Today, IT-supported value added chains are far and away the determining factor of production. However, approximately half of all IT implemen-tation projects fail – because of budgetary, scheduling, scope-of-performance, expectation management or quality issues. Therefore, successful IT projects require a clear charter, consistent management and a transparent approach.

Future-oriented IT organization

Modern requirements management with regionally and internationally distributed, shared services for development, application management and operation requires functioning, competitive structures – with transparent service levels and "pay-as-you-earn" cost models.

Expert process consulting

Today, complex business processes span the boundaries between companies and technologies, integrate internal and external partners, and make systematic use of the possibilities of onsite and mobile applications and systems. So you would do better to stick with competent experts right from the beginning of your implementation.

Successful interim/crisis management

Where interim management of IT projects in ERP, eBusiness or mobile enterprise environments is concerned, we can offer you industry background, technical and business know-how, and three decades of international experience from a vast number of projects at major corporations or mid-sized companies.

Holistic quality and risk management

In IT projects, "quality" and "risks" are not concepts that are subject to interpretation and they are certainly not "overhead". They are clearly measurable and can be evaluated and controlled – on the basis of completeness, robustness, error curves, impact and likelihood of occurrence.

Groundbreaking IT strategy and technology

The demands placed on modern business management are growing at breakneck speed. In order to see the path to success laid out clearly before you, you must keep an eye on your strategic business objectives and precisely derive and control your operational projects from them.

Objective-driven program / project management

Today, IT-supported value added chains are far and away the determining factor of production. However, approximately half of all IT implementation projects fail - because of budgetary, scheduling, scope-of-performance or quality issues. Therefore, successful IT projects require consistent management and a clear course of action.
