Independent diagnosis. Practical implementation.
LeanTrix delivers external audits for manufacturing and service companies, as well as organisations in logistics, healthcare and construction. We combine thorough diagnosis with priorities, an action plan and implementation support.
One view of the whole system
An external audit gives your organisation an independent view of how a process actually works. We review data, documentation, roles, standards and everyday practice, then bring the findings together in a coherent diagnosis. Our approach to management system auditing is guided by the ISO 19011 guidelines.
We tailor the scope to your challenge, from a single process to a comprehensive management system. Our methods include Lean Management, TWI, the Theory of Constraints, Hoshin Kanri, Toyota Kata, Six Sigma, TPM, ISO 9001 and IATF 16949, alongside requirements relating to KSC, NIS2, the AI Act and labour law.
Every audit concludes with recommendations prioritised by impact and effort, proposed KPIs and a plan for further action. Where needed, we also support a pilot, develop internal leaders and help roll out the solution.
Areas we cover
Bottlenecks, productivity, value flow, resource utilisation and pilot areas.
Work standards, job instruction, onboarding, leadership roles, skills and organisational culture.
Hoshin Kanri, TOC, KPI systems, responsibilities, Improvement Kata and change management.
Quality management systems, ISO, IATF, TPM, OEE, planned maintenance and autonomous maintenance.
KSC and NIS2 readiness, an inventory of AI applications, risks, roles and governance.
HR and payroll documentation, HR procedures, management practice and labour law risks.
Our complete offer
Each audit can be delivered on its own or combined with other areas. Below you will find every external audit available in the LeanTrix service catalogue.
At the Gemba, we check whether standards truly support safe, high-quality and repeatable work. We review job instructions, training methods, instructor and employee skills, supervision and the way standards are updated.
We map the entire process, from assessing aptitudes and planning onboarding to the Dojo, work standards, onboarding videos and measurement of retention, turnover, satisfaction and time to proficiency. We design the target Smart Onboarding process and start with the most critical area.
We identify critical equipment and bottlenecks, analyse OEE, minor stoppages and spare parts management. We assess all eight TPM pillars and plan the development of autonomous and planned maintenance, from a pilot to the entire organisation.
We diagnose why an ongoing Lean implementation has lost momentum or is failing to deliver the expected results. Using the Theory of Constraints, 4M analysis, KPIs and OCAI, we identify the transformation bottleneck, quick wins and the next steps towards a sustainable system.
We review the leader’s role, organisational structure, job instructions, teaching methods, Kaizen, job relations and safety. The audit shows whether TWI functions as a system for developing leadership skills, rather than simply a project to produce job instructions.
We assess current and preferred culture using Cameron and Quinn’s model. Together with the management team, we interpret the gaps, assess readiness for partnership and prepare a plan for changes in behaviour, relationships, leadership and management practice.
We assess the effectiveness of your quality system against ISO 9001 and IATF 16949, covering processes and risk, PFMEA, the Control Plan, MSA, SPC, audits, corrective action and practice at the workstation. The audit is delivered with expert support from QualiTeam.
We bring Hoshin Kanri strategy, the Theory of Constraints, KPIs, Lean, Kata, Six Sigma and the quality system together in one view of process management. We identify constraints, clarify responsibilities and establish an improvement rhythm supported by Coaching Kata.
We assess your organisation’s readiness for KSC and NIS2 requirements across industries, including healthcare. We map services, processes, assets, suppliers and risks, identify gaps and prepare a prioritised path towards a structured information security system.
We inventory AI systems and applications, including shadow AI, determine the organisation’s roles and risk categories, and review oversight of data, suppliers and AI use. The result is a map of obligations, AI governance priorities and an AI literacy development plan.
We independently review HR and payroll documentation, HR procedures and management practice for compliance with Polish legislation. We deliver the audit with LegalEssence and Marcelina Przykaza, combining legal and process perspectives.
We take a holistic view of strategy, flow, bottlenecks, work organisation, KPIs and the ability to implement change. We select a pilot area, prepare a plan, support implementation, develop internal leaders and help with rollout.
From diagnosis to lasting change
We adapt the process to the scope and maturity of your organisation, while maintaining one clear rhythm: PLAN–DO–CHECK–ACT.
We agree the objective, scope, key stakeholders, responsibilities and expected outcome.
We analyse data and documents, talk to your team and observe the process where the work happens.
We identify constraints, risks and quick wins, then prioritise the recommendations.
We help translate the report into standards, workshops, training and measurable actions.
We review KPIs, develop internal capabilities and scale the solution to further areas.

FAQ
If your audit spans several areas, we will build one coherent programme rather than a series of disconnected diagnoses.
An external audit is an independent assessment of a selected process, system or entire organisation, carried out by experts from outside the company. It includes reviewing data and documents, interviews, observation of practice, and a report with priorities and recommendations.
An internal audit is carried out by people within the organisation and is usually part of its ongoing assurance system. An external audit brings independence, comparison with practice in other organisations and specialist skills that the company may not maintain in-house.
When performance has stalled despite improvement efforts, before a major transformation or rollout, after requirements change, or whenever an objective diagnosis is needed. An audit is also a useful starting point for Lean, TWI, TPM, quality, cybersecurity, AI governance or HR improvement programmes.
We work primarily with manufacturing and services, as well as logistics and e-commerce, healthcare, construction and multi-site organisations. We always adapt the methodology and team to the specific industry.
We start by discussing the problem, business objective, risks and available data. Together, we then identify the sponsor, processes, locations, participant groups, assessment criteria and expected outcomes.
The duration depends on the number of processes and locations, and the level of detail required. A focused audit may take a few days, while a system-wide or multi-site diagnosis requires a phased schedule agreed after the scoping discussion.
We usually involve the sponsor, process owners, leaders and the people doing the work. Before the audit, we agree which KPIs, procedures, instructions, previous audit results and other data are needed. We request only material relevant to the agreed scope.
You receive a summary of the current state, evidence and observations, a description of risks or gaps, quick wins and a prioritised list of recommendations. Depending on the scope, we also include a roadmap, KPIs, action owners and a proposed pilot area.
Yes. We can deliver workshops, training and implementation consulting, prepare standards, develop internal leaders and instructors, review results and support rollout to further processes or locations.
A suitably scoped audit can identify gaps and help prepare your organisation for a certification audit, customer requirements or an inspection. It does not replace formal certification or a decision by the relevant authority. We always confirm the exact objective and criteria before starting.
