What does SDLC stand for?

SDLC stands for Software Development Life Cycle, a structured framework guiding software projects from initial idea to deployment and maintenance, ensuring quality and meeting user needs through phases like planning, designing, coding, testing, and support. It provides a roadmap for consistency, risk reduction, and efficiency in building reliable software, with different models (like Agile or Waterfall) offering tailored approaches.

What are the 5 stages of SDLC?

The five core phases of the System Development Life Cycle (SDLC) are Planning/Analysis, Design, Development (or Implementation), Testing, and Maintenance, a structured process for creating and managing information systems, though specific models (like Agile) might group or name these slightly differently (e.g., Ideation, Development, Testing, Deployment, Operations). These stages ensure a systematic approach from initial idea to ongoing support, covering requirements gathering, building, quality assurance, and continuous improvement.
 

What are the 7 phases of SDLC?

The 7 phases of the Software Development Life Cycle (SDLC) are Planning, Analysis (Requirements), Design, Development (Coding), Testing, Deployment, and Maintenance, forming a structured process to build high-quality software from initial concept to ongoing support. Each stage builds on the last, ensuring a systematic approach to meet user needs and business goals.
 

What is the SDLC also known as?

Prescriptive techniques are referred to using various terms such as methodology, model, framework, and formal process. Other terms are used for the same concept as SDLC including software development life cycle (also SDLC), application development life cycle (ADLC), and system design life cycle (also SDLC).

What is the purpose of the SDLC?

The goal of SDLC is to minimize project risks through forward planning so that software meets customer expectations during production and beyond. This methodology outlines a series of steps that divide the software development process into tasks you can assign, complete, and measure.

What are the 7 phases of SDLC PPT?

The document outlines the 7 stages of the system development lifecycle (SDLC), which include planning, feasibility analysis, software design, programming, implementation and integration, software testing, and installation and maintenance.

What skills are needed for SDLC testing?

Candidates' coding and development skills play a crucial role in SDLC. Assessing their ability to write clean, well-structured code that adheres to coding standards is essential. Candidates should also showcase their understanding of programming languages, version control, and integration of external libraries.

Which phase of SDLC is most important?

However, if we had to choose a single most important stage, it would be system analysis and requirements. It functions as a guideline for all the following steps, helps the team become fully aware of the initial requirements, and meet or even exceed the customer's expectations.

What are the 5 principles of software development?

Understanding and applying these principles—Modularity, Abstraction, Encapsulation, Cohesion, and Coupling—will set you on a path to creating software that is not just functional but also reliable, maintainable, and scalable.

What are the 5 steps of Agile?

The five stages of the Agile SDLC are:

• Ideation: Define goals, requirements, and scope.
• Development: Build the first iteration with incremental steps.
• Testing: Ensure functionality, fix bugs, and improve quality.
• Deployment: Release the software to production.

What is L1, L2, L3, and L4 in software development?

L1 support is the first line of contact for end-users, handling basic troubleshooting and common issues. L2 support deals with more complex problems that require deeper technical knowledge. L3 support is the highest tier, involving expert engineers who tackle the most challenging and critical issues in the software.

Is SDLC 6 or 7?

The 7 phases of the Software Development Life Cycle (SDLC) are planning, feasibility analysis, system design, implementation, testing, deployment, and maintenance.

What is the role of testing in SDLC?

The testing phase in SDLC is the systematic process of evaluating software to detect defects, verify functionality, and validate that it meets specified requirements before release to production. This phase bridges the gap between development and deployment, ensuring quality and reliability.

What are the 3 C's of Agile?

In conclusion, the 3C's of Agile methodology - Collaboration, Communication, and Coordination - are essential elements that help to ensure the success of any Agile project.

What is the 3 5 3 rule in Agile?

The 3-5-3 rule in Agile, specifically for the Scrum framework, is a simple mnemonic for its core components: 3 Roles (Product Owner, Scrum Master, Developers), 5 Events (Sprint, Planning, Daily Scrum, Review, Retrospective), and 3 Artifacts (Product Backlog, Sprint Backlog, Increment). It serves as a quick checklist to ensure teams understand and implement the fundamental elements needed for transparency, inspection, and adaptation in their agile processes, making Scrum easier to grasp and apply. 

What is the 40 20 40 rule in software engineering?

The 40-20-40 rule in software engineering is a time allocation guideline for projects, suggesting 40% for planning/design, 20% for coding, and 40% for testing/deployment, emphasizing that significant effort goes into upfront design and final quality assurance, not just writing code. This contrasts with the financial "Rule of 40" for SaaS companies (growth % + profitability %), but the project-based rule highlights the importance of robust processes for successful software delivery, ensuring thorough analysis and rigorous testing, as coding itself is a smaller portion of the overall work.
