Cone of uncertainty

The Cone of Uncertainty is a concept used in project management to describe the amount of uncertainty surrounding the estimation of a project's completion. The cone is widest at the start of a project, when there is the most uncertainty, and narrows as the project progresses and more information becomes available.

The Cone of Uncertainty is a useful tool for project managers because it can help them to understand how much uncertainty there is surrounding a project, and how this uncertainty changes over time. It can also help project managers to communicate the amount of uncertainty to stakeholders, so that they can make informed decisions about the project.

The Cone of Uncertainty is also known as the Crystal Ball Effect.

What is the Cone of Uncertainty in agile?

The Cone of Uncertainty is a concept often used in agile software development to describe the uncertainty surrounding a project as it progresses. The cone is widest at the start of the project, when little is known about the requirements and how to achieve them, and narrows as the project progresses and more information is gathered.

The Cone of Uncertainty is a useful tool for project managers and teams to understand and manage the level of uncertainty on a project. It can help identify risks early on and track the progress of the project as it moves through the different stages.

What's one of the best way to avoid the challenges with the Cone of Uncertainty?

There is no one-size-fits-all answer to this question, as the best way to avoid the challenges associated with the Cone of Uncertainty will vary depending on the specific project and team involved. However, some tips that may help include:

- Breaking the project down into smaller, more manageable pieces
- Creating a detailed project plan with clear milestones and deliverables
- Working with a experienced and trusted software development partner
- Communicating regularly with all stakeholders to ensure everyone is on the same page

By taking these and other measures, it should be possible to avoid or at least minimize the challenges associated with the Cone of Uncertainty.

Who created the Cone of Uncertainty?

The Cone of Uncertainty was first described by Barry Boehm in his 1981 paper "Software Engineering Economics". Boehm's paper was based on his experience managing software development projects at TRW, where he observed that the amount of uncertainty about a project decreases as the project progresses. He found that the amount of uncertainty can be represented by a cone, with the widest part of the cone at the beginning of the project, and the narrowest part at the end.

Boehm's Cone of Uncertainty has been found to be a useful tool for project managers, as it can help them to plan and manage their projects effectively. It can also help developers to understand the amount of uncertainty that is inherent in any software development project, and to plan and work accordingly.

What does Cone of Uncertainty show Scrum?

The Cone of Uncertainty is a tool that can be used in Scrum to help teams visualize the amount of uncertainty that exists around a particular project or product. The cone is divided into three sections, each representing a different level of uncertainty:

1. The base of the cone represents the known knowns - these are the aspects of the project that are well understood and have little uncertainty associated with them.

2. The middle of the cone represents the known unknowns - these are the aspects of the project that are understood to some extent, but still have a significant amount of uncertainty associated with them.

3. The tip of the cone represents the unknown unknowns - these are the aspects of the project that are not well understood and have a high degree of uncertainty associated with them.

The Cone of Uncertainty can be used to help teams identify which aspects of their project are most uncertain, and thus need more attention. It can also be used to track the uncertainty level over time, to see if the team is making progress in reducing it.
