Spiral Model 

Spiral model is one of the development process models. It is a risk-driven software development model. It has been designed while paying attention towards the unique risk patterns that are associated with a project.

The ability to deal with risk and overcome risk is the main driving force behind spiral model. Along with that, there is a high possibility to eliminate risk associated with delivering the developments in a timely manner.


There are six different invariants in the Spiral Model. It will initially define the artifacts concurrently. Then the four basic activities will be considered in every cycle. Along with that, it is possible to understand the risk and the level of effort associated. Then the anchor point milestones will be used. Then the risk can be eliminated. This will help the development teams to focus on the system and life cycle.

The biggest benefit that a scale agile team will be able to use is to reduce the risk factor associated with the developments. Then the development teams will be able to work according to their initial plans and get work done in a timely manner as planned.

In some of the instances, process that is followed to understand the risk can give life to numerous overheads. This can be a burden to the software development teams that are using the agile scrum methodologies.

If a software development team has been failing to deliver developments for several sprints, it is important to understand the reason for it and apply appropriate fixes. That’s where the spiral model will come into play and provide much-needed assistance for the agile software development team.
