Software Development Lifecycle (SDLC)

The systematic process used by software development teams to create high-quality software. It involves planning, designing, implementing, testing, deploying, and maintaining software.

Planning (SDLC)

A phase in the SDLC where the development team defines the project's goals, scope, budget, and timeline.

Design (SDLC)

A phase in the SDLC where the development team creates the software's architecture, user interface, and technical specifications.

Implementation (SDLC)

A phase in the SDLC where the development team writes the actual code for the software based on the design specifications.

What is a cost-benefit analysis in SDLC?

A cost-benefit analysis compares the potential benefits of developing a software project against the costs of developing and maintaining it. It helps determine if the project is financially viable and worth pursuing.

What is an SRS document?

The Software Requirements Specifications (SRS) document outlines the detailed requirements for the software to be developed. It serves as a blueprint for the development team.

What are HLDs and LLDs in software design?

High-Level Designs (HLDs) provide a broad overview of the software architecture and its major components, while Low-Level Designs (LLDs) delve into specific module details and implementation.

What are Automated and Manual testing?

Automated testing involves using software tools to execute tests and check for errors. Manual testing requires human testers to perform various actions and analyze results.

What are Dev, Preprod, and Prod environments?

The development, pre-production, and production environments represent different stages of software deployment. Developers work in the development environment, pre-production is for testing, and production is for actual users.

Waterfall Model

A SDLC model where each phase is completed before moving to the next, with no overlap or iteration. Think of it as building a house step by step, one phase at a time.

Agile Model

A SDLC model that emphasizes iterative development and customer feedback. It involves breaking down projects into smaller cycles, called sprints, with continuous feedback and adjustments.

V-Shaped Model

A SDLC model that focuses on verification and validation activities, with testing integrated into each phase. Think of it like a mirror image of the waterfall, with testing mirroring each development step.

Spiral Model

A SDLC model that combines elements of waterfall and prototyping, with an emphasis on risk management. It involves a series of iterative cycles, each starting with a planning phase and ending with a risk assessment.

Study Notes

Course Information

  • Course Title: Software Engineering
  • Class Year: 2024-2025

Expectations

  • Students are asked to explain their reason for enrolling in the course.
  • Students are also asked to express their expectations for the course.

Table of Contents

  • Dates and corresponding class topics are listed.

What is Software Engineering?

  • Software engineering is a branch of computer science focused on the design, development, testing, and maintenance of software applications.
  • Engineers apply engineering principles and programming languages to create software solutions for users.

Software Development Lifecycle (SDLC)

  • SDLC is a cost-effective and time-efficient process for software design and development by teams.
  • The goal is to minimize project risks and ensure the software meets customer expectations during and after production.

Software Development Lifecycle (SDLC) - Steps

  • Plan: Establishing project parameters like dimensions, costs, blueprints etc.
  • Design: Creating blueprints (blue prints), choosing styles (classic, modern) etc
  • Implement: Construction phase
  • Test: Structural and plumbing tests, handing over the unit
  • Deploy: Delivering the unit to users
  • Maintain: Maintaining the units (elevators, etc.)

SDLC - Keywords

  • Cost-benefit analysis
  • Resource allocation
  • Requirements collection
  • Best software solutions
  • Automation (and manual testing) in identifying bugs
  • Development, Pre-production, and Production environments
  • On-going support

Deliverables

  • Plan: Interviews, questionnaires, SRS (Software Requirements Specifications), HLDs, LLDs, and clickable prototypes
  • Design: Code, workable software
  • Implement: Test plans, unit tests, testing reports
  • Test: Development, pre-production and production environments
  • Deploy: Support model (priorities 1, 2, etc.)
  • Maintain: Support model (priorities 1, 2, etc.)

SDLC Models

  • Waterfall: Sequential process (Plan, Design, Implement, Test, Deploy, Maintain)
  • V-Shaped: Sequential verification and validation model often used in safety-critical applications (Aerospace, Defense)
  • Agile: (Next class topic)
  • Spiral: Iterative model (phases—Objectives Defined, Risk Analysis, Engineering, Evaluation, Planning) used for complex projects with uncertainty or high risk.
  • Other models exist

Waterfall Model - Pros and Cons

  • Pros:*
  • Easy to understand
  • Individual processing
  • Clearly defined milestones
  • Properly documented
  • Cons:*
  • No feedback paths
  • Difficult to accommodate change requests
  • No overlapping of phases
  • Limited stakeholder involvement
  • Late defect detection
  • Lengthy development cycle

Assignment

  • Electronics company needs inventory management program.
  • Daily report of sales and quantities.
  • Use Waterfall model to show development and deliverables for each phase.

V-Shaped Model (Details)

  • Sequential model (like Waterfall)
  • Each stage has a corresponding testing stage ensuring quality.
  • Often used in critical systems (aerospace, defence)
