirements.
What is the main difference between the system design stage and the planning stage in SDLC?
The system design stage is more detailed and technical, whereas the planning stage is more descriptive and focuses on the product requirements.
What is the primary focus of the stakeholders during the planning and requirement analysis stage?
Understanding the project from a business perspective and determining whether it's worth the investment.
What is the purpose of the requirement gathering and analysis stage in SDLC?
To clearly define the system requirements and ensure all stakeholders understand the tasks and implementation of each requirement.
In which stage of the software development life cycle do developers design the architecture of the system?
System design stage.
What is the primary task of developers during the development stage of the SDLC?
To assemble all necessary information into one working infrastructure by putting them into code.
What is the purpose of the testing phase in the SDLC?
To detect code flaws missed during development and fix them until all critical issues are removed.
What happens after the program is finalized and has no critical issues in the SDLC?
It is launched for end-users, and the tech support team joins to gather user feedback for further analysis.
What is a characteristic of the Waterfall SDLC model?
It implies strict documentation and gradual execution of every stage.
What is a key difference between the Iterative SDLC model and other SDLC models?
It does not require a complete list of requirements before the project starts.
Study Notes
Software Development Life Cycle (SDLC)
- SDLC is a continuous process that starts when a project is launched and ends when it's completely removed from exploitation.
SDLC Phases
- There are multiple SDLC models, but the sequence of phases typically remains the same.
- The phases are: Planning and Requirement Analysis, System Design, Development, Testing, and Deployment.
Planning and Requirement Analysis
- This stage involves requirement gathering and analysis, defining the system requirements in detail, and ensuring all stakeholders understand the tasks.
- The goal is to define the system requirements clearly and ensure all stakeholders are on the same page.
System Design
- This stage is an extension of the plan developed during the first phase, analyzing and systematizing gathered information.
- The design plan is amended with technical details, and the architecture is designed.
- Technical questions are discussed among stakeholders, including the customer.
Development
- This stage involves actual development, where the requirements are approved, and the necessary information is ready.
- Developers assemble the designed system into a working infrastructure by writing source code.
Testing
- This stage includes debugging, detecting code flaws, and documenting them for developers to fix.
- The testing process repeats until all critical issues are removed, and the software workflow is stable.
Deployment
- When the program is finalized, it's released to end-users.
- The tech support team gathers user feedback, consults, and supports users during exploitation.
SDLC Models
Waterfall SDLC Model
- A cascade model that presents the development process in a step-by-step flow.
- Each stage is executed gradually, with strict documentation and predefined features for each phase.
Incremental/Iterative SDLC Model
- Development can start with partial requirements, which can be expanded later.
- The process is repetitive, allowing for new product versions in each cycle.
Agile SDLC Model
- Agile is a philosophy, not a specific development approach.
- It's a family of methodologies, characterized by repetitive cycles, and flexible requirement gathering.
