Download this insight brief to learn how organizations can connect bowtie risk models with live operational data, helping risk officers understand which critical controls are effective or degrading, and where immediate intervention may be required.
A bowtie is only as current as the evidence behind it
Bowtie models provide a powerful way to map threats, consequences, prevention barriers, and recovery controls. However, a model produced during a workshop only reveals operational conditions and assumptions available at that point in time.
Between formal reviews, conditions can change. Inspections may be deferred, competency certifications may expire, permit deviations may accumulate, process changes may alter the operating envelope, and near misses may reveal weaknesses in critical controls.
If this operational evidence is not connected to a risk model, the bowtie may continue to show a barrier as being effective even after an underlying control has begun to degrade.
This insight brief explains how a static bowtie can become a living source of risk intelligence.
What’s inside
This insight brief examines the gap between documented barrier effectiveness and operational reality, including:
- What bowtie models assume about mechanical, procedural, and instrumented controls
- How critical-control confidence can deteriorate between formal review cycles
- Why deferred inspections, permit exceptions, process changes, and competency gaps must inform barrier status
- How operational data can update control-confidence scores
- What a live critical-control register could provide to risk officers
- How connected data supports preventative risk management and post-incident triage
- Why integrated PSM strengthens, rather than replaces, the bowtie methodology
Key takeaways
Learn how a living bowtie helps risk officers:
- Test documented control assumptions against current operational evidence
- Link mechanical-integrity inspections to relevant prevention barriers
- Flag permit-to-work variances for control review
- Reassess recovery barriers following a relevant near miss
- Identify risk pathways affected by expired contractor competencies
- Use green, amber, and red status indicators to communicate barrier confidence
- Locate similar exposures across assets, units, contractors, and risk models
- Maintain the most accurate view of organizational risk exposure
A more connected approach to critical-control assurance
This insight brief describes a living bowtie as a model whose confidence scores are updated by information from mechanical integrity, permit-to-work, incident management, PHA action tracking, contractor competency, and other operational systems.
The underlying bowtie structure remains intact. What changes is the evidence attached to each barrier, allowing the risk model to reflect current operating conditions rather than relying exclusively on assumptions captured during the original workshop.
