INVESTIGATION OPTIMIZER
Find the Cause. Take Action. Prevent Recurrence.
Investigation Optimizer™ is Root Cause Analysis and incident management software that helps organizations consistently report incidents, identify root causes, manage corrective actions, and prevent recurring failures. From equipment and reliability events to process, quality, and HSE incidents, investigations are centralized in one structured environment for greater visibility, accountability, and continuous improvement.
Incident Management
Corrective Action Tracking
Continuous Improvement
Is Your Investigation Process Holding You Back?
Disconnected investigations and inconsistent processes can allow failures to repeat, actions to get lost, and valuable knowledge to disappear. These six challenges may signal it's time for a more structured approach.
Recurring Failures
Problem keeps returning
Quick fixes address symptoms without eliminating the underlying cause.
Scattered Investigation Data
Knowledge is hard to find
RCA records are spread across documents, emails, spreadsheets, and systems.
Inconsistent RCA Methods
Processes vary by team
Different investigation approaches lead to inconsistent results and conclusions.
Untracked Corrective Actions
Actions lose momentum
Recommendations lack clear ownership, follow-up, and accountability.
Hidden Bad Actors
Recurring issues go unnoticed
Disconnected incident data makes chronic asset problems difficult to identify.
Limited Investigation Visibility
Priorities aren't clear
Leaders lack visibility into investigations, overdue actions, and recurring failures.
What is Investigation Optimizer?
Investigation Optimizer™ is Root Cause Analysis and incident management software designed to help organizations systematically investigate failures, identify root causes, implement corrective actions, and prevent recurrence.
It creates a centralized environment for reporting incidents, conducting structured investigations, assigning actions, tracking implementation, and preserving investigation knowledge.
Rather than treating RCA as a one-time exercise after a major failure, Investigation Optimizer helps make investigation management part of a repeatable continuous improvement process. The result is a more standardized, transparent, and scalable investigation process that helps organizations turn failures into opportunities for continuous improvement.
How Investigation Optimizer Works
Investigation Optimizer uses a structured DMAIC process to move investigations from incident identification through Root Cause Analysis, corrective action, verification, and continuous improvement.

Turn Investigation Insights Into Better Performance
Finding the root cause is only the beginning. Investigation Optimizer helps teams turn investigation findings into accountable actions, organizational learning, and measurable improvements in reliability, safety, quality, and operational performance.
Prevent Repeat Failures
Address underlying causes instead of repeatedly correcting symptoms.
Standardize RCA
Give teams a consistent, structured approach to incident investigation and problem-solving.
Increase Accountability
Assign corrective actions, establish ownership, and track progress through completion.
Improve Investigation Visibility
Give teams and leadership greater visibility into active investigations, actions, approvals, and status through centralized dashboards.
Identify Recurring Problems
Connect incidents to assets and historical investigations to expose bad actors, chronic failures, and recurring issues.
Drive Continuous Improvement
Turn investigation findings into changes that strengthen reliability, maintenance strategies, safety, quality, and operational performance.
Find the Cause. Take Action. Prevent Recurrence.
Close the Loop From Failure to Improvement
Together, the Nexus Global APM Optimizer Suite connects trusted asset data, maintenance strategy, detailed planning, failure investigation, and continuous improvement within one integrated Asset Performance Management process.
Planning Optimizer
Transforms maintenance requirements into standardized, executable job plans.
Close the Loop Between Failure and Improvement.
Investigation Optimizer connects incidents, root causes, corrective actions, and lessons learned to your maintenance strategy for lasting results.
Frequently Asked Questions About Investigation Optimizer
Investigation Optimizer™ is Root Cause Analysis (RCA) and incident management software that helps organizations report incidents, investigate failures, identify root causes, manage corrective actions, and prevent recurrence. It centralizes investigation information so teams can improve visibility, accountability, and organizational learning.
Investigation Optimizer can support investigations involving equipment failures, reliability events, process issues, quality incidents, safety concerns, HSE events, near misses, and other operational problems. This allows organizations to manage different types of investigations within a consistent framework.
Investigation Optimizer supports structured problem-solving approaches including 5 Whys, Fishbone analysis, Cause Mapping, FMEA, risk analysis, and Lean Six Sigma DMAIC. Teams can select an appropriate investigation method based on the complexity, risk, and significance of the event.
Investigation Optimizer connects incidents, root causes, corrective actions, and historical investigation knowledge in one system. This helps teams identify recurring problems and bad actors, address underlying causes, and use lessons learned to reduce the likelihood of the same failure occurring again.
Corrective actions can be assigned to responsible owners and tracked through implementation and completion. This creates greater accountability and visibility into outstanding actions, approvals, investigation status, and follow-up rather than allowing recommendations to become disconnected from the original investigation.
Yes. Incidents can be associated with the appropriate asset hierarchy, helping teams connect failure events with equipment history and identify assets experiencing recurring or chronic problems. This creates a stronger foundation for bad-actor analysis and reliability improvement.
No. Investigation Optimizer is designed to complement an organization's existing CMMS or EAM by strengthening investigation and Root Cause Analysis processes. The CMMS/EAM can remain the primary system of record while Investigation Optimizer provides the structured environment needed to investigate failures, manage corrective actions, and preserve investigation knowledge.
Investigation Optimizer helps organizations preserve lessons learned rather than allowing investigation knowledge to disappear after an RCA is closed. Findings and corrective actions can be used to improve maintenance strategies, reliability practices, work processes, safety, quality, and future decision-making.
Investigation Optimizer uses the Lean Six Sigma DMAIC framework—Define, Measure, Analyze, Improve, and Control—to provide a structured approach to incident investigation and Root Cause Analysis. The process helps teams define the problem, gather evidence, identify root causes, implement corrective actions, and verify that improvements are sustained.
Investigation Optimizer is designed for reliability engineers, maintenance and operations leaders, RCA facilitators, HSE and safety professionals, quality teams, continuous-improvement teams, and others responsible for investigating incidents and preventing recurrence.
