Which of the following is NOT a benefit of using a sequential lifecycle model?
- It facilitates cost estimation and control during the development process.
- It helps to track project progress through milestones and deliverables.
- It enables rapid prototyping and early user feedback. (correct)
- It allows for early testing and maintenance of the system.
Which of the following is a significant challenge associated with the sequential lifecycle model, especially in modern software development?
Which of the following is a significant challenge associated with the sequential lifecycle model, especially in modern software development?
- The excessive use of agile methodologies and iterative development practices.
- The ability to adapt to changing user needs during the development cycle.
- The lack of a clear separation between development and deployment phases.
- The difficulty in defining precise requirements early in the development process. (correct)
What is a potential consequence of 'premature freezing' in a sequential lifecycle model?
What is a potential consequence of 'premature freezing' in a sequential lifecycle model?
- A more flexible and adaptable software system.
- Increased project costs and schedule delays. (correct)
- A more efficient use of resources and time.
- Improved system security and reliability.

Flashcards
What are the main benefits of sequential lifecycle?
What are the main benefits of sequential lifecycle?
- Decomposed framework with MILESTONES and deliverables for project managers to monitor
- DELIVERABLES and their documentation allow for QA and maintenance activities throughout
- Decomposition of development process allows COSTING and CONTROL
How are deliverables in the sequential lifecycle handled?
How are deliverables in the sequential lifecycle handled?
Deliverables from each stage are used as INPUTS for the next.
What are the main downsides of sequential lifecycle?
What are the main downsides of sequential lifecycle?
- PREMATURE FREEZING is common → Problems later in lifecycle
- Lifecycle depends on CORRECT stage output
- Modern COMPLEXITY → Difficult requirements specification stage
- WORKING version not available until later in process.
What are the main challenges of sequential lifecycle?
What are the main challenges of sequential lifecycle?
- REWORK later on due to early problems
- DEADLINE incoming = cost, effort and time increase
When should you use a sequential lifecycle?
When should you use a sequential lifecycle?
- When working in domains that are WELL-understood
- Systems that require high SECURITY
Study Notes
Sequential Lifecycle Benefits
- Provides a structured framework with milestones and deliverables for project management.
- Enables quality assurance (QA) and maintenance activities throughout the project lifecycle through documented deliverables.
- Allows for cost estimation and control of the project, due to the decomposed process.
Sequential Lifecycle Downsides
- Prone to premature freezing, leading to problems later in the lifecycle.
- Success depends on the correctness of outputs generated at each stage.
- Complex projects are difficult to handle during requirements specification.
- A working version of the system is not available until later in the process.
Sequential Lifecycle Challenges
- Rework may be necessary due to inadequacies in earlier phases.
- Tight deadlines can lead to increased costs, effort, and time.
Sequential Lifecycle Use Cases
- Suitable for projects within established domains.
- Beneficial for systems requiring high security.
Sequential Lifecycle Process
- Deliverables from each stage serve as inputs for the subsequent stage.
