Sigma Quality Consultancy

Experts in guiding organizations to solve constraints

TJ at a workshopOur believe is that any organization, whether small or big, can be transformed to a better functioning workplace that will improve customer relationships, employee happiness and financial performance.

Over the past 20 years we have been successfully guiding clients to identify constraints in their organizations and solve them by implementing lasting solutions.

A partner to improve the performance of your organization

Our purpose is to support and guide your organization in solving these challenges:

    • Constraints in your processes and organization leading to loss of sales opportunities, slow time to market launches, long delivery lead times and slow responses to customer inquiries
    • Low engagement of staff: lack of motivation, initiative and empowerment
    • Making your strategy work: Implement strategies and initiatives successfully  (e.g. get buy-in from all stakeholders, finish what you have started)

Our industry experience encompasses a broad range, to name a few: automotive, aerospace, banking, chemicals, insurance, mechanical engineering and retail.

We are experts applying Lean and Six Sigma Management with focus on customer experience, employee engagement and process excellence to drive transformational change.
