Technology & Buying · Updated 23 October 2026
Write down the decision you want to improve
Before comparing devices or apps, identify the work the purchase is meant to support. An activity record, a reminder and a clinical measurement are different functions. A product that records one signal should not be assumed to diagnose a condition, recommend a medicine or replace a veterinary assessment.
Ask the supplier to state the intended use in plain language. Keep the claim beside the evidence offered for it. If a demonstration shows an attractive dashboard but does not explain what the readings mean or when they are unreliable, record that as an unanswered question.
Request evidence that fits the intended setting
Ask which species, environments and users were included in validation. Request the method, comparison standard, limitations and relevant independent work. Do not transfer a result from one device or setting to another simply because the products use similar language.
Consider the practical cost of uncertainty. Who checks an alert? How is it recorded? What happens when readings are missing or an owner changes the way the device is used? These questions help buyers understand workload without making a clinical claim about the technology.
Test the workflow with fictional information
Follow a sample record from entry to review, correction, export and closure. Include the colleagues who will use the system daily. A limited trial should have an agreed purpose, review date and stopping conditions, rather than becoming a permanent service by default.
Where information identifies clients or staff, establish the organisations’ data responsibilities and contractual arrangements. The ICO’s controller–processor guidance is a useful UK reference, and is marked as under review following the Data (Use and Access) Act. Check the current guidance when making a decision.
