Roswitha Tertea is a Managing Director with Alvarez & Marsal Corporate Transformation Services in Germany. She brings more than 20 years of experience in consulting, after having built industrial expertise for more than 10 years in various large industrial companies in Germany and Switzerland. Her primary areas of concentration are process improvements across the value chain, organizational design and implementation, alongside change and business performance management.

Ms. Tertea has worked with clients across a range of industries, including manufacturing, process, automotive and waste-to-energy.

Most recently at A&M, Ms. Tertea has led the operational improvement work-stream for a global manufacturer of turbines and generators. The improvements were in conjunction with a re-structuring of the company and involved industrial footprint optimization, closure of certain sites and performance improvement of the remaining sites. The work encompassed engineering, manufacturing and service. Due to the project, the company returned from negative $100 million EBITDA to positive $30 million in the second financial year.

Ms. Tertea has also led a project in the waste-to-energy industry over a period of one year. Site assessments (11) for plants located in Spain and France were performed. Sites with the largest savings potential were selected for improvement projects that have resulted in EBITDA improvements of five to 18% through optimization of processes in production and maintenance, performance management, organizational structure and re-negotiation of contracts with clients (utilities and end-customers for recycled materials). Additionally, Ms. Tertea has been involved in a project for a private equity in the pharmaceutical industry, where she has led the evaluation of the current European footprint and the design of the future footprint, encompassing manufacturing, development, engineering, quality and the required supply chain. The improvements were targeting profitability increase from eight to 15%.

Prior to joining A&M, Ms. Tertea spent 20 years with various other consulting companies, including Roland Berger, Arthur D. Little and Celerant. She had been leading improvement projects across Europe in the manufacturing, pharmaceutical and chemical and telecoms industries.

Ms. Tertea earned a master’s degree in electronics and telecommunications from the University of Klausenburg. A German national, she is fluent in English, French, Italian and Spanish.
