Practical methods, proportionate evidence and clearly stated limitations. We select the approach that fits your agreed operational problem.
Back to ResourcesA WEYSENS assessment can combine OEE analysis with Lean, 5S, Kaizen and documented Gemba observations. Not every engagement includes every method. Scope, evidence requirements and deliverables are agreed before the assessment begins.
Evidence needed: Relevant production time, downtime, output, quality and reference cycle-time records.
What it can support: Where supported by consistent definitions and usable data, separate availability, performance and quality losses and show the calculation assumptions.
Limitations: An OEE result does not by itself establish root cause. Missing definitions or unreliable inputs limit what can be concluded.
Evidence needed: Agreed process descriptions, workflow steps, timing, waiting, inventory and rework records.
What it can support: Identify supported waste patterns, flow constraints and improvement priorities.
Limitations: A remote review may identify questions for further observation. It cannot verify every physical condition from records alone.
Evidence needed: Agreed workplace observations, existing checklists and relevant authorised records. Where images are needed, their purpose and secure handling must be agreed first.
What it can support: Identify evidenced organisation issues and practical actions for the agreed area.
Limitations: This is not a site-wide audit or certification. Findings are limited by the coverage, date and reliability of the supplied evidence.
Evidence needed: A defined problem, an agreed baseline, proposed or completed actions, responsible roles and follow-up measurements.
What it can support: Develop practical improvement priorities and define how progress and outcomes should be checked.
Limitations: An action plan is not proof of improvement. Before-and-after comparisons need appropriate context and comparable conditions.
Evidence needed: Dated, documented observations of the relevant process, including the operating context and who recorded them, using roles rather than unnecessary personal identifiers.
What it can support: Connect observations with operational records and highlight questions that require direct verification.
Limitations: In a remote assessment, WEYSENS reviews supplied observations. This does not imply a WEYSENS site visit or independent confirmation of every observation.
Share only authorised, minimised evidence through the agreed secure route. Findings distinguish supplied facts, assumptions, uncertainties and items requiring further verification.
It may include one or more of these methods where they are relevant to the agreed scope and supported by the evidence supplied. The written scope identifies the work included. A remote assessment does not replace an on-site inspection or guarantee savings.
