Systems Development Life Cycle (SDLC)
- SDLC is a conceptual model outlining the stages of developing or altering a system.
- It defines the roles and responsibilities of team members at each phase.
- SDLC offers a clear project view and well-defined goals, allowing developers to backtrack if needed.
- Unexpected issues may complicate SDLC, and some methods lack flexibility.
- SDLC is also known as "Software" or "Application" Development Life Cycle.
SDLC Phases
- Planning defines the problem and scope and assesses project feasibility.
- Analysis involves understanding business and processing needs.
- Design defines the solution system based on requirements and analysis.
- Implementation encompasses development, testing, and deployment.
- Maintenance includes system support and enhancements.

- Project Manager: Focuses on project execution, delivery, and schedule and manages scope, timeline, and resources.
- Business Analyst: Focuses on business requirements and process analysis and translates them into functional requirements.
- Key skills for the Product Owner include communication, decision-making, and stakeholder/backlog management.
- Key skills for the Project Manager are time management, leadership, communication, and resource allocation.
- Key skills for the Business Analyst are analytical thinking, problem-solving, documentation, and process modeling.
Application Development and Software Developers
- Application Development refers to computer programming, which involves writing and maintaining source code.
- Software developers research, design, build, test, and implement software.
- Software developers build products from scratch or modify existing software using creative thinking and problem-solving skills.
- Types of developers include Application, Web, System, and Game Developers.
Qualities of a Good Software Developer
- Good developers learn new languages, rewrite old code, participate in challenges, and attend conferences.
Software Testing Explained
- Software Testing is evaluating whether a system satisfies specified requirements.
- It involves executing a system to identify gaps, errors, or missing requirements.
- Software testing analyzes software to detect differences between existing and required conditions, as well as evaluate features.
Qualities of a good software tester

Software Methodologies
- Software Methodologies are structured processes guiding software development.
- SDLC Methodologies include Agile, which uses iterations or sprints.
- The Agile methodology promotes work cycles as iterations, thus delivering functional software during the development process.
- Each cycle results in a functional software piece that can be reviewed, tested, and improved.
- Agile promotes collaboration, responds to change, and delivers frequent software updates.
- The Agile approach adapts to change through customer feedback.
Agile Development: Scrum Framework
- In Scrum, the Product Owner maintains the vision, the Scrum Master facilitates the process, and the Development Team delivers product increments.
- Epics are collections of tasks or stories.
- Stories are descriptions of features from the user’s perspective.
- A Sprint is a time-boxed period to complete epics and stories as a logical unit.
Sprints and Product Backlogs
- Sprints organize work into segments.
- The Product Backlog is a prioritized list that guides the team’s efforts.
- Sprints usually last 1-4 weeks.
- Sprint is a time-limited phase that contributes to completing the bigger Epic.
- T-shirt sizing is a project estimation technique to estimate the effort needed.
Sprint Planning and Story Points
- In Agile, Sprint Planning involves the Scrum team defining the work for the upcoming sprint.
- The team selects items from the Product Backlog for the Sprint Backlog.
- Story points measure of the effort needed to complete a task.
Stand-ups, Sprint Reviews, and Retrospectives
- Daily Stand-up meetings foster alignment and transparency among team members.
- Sprint Reviews ensures reflection and adjustment based on feedback.
- Sprint Review reviews the completed work.
- Sprint Retrospective reflects on areas for improvement.
User Stories
- Focus on the end user written from their perspective of their persona.
- User Story: Filter Products by Price Range example includes a description and acceptance criteria.
- Kanban uses a visual board to track tasks and workflow to enhance transparency.
- Kanban supports continuous delivery and promotes a steady flow of work to minimize bottlenecks.
Software Development Methodologies
- Software development uses a phased process in which each phase is completed before moving to the next phase
- Each phase of the Waterfall methodology impacts the next. The stages include requirements gathering and design specifications.
- Other stages include implementation of code, verification through testing and maintenance of the software post-deployment.
SDLC Advantages and Disadvantages
- The Waterfall method provides clear guidelines and timelines but has inflexibility.
- Environments in software development simulate stages for progression of apps.
- Development, Beta, and Production Environment are some environment examples.
Software Development Environments
- Development Environment involves code updates and commits.
- Testing Environment involves identifying and fixing bugs.
- Staging Environment involves an exact replica of production.
- Production Environment involves the code being pushed to live.
- The development environment is used to build the application and is facilitated by a Git repository.
Local vs Cloud Development Environments
- Local Development Environment is a workspace on a developer's computer where applications can be tested before code changes.
- Examples of Local Development Environment include Visual Studio Code, Eclipse, and Netbeans
- Cloud-Based Development Environment is hosted in the cloud and allows for scalability and collaboration.
- Examples of Cloud-Based Development Environment include Github Codespaces, Google Cloud Shell, and Cloud9 (AWS).
Git
- Git stores your project and saves your code versions for you to access when needed.
- Azure Repos, AWS CodeCommit, Git Hub, Bit Bucket and Git Lab, are all examples for where you can run Git
- Basic Git commands are used for branching, staging, committing, pushing/pulling and inspection
- Git Branch commands include: creates, switch, delete a feature branch
- Git Staging commands include: Stages a specific file or Stages all modified and new files
- Git Committing Changes includes: Commits staged files with a message
- Commits are pushed or pulled to other developers on your team
- Git status tracks the developers changes
Software Development Environment importance in SDLC
- Using a SDLC environment facilitates development, ensures quality assurance and supports deployment
Branch in Software Development
- A branch is where developers work on changes without affecting the main codebase.
- Branches help isolate development, test before production, have team collaboration and parallel development
Common Branch Types
- In Git Master is the production-ready branch, Develop is for ongoing development, while Feature is for new features
- The Release branch prepares code for production, and the Hotfix branch assists with urgent fixes for production
GIT Branching Strategy
- The Main Branch (Master) holds production-ready code, where the tags indicate releases
- All releases are finalized and merged into Master after tested
- Develop Branch is the integration branch and used to prepare release branches
- Feature Branches get merged on the Develop Branch
- The Hotfix Branch starts from the master branch, gets the fix applied and merged back as well for deployment.
Check in new/existing Branch
git checkout -b
creates and/or switches to a new branch- From there you write your code and # Work on code...
git checkout develop
goes back todev
branch- Finally, # To merge changes, execute
git merge feature/login-system
Github work flow
- Start with master or create/checkout a new branch
- Make code changes and commit
- Create pull request for approval
Beta Environment
- The Beta environment involves external testing to find issues not found in previous phases.
- The goal is to gauge user experience, identify defects, and validate performance.
- User feedback helps developers identify usability issues and adjust before the final launch.
Production Environment
- The Production environment is where the software becomes fully operational for users.
- It marks the end of the development lifecycle as tested and ready for operations.
Live Environment Characteristics
- These include stability and security, which are factors for Performance Optimization, all ensure long-term user satisfaction.
