Which one is the most important feature of spiral model?

Risk Handling in Spiral Model The most important feature of the spiral model is handling these unknown risks after the project has started. Such risk resolutions are easier done by developing a prototype.

Which is the most important feature of spiral model a quality management?

The most important feature of the model is its ability to manage unknown risks after the project has commenced; creating a prototype makes this feasible.

Which is the most important features of spiral model Mcq?

The correct option is iii. risk management.

What are the 4 phases of the spiral model?

Definition: The spiral model is similar to the incremental development for a system, with more emphasis placed on risk analysis. The spiral model has four phases: Planning, Design, Construct and Evaluation. A software project repeatedly passes through these phases in iterations (called Spirals in this model).

What are the advantages of spiral model?

Spiral Model in Software Engineering | SDLC

What is the best example of spiral model?

An example product that was built through the Spiral model is NASA's space shuttle program in the 1970s. The product was complex in nature, full of algorithms and features associated with high risk. Mainly, NASA's team used the spiral model to identify and mitigate the risk early in the product development process.

What are the features of spiral model?

The spiral model has four phases: Planning, risk analysis, product development and next phase planning or Evaluation. A software project repeatedly passes through these phases in iterations (called Spirals in this model).

What are the basic principles of spiral model?

Each trip around the spiral traverses four basic quadrants: (1) determine objectives, alternatives, and constraints of the iteration; (2) evaluate alternatives; Identify and resolve risks; (3) develop and verify deliverables from the iteration; and (4) plan the next iteration.

What is a disadvantage of the spiral development method?

Disadvantages of the Spiral Model

The Spiral Model emphasizes risk analysis and mitigation. Neglecting proper risk management can lead to issues later. Thorough documentation is time-consuming and resource-intensive, especially without proper management at the project's start.

Which is the following is the most important feature of the spiral model * 1 point efficiency management time management risk management quality management?

Answer: Risk Management is the most important feature of the spiral model. Risk management is the process of identifying the risks, assessing the risks, and controlling numerous threats to an organization's or company's capital and earnings. Explanation: 1.

Which statement is true about the spiral model?

The correct answer is option 4: In Spiral Model: the primary determinant in selecting activities in each iteration is risk.

What are the two main dimensions of the spiral model?

Answer and Explanation:

The spiral model has two dimensions namely c) radial and angular. The spiral model uses iterations with spirals.

What is the purpose of the spiral approach?

The spiral approach to teaching focuses on the open-ended nature of understanding. It demonstrates that learning never ends and is a lifelong process. Although, the spiral curriculum approach is widely considered as an appropriate approach that leads to long-term learning for the students.

Why is a spiral model more realistic?

Advantages of the Spiral Model

Estimates (i.e. budget, schedule, etc.) become more realistic as work progresses because more critical issues are discovered earlier. 2. It is more able to cope with the changes that software development entails.

What is the simplest model of SDLC?

The waterfall model is the earliest and the simplest of all the SDLC methodologies. The whole software development process is separated into phases, each phase beginning only when the previous one is completed.

What are the three 3 key principles of spiral curriculum?

Key features of the spiral curriculum based on Bruner's work are: (1) The student revisits a topic, theme or subject several times throughout their school career; (2) The complexity of the topic or theme increases with each revisit; and (3) New learning has a relationship with old learning and is put in context with ...

Which of the following is a defining feature of a spiral curriculum?

Defining Characteristics of the Spiral Curriculum

Bruner's model of the spiral curriculum is based on the following key elements (Johnston 2012): The student revisits a topic, theme, or subject several times throughout their school career. The complexity of the topic or theme increases with each revisit.

What is the spiral model also known as?

The Spiral model is also called a Meta-Model because it subsumes all the other SDLC models. For example, a single loop spiral represents the Iterative Waterfall Model. The spiral model incorporates the stepwise approach of the Classical Waterfall Model.

Is spiral model agile or waterfall?

Spiral model

For smaller projects, the Agile concept is more appropriate. This model of development combines the features of the prototyping model and the waterfall model. The spiral model was defined by Barry Boehm in his article “A Spiral Model of Software Development and Enhancement” (1985).

What is Win Win spiral model?

The WinWin spiral software engineering methodology expands the Boehm-Spiral methodology by adding a priority setting step, the WinWin process, at the beginning of each spiral cycle and by introducing intermediate goals, called anchor points. The WinWin process identifies a decision point.

Which feature of spiral approach is disadvantageous?

Spiral Model Disadvantages

The spiral model is not suited for smaller and simpler projects since it involves multiple phases. Implementing it can be complex since it involves multiple iterations of the software development process. The spiral model diagram illustrates the inclusion of several intermediate stages.

What is the main difference between the spiral model and other models?

Both the models, Waterfall model and Spiral model are used in software development. Waterfall model is also known as classical or linear model because it follows sequential stages while the spiral model does not follow the sequential stages it follows the evolutionary way.

How spiral model is different from other models?

Spiral Model vs Prototype Model

A prototype model is a software development model in which a prototype is built, tested, and then refined as per customer needs. The spiral model is a risk-driven software development model and is made with features of incremental, waterfall, or evolutionary prototyping models.

What is the most important use of the incremental model?

The main importance of the Incremental model is that it divides the software development into submodules and each submodule is developed by following the software development life cycle process SDLC like Analysis, Design, Code, and Test.
