What is Delta Testing?

Delta is beta testing built on technology.

While beta is a nebulous process from the era of Waterfall development, Delta aligns with Agile and addresses modern challenges, such as diverse audiences, deeply connected products, and rapid iterative releases.

Unlike beta, Delta is scalable to cover the entire product life cycle, including many user testing scenarios: user acceptance testing, alpha testing, dogfooding, proof of concept testing, and much more.

Above all, Delta automates the tedium of user testing, producing more, higher quality results in a fraction of the time invested.

Delta Automates User Testing

Delta testing uses intelligent technology to quickly produce outstanding results with minimal time investment. Imagine: up-to-the-minute customer insights ahead of each release, regardless of how fast you're moving.

Test Planning

Planning your test or phase is as simple as sketching out what you want tested in the spreadsheet of your choice — the simpler, the better. When you're ready, just import.

Tester Recruiting

Filter for the testers you want and go — it's that easy. You can qualify targeted testers by geography, interests, experience, technology, and much more. With Centercode, surveys are as simple or powerful as you need them to be.

Activity Engagement

Dynamic surveys are generated automatically for each feature or experience being tested. Surveys assess satisfaction and drive rich, actionable feedback at the same time.

Engagement Automation

Meet Ted, an intelligent bot who continuously engages each tester based on their individual performance and behavior. As the project continues, Ted uses machine learning to adjust his strategy and tactics intuitively to reflect the areas of your product that need the most attention.

Feedback Prioritization

Feedback is automatically ranked by Impact Score, using a wide variety of signals like sentiment, frequency, severity, feature priority, tester enthusiasm, and more.

Easy Integrations

Feedback is automatically pushed to your preferred source of truth, be it Jira or whatever other systems your team relies on. Bidirectional updates allow your engineers to work in their own environment while taking action on your findings.

Traditional Testing Just Doesn't Cut It Anymore

Technology has evolved exponentially, from the way products are developed to how they're consumed — and yesterday's testing methods just can't keep up.

1. Products are becoming more...


Remember when thermostats just controlled the temperature? Products of all types are growing more complex as they seek to solve increasingly hard problems.


In order to succeed in the eyes of your customers, your products need to work with and rely on other products and configurations that you, unfortunately, have no control over.


"Fire and forget" is no longer an effective product life cycle strategy. To remain competitive in the market, you'll need to continuously update your products as your audience evolves.

2. Beyond the Product

Markets are more competitive, while audiences have become more mainstream, far less patient, and expect much more for their time and money.

3. In the End

Bringing a successful product to market is more difficult than it's ever been...
That's where delta comes in.

The Cascading Benefits of Delta Testing

Delta testing has massive and far-reaching implications for companies, their teams, their products, their customers, and you.


Conquer Markets of All Sizes

Delta testing benefits any company faced with the expanding complications that modern technology brings, from hyper-growth Silicon Valley firms born into agile environments, to the global modern enterprise coping with the challenges of an aggressive Digital Transformation.

Whatever type of technology product you're building, delta helps you navigate the complexities of modern product delivery. Even if we're talking about a cross-platform, connected product with weekly releases to several international markets — delta testing was designed to handle it all.

How Delta Testing Works

Delta tests operate in either a project or continuous fashion, based on your goals.

Centercode's Project-Based Model of Delta Testing


Cho, activities, and tester demographic and technographic requirements.


Announce test, qualify applicants, execute agreements, and distribute the product.


Testers are engaged automatically, driving Issues, Ideas, and Praise — ranked in real-time by Impact Score.


Final recommendations are made, products are returned, and incentives are distributed (if applicable).

Centercode's Continuous Model of Delta Testing


Pick the features, experiences, and activities that you'd like your testers to focus on.

Tester Replenishment

Fresh testers are added to address increasing requirements and/or offset any natural attrition.

Engagement Management

Testers are engaged by an automated agent who responds to their individual performance and behavior.

Feedback Management

Issues, Ideas, and Praise are enriched by collaboration. Results are then prioritized by Impact Score.

Results Distribution

Smart dashboards automatically summarize all results, broken down by feature and phase.
