(On short notice instead of other presentation)

PLM-systems are expensive to purchase and

implement

Handled the wrong way they can cause more

problems than advantages

Handled the right way the gain can be huge

IVFs method for:

Gathering and communicating requirements

for evaluation of PLM-system is built on experiencefrom practical cases and studies of scientific results

The method contains 20 steps in total and I will

talk about some of the main steps of the method.


4/24

Bild 4 2006-01-30


Some of the main steps of the method are:

- Analysis of the business objectives of the target organisation- Process-mapping of critical business processes

- Evaluation and prioritisation of gains in different business

processes

- Saving of time- Saving of material

- Saving due to better process performance

- Calculation of gains in money

- Creation of demonstration scenarios for PLM-system evaluation- Communication of needs to solution providers

- Making of a cash flow calculations

- Comparison of alternatives and selection of a solution
