1.2.2 Systems development life cycle

• The SDLC begins with the analysis phase.
• The waterfall model is best suited for projects with uncertain requirements.

  False
• What is a key benefit of the Agile model in software development?

  High customer satisfaction
• Order the stages of the waterfall model in the correct sequence:

  1️⃣ Analysis

  2️⃣ Design

  3️⃣ Implementation

  4️⃣ Testing

  5️⃣ Deployment

  6️⃣ Maintenance
• Order the stages of the iterative model in a single cycle:

  1️⃣ Planning

  2️⃣ Design

  3️⃣ Implementation

  4️⃣ Testing
• Unlike Agile, the SDLC follows a sequential approach.
• Each SDLC model is suitable for different project scenarios.


  True
• The waterfall model is best suited for projects with well-defined, stable requirements.
• Match the SDLC model characteristic with the appropriate model:

  Sequential stages ↔️ Waterfall

  Repeated cycles ↔️ Iterative
• The waterfall model is ideal for projects with uncertain requirements.

  False
• Order the main phases of the Systems Development Life Cycle (SDLC):

  1️⃣ Analysis

  2️⃣ Design

  3️⃣ Implementation

  4️⃣ Testing

  5️⃣ Deployment

  6️⃣ Maintenance
• Match each SDLC model with its key characteristic:

  Waterfall ↔️ Sequential phases

  Agile ↔️ Iterative cycles

  Spiral ↔️ Combines risk analysis

  Prototype ↔️ Develops a model to test requirements
• The spiral model is ideal for projects with low risks and simple requirements.

  False
• What is a major limitation of the waterfall model in software development?

  Lack of flexibility
• The iterative model is well-suited for projects with uncertain or changing requirements.


  True
• The SDLC is designed to reduce risks in software development.

  True
• Order the stages of the waterfall model:

  1️⃣ Analysis

  2️⃣ Design

  3️⃣ Implementation

  4️⃣ Testing

  5️⃣ Deployment

  6️⃣ Maintenance
• What is the key characteristic of the iterative model?

  Repeated cycles
• Which SDLC model is more rigid and less adaptable?

  Waterfall
• What is the primary factor to consider when choosing an SDLC model?

  Flexibility needed
• What does the Systems Development Life Cycle (SDLC) provide for software development?

  A structured process
• Why is the Systems Development Life Cycle (SDLC) important in software development?

  It reduces complexity and risks
• The waterfall model is simple to manage because it follows sequential phases.
• Why is the prototype model useful in the SDLC?

  Refines requirements
• The iterative model involves repeated cycles of development rather than a linear sequence.
• What does the SDLC ensure in software development?

  Systematic approach
• The SDLC models balance simplicity, adaptability, and risk management.
• What makes the waterfall model less flexible for changing requirements?

  Linear structure
• The iterative model allows for more flexibility than the waterfall model.


  True
• The iterative model evolves based on user feedback.
• Match the SDLC model with its best use case:

  Waterfall ↔️ Well-defined requirements

  Iterative ↔️ Uncertain requirements
