Course overview

Description generated based on course syllabus and open data.

A practical breakdown of complete SDLC 2025: how the software development lifecycle is applied in real IT projects, what decisions are made at each phase, and which deliverables are produced.

SDLC 2025: what the software development lifecycle includes

  • What SDLC is and how SDLC is implemented in IT projects.
  • SDLC phases: initiation, requirements analysis, design, development, testing, release, maintenance.
  • Cost and schedule estimation in SDLC: approaches, assumptions, risks.
  • SDLC deliverables and outcomes: SRS, design specs, test documentation, CI/CD pipeline, release notes, reports.
  • Best practices per phase and common pitfalls with real-life examples.
  • End-to-end SDLC case study: from idea to support with measurable quality metrics.

Who SDLC fits and when the lifecycle approach is not suitable

Suitable for

  • Analysts, project managers, developers, testers, DevOps engineers, architects.
  • Teams adopting formal SDLC phases and requiring reproducible processes and deliverables.
  • Organizations that need change control, audits, and compliance.

Not suitable if

  • The goal is a one-off prototype without maintenance or documentation.
  • No capacity to maintain minimal SDLC artifacts or quality processes.
  • Priority is rapid experimentation without traceability of decisions.

Problem → outcome in SDLC (software development lifecycle)

  • Ambiguous requirements → formalized backlog and SRS/user stories with acceptance criteria.
  • Overestimated timelines → transparent cost/scope estimates with assumptions and buffers.
  • Dev–test gap → aligned design artifacts and test cases, shift-left testing.
  • Unstable releases → CI/CD, automated quality checks, versioning and release checklists.
  • Rising maintenance costs → measurable metrics (MTTR, post-release defects), service plan.

Comparing SDLC with alternatives

  • Ad-hoc without process: fast start, low repeatability; SDLC provides phases, artifacts, and change control.
  • Pure Waterfall: strong sequencing, low flexibility; SDLC can combine iterations and increments.
  • DevOps-only focus: delivery-centric, lacks full analysis/design; SDLC spans the entire lifecycle.
  • Agile without SDLC controls: quick iterations, risk of lost traceability; SDLC adds consistent artifacts and traceability.

Outcomes after reviewing SDLC materials

  • Distinguish SDLC phases, their inputs/outputs, and roles.
  • Apply basic cost estimation and risk management practices.
  • Create a minimal artifact set (requirements, design, tests, release docs).
  • Use best practices and templates for common scenarios.
  • Reference an SDLC case study as a guide for real projects.

Course Description

This is the first ever comprehensive SDLC course that covers almost everything that anyone looking to learn and progress in software can take and become as experienced as anyone with nearly 10+ years of experience. This course is at the heart of my entire decade of experience, created in 14+ hours of content. Whatever I learn during my career about the SDLC software development lifecycle, I have included in this course. No boasting at all, Look at the curriculum of the course you will get an idea. In these 14+ hours, we're going to explore all of the following concepts from scratch with a real-life example
