Cone of Uncertainty Process Diagram Template for PowerPoint & Google Slides

Description

This editable infographic presents a gradient “cone of uncertainty” that tapers from wide (high variability) to narrow (low variability) across five project estimation phases: Phase, What, How, Do, and Deploy/Fix. Each vertical segment houses customizable text placeholders for methods and deliverables—ranging from T-shirt sizing and business requirements to source-code metrics—while a smooth red-to-purple gradient cone illustrates the shrinking estimation range over time. Color-coded bottom bars label four uncertainty levels (High, Medium, Low, Lowest) aligned beneath the corresponding columns. Built on master slides in PowerPoint and Google Slides, all shapes, connectors, and text blocks are vector-based and fully scalable. Hidden guide layers simplify adding or removing phases, swapping fills, or toggling flat vs. gradient styles. Consistent sans-serif fonts, subtle drop shadows, and ample white space ensure readability on any device, and grouped animations can introduce each phase sequentially during live presentations.

Who is it for

Project managers, scrum masters, and software estimators will leverage this template to communicate how estimation accuracy improves over development phases. Agile coaches, product owners, and stakeholders can use it to set expectations around scope definition and risk throughout a project lifecycle.

Other Uses

Repurpose this cone diagram for sales-pipeline funnels, risk-reduction roadmaps, learning-curve curves, or any scenario where variability diminishes over staged processes. Adjust labels, colors, and gradient stops to suit your narrative.
