Criticality and Maintenance Strategies

Whether your maintenance tasks are being done too often, too rarely, or without any real basis at all, Cognascents Consulting Group helps you build maintenance strategies grounded in actual equipment criticality, not habit.

When Clients Engage Us

Common reasons organizations engage criticality & maintenance strategy services

Organizations typically engage Cognascents for criticality and maintenance strategy development when they are facing:

▸Maintenance being performed too frequently, driving premature failures and wasted spend
▸No formal equipment criticality assessment in place
▸Maintenance strategies inherited from a prior owner or generic OEM recommendations
▸Resources spread evenly across assets regardless of actual risk
▸A push to reduce maintenance costs without a clear basis for where to cut
▸Preventive maintenance schedules that haven’t been revisited in years
Our Approach

Maintenance strategies matched to actual risk, not opinion.

An equipment criticality assessment (ECA), also called asset criticality ranking, scores each asset by the consequence and likelihood of its failure across safety, the environment, and production. Maintenance strategy development then assigns each significant failure mode the task that manages it, from run-to-failure to condition-based monitoring to redesign, so the most rigorous analysis goes where failure actually matters. Cognascents uses reliability-centered maintenance (RCM) principles and FMECA-based templates to get there.

Step 01

Data Collection & Analysis

Data Collection & Analysis

We gather and analyze your asset register, failure history, maintenance history, current PM schedules, and operational data to establish a solid basis for the work ahead.

Step 02

Equipment Criticality Assessment

Equipment Criticality Assessment

We conduct an ECA using your existing criticality process or help you build one, pre-assigning criticality rankings before facilitating a review workshop with your team to finalize them.

Step 03

Maintenance Strategy Development & Implementation

Maintenance Strategy Development & Implementation

We develop maintenance strategies aligned to criticality and failure modes, spanning run-to-failure, planned maintenance, predictive maintenance, condition-based maintenance, operator rounds, and re-design initiatives, then help you implement them into your computerized maintenance management system (CMMS).

Engineers Who Apply RCM Principles in Practice

Our team uses reliability-centered maintenance and FMECA-based methodology grounded in real operating experience, not a generic template applied uniformly across your asset base.

Strategies That Match the Asset, Not a One-Size-Fits-All Schedule

RISK-BASED, NOT UNIFORM
Strategies That Match the Asset, Not a One-Size-Fits-All Schedule

We tailor maintenance approaches to each asset’s criticality and failure modes, from run-to-failure to condition-based monitoring.

Criticality Rankings Your Team Actually Agrees With

COLLABORATIVE WORKSHOP APPROACH
Criticality Rankings Your Team Actually Agrees With

We pre-assign criticality rankings from your data, then facilitate a workshop so your team owns the final result rather than receiving it as an external mandate.

What You Gain

Maintenance effort spent where it actually reduces risk.

Maintenance strategy should follow risk, not the calendar. Cognascents builds strategies that put your resources where they actually matter.

REDUCED DOWNTIME

The right activity at the right time

Conducting the right maintenance activity at the right time mitigates failures and minimizes unexpected breakdowns.

PRIORITIZED RESOURCING

Resources allocated where they matter most

Criticality assessment guides resource allocation so effort goes toward maximizing reliability and performance where it counts.

ENHANCED SAFETY & COMPLIANCE

Risks mitigated proactively

Proactive maintenance strategies reduce the risks associated with equipment failures and support mechanical integrity obligations for PSM-covered equipment under OSHA 29 CFR 1910.119(j).

COST SAVINGS

Reduced downtime and optimized maintenance expense

Optimized strategies reduce downtime, maintenance expense, and extend asset lifespan.

CRITICALITY & MAINTENANCE STRATEGY QUESTIONS, ANSWERED DIRECTLY

Frequently asked questions about equipment criticality analysis

What is an equipment criticality assessment?

An equipment criticality assessment (ECA), also called asset criticality ranking, scores each asset by the consequence of its failure to safety, the environment, production, and cost, weighed against the likelihood of that failure, then sorts the asset base into criticality tiers. The tiers decide where rigorous analysis such as FMECA is warranted, where a simpler strategy is enough, and which spares deserve stocking priority in our spare parts management work.

What is the difference between RCM and FMECA?

FMECA is an analysis technique: it identifies how an item can fail, the effects of each failure mode, and ranks those modes by criticality, as described in IEC 60812. Reliability-centered maintenance (RCM) is the decision process that uses that failure-mode knowledge to select a failure management policy for each mode. SAE JA1011 sets the minimum criteria a process must meet to call itself RCM.

Is run-to-failure ever an acceptable maintenance strategy?

Yes, when a failure has no safety or environmental consequence, is evident to operators, and costs less to correct than to prevent. Run-to-failure becomes a defect when it is the default rather than a decision. A defensible strategy documents why each asset or failure mode was assigned it, so the choice survives personnel turnover and an incident review.

How does API RP 691 relate to maintenance strategy?

API RP 691, Risk-based Machinery Management, defines minimum requirements for managing health, safety, and environmental risk across the machinery life cycle. It applies only to the subset of machinery an operator screens as high-risk, not the whole asset base. A site-wide criticality assessment and the API 691 screening criteria should point to the same short list; when they disagree, one of them needs a second look.

Can a criticality-based strategy change inspection intervals for PSM-covered equipment?

It can inform them, within limits. Under 29 CFR 1910.119(j)(4)(ii) and (iii), inspection and testing of covered process equipment must follow RAGAGEP, at frequencies consistent with manufacturers’ recommendations and good engineering practice, and more frequently when operating experience warrants. A criticality ranking alone does not justify extending an interval; a documented engineering basis does.
