My main tasks and responsibilities as a technology director are management of the technology department, managing customer relationships on a technology level and, as a member of the board of directors of Impiric the overall management of the company (which counts 120 employees in total). The biggest challenge is managing the growth of the company. In May 1998 the technology department consisted of 6 programmers and a project manager, 5 of which had a free-lance contract. In May 200 the size of the department has grown to 35 permanent staff and 8 freelancers which were successfully (and profitably) building and implementing high quality web sites for major multinational customers.
The department is now structured as a development group and a quality assurance and testing group. The later also includes a content management team, a help desk and a technical documentation role. The development group has a matrix organisation consisting of a resource manager, 5 technical project managers and a pool of software engineers. The software engineers are grouped in the following knowledge centres: HTML, scripting, Databases and OO-techniques.
The employees within the technology department have different backgrounds coming from several countries around the world. During this time I lead the design and development of a standard platform for building dynamic, database driven web sites. The platform (although largely written in Java) is based on the Microsoft products: NT, IIS and SQL server. This high performance platform is currently used by Ericcson and Ford-Europe. It includes content management and support for templating, site hierarchies, multi linguality (including for instance Chinese), personalisation and staging.
Starting March 1999 I was also appointed IT-director of the Y&R group and put in charge of the system management group of Y&R Holland. This group consists of 10 system engineers servicing 450 employees in 5 sites in Amsterdam, Hilversum and The Hague. I have re-organised the group to contain a call dispatch position, field engineers and project engineers.
