Executive Interim Manager Siegfried Lettmann: Sales, Marketing, Product Management

About me

Since the early 90s I have been working as managing director, sales manager and division manager. Since 2012 I have been available to companies as Executive Interim Manager. I often work in international business areas and take care of business and organizational development for my clients, optimize processes and manage strategic sales initiatives, for example. In my mandates I focus on openness, transparency and clear values. I have a degree in business administration and have already received several awards for my work as an interim manager as a strategy and implementation expert. Born in Kiel, I now live in my adopted home of Salzburg. [more…]

This is important to me…

Leadership

Following my values, I lead according to the situation, taking into account my task, the specific company situation and the cultural circumstances. In doing so, I take a very goal-oriented approach, place emphasis on mutual trust, create clear responsibilities and thus unlock potential in the company. I ensure clear relationships and structures, promote order, give employees orientation and thus bring security into the company.

I have disciplinary management experience of up to 400 employees and have sales responsibility of up to EUR 700 million.

Qualifications

I invest in my further training – and thus also in your company. Because you benefit from the latest methods and expertise, which, coupled with my experience, can be transferred to you, your employees and your company in the long term.

You rightly expect that your interim manager is always up-to-date, masters modern instruments and tools and knows current developments in his field of expertise. This is exactly why regular further training is important to me: so that I can provide you with qualified and professional support. Every year I invest at least 10 days in intensive further training measures. Here is an excerpt:
