Investigate Every Failure. Prevent Repeat Events. Drive Continuous Improvement.
Transform incidents into opportunities for improvement with structured investigation management and root cause analysis. Nexus Global helps organizations eliminate recurring failures, strengthen accountability, and improve reliability through standardized processes and continuous learning.
Continuous Improvement Through Investigation
Investigation Management
A reaction to an incident, or a sustainable improvement process?
Leaders in asset intensive industries believe there is always room for improvement. Whether the trigger is an incident or near miss, knowledge of chronic issues or high cost areas of operations, Investigation Management plays a significant role.
The methods of Investigation Management range from a simple 5-Whys analysis to a more detailed and complex cause and effect approach. While most reliability engineering groups vary the technique to suit the problem, analyses generally fail due to cumbersome systems. Failure can also occur when Investigation Management knowledge is not passed on to other work sites within the company structure.
It is critical to track the implementation and the effect of a recommendation to prove the recurring problem has been eliminated or to indicate that further actions or analysis must be taken.
Nexus Global’s end-to-end approach to Investigation Management improves processes and procedures to prevent human error and equipment failure occurrence.
Investigation Management is a structured process for identifying, analyzing, correcting, and preventing problems such as equipment failures, process issues, safety incidents, quality events, and recurring operational problems. It combines incident reporting, Root Cause Analysis (RCA), corrective actions, follow-up, and organizational learning to help prevent repeat failures. Nexus Global positions Investigation Management as an ongoing improvement process rather than simply a reaction to an incident.
Root Cause Analysis is an important part of Investigation Management, but Investigation Management covers the broader process. RCA focuses on determining why an event occurred, while Investigation Management also includes incident identification, investigation selection, corrective-action development, implementation, tracking, verification, and sharing lessons learned.
Learn more about Root Cause Analysis and choosing the right investigation method.
The appropriate RCA method depends on the complexity, risk, and consequences of the problem. A relatively simple issue may be investigated using 5 Whys, while more complex events may require
Fishbone/Ishikawa analysis, Cause Mapping, FMEA, or other cause-and-effect techniques. Nexus Global's Investigation Management approach specifically emphasizes varying the investigation technique to fit the problem.
Investigation Management goes beyond identifying a root cause by ensuring corrective actions are assigned, implemented, tracked, and evaluated. Organizations need to verify that recommendations actually eliminate or reduce the problem; otherwise, additional actions or analysis may be required. This closed-loop process helps turn individual failures into opportunities for continuous improvement.
Investigation Management software can centralize incidents, investigations, corrective actions, approvals, and lessons learned instead of relying on spreadsheets, emails, or disconnected systems. Nexus Global's Investigation Optimizer™ uses a Lean Six Sigma DMAIC workflow and supports incident tracking, asset-hierarchy relationships, RCA tools, action management, dashboards, notifications, and follow-up activities.
