For a technical evaluator, a reproduced result gives a performance claim something to stand on. In a fictional choice exercise, independent verification lifts specialist preference from 40% to 54%, while trials in the buyer’s own environment lead the evidence used in recent decisions. Gather’s research with 147 US technical evaluators follows what happens around that proof, including the integration problems, costs, and maintenance demands that can derail an otherwise attractive tool.
48% put reliability among their top three outcomes.
Reliability leads the outcomes respondents want, alongside growth and employee or customer experience. In their recalled decision, security and compliance fit is the most frequently selected criterion at 44%, indicating that a technical evaluation can encompass requirements that extend well beyond the speed of delivery.
Reliability leads the desired outcomes
Which three outcomes matter most to your success over the next 12 months? Rank your top 3.
Security fit leads a broad set of decision criteria
Which three criteria most influenced that decision? Rank them in order.
Total cost and reliability also appear more often than time to value among the decision criteria, suggesting that the initial performance claim is only part of the assessment. For a supplier, that creates a reason to explain the conditions under which the tool would be operated and supported as carefully as the improvement shown in a demonstration.
A representative evaluation could explore what happens when an integration fails and which team would take responsibility for maintenance. Those are practical extensions of the criteria respondents selected, helping the evaluator examine the work adoption might create alongside the benefit the product promises.

Trials lead evidence at 35%; cost, reliability, and integration lead rejection.
A trial in the respondent’s own environment leads the evidence list, selected by 35% among the two most influential types. The reasons for rejection help explain what such a trial should examine, with cost or approval limits, unreliable behavior, and poor integration attracting almost equal shares of top-two selections.
The strongest evidence comes from trying the tool

Three practical barriers sit close together
Which two issues most often make you reject a tool that looked promising? Rank your top 2.
Only two percentage points separate those three rejection reasons. There is little to distinguish them. The more useful reading is that an evaluation needs to address financial approval alongside reliable operation and integration, because each appears frequently in the responses.
The assessment also extends into ongoing work: maintenance burden is selected by 24%, and weak documentation or support by 22%. Including those conditions in a trial would help the evaluator consider what the team would need to do after adoption, when responsibility for keeping the tool useful becomes part of the decision.

Verified performance lifts specialist preference by 13.6 points.
The fictional exercise adds a direct test of the value respondents place on verification. Specialist preference rises from 40% to 54% when an independent evaluation reproduces its claimed benefit, showing how the recommendation changes when the evidence becomes stronger. Separate variants with higher price or a longer rollout each reduce its share to 32%.

The individual responses make that increase more nuanced than the aggregate result alone suggests. Thirty-one respondents move into the specialist option after verification, while eleven move away, leaving a net increase of twenty respondents even though the added evidence does not produce the same response from everyone.
For a vendor designing an evaluation, making the result inspectable means stating the starting conditions and the work used to measure the change, so colleagues who were absent from the test can judge whether it resembles the conditions in which their own team would use the tool.
“Decisions were driven by balancing cost, implementation time and efficiency gains. A recommendation would be reversed if cost increases or timeline extensions outweigh the performance benefits.”Staff, principal, or senior engineer · Healthcare or life sciences
38% authorize bounded code generation; 30% authorize bounded deployment.
Routine AI use reaches 78% among these respondents, who then distinguish between the automated actions they would permit under current controls. Human approval before each action is the most common choice for merging code and for deployment, even though AI use is already part of daily work for most of the sample.
Routine AI use is common
Where is your team today with using AI tools in its own work?
Technical: permission changes with the action
For each of these tasks, what's the highest level of automation you'd authorize today under your organization's current controls?
Generate a code change
Merge a change into the main codebase
Deploy a change to production
For code generation, the shares choosing approval before each action and production within approved limits are equal at 38%. Merging and deployment shift toward explicit approval, suggesting that evaluators distinguish between producing an artifact and authorizing the step that carries it into the workflow.
A product demonstration can preserve that distinction by showing how a proposed change is reviewed, and what must happen before it is released. That would let the evaluator examine the points at which responsibility passes between the system and the team, rather than inferring the approval model from the presence of an AI feature.

81% describe a decision with multiple sign-offs.
The evidence gathered during evaluation often serves a shared approval process, with 49% of respondents reporting two or three sign-offs and 32% reporting four or more. A technical recommendation therefore needs to convey what the test established to people who may not have participated in running it.
Where the recent decision ended
What did your organization ultimately do?
How many people signed off
Counting yourself, how many people had to sign off before that decision was final?
How long the decision took
From the first serious look to a final decision, roughly how long did that decision take?
The alternatives under consideration are also broad, spanning a new commercial purchase or supplier expansion, internal development, and open source. Half of the recalled decisions ended in a commercial purchase or an expansion or renewal, leaving a substantial share in which respondents pursued another route or continued with evaluation or the current approach.
Seventy-one percent report that the recalled decision took no more than three months, although those decisions cover different categories and outcomes. Preparing a clear account of the test while evaluation is underway would help colleagues assess the result without having to reconstruct how it was obtained.
65% use analysts. Cost is the leading message, by a narrow margin.
Industry analysts are the most widely used evaluation source at 65%, followed by colleagues on other internal teams and vendor content. Online communities are consulted by a smaller share, suggesting that a plan to reach technical evaluators should account for formal research and internal discussion alongside community participation.
Where respondents look for information
When you're evaluating a new technology, which of these sources do you actually rely on?
Which promise earns a closer look
Which of these messages would most likely earn a closer look from you for a tool in the category you described?
A message about lower ongoing costs earns a closer look from 37%, leading the messages tested, although less manual effort and more predictable work also attract substantial shares. The spread gives suppliers a reason to test the opening emphasis with their own audience while keeping the underlying proposition consistent across those benefits.
The earlier evidence findings show how that initial interest can develop into an evaluation: analysts help respondents research their options, while trials in their own environment lead the evidence they found influential. Linking discovery material to a practical test would make it easier to examine whether the advertised benefit applies to the team’s work.
