Consultant / Sales Manager
Manfred Hoffmann; Carolla Hoffmann

Manfred Hoffmann , Managing Director
Carolla Hoffmann , assistant to the management


For over ten years, I have successfully provided consulting services in the areas of business analysis and
process automation. During this time I had accompanied and designed versatile projects in the role of a
business analyst, project manager or solution architect. In previous roles, I was responsible for identifying
the business requirements and drafting concepts as well as implementing and testing complex business
intelligence solutions. In the earlier projects I took over the interface function between Technology and the
Business / Finance and was always committed to achieving the planned result, taking into account the
respective relevant implementation model.

I got to know the complex topics from different perspectives as a business analyst, project manager, test
manager or solution architect and can put myself very well into the respective role. In the earlier projects I
have worked in teams organized according to Scrum as well as in those that have advanced according to
the classical waterfall principle.

The knowledge I have collected from previous projects is the advance statute to achieve good results in
improving your product. Therefore you can expect from me full dedication and a lot of personal passion
and drive in achieving goals, coordination with team members and reporting to the management. My skills
relevant to daily work such as

* Strong analytical thinking,

* Structured way of working,

* Ability to anticipate and

* Accurate, open and secure appearance in meetings and management reports

are thereby brought to bear one hundred percent.
