About Diagnostic Expert
Diagnostic Expert is a small, independent business that builds Excel based industrial maintenance diagnostic tools and offers hands-on troubleshooting and reliability analysis services.
What Diagnostic Expert does
Diagnostic Expert designs Excel workbooks that turn maintenance activities, fault troubleshooting, reliability tracking, downtime Pareto analysis and FMEA/AMDEC risk scoring, into a documented, repeatable process. The tools are sold as one-time purchases on Etsy and Gumroad, with no subscription and no software to install beyond Microsoft Excel or a compatible spreadsheet program.
Alongside the products, Diagnostic Expert offers a small set of consulting and diagnostic services for teams that would rather have the analysis done directly on their own equipment and data: troubleshooting and fault analysis, root cause analysis, MTTR/MTBF and reliability analysis, maintenance KPI and downtime (Pareto) analysis, AMDEC/FMEA risk analysis, and remote technical assistance.
Background
Diagnostic Expert is built on hands-on experience in industrial and rail-sector maintenance and fault troubleshooting environments, working with electrical and industrial systems, corrective and predictive maintenance, MTTR/MTBF and KPI monitoring, and Pareto analysis. That background is reflected directly in the structure of every product: the guided checks in the Troubleshooting Diagnostic Tool, the KPI formulas in the MTTR and MTBF Calculator, and the risk scoring in the Maintenance Reliability Toolkit PRO all follow a structured, evidence-based approach to maintenance troubleshooting rather than guesswork.
Who Diagnostic Expert serves
The products and services are built for industrial electricians and technicians, maintenance and reliability engineers, maintenance managers and planners, and the apprentices and students learning the trade. Customers use the tools and services in manufacturing, rail and transportation, utilities and energy, oil and gas, and general facilities maintenance settings.
