ComparisonScaling Software Development - ZeroBlockers vs Double Diamond: Which problem-solving framework is better for you?
There is no one-size-fits-all framework for software development. Each framework covers different parts of the process in different ways. We have compiled an overview of the key features and approaches of the Double Diamond framework and ZeroBlockers to help you select the best framework for you.

- Explicit product metrics
versus
customer satisfaction as a proxy for business metrics.
ZeroBlockers unapologetically copies a lot of the solution identification and evaluation techniques from Design Thinking so there is a lot of overlap, particularly in the process, deliverables and success metrics.
But Design Thinking only goes as far as the solution identification. While these techniques definitely reduce the risk over whiteboard solutions there is still a lot of risk remaining. Until a customer has a working solution in their hand we can't know for certain whether it will be successful. ZeroBlockers includes the development phase as well as the solution phase because we will need to iterate on the solution as we build it as well.
ZeroBlockers vs Double Diamond: Approach
Feature comparison
ZeroBlockers
Effective products with empowered autonomous teams
Efficiency
- Time to Market
The time from when you identify an opportunity until the software is in place.
- Short lead time is a key metric for teams.
- Cost
The resources involved in defining solutions.
- Focus on minimising time (and cost) to market.
Double Diamond
A design framework that involves divergent and convergent thinking to explore problems and create solutions.
Efficiency
- Time to Market
The time from when you identify an opportunity until the software is in place.
- Can be quick or slow depending on implementation.
- Cost
The resources involved in defining solutions.
- Can be cheap or expensive depending on implementation.
Core Differences
Efficiency
- Time to Market
The time from when you identify an opportunity until the software is in place.
- Short lead time as a core metric
versus
implementation time left up to teams. - Cost
The resources involved in defining solutions.
- Short lead time as a core metric
versus
implementation time left up to teams.
Design Thinking is very flexible in terms of how you implement it which makes a direct comparison a bit subjective.
ZeroBlockers is more opinionated as it makes Lead Time a core metric that teams are measured on. This means that teams must come up with innovative ways to do continuous research and prototype evaluation to ensure that they balance the investment in research and risk reduction with delivery.

Effective products with empowered autonomous teams
Effectiveness
- Customer Satisfaction
How well the solutions meet the needs of the customers
- Involve users continuously to iterate and refine the software based on their feedback.
- Innovation
The level of ingenuity in the solutions that are delivered.
- Cross-functional teams, with development involvement, and a customer focus deliver better solutions.
- Business Alignment
How well the solutions align with the business goals.
- Ensures solutions are aligned with business strategic objectives.

Effectiveness
- Customer Satisfaction
How well the solutions meet the needs of the customers
- Involve users continuously to iterate and refine the problem and solution based on their feedback.
- Innovation
The level of ingenuity in the solutions that are delivered.
- A structured process involving divergent thinking to explore more and potentially better solutions and convergent thinking to select the best solution.
- Business Alignment
How well the solutions align with the business goals.
- Indirectly aligning with business goals through user satisfaction.
Core Differences
Effectiveness
- Customer Satisfaction

- Similar between frameworks.
- Innovation

- Ensure developer involvement to incorporate tech angle into solutions
versus
recommendation to involve developers. - Business Alignment
How well the solutions align with the business goals.
- Explicit business goals
versus
customer satisfaction as a proxy for business metrics.
Both frameworks identify that research and solution evaluation increases the effectiveness of the solutions we build.
The big difference is that Design Thinking only goes as far as the solution identification so there is still a lot of risk remaining. Until a customer has a working solution in their hand we can't know for certain whether it will be successful. ZeroBlockers includes the development phase as well as the solution phase because we will need to iterate on the solution as we build it as well.

Both frameworks advocate for cross-functional teams but Design Thinking stops at the solution identification stage so developers are not explicitly included. This leaves a gap in terms of identifying technical solutions to customer problems.
ZeroBlockers believes that the separation of thinkers (solution definers) and doers (developers) leads to problems because you need developers to be able to iterate quickly as feedback comes in. We don't want to introduce a sign off blocker.

Both frameworks require a large change to how companies identify the product features that they should build. ZeroBlockers is a little more complicated because it includes teams that are cross-functional across the business and IT divide as well.
While ZeroBlockers is challenging to implement you can start small - one product, one value stream. With over 10 years of UXDX content and case studies, there is also a large body of resources to assist in the rollout of the framework. The pain is worth the gain.
