Stop Guessing. Start Prioritizing.
CUBE is a practical method for prioritizing product backlogs by examining every work item from three perspectives: Customer Value, Business Value, and Development Effort.
Does prioritizing your backlog feel like this?
Every item feels equally important. User stories, bug fixes, tech debt — they're all stacked with no clear ranking. How do you decide what matters most?
Stakeholders push their own priorities. Engineers want to fix the code. Sales wants new features. Customers want speed. Who's right?
Decisions are hard to explain or defend. You make a choice, but can you justify it to your team and stakeholders in a way that sticks?
CUBE gives you a structured, defensible method to cut through the noise.
Three perspectives. One clear priority.
CU — Customer Value
Identify user needs and gaps. Determine whether each backlog item creates real value for the people using your product. This is the "why" behind the work.
BU — Business Value
Cluster items by revenue impact, retention, and strategic goals. Keep your business interests in view alongside customer needs. Balance both to survive and grow.
DE — Development Effort
Estimate the cost of delivering each item in story-points. Find the highest-value, lowest-effort wins. Make the most of your team's capacity.

ICE prioritization targets idea banks and is suited for early-stage idea evaluation. CUBE targets product backlogs — where the work items are concrete and the goal is to maximize outcomes while using development capacity as efficiently as possible.
The Origin Story
CUBE was developed over years of real-world product management at ETAS GmbH (a 100% Bosch subsidiary), while leading the development of EHANDBOOK — a software tool for automotive engineers. EHANDBOOK won 3rd place in the automotive industry's Product of the Year 2016 award, voted by readers of Elektronik and Elektronik automotive. CUBE was not invented in a workshop. It was forged under actual prioritization pressure.

What practitioners say
"CUBE prioritization method integrates business value, customer segments, and estimation to drive more balanced and outcome-focused backlog decisions. Unlike approaches that emphasize a single dimension, it offers a more holistic view. As a result, teams can prioritize effectively and focus on what truly matters instead of optimizing in just one direction. Overall, it is making our job easier and helping us focus on the right priorities."
— Padmanabha Bhat, Senior Program Manager, Bosch Global Software Technologies
"CUBE is effective because it makes trade-offs explicit and early by evaluating items based on customer value, business value, and development effort, with a focus on the increments most likely to succeed."
— Byre Gowda, Tech Director, Bosch Global Software Technologies
"CUBE-based prioritization gave me a clear starting point for creating an initial roadmap for a completely new product we launched. It is a quick read with easy-to-understand examples. The method guides decision-making by balancing multiple dimensions, such as Kano-model-based categories, business value, and development effort."
