Diagram Industries is a website jointly run by Gwen Diagram and Ash Winter. Rather than being a standardized online course platform, it positions itself as an expert-led service provider offering speaking, consulting, training, and coaching around software testing and technical practices. The site’s content focuses on topics such as testing, quality engineering, DevOps, agile, and testability, with links to blog posts as well as book/training-related pages.
In terms of subject area, it has a fairly vertical focus: software testing, test observability/testability, quality engineering, performance engineering, build and test automation, plus agile and DevOps scenarios. The instructors’ backgrounds are the main highlight. Gwen has experience in software testing, DevOps engineering, Scrum Master work, and international speaking, and is involved in multiple testing, agile, and DevOps community activities. Ash is an independent testing consultant covering testing, performance engineering, and automation, with experience in mobile apps, web services, and test consulting teams. However, the site does not specify whether the training is delivered live, recorded, as in-person workshops, or as 1-on-1 coaching. It also does not disclose the teaching language, course syllabus, duration, assignment structure, or expected learning outcomes.
The site does not provide pricing, packages, payment methods, enterprise training quotes, or public course registration links, nor does it show any certification/certificate information. As a result, it is more likely to operate on a custom-quote basis for speaking, consulting, training, or coaching engagements, but details need to be confirmed directly. If the buyer needs budget approval, invoices, contracts, delivery scope, or post-delivery support, these should be clarified during the initial communication stage.
The strengths are that the founders’ backgrounds appear credible and strongly practice-oriented, with coverage across testing communities, conference talks, and team coaching. This makes it suitable for solving real team-level testing problems rather than simply attending a course. The downside is that the official website offers limited transparency and is not especially friendly to individual learners: it lacks a course catalog, pricing, case studies, reviews, certificates, and structured learning paths, making it hard to judge ROI directly.
Diagram Industries is better suited to software testing leads, quality engineering teams, DevOps/agile teams, and organizations that want to invite experts for internal training, workshops, consulting diagnostics, or conference talks. If you simply want to buy a structured recorded course or earn a certificate, it may not be the best match. For access from China, the site only indicates that it is powered by WordPress.com and includes YouTube links; actual website accessibility, video availability, and payment methods are not disclosed. It is advisable to prepare a proxy or alternative communication channels, and to compare it with domestic testing training providers, enterprise training vendors, or other international testing consultants.
