Matrix GUT in Maintenance: How to Prioritize Critical Assets with More Precision

Matrix GUT is used in maintenance to prioritize assets, failures and demands. It helps answer a critical question: with so many alerts, inspections and condition data coming in, where should the team act first? What is the actual risk?

The challenge in maintenance is not just collecting condition data, but analyzing it to support decision-making and turn it into clear priorities, ones that guide planning, reduce conflicts between teams and direct resources to the assets with the greatest operational impact.

That is why Matrix GUT plays a relevant role in predictive maintenance strategies and critical asset management. By structuring decision-making, it reduces guesswork and provides a more objective basis for defining which problems demand immediate action, which can be scheduled and which should simply stay under observation.

This article explains how Matrix GUT in maintenance works, how to apply it in industrial maintenance and how the methodology connects to condition-based maintenance.

You will also see how DMA Dynamox applies the Matrix GUT concept to manage risk, making action prioritization clearer, more defensible and better aligned with the reality of each operation.

What is Matrix GUT?

Matrix GUT is a prioritization methodology used to organize problems, demands or assets according to three criteria: Gravity, Urgency and Tendency. It turns different situations into a clearer order of priority for decision-making.

Matrix GUT is a prioritization methodology used to organize problems, demands or assets according to three criteria: Gravity, Urgency and Tendency

Gravity indicates the impact of the problem, Urgency assesses the time available to act and Tendency shows the likelihood of the problem worsening over time. When the team analyzes these three factors together, it can compare different scenarios with more rigor.

Matrix GUT works well in environments where multiple demands compete for attention. Instead of setting priorities based only on the perception of the moment, the methodology provides a structure to evaluate what could generate the greatest impact, what requires a faster response and what tends to evolve if no action is taken.

What does gravity mean in Matrix GUT?

Gravity represents the impact a problem can cause if it occurs or progresses. It answers the question: “if this asset fails now, how big is the loss?”

This criterion relates directly to the consequences of a failure for the operation and for the business as a whole.

In industrial maintenance, Gravity can span several dimensions, including:

  • Impact on operations
  • Consequences for safety
  • Effects on quality
  • Environmental impact
  • Financial losses
  • Impact on company image

The greater these consequences, the higher the score assigned tends to be.

What does urgency mean in Matrix GUT?

Urgency relates to the time available to act before a problem generates more severe consequences. It indicates how fast the maintenance team’s response needs to be given a certain condition.

It answers the question: “how much time do I have to act?”

Urgency is tied to the asset’s current state. Vibration and temperature alerts, sensory inspection results, operational criticality and even the availability of maintenance windows all shape this assessment.

The less time available to intervene without risking further deterioration, the higher the score assigned should be.

What does tendency mean in Matrix GUT?

Tendency indicates the likelihood of a problem worsening over time. This criterion evaluates whether the asset’s current condition tends to progress toward a more severe failure, remain stable or, in some cases, even improve.

It can be summed up in one question: “what is the probability of this getting worse?”

In predictive maintenance, Tendency analysis becomes more precise when based on historical data and asset behavior. Vibration progression, gradual temperature increases, recurring alerts and patterns from previous failures all help determine whether a problem is intensifying.

Predictive maintenance is, in fact, built around tracking how an asset’s condition evolves over time. With monitoring data, it becomes possible to estimate when a given condition may exceed acceptable limits or how the asset is likely to behave in the near future.

This turns Tendency from a subjective perception into something grounded in concrete data, making this Matrix GUT criterion far more robust when applied on a complete platform like Dynamox’s.

How is the Matrix GUT priority index calculated?

Prioritization (or risk) under Matrix GUT comes from multiplying the scores assigned to each of the three criteria: Gravity, Urgency and Tendency. This produces the final score:

G × U × T = GUT Score

The result allows different problems, assets or demands to be compared against a common criterion, making it easier to define priorities.

The scores assigned to each dimension can vary depending on the methodology adopted by the company. Some use a 1-to-5 scale, others 1-to-10. In general, the higher the score, the greater the severity, urgency or tendency toward worsening.

What matters is not the scale itself, but consistency in applying the criteria within the same operation. After all, the goal of Matrix GUT is not to produce an absolute truth about which problem matters most, but to create a structured basis for comparing scenarios and guiding decisions.

The table below shows an example using a 1-to-5 scale for each criterion:

It is also possible to define action ranges based on the final score. On a 1-to-5 scale, for example, the lowest possible score is 1 × 1 × 1 = 1, while the highest is 5 × 5 × 5 = 125.

GUT score ranges and risk levels

Why can Matrix GUT vary between companies?

The Matrix GUT methodology stays the same, but how each company interprets the criteria can change depending on the reality of the operation. Gravity, Urgency and Tendency all depend on the context in which the asset operates.

