Questions and Answers

What is the significance of stand-up meetings in the software development process?

They facilitate monitoring and control of the development effort.

Why is it crucial to avoid skipping phases in the Software Development Life Cycle (SDLC)?

Skipping phases can lead to unclear business requirements and increased project failure.

How does finding errors early in the SDLC impact project costs?

The later an error is found, the more expensive it is to fix.

Study Notes

The Systems Development Life Cycle

The Systems Development Life Cycle (SDLC) is the comprehensive process of developing information systems, starting with planning and analysis and continuing through implementation and maintenance
SDLC phases include: Planning, Analysis, Design, Development, Testing, Implementation, and Maintenance
The SDLC planning phase establishes a high-level project plan and defines project goals
The SDLC analysis phase analyzes end-user business requirements and refines project goals into defined functions and operations of the intended system
The SDLC design phase establishes descriptions of desired features and operations of the system, including screen layouts, business rules, process diagrams, pseudo code, and other documentation
The SDLC development phase involves transforming the detailed design documents from the design phase into the actual system, including defining the programming language for development
The SDLC testing phase brings all project pieces together in a testing environment to eliminate errors, bugs, and verify the system meets the business requirements defined in the analysis phase
The SDLC implementation phase places the system into production, allowing users to perform actual business operations and includes creating user documentation highlighting how to use the system and troubleshoot problems
The SDLC maintenance phase involves performing changes, corrections, additions, and upgrades to ensure the system continues to meet its business goals

Software Development Methodologies

Software Development Methodologies include Waterfall, Agile, Rapid Application Development (RAD), Extreme Programming, Rational Unified Process (RUP), Scrum, and Business Analysis
Common reasons for software project failure include unclear or missing business requirements, skipping SDLC phases, failing to manage project scope or plan, and changing technology
Errors found later in the SDLC are more expensive to fix
