Planning phase Establishes a high-level plan of the intended project and determines project goals
Analysis phase Involves analyzing end-user business requirements and refining project goals into defined functions and operations of the intended system
Business requirement Specific business requests the system must meet to be successful
Design phase Establishes descriptions of the desired features and operations of the system including screen layouts, business rules, process diagrams, pseudo code, and other documentation
Development phase Involves taking all of the detailed design documents from the design phase and transforming them into the actual system
Testing phase Involves bringing all the project pieces together into a special testing environment to eliminate errors and bugs, and verify that the system meets all of the business requirements defined in the analysis phase
Implementation phase Involves placing the system into production so users can begin to perform actual business operations with it
Maintenance phase Involves performing changes, corrections, additions, and upgrades to ensure the system continues to meet its business goals

Prototype A smaller-scale representation or working model of the users’ requirements or a proposed design for an information system The prototype is an essential part of the analysis phase when using a RAD methodology
Extreme programming (XP) methodology Breaks a project into tiny phases, and developers cannot continue on to the next phase until the first phase is complete
Rational Unified Process (RUP) Provides a framework for breaking down the development of software into four gates Gate One: Inception Gate Two: Elaboration Gate Three: Construction Gate Four: Transition
SCRUM Uses small teams to produce small pieces of deliverable software using sprints, or 30-day intervals, to achieve an appointed goal Under this methodology, each day ends or begins with a stand-up meeting to monitor and control the development effort
Primary reasons for project failure Unclear or missing business requirements Skipping SDLC phases Failure to manage project scope -Scope creep -Feature creep Failure to manage project plan Changing technology
