Logic models

Developing what are known as logic models (also 'program theory') proves to be very useful for goal clarification in an evaluation of a project or program. A logic model describes how the parts of a project or program contribute to goal achievement and how they interrelate. The model usually consists of the following components:

• Resources (know-how, hours of work, funds etc., everything which goes into the project and makes it possible)
• Procedures (everything done to implement the project)
• Products (what is developed, made available or provided, e.g. technologies, contents, courses, etc.)
• Results and impacts (what the project should achieve in the short-term, mid-term or long-term, e.g. media skills, employability on the labour market, etc.)
• Factors can also be specified (environmental conditions which can have a positive or negative effect on the project such as requirements of the university, technical conditions, etc.)

The following diagram illustrates the principle of a logic model:

How are logic models read? 
The various components are in "if-then" relationships: If certain resources are available, then the planned measures can be implemented. If the measures are implemented, then products will be available. If products are available, then certain results are achieved, etc.

Please check, whether …

• the logic of the project is clear: What should be achieved with which means?
• the assumptions on the cause-effect relationships are clear.
• it is clear how and why a project or program should succeed.
