A practical way of working
From a clear question to a measured next step.
A venue does not need a report full of recommendations nobody owns. It needs a clear question, a reliable starting measure, a workable option and a way to learn from what follows.
The EHS Performance Loop is a working structure. The stages used and outputs provided depend on the agreed service scope; implementation and ongoing review are not included unless agreed.
Discover → Diagnose → Design → Deploy → Demonstrate
Five stages, each with a practical purpose.
The venue is involved throughout. Not every service includes every stage; the scope determines activities, responsibilities and outputs.
01
Discover
Agree the question.
- EHS
- Clarifies the decision, scope, information needs and permissions.
- The venue
- Explains goals, service model, constraints and available records.
- Potential output
- A defined operating question and written scope.
02
Diagnose
Establish the evidence.
- EHS
- Defines measures, reviews relevant information and tests plausible explanations.
- The venue
- Confirms source definitions and explains exceptions or context.
- Potential output
- A baseline with visible assumptions, gaps and evidence confidence.
03
Design
Compare workable options.
- EHS
- Sets out options, trade-offs, effort and conditions that need to hold.
- The venue
- Assesses service impact, workload, risk and feasibility.
- Potential output
- Prioritised options, dependencies and a proposed measure.
04
Deploy
Turn decisions into routines.
- EHS
- Supports an accepted action through a tool or handover where separately scoped.
- The venue
- Approves changes, assigns owners and briefs relevant managers.
- Potential output
- An agreed action, accountable owner and implementation record.
05
Demonstrate
Review what changed.
- EHS
- Compares relevant measures on a like-for-like basis where follow-up is agreed.
- The venue
- Provides comparable information and notes other influences.
- Potential output
- A transparent follow-up finding and the next management decision.
Follow-up informs the next decision · only where agreed
The through-line
One opportunity-to-action record connects evidence with responsibility.
A typical record keeps the starting point and next step together. It is a practical management concept, not a claim of proprietary legal protection or independent certification.
- 01
Starting point
What do we know?
- Issue and question
- A reference and the operating decision being considered.
- Baseline
- Starting measure, period and denominator.
- Source
- Where the information came from and how it was defined.
- Confidence
- Evidence strength and what remains unknown.
- 02
Decision
What might change?
- Proposed action
- A practical option for management to consider.
- Mechanism
- Why it may help, with assumptions and trade-offs.
- 03
Accountability
Who owns it?
- Owner and due date
- Responsible role and an agreed timing.
- Implementation evidence
- What would demonstrate that an agreed action occurred.
- 04
Review
What changed?
- Follow-up
- Same-basis comparison, status and other influences.
Not every field is available at the start. Recording an unknown is more useful than making it look certain.
Shared responsibility
Good analysis depends on shared context.
EHS role within agreed scope
- Define measures and source limits.
- Separate observation, assumption and hypothesis.
- Explain options and implementation effort.
- Connect accepted actions to an owner and measure.
Venue role
- Authorise relevant information sharing.
- Explain context and source exceptions.
- Decide which actions are feasible.
- Support follow-up where separately agreed.
Next step
Choose a review that fits the question.
The written scope confirms whether implementation or ongoing follow-up is included.
