17 Questions
What is the main idea behind incremental development of software systems?
The system is developed as a series of versions, with each version adding new functionality
What is the essence of iterative processes according to the text?
The specification is developed in conjunction with the software
What are some of the important benefits of incremental development compared to the waterfall model?
Incremental development reduces the cost of accommodating changing customer requirements and makes it easier to get customer feedback
What is the main conflict between the incremental approach and the procurement model of many organizations?
There is no complete system specification until the final increment is specified
What is the purpose of exposing each increment or version of the system to the user?
To allow the user to provide feedback and help evolve the system
What type of systems are not well suited for incremental development and delivery?
Systems with all requirements analyzed upfront
What is the main reason that large customers such as government agencies may find it difficult to accommodate the new form of contract required for the incremental approach?
There is no complete system specification until the final increment
How does the incremental development approach differ from the waterfall model in terms of changing customer requirements?
Incremental development reduces the amount of analysis and documentation that needs to be redone when requirements change
What is the main purpose of the early increments of an incrementally developed system?
To implement the most important or most urgently required functionality
What is a key challenge in identifying common facilities needed by all increments in an iterative process?
Requirements are not defined in detail until an increment is implemented
What is a key advantage of the incremental approach according to the text?
It allows the specification to be developed in conjunction with the software
How does incremental development help with getting customer feedback on the system?
Customers can comment on demonstrations of the software and see how much has been implemented, which is more difficult with the waterfall model
What is the main difference between incremental development and incremental delivery?
Incremental development exposes increments to customers for comment, without delivering them, whereas incremental delivery deploys increments for use by end-users.
Why is incremental delivery difficult to implement for replacement systems?
Incremental delivery provides less functionality in increments compared to the system being replaced.
What advantage does incremental delivery offer by allowing customers to use early increments as prototypes?
Customers gain experience that informs their requirements for later system increments.
How does incremental delivery ensure that customers are less likely to encounter software failures?
By delivering the highest-priority services first and integrating them incrementally.
Why do customers not have to wait until the entire system is delivered with incremental delivery?
Because the first increment satisfies their most critical requirements so they can use the software immediately.
Learn about the concept of incremental development in software engineering, where a system is developed in a series of versions, with each version adding functionality to the previous one. Explore how this approach involves developing an initial implementation, gathering user feedback, and evolving the system through multiple iterations.
