Play an AI-generated podcast conversation about this lesson

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 (correct)
The system is developed all at once and then delivered to the customer
The system is developed in a single increment with no feedback or evolution
The system is developed using the waterfall model, with strict requirements gathering upfront

What is the essence of iterative processes according to the text?

The specification is developed before the software
The specification is developed in conjunction with the software (correct)
The specification is developed separately from the software
The specification is not developed at all

What are some of the important benefits of incremental development compared to the waterfall model?

Incremental development requires more analysis and documentation than the waterfall model
Incremental development does not allow for changing customer requirements as easily as the waterfall model
Incremental development makes it harder to get customer feedback on the development work
Incremental development reduces the cost of accommodating changing customer requirements and makes it easier to get customer feedback (correct)

What is the main conflict between the incremental approach and the procurement model of many organizations?

How does the incremental development approach differ from the waterfall model in terms of changing customer requirements?

What is the main purpose of the early increments of an incrementally developed system?

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 (A) Signup and view all the answers

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 (B) Signup and view all the answers

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. (B) Signup and view all the answers

Why is incremental delivery difficult to implement for replacement systems?

Incremental delivery provides less functionality in increments compared to the system being replaced. (B) Signup and view all the answers

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. (A) Signup and view all the answers

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. (D) Signup and view all the answers

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. (A) Signup and view all the answers
