Lean management and Lean Six Sigma have become standards of continuous improvement in much of Swiss organisations, from industrial sectors to IT services. Lean approaches structure process analysis, waste reduction, performance measurement and team engagement around a sustainable improvement approach. In Geneva, Lausanne and across French-speaking Switzerland, banks, insurance companies, international organisations, hospitals, industries and public services integrate these frameworks into their transformation programmes.
Following a recognised Lean training opens access to key roles in continuous improvement: Lean coach, operational excellence manager, continuous improvement engineer, transformation project manager, quality officer. The Lean Six Sigma certifications (Yellow Belt, Green Belt, Black Belt) and Lean IT are internationally recognised and provide a common framework to teams. Investing in a Lean certification enhances your profile in a segment where demand is steadily growing among major Swiss employers.
ITTA offers a catalogue dedicated to processes and Lean management, from Yellow Belt level to Black Belt Lean Six Sigma. Each session is built around practical cases inspired by the daily work of Swiss companies, with limited group sizes to enable personalised support and individual feedback on your own improvement projects.
Whether you are a manager, quality officer, project manager, engineer, consultant or CIO, our training in Geneva and Lausanne provides the methods to structure a continuous improvement approach, measure process performance and support your teams in a sustainable transformation.
The Lean IT training applies Lean principles to information system departments: ticket flow analysis, demand management, service performance measurement, waste elimination and continuous improvement. The programme prepares for the internationally recognised Lean IT Foundation certification by APMG. The Lean IT Kaizen training deepens the facilitation of continuous improvement workshops (Kaizen events) in IT teams, particularly useful for IT Lean coaches, quality officers and digital transformation project managers.
The Lean Management training covers the structuring principles of Lean at organisational level: Value Stream Mapping, 5S, visual Kanban, visual management, short interval animations, structured problem solving (PDCA, A3, 5 Whys). This training suits team managers, quality officers, project managers and executives wishing to drive a Lean approach within their direction. The programme suits all sectors (industry, services, administration, IT) and does not require technical prerequisites.
The Yellow Belt Lean Six Sigma training constitutes the first level of the Six Sigma framework. The programme covers the DMAIC approach (Define, Measure, Analyse, Improve, Control), basic statistical tools, process mapping and team problem solving. This training suits contributors in improvement projects, operators, technicians, quality officers and all profiles joining a Lean Six Sigma team without advanced statistical prerequisites.
The Green Belt Lean Six Sigma training deepens statistical tools (control charts, simple design of experiments, process capability) and autonomous improvement project management. The programme targets project managers, quality officers and continuous improvement engineers driving DMAIC projects over 4 to 6 months. The Green Belt certification is internationally recognised and constitutes a major step in an operational excellence career.
The Black Belt Lean Six Sigma training targets expert profiles driving large-scale improvement programmes and supporting Green Belts. The programme deepens advanced statistical tools (complex design of experiments, ANOVA, regression, Monte-Carlo simulation), change management, team coaching and the deployment of a Lean culture in an organisation. The Black Belt certification is expected from operational excellence programme managers, senior consultants and quality directors.
A contributor or operator starts with Yellow Belt Lean Six Sigma to acquire the framework basics. An IT manager or IT quality officer follows Lean IT then Lean IT Kaizen to structure their approach in an information system direction. A general manager follows Lean Management then Yellow Belt Lean Six Sigma to combine both frameworks. A project manager or continuous improvement engineer progresses to Green Belt after Yellow Belt. A programme manager or senior consultant targets Black Belt after Green Belt. Our pedagogical team guides you towards the sequence suited to your role and current level.
Here is a selection of reference training courses in this catalogue, accessible directly:
Lean management fits into a broader ecosystem of IT, project and quality steering. Agile and Scrum training brings a complementary product framework with PSM, PSPO and SAFe certifications, particularly useful in development teams. The IT service management sub-domain covers ITIL 4, fundamental to articulate Lean IT and service operations. Project management training brings Prince2 and PMP methods. The managerial DevOps sub-domain structures the continuous delivery culture, highly compatible with Lean IT. On the human side, team and people management training reinforces the managerial skills needed to sustain a Lean approach over time.
Several evolutions are shaping Lean management in 2026. Process digitalisation accelerates the combination between Lean and automation (Power Automate, RPA, AI agents), with Lean projects now leading to fast automations. Lean IT integrates with DevOps and SRE approaches, particularly on service performance measurement and ticket flow waste reduction. DORA indicators (lead time, deployment frequency, change failure rate, mean time to restore) echo classic Lean indicators. Mastery of data visualisation via Power BI or Looker Studio becomes a natural complement to drive a Lean approach. Our pedagogical content regularly integrates these evolutions to remain aligned with current company practices.
All our Lean management and Lean Six Sigma training courses are available on-site in our Geneva (Route des Jeunes 35) and Lausanne (Avenue de Mon-Repos 24) centres, as well as in interactive virtual classroom with a live trainer. Our sessions are organised in 5-week cycles, which makes registration fast and planning smooth for working managers. Each session includes practical cases and workshops, particularly rich on Green and Black Belt levels. Customised corporate training is also possible at your premises, in Geneva, Lausanne, Vaud and across French-speaking Switzerland, with a programme adapted to your industry and Lean maturity. Several professional funding paths can be considered depending on your profile and employer.
ITTA is a certified training centre based in French-speaking Switzerland, official partner of APMG and Lean Six Sigma Institute. Our Lean trainers are Black Belts and consultants active in operational excellence projects for Swiss and international companies, allowing them to share current concrete cases and indicators actually used in steering committees. The catalogue regroups our training courses covering the Lean IT, Lean Management certifications and the Lean Six Sigma belts. Our pedagogical team supports you in choosing the right path, preparing the exams and identifying the funding solutions that fit your professional situation.
What is the difference between Lean Management and Lean Six Sigma?
Lean Management focuses on waste elimination, visual management and daily continuous improvement, without statistical prerequisites. Lean Six Sigma combines Lean philosophy with a structured statistical approach (DMAIC) to reduce process variability. Both approaches are complementary and often followed successively by continuous improvement profiles.
Is prior training required before Yellow Belt Lean Six Sigma?
No. The Yellow Belt Lean Six Sigma training is accessible to contributors and operators without statistical prerequisites. It lays the common vocabulary, the DMAIC approach and the basic tools. Profiles wishing to then drive Six Sigma projects autonomously progress to Green Belt.
Is the Black Belt certification suited to a consultant?
Yes. Black Belt Lean Six Sigma targets experts driving large-scale improvement programmes and supporting Green Belts. This certification is highly valued by operational excellence recruiters, particularly in IT services companies, consulting firms and quality directions of large companies.
Are your Lean courses available for companies?
Yes, the entire Lean catalogue is available in-house, in Geneva, Lausanne and in virtual classroom, with a programme adapted to your industry and Lean maturity. Our team builds the specifications with you and organises sessions according to your calendar.