In industrial maintenance, the same failure can have different impacts depending on the sector, the equipment’s criticality, the cost of downtime, safety risks and the team’s response capacity.

Maintenance maturity also plays a role, especially where historical data, continuous monitoring and well-structured routines are already in place.

For this reason, Matrix GUT should not be used to compare companies against each other. Its main value lies in standardizing decisions within the same operation, creating clearer criteria for what should be addressed first.

How does DMA Dynamox apply Matrix GUT in practice?

In DMA Dynamox (Decision-Making Assistant), Matrix GUT works as a prioritization layer on top of the data the platform has already analyzed. The goal is to evolve how machines and spots are organized, making it clearer which assets need attention first.

Here is how it works:

DMA ranks assets based on their GUT score, calculated from Gravity, Urgency and Tendency. This score draws on alerts from the monitoring techniques tracked on the platform, including thermometry, vibration, electrical current and other variables with available alarms.

It also factors in completed checklists, how the asset’s behavior has evolved, severity, the asset’s risk to the business and its ABC criticality classification.

Another important point: prioritization can be configured according to each customer’s parameters. Every operation can adjust its own rules and scoring based on asset criticality, operational risks and how the team works.

This gives maintenance analysts and leaders a more objective view. Instead of assessing machines and spots in isolation, the team gets a prioritized ranking connected to the operation’s real risk and to how failures are evolving.

A Practical Example of Matrix GUT in Maintenance

To see how Matrix GUT works in practice, consider two assets on the same plant floor: a main pump responsible for feeding the production line and an auxiliary fan supporting the process.

In this hypothetical case, the pump shows a progressive increase in vibration over the past few days, though it has not yet reached the most critical alert level. The auxiliary fan, meanwhile, shows a significant temperature deviation, but without meaningful progression over time.

In this scenario, the main pump receives a Gravity score of 10 due to its direct impact on production. Urgency is moderate (5), since the asset has not yet reached a critical alert level. However, a Tendency score of 9 shows continuous vibration growth, which increases the risk of the fault progressing.

The auxiliary fan, on the other hand, has lower operational impact, reflected in a Gravity score of 4. Although Urgency (8) is higher due to the significant temperature deviation, a Tendency score of 3 points to a more controlled condition, with no relevant signs of worsening in the medium term.

If the decision considered only the most severe alert at the moment, the fan might look like the priority. But by combining Gravity, Urgency and Tendency, Matrix GUT shows that the pump actually represents the greater risk to the operation. Prioritization, then, accounts for more than the asset’s current state. It also weighs its production impact and how the fault is evolving.

How Does the Matrix GUT Methodology Strengthen DMA Dynamox?

With Matrix GUT applied, DMA offers a view that is even more oriented toward prioritization. The goal is to make it easier to identify which assets need attention, based on the operation’s real risk, the equipment’s current condition and how failures are evolving.

Key advantages include:

  • GUT score applied to prioritization: monitored assets are classified according to their Gravity, Urgency and Tendency scores.
  • Asset ranking based on the GUT calculation: prioritization uses the GUT score as its central criterion, expanding DMA’s prioritization logic.
  • Prioritization defined by customer parameters: rules, weights and calculation criteria can be configured according to asset criticality, operational risks and maintenance strategy.
  • Severity metric: DMA highlights the reasoning behind each asset’s analysis, such as current severity level, proximity to critical conditions and how the failure behavior is evolving.

This way, the team interprets asset risk with more consistency, keeping the existing analytical foundation while adding a clearer layer of prioritization.

How does DMA support different maintenance profiles?

Prioritization based on Matrix GUT directly impacts different levels of the team, organizing decision-making in a clearer and more aligned way.

How different maintenance roles use DMA

Matrix GUT: Frequently Asked Questions

Does Matrix GUT replace the team’s technical analysis?

No. Matrix GUT does not replace the technical analysis of maintenance professionals, but it helps structure how demands are prioritized. The experience of analysts, technicians and engineers remains essential for interpreting symptoms, validating failure hypotheses and defining the most appropriate intervention.

What is the difference between Matrix GUT and asset criticality?

Asset criticality assesses an equipment’s structural importance to the operation, considering production impact, safety, quality and the cost of downtime, generally using an ABC criticality classification. Matrix GUT, on the other hand, is a risk-scaling prioritization methodology that also factors in the current state of the demand, evaluating the urgency of the action and the tendency of the problem to worsen.

Why should Matrix GUT be adapted to each company’s reality?

Because every operation has different assets, risks, downtime costs and response capacities. This is why the Gravity, Urgency and Tendency criteria need to reflect the reality of the plant, avoiding a generic model and keeping prioritization aligned with each asset’s real impact.
