What are the task regions in spiral model?

What are the task regions in spiral model?

Phases of Spiral Model (Tasks Regions) Customer communication tasks required establishing effective communication between developer and customer. Planning-tasks required defining resources, timelines, and other project related information. Risk analysis tasks required to assess both technical and management risks.

How many task regions are there in spiral model?

six task regions
A spiral model is divided into a number of framework activities, also called task regions. Typically, there are between three and six task regions.

What are the four 4 phases of the spiral model of development?

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 activities in each cycle of spiral process model?

Each spiral can be termed as a loop and each loop is a separate development process in a spiral model. The four activities (Planning, Risk analysis, engineering and evaluation) form the intermediary phases of a spiral model and is repeated again for each loop.

What is cohesion in SE?

Cohesion: Cohesion is a measure of the degree to which the elements of the module are functionally related. It is the degree to which all elements directed towards performing a single task are contained in the component.

What are the umbrella activities of a software process?

The umbrella activities of a software process are:

  • Software project tracking and control.
  • Risk Management.
  • Software Quality Assurance.
  • Formal Technical Reviews.
  • Software Configuration Management.
  • Work product preparation and production.
  • Reusability management, Measurement.

Which one is the most important feature of 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. The spiral model supports copying up with risks by providing the scope to build a prototype at every phase of the software development.

What is Winwin spiral model?

The Win-Win Spiral Model is a model of process based on Theory W’ which is a management theory and approach “based on making winners of all the system’s key stakeholder as necessary and sufficient for the project success.”

What is the function of spiral model?

The spiral model is a risk-driven software development process model. Based on the unique risk patterns of a given project, the spiral model guides a team to adopt elements of one or more process models, such as incremental, waterfall, or evolutionary prototyping.

What are the major activities of the spiral model of software engineering Mcq?

Explanation: planning , risk analysis ,engineering and customer evaluation are the important four major activities of the spiral model.

In which type of cohesion the sequence of activities is not important but the activities must act on the same data?

Explanation: A Module exhibits temporal cohesion when it contains tasks that are related by the fact that all tasks must be executed in the same time-span.

What is cohesion explain with example?

Cohesion means sticking together. If your group of friends heads to the lunchroom as a team and sits all together, you’re demonstrating strong cohesion. Cohesion is a word that comes to us through physics, where cohesion describes particles that are the same and tend to stick together — water molecules, for example.
